262 - Bochs benchmarking support
263 - Added emulation of Intel SSE4.2 instruction set
265 Detailed change log :
268 - Added emulation of SSE4.2 instruction set, to enable use
269 --enable-sse=4 --enable-sse-extension configure options
270 to enable POPCNT instruction only use configure option
272 - Implemented MTRR emulation, to enable use --enable-mtrr configure
273 option. MTRRs is enabled by default when cpu-level >= 6.
274 - Implemented experimental MONITOR/MWAIT support including optimized
275 MWAIT CPU state and hardware monitoring of physical address range,
276 to enable use --enable-monitor-mwait configure option.
277 - Removed hostasm optimizations, after Bochs rebenchmarking it was found
278 that the feature bringing no speedup or even sometimes slows down
280 - Merged trace cache optimization patch, the trace cache optimization
281 is enabled by default when configure with --enable-all-optimizations
282 option, to disable trace cache optimization configure with
283 --disable-trace-cache
284 - Many minor bugfixes in CPU emulation (both ia32 and x86-64)
285 - Updated CPU instrumentation callbacks
287 - Bochs Internal Debugger and Disassembler
288 - Many fixes in Bochs internal debugger and disassembler, some debugger
289 interfaces significantly changed due transition to the param tree
291 - Added support for restoring of the CPU state from external file
292 directly from Bochs debugger
294 - Configure and compile
295 - Renamed configure option --enable-4meg-pages to --enable-large-pages.
296 The option enables page size extensions (PSE) which refers to 2M pages
298 - Removed --enable-save-restore configure option, save/restore feature
299 changed to be one of the basic Bochs features and compiled by default
300 for all configurations.
301 - Added new Bochs benchmark mode. To run Bochs in benchmark mode execute
302 it with new command line option 'bochs -benchmark time'. The emulation
303 will be automatically stopped after 'time' millions of emulation
305 - Another very useful option for benchmarking of Bochs could be enabled
306 using new 'print_timestamps' directive from .bochsrc:
307 print_timestamps: enable=1
308 - Added --enable-show-ips option to all configuration scripts used to
309 build release binaries, so all future releases will enjoy IPS display.
310 - Enable alignment check in the CPU and #AC exception by default for
311 --cpu-level >= 4 (like in real hardware)

1444 - added emulation of AMD 3DNow! instructions set. (Stanislav Shwartsman)
1445 Bochs now could decode all AMD 3DNow! instructions.
1446 Most of instructions still not implemented, but the basis already presents.
1447 Configure --enable-3dnow to enable 3DNow! support.
1449 - These instructions are not implemented yet:
1450 PFPNACC_PqQq, PF2IW_PqQq, PFNACC_PqQq, PFCMPGE_PqQq, PFMIN_PqQq,
1451 PFRCP_PqQq, PFRSQRT_PqQq, PFSUB_PqQq, PFADD_PqQq, PFCMPGT_PqQq,
1452 PFMAX_PqQq, PFRCPIT1_PqQq, PFRSQIT1_PqQq, PFSUBR_PqQq, PFACC_PqQq,
1453 PFCMPEQ_PqQq, PFMUL_PqQq, PFRCPIT2_PqQq
1454 - CPUID does not report 3DNow! instruction set.
1455 - added emulation of SSE/SSE2 floating point instructions. (Stanislav)
1456 All SSE/SSE2 floating point instructions are fully implemented using
1457 free softfloat library (including DAZ support and floating point
1458 exceptions). Correctness of the emulation checked with heavily random
1460 - added emulation of SSE3 (PNI) instructions (Stanislav)
1461 Currently only 3 PNI opcodes still not implemented:
1462 FISTTP m16int, FISTTP m32int, FISTTP m64int
1463 - added P4 CPU support to CPUID instruction. (Stanislav)
1464 - fixed implementation of FXSAVE/FXRSTOR instructions. (Stanislav)

1778 Changes in 2.0 (December 21, 2002):
1780 Since the change log is hundreds of lines long, here is a very brief summary.
1781 - 2x emulation speedup!!!
1782 - added plugin devices and guis. Now you can compile with many more
1783 options, and choose between them at runtime.
1784 - added emulation of AMD x86-64, MMX, SSE, SSE2 instructions
1785 - add wxWindows port (a graphical configuration interface and display lib)
1786 and SVGAlib port (full screen display for Linux without X11)
1787 - improvements in many I/O devices: for example up to 8 hard disks/cdroms,
1788 TUN/TAP network interface, 360k floppies,
1789 - improved MacOSX/Carbon interface and updated MacOS9 port
1790 - GDB remote stub, allows symbolic debugging with Bochs simulation.
1791 - support for up to 32gig hard disk images
1793 Detailed change log follows.
1796 - manpages updated (Volker, Christophe)
1797 - install HTML rendering of docbook documentation instead of
1799 - doc/docbook/Makefile is now generated by configure script.
1800 if configure detects docbook2html on your system, it will turn on
1801 --enable-docbook and run make in the doc/docbook directory. Also
1802 make install will install documentation into $(docdir). You can use
1803 --disable-docbook to turn this off, if necessary. (Bryce)
1804 - add "make bochsdoc.tar.gz" target to create a documentation tarball.
1805 If you do "make webinst" and you have write access on SF shell server,
1806 it updates doc/docbook/* on the website (Bryce)
1807 - user documentation additions:
1808 - new options (Bryce, Volker, Christophe)
1809 - Bios tips section (Christophe)
1810 - Tuntap section (Christophe)
1811 - Serial Port section (Christophe)
1812 - "Will it Work for Me" / "Is Bochs Right for Me" sections
1814 - VESA section (Jeroen Janssen)
1815 - several documents, previously existing as separate html files, have
1817 - internal debugger section (Christophe)
1818 - gdb stub debugger section (Christophe)
1819 - WinME, WinNT, WinXP, The Hurd, Japanese Win95 install tips (Christophe)
1820 - Win95, Win98 install tips (N. David)
1821 - SB16 section (N. David)
1823 - configure script/compile/porting to other OSes/installation
1824 - added plugin architecture
1825 - plugin code written by Bryce, Christophe, Volker based on
1826 plex86's plugin code by Kevin. Testing help from Psyon and Br'fin.
1827 - Plugins are shared libraries that can be loaded on demand. Example:
1828 the serial device is implemented as a plugin. In UNIX, the
1829 serial plugin is called libbx_serial.so. When Bochs reads its
1830 configuration file, if the serial device is enabled it loads
1832 - all display libraries, most I/O devices are converted to plugins now
1833 - plugins supported on Linux, Solaris, and MacOS X using libtool,
1834 Cygwin using dlltool. On MacOSX, you must have dlcompat installed
1835 and in your include/library paths at configure time. (See .conf.macosx
1837 - we use libtool's LTDL library from libtool 1.4.2, with a number of
1838 critical bug fixes (Bryce Denney)
1839 - the Linux binary RPMs are built with plugin support
1840 - to compile with plugins, configure with --enable-plugins
1841 - the LTDL_LIBRARY_PATH variable tells Bochs where its plugins can be
1842 found. Bochs has a compile-time default for this variable which is
1843 correct if you do a make install. You would only need to set the
1844 variable if the default is wrong.
1845 - for win32 plugins we added "BOCHSAPI" in front of many classes
1846 and methods, to aid in building DLLs. This turns into __declspecs
1847 which are used when making an export library for Bochs.
1848 - allow many display libraries to be configured and compiled at
1849 a time. For example --with-win32 --with-sdl --with-rfb.
1850 Also, we added an experimental option --with-all-libs which
1851 tries to detect which --with-* options will work. If the
1852 autodetection fails, just type the --with-* options explicitly. (Bryce)
1853 - add #if's around all files which are conditionally compiled such
1854 as cdrom.cc and sb16.cc. This makes it possible to compile every
1855 source file all the time, which has the potential to simplify the
1856 configure script and makefiles. At present we only take advantage
1857 of this capability in the win32 VC++ workspace. (Bryce)
1858 - the MacOS9 port has been updated so that it works again. It had
1859 not been updated in at least 2 years, maybe more. (Christophe Bothamy)
1860 - improve support for FHS standard (Robert Millan, Volker Ruppert)
1861 See patches 551811 and 650066.
1862 - keep separate CFLAGS and CXXFLAGS for Bochs (usually a graphical
1863 program) and console programs such as bximage and niclist. Some
1864 sdl and wx compile flags were making bximage and niclist unusable.(Bryce)
1865 - add concept of cross-configuring in the configure script. If you
1866 use the --target option to generate makefiles to be used on another
1867 machine, some detection of compilers and libraries is disabled. (Bryce)
1868 - fix term compile on Cygwin, but it has to be done without -mno-cygwin,
1869 which means that several win32 features such as networking do not work.
1870 - add "-Wno-multichar" on beos
1871 - test for largefile support, and add required CFLAGS (Bryce)
1872 - add -lm when it's needed, and not when it's not (Bryce)
1873 - add configure support for 8 processors. Bochs can support up to 15
1874 with some work on the BIOS.
1875 - fix nmake makefile generation (Psyon)
1876 - improved pthread detection function from ac-archive project on SF
1877 - add installer package for Windows, using Nullsoft (Michael Rich, Bryce)
1878 - on MacOSX, add startup script that creates a text console and then
1879 runs Bochs. Also add make target to create a DMG disk image (Br'fin)
1880 - do not restart the font server on Unix/X11, if vga.pcf was already
1881 installed. On several modern machines, if you restart the font
1882 server the user has to restart X windows. (Bryce)
1883 - update most .conf.* files with modern options such as
1884 --enable-all-optimizations. (Bryce)
1885 - The MacosX .conf script adds /sw/include and /sw/lib to the compile/link
1886 path list because it is a common place to put dlcompat. Dlcompat is
1887 required when building with plugins. (Bryce)
1888 - rpms can now be built without root privileges (Bryce)
1891 - fixed up our command line options (Volker, Bryce, Christophe)
1892 Usage: bochs [flags] [bochsrc options]
1893 -n no configuration file
1894 -f configfile specify configuration file
1895 -q quick start (skip configuration interface)
1896 --help display this help and exit
1898 - configuration file (bochsrc)
1899 - There are several new options. See the documentation for more details.
1900 - config_interface: select text mode menus or wxWindows for configuration
1901 - display_library: select which display lib to use
1902 - optromimage: load optional rom images
1903 - ataN (N=0,1,2,3): up to 4 ATA controllers for hard disks, cdroms
1904 - ataN-master, ataN-slave, N=0,1,2,3: defines a hard disk or cdrom.
1905 The "ata*" options replace diskc, diskd, and cdromd, which are
1907 - floppy_bootsig_check: control the 0xaa55 signature check on boot floppies
1908 - logprefix: lets you change the format of log messages
1909 (patch by Carl Sopchak, help from Christophe)
1910 - debugger_log: log all output from bochs debugger
1911 - user_shortcut: allow you to type key combinations like Ctrl-Alt-Del
1912 - pit: control the PIT model, including realtime option to try to
1913 keep in sync with real time.
1914 - Credits: Christophe added optromimage, everything about ATA,
1915 floppy_bootsig_check, debugger_log. Bryce added config_interface
1916 and display_library. Volker did the user_shortcut button.
1917 Greg Alexander wrote the PIT model and added the realtime option.
1918 - since v1.3 we've been able to use environment variables in pathnames
1919 in the bochsrc file. Now, a few variables have default values, set at
1920 compile time, that are used if the user does not set a value. If Bochs
1921 is installed correctly, the defaults will be correct and the user will
1922 not need to override them.
1923 - $LTDL_LIBRARY_PATH is the path name where the plugins can be found.
1924 The default value comes from $(plugdir) in the makefile. This is only
1925 important if plugins are enabled. (Bryce)
1926 - $BXSHARE is the path where the BIOSes and keymaps are installed.
1927 The default value comes from $(sharedir) in the makefile. Disk
1928 images on the Bochs website will begin to use BIOS pathnames like
1929 $BXSHARE/BIOS-bios-latest. On win32, the $BXSHARE default is
1930 set by the NSIS installer and read from the registry. On MacoSX,
1931 the $BXSHARE default is set to the path containing bochs.app.
1932 (Bryce, Volker, Br'fin)
1933 - new option in the configuration interface to reset all bochsrc
1934 settings to initial defaults. A reset occurs just before reading
1935 a new configuration file, so that leftover parameters from a
1936 previous configuration do not affect the new configuration. Also,
1937 you can request a reset using the configuration interface. (Volker, Bryce)
1938 - ne2k line can now specify a script to set up the interface (Christophe)
1939 - on Unix, also search /etc/bochsrc (Bernhard Bablok)
1940 - you can use #include in the bochsrc to read configuration from other
1944 - speed optimizations from Kevin Lawton, yielding around 2x speedup
1945 - guest2host_tlb : for entries in the paging TLB which point to normal
1946 physical memory pages, a pointer to the host address of the emulated
1947 physical memory (from malloc()) page is stored in the TLB entry. In
1948 many cases, this pointer can be used in memory accesses to directly
1949 read/write the guest memory address. In exceptional cases, the physical
1950 memory access routines are used. Turn on with --enable-guest2host-tlb.
1951 - repeat IO/string : for some variants of repeatable IO and string
1952 instructions, the segmentation and paging checks are done in batch along
1953 with the data transfers, constrained within page boundaries and the
1954 segment limits. Turn on with --enable-repeat-speedups.
1955 - icache : The structure holding instruction decode information was
1956 reduced to 32 bytes. 24 bytes for the actual decode data, and 4 each
1957 for pointers to the address resolution routine (not always needed) and
1958 the instruction emulation routine. With a reasonably small
1959 per-instruction decode size, an instruction cache (iCache) was created,
1960 which is simply a hash table. The main cpu loop looks in the table
1961 first; if the instruction has already been decoded, execution can begin
1962 immediately without decoding. Turn on with --enable-icache.
1963 - host specific asm : when compiling on an x86 platform, use of
1964 x86-specific asms can be enabled to accelerate several facets of
1965 emulating instructions. For example, the EFLAGS values are much more
1966 efficient to calculate when the actual x86 instructions are used to
1967 generate the EFLAGS values. Turn on with --enable-host-specific-asms.
1968 (Kevin, with help from Jas Sandys-Lumsdaine)
1969 - if you want to enable all the speed optimizations that we believe
1970 to be stable, use --enable-all-optimizations. The release binaries
1971 are built with this option.
1972 - add support for AMD's x86-64 instruction set. To enable, configure with
1973 --enable-x86-64. The AMD x86-64 support is about 90% complete and is
1974 still experimental. We've implemented the core x86-64 instruction set and
1975 the changes to the rest of Bochs necessary to operate in long mode, but
1976 we've still to implement checking for canonical 64 bit addresses. The code
1977 has been tested on a limited number of test programs. It has been able to
1978 successfully boot a x86-64 Linux kernel and run a 64 bit userland
1979 application. It has also successfully run a DOS based 64 bit protected
1980 mode test application. (Peter Tattam, with merge/bugfix help from Kevin
1981 Lawton and Bryce Denney)
1982 - add MMX support. To enable, configure with --enable-mmx.
1983 (Stanislav Shwartsman)
1984 - add SSE and SSE2 support. To enable, configure with --enable-sse=1
1985 or --enable-sse=2. (Stanislav)
1986 - fixed the behaviour of the bcd instructions AAM, AAD and DAA based on
1987 SF patch #537146 (Volker)
1988 - stop printing an error for VERR/VERW. According to the i386 opcode
1989 description there is no error present. (Volker)
1990 - fix bug [ 625878 ] reset doesn't reset something(?). Fix cpu reset
1991 when executing a rep instruction (Christophe)
1992 - use accessors methods for CFLAGS and several other registers, so that
1993 the implementation can be changed transparently later (Bryce, Stanislav)
1994 - add support for page size extensions, also known as 4meg pages.
1995 Turn on with --enable-4meg-pages. (Kevin Lawton)
1996 - add support for page global extensions. Turn on with
1997 --enable-global-pages. (Kevin)
1998 - add support for physical address extensions. Turn on with --enable-pae.
2000 - implement RDMSR and WRMSR. not all MSRs are supported (Zwane Mwaikambo)
2001 - new configure option --enable-ignore-bad-msr, which makes unrecognized
2002 MSR reads and writes into just a warning
2003 - fix PIC/APIC interrupt problem that caused Linux 2.4.19 to hang
2005 - CMPXCHG8B patch (Michael Hohmuth)
2006 - EFLAGS are now stored in the same form as the native EFLAGS on an x86,
2007 so that we can use native machine instructions in some cases (Kevin)

2016 - rewrote pc_system timers (Kevin)
2018 - this new device handles the panic/error/info/debug messages sent
2019 by the Bios and VGABios. It was previously done in the unmapped device.
2021 - implementation of the function READ TOC for cdrom image files. (Volker)
2022 - function capacity() for win32 fixed. Now it returns the number of blocks
2023 instead of bytes. (Volker)
2024 - added multiple cdrom support for win32 (NT/2000 version untested). The
2025 ASPI version uses the cdrom drives in the system's order. Drive letters
2026 are not used by ASPI. (Volker)

2165 option using menus and dialog boxes. There is also the beginning of
2166 a wxWindows graphical debugger, but it needs a lot of work before it
2168 - renamed control.cc to textconfig.cc. Now we're calling it a
2169 text configuration interface, instead of a control panel.
2172 - Even though we've had them for years, the term "display library" is new in
2173 release 2.0. In the gui directory, Bochs has a number of different C++
2174 files which you can select to display the text and graphics on the
2175 simulated monitor. Each of these is a display library. The display
2177 x use X windows interface, cross platform
2178 win32 use native win32 libraries
2179 carbon use Carbon library (for MacOS X)
2180 beos use native BeOS libraries
2181 macintosh use MacOS pre-10
2182 amigaos use native AmigaOS libraries
2183 sdl use SDL library, cross platform
2184 svga use SVGALIB library for Linux, allows graphics without X
2185 term text only, uses curses/ncurses library, cross platform
2186 rfb provides an interface to AT&T's VNC viewer, cross platform
2187 wx use wxWindows library, cross platform
2188 nogui no display at all
2189 - it is now possible to compile Bochs with support for many different
2190 display libraries and select the one to use at runtime (even without
2191 plugins). See the display_library directive in .bochsrc.
2192 - add new svgalib display library by Igor Popik
2193 - fix bug [ 614724 ] SDL can get stuck in full screen mode
2194 display libraries such as SDL which have a full screen mode can be
2195 dangerous, if Bochs does not switch back to normal display mode at
2196 the right time. This is fixed for SDL and the new svga.
2197 - keymap support added in SDL interface (Bryce, Volker)
2198 - new keymap files: SDL keymaps for US and DE keyboards, X11 keymap
2199 for Danish keyboard.
2200 - use keyboard mapping for keyup messages too
2201 - renamed almost all references to data type "Boolean" to "bx_bool".
2202 The Boolean data type was defined in Carbon.h headers, and conflicted
2203 with Bochs's definition. See bug [ 618388 ] Unable to boot under MacOS X
2204 Exceptions: When talking to the Carbon library, you must use Boolean.
2205 Also, siminterface.h uses standard "bool" instead of bx_bool.
2206 - "User" button added in toolbar. It can send keyboard shortcuts to
2207 the guest OS. (Volker)
2208 - snapshot improvement and memory leak fixed (Volker)
2209 - testing framework, based on comparing screen content, added (Greg)
2210 - term display library:
2211 - support for color terminal, function keys, clear screen (Volker)
2212 - solaris compilation problem (bug #613393) fixed (Bryce)
2213 - win32 display library:
2214 - use native win32 toolbar for headerbar, use system palette (Volker)
2215 - many Carbon interface improvements:
2216 - patch [ 549248 ] Fix Carbon key & menu handling (Chris Thomas)
2217 - partial keymap support, copy&paste, menu items fixed, new toolbar
2218 behavior, dialog box display for panics (Br'fin)
2219 - sdl display library:
2220 - keyboard fixes and key mapping added (Bryce)
2221 - when captured, the mouse is forced to stay in the window. fix bug
2222 [ 619283 ] SDL: os mouse pointer leaves the window (Bryce)
2223 - x display library:
2224 - bug [ #537593 ] vga font not being found fixed. If vga font not
2225 found, search for a font called "-*-vga-*" (Bryce)
2226 - keyboard problems fixed (Bryce, Christophe)
2227 - beos platform, any display library: add a nice icon to the executable
2231 - wxWindows is a cross-platform C++ user interface library which you can
2232 download for free at http://wxwindows.org. wxWindows provides C++
2233 classes for all sorts of GUI controls (buttons, menubars, etc.) and
2234 implements all of them using the native controls on the platform.
2235 - The new wxWindows port of Bochs provides both a graphical configuration
2236 interface (for editing bochsrc options) and a display. It was
2237 written by Bryce Denney, Don Becker, Dave Poirier, and Volker Ruppert.
2238 - In release 2.0, we concentrated on making the wxWindows port as stable
2239 and functional as the other interfaces. wxWindows provides a great
2240 toolbox that we can use to make Bochs easier to learn and use.
2241 - wxWindows supports charmap changes, keyboard mapping, cut and paste,
2242 text and graphics modes, text mode cursor size, and mouse (Volker, Bryce)
2243 - To compile Bochs with wxWindows, you should install wxWindows 2.3.3
2244 or later. Then configure Bochs with --with-wx.
2245 - if you have multiple versions of wxWindows installed (e.g. a debug
2246 and a release version), you can set $WX_CONFIG before configuring
2247 to select between them. (Bryce)
2250 - [ 609616 ] remote GDB stub
2251 add GDB Stub support from Johan Rydberg, with bug fixes by Stu Grossman
2252 - add hooks for external debugger for win32. The external debugger
2253 that connects to Bochs is distributed in
2254 build/win32/tattam-external-debugger.zip in binary form. Turn on
2255 with --enable-external-debugger. (Peter)
2256 - add "debugger_log" option to bochsrc, which logs all debug output
2257 into a file. feature [ 629068 ] (Christophe)
2258 - debugger is now usable in fullscreen SDL and SVGA guis. It will
2259 switch back to text mode for each debug prompt (Bryce)
2260 - disassembly output cleaned up and improved
2261 (Kernel Panic, Peter Tattam, Jonathan Shapiro, Luiz Henrique Shigunov)
2262 - fix [ 628806 ] debug: x/c prints unprintable chars (Bryce)
2263 - add the beginnings of a wxWindows debugger. Not ready for mainstream use
2264 yet. CPU register display is implemented, and you can type any debugger
2265 command you want into the Debug Console window. (Bryce)
2266 - add help command (Alexander Krisak)
2267 - symbol table lookups cleaned up a bit (Bryce)
2268 - displays the address of the caught watchpoint, feature #435271 (Dave)
2269 - remove obsolete "loader"
2272 - fixed bug [ 487758 ] bximage fails on file creation >2048meg
2273 Bximage should now work up to 32gig. (Bryce)
2274 - on win32, both bximage and niclist now ask the user to press
2275 return before exiting, so that you have time to read the results
2276 before the window disappears. (Bryce)
2278 -------------------------------------------------------------------------
2279 Changes in 1.4.1 (June 22, 2002):
2281 - now cdrom is enabled in configure, unless you specifically disable
2282 it with --disable-cdrom. (Christophe)
2283 - fix compile error in main.cc when SMP or APIC is enabled (Dave)
2284 - the runtime menu now displays 11 (continue) by default (Bryce)
2285 - initialize DMA controller before floppy and SB16
2286 - fix DMA panic when installing win95 (Volker)
2287 - first character of the vga bitmap is blank on win32 (Volker)
2288 Before, it was incorrectly coded as a '@'.
2289 - AltGr key on European keyboards works now on win32 (Volker)
2290 - fix problem with console/serial port on Bochs exit (Volker)
2291 - enable serial port for GNU and GNU/Linux (Volker)
2292 - small documentation fixes (Volker)
2293 - remove unnecessary include statements for X11 (Volker)
2294 - italian keymap added (Emanuele Goldoni)
2295 - fix win32 ethernet frames error. It will no longer reject packets
2296 that are less than 60 bytes long. (Peter Tattam)
2298 - win2k cd-boot (Christophe)
2299 - emm386 crash (Dave)
2300 - cs=0 at boot time (Christophe)
2301 - keyboard failure in scandisk (Dave)
2302 - fix bug in forming the 64-bit APIC base address from two 32-bit registers.
2303 A compiler warning in cpu/proc_ctrl.cc pointed this out.
2304 - fix default choice in the runtime options menu
2306 -------------------------------------------------------------------------
2307 Changes in 1.4 (March 27, 2002):
2309 - Boot from CDROM! Christophe Bothamy added partial El Torito support in
2310 rombios.c, which allows Bochs to boot cdroms. Booting from win2k or winXP
2311 cdrom is not supported yet. The default BIOS includes El Torito functions.
2312 the boot line must say "cdrom".
2315 - implementation of int13 diskette function 5 (format track) (Volker)
2316 - initialisation of PIC and DMA-2 added to POST code (Volker)
2317 - configure script (Bryce Denney)
2318 - the configure script now detects your platform and provides a default
2319 GUI and the required compiler flags. All supported platforms should
2320 compile with simply "configure" and "make".
2321 - default guis by platform:
2322 - win32/windows/cygwin: win32 gui
2323 - MacOS X: carbon gui
2324 - MacOS 9 or earlier: macos gui
2326 - AmigaOS: amigaos gui
2327 - all other platforms: X windows gui
2328 - compile arguments supplied by configure script
2329 - win32: too many to list here; see documentation
2330 - cygwin: -mno-cygwin -DWIN32
2331 - MacOS X: -fpascal-strings -fno-common -arch ppc -Wno-four-char-constants
2332 -Wno-unknown-pragmas -Dmacintosh
2333 - the --with-GUINAME configure option is only needed if you want to override
2334 the default GUI. This is the only way to use the Term, RFB, and SDL
2337 - added VESA BIOS Extensions code by Jeroen Janssen (banked mode only, LFB
2339 - vga memory read/write functions in text mode fixed
2340 - implementation of CGA mode 320*200*4 (patch from Sebastien Bechet)
2342 - updated Christophe Bothamy's LGPL VGA BIOS to version 0.3a. This consists
2343 of a bug fix for function ah=13 and VBE support by Jeroen Janssen.
2345 - chipmem read/write limit fixed (Mike Lerwill)
2346 - writing a byte in 16-bit mode now possible (Mike Lerwill)
2347 - new ethertap interface for Linux, which allows Bochs to talk to
2348 the local machine and the internet (Bryce Denney)
2349 - NE2000 is now enabled by default on Win32, Cygwin, and Linux compiles
2350 in the .conf.* scripts and release binaries.
2351 - fix check for auto transmit disable, which was checking the wrong bit
2354 - niclist.exe has been revised to work on more Windows versions, and it
2355 suggests a usable ne2k line (Dean Payne)
2356 - fix timeout setting so that ne2000 does not slow down the whole
2357 simulation (Don Becker)
2358 - bug fix: be able to handle multiple packets that arrive at once
2361 - cdrom button: click this to notify Bochs when you changed the CDROM (Volker)
2362 - snapshot button: saves the text on the Bochs screen into a file called
2363 snapshot.txt (Volker)
2364 - copy button: on Win32 and X windows, copy the text on the Bochs screen
2365 to the clipboard (Volker)
2366 - paste button: on Win32 and X windows, paste the characters on the
2367 clipboard into the Bochs window. This requires keyboard_mapping to
2368 be enabled. (Bryce Denney)
2369 - improved text mode cursor for Win32, X11, and SDL (Volker)
2370 - new SDL interface (Dave Poirier, debugging by Christophe, Volker, Bryce)
2371 SDL is a graphics library that has works on many platforms. This interface
2372 is experimental, and is missing a few features of the standard Bochs
2373 interfaces: extended keys (arrows, keypad).
2374 - MacOS X: add MacOS X carbonized event handlers by Jeremy Parsons
2375 - X windows: when not enough colors can be allocated, force use of
2376 private colormap (Bryce Denney)
2377 - bug #490570 fixed: OUTB set and command 0xaa encountered (Dave Poirier)
2379 - completed keyboard emulation with the implementation of the three scancodes
2380 sets (mf1, mf2, mf3) with or without translation. This is based on Ludovic
2381 Lange's plex86 keyboard patch. (Christophe Bothamy)
2382 - added a "keyboard_type" option, that defines the answer to an "identify
2383 keybord" request to the keyboard controller. The available values are
2384 "xt","at","mf". (Christophe Bothamy)
2385 - added an optional keyboard_mapping option that enables to use your
2386 country specific keyboard with Bochs. If enabled, the keymap file must be
2387 specified in bochsrc. The available keymaps are US, German, Spanish and
2388 French for PCs running X11. Contributions are welcomed. (Christophe
2390 - added Windows(tm) key definitions (Volker Ruppert)
2391 - added paste button, which causes the emulated keyboard to type characters
2392 from the system clipboard. This only works when keyboard_mapping is
2393 enabled. (Bryce Denney)
2395 - bug fix: win32 could not read a cdrom image file
2396 - eject cd support for linux (patch from Petr Stehlik)
2398 - changing cdrom media is possible now with CDROM button
2399 - sound blaster(tm) emulation (Volker)
2400 - you can use --enable-sb16=freebsd now
2401 - 16-bit DMA controller added
2402 - 16-bit mode of the SB16 implemented (output to file works)
2403 - floppy drive (Volker Ruppert)
2404 - implementation of the floppy command 'format track'
2405 - implementation of read / write operations with MT=0
2406 - behaviour of a few floppy commands fixed
2407 - floppy reset behaviour fixed
2408 - lots of other fixes
2409 - fixed bug [ #468340 ] pic:slave: OCW3 not implemented. Now the slave PIC
2410 supports all the modes that the master PIC does, and nobody will see this
2412 - serial port (by Volker Ruppert unless noted)
2413 - improved IRQ handling
2414 - now Windows 95 serial driver works correctly
2415 - fixed the return value of the MCR (loopback bit)
2416 - interrupt reasons LSR change and MSR change implemented
2417 - the number of data bits is considered when sending data
2418 - all serial port changes are tested in loopback mode only
2419 - serial port emulation fixed for FreeBSD and OpenBSD (Stu Grossman)
2420 - fix receiver poll frequency so that it doesn't slow emulation (Stu Grossman)
2422 - when tracing, print the instruction just before it is executed, instead
2423 of just after (Greg Alexander)
2424 - after a triple-fault panic, you can now return to the debugger
2425 - symmetric multiprocessor (SMP) simulation
2426 - no more panic if you read the EOI register
2427 - fixed default destination format in local APIC
2428 - fix SMP instruction tracing in bochs debugger
2429 - fix deadlock when debugger enabled and all processors HLT
2430 - MSR support added by Zwane Mwaikambo
2431 - simulation of interrupts is more accurate (Volker)
2432 - implemented edge triggered interrupt mode
2433 - added functions raise_irq() and lower_irq()
2434 - programmable interrupt timer (Greg Alexander)
2435 - fixed the PIT gate and improved the PIT printing options
2436 - experimental real-time PIT
2437 - parallel port improvements (Volker Ruppert)
2438 - bug fix: hard disk errors caused by overflowing imul in the BIOS code.
2439 Sebastian Bechet and Peter Tattam tracked it down and fixed it.
2440 - fix some memory leaks (patch from Darko Tominac)
2441 - Double-Word IO is supported for ATA devices
2442 - fix bash-specific syntax in install-x11-fonts script
2443 - print stack_return_from_v86 error only the first 100 times
2445 -------------------------------------------------------------------------
2446 Changes in 1.3 (December 10, 2001):
2447 - networking works on Windows and Linux platforms
2448 - emulated cdrom can now read from ISO image files, on any platform.
2449 - new PIT model by Greg Alexander which is much more complete than the
2450 old one. The new PIT is used by default, but you can switch back to
2451 the old one if you configure with --disable-new-pit.
2452 (PIT = 8254 programmable interrupt timer)
2453 - new configuration menus by Bryce Denney, which allow you to change any
2454 bochsrc option using text menus, then save the configuration into
2455 a new bochsrc file for later use. You can disable the new code using
2456 configure --disable-control-panel. Also you can use the command
2457 line arguments -nocp or -nocontrolpanel. Also, there is a new
2458 "Config" button on the GUI that allows limited changes to the
2459 configuration at runtime, such as changing the floppy disk.
2460 - add docbook documentation directory in the sources under doc/docbook.
2461 The transition from HTML to docbook documentation is still in progress.
2462 - Add new log action "ask", as shown in these example bochsrc lines:
2465 When an event occurs which is set to "ask", you get a beep and message
2466 on the text terminal that asks what you want to do. Choices are: continue,
2467 continue and disable future messages from this device, quit immediately,
2468 or segfault (where abort() function is available). If compiled with
2469 --enable-debugger, you can also choose to enter the debugger.
2470 - Parallel port emulation cleaned up by Volker Ruppert. See .bochsrc for
2471 syntax of new parport1 line in bochsrc.
2472 - PCI support improved by Volker Ruppert, including BIOS changes. Still
2474 - floppy controller returns a proper error response if you try to write
2475 a read-only disk image. For systems such as DOS that actually use the BIOS
2476 services, it was also necessary to add code in int13_diskette_function to
2477 recognize a write-protected error and return the correct error status code
2479 - the ROM BIOS now prints panic messages to the console. Thanks to Cliff
2480 Hones for his console display code.
2481 - the ROM BIOS detects nonbootable disks (Barry Allard), and prints a message
2482 on the console. Barry Allard's patch who helped with checking the boot
2484 - LBA support added for hard disks. (Not tested very much.)
2485 - add dependencies to makefiles
2486 - logging code moved into a separate file, logio.cc
2487 - new option --enable-slowdown-timer, by Greg Alexander, which kicks in if
2488 Bochs simulation time starts to run faster than real time. This helps to
2489 keep the Bochs clock in sync with the real clock when the CPU is mostly
2491 - new option --enable-iodebug, by Dave Poirier, which creates an I/O
2492 interface to the debugger. This lets you write software to be emulated
2493 in Bochs which can turn on instruction, register, or memory tracing
2495 - improved detection of readline in configure script
2496 - configure substitutes the version number into many files, instead of
2497 using sed in the makefile. There are still a few uses of sed remaining.
2498 - you can now use environment variables in bochsrc values. For example,
2499 diskd: file="$BOCHS_IMG/diskd.img", cyl=615, heads=6, spt=17
2500 - configure with --prefix=PATH works now
2501 - running configure from a different directory works now, thanks to
2502 a patch from Edouard G. Parmelan
2503 - fix [ #433759 ] virtual address checks can overflow.
2504 > Bochs has been crashing in some cases when you try to access data which
2505 > overlaps the segment limit, when the segment limit is near the 32-bit
2506 > boundary. The example that came up a few times is reading/writing 4 bytes
2507 > starting at 0xffffffff when the segment limit was 0xffffffff. The
2508 > condition used to compare offset+length-1 with the limit, but
2509 > offset+length-1 was overflowing so the comparison went wrong.
2510 - cmpxchg8b patch from Michael Hohmuth <hohmuth@innocent.com>
2511 - apply patch from Thomas Fitzsimmons <fitzsim@cygnus.com> to fix compile
2512 problems when BX_SUPPORT_PAGING and BX_USE_TLB are turned off
2513 - fix bug introduced in 1.2.1 which caused spurious exceptions.
2514 See patch #439314, Exception 1 (debug) on HALT, from
2515 thomas.petazzoni@meridon.com.
2516 - add panic in ctrl_xfer32.cc where the IRET32 implementation is broken.
2517 This only happens if you are NOT in vm8086 mode or protected mode.
2518 The intent is to warn people when they are getting bad emulation, and
2519 encourage people to report how they got to that point.
2520 - apply patch from Santiago Bazerque. See this bug report:
2521 [ #463018 ] retf not removing parameters sometimes
2522 - fix bug [ #461730 ] IRETD causes problems if NT-flag is set
2523 reported by Peter Lammich.
2524 - apply patch [ #455014 ] CR0 bug in 80486, described as:
2525 > In the register CR0, when the bit PM is enabled, the bit 4 is 0
2527 - apply patch from Mike Rieker <mrieker@o3one.org> associated with this bug
2528 report: [ #480422 ] gdt 'accessed' bit
2529 - in task_switch when it tried to ensure that the old TSS was paged in,
2530 it actually used the new TSS address, fixed.
2531 - updated the instrumentation code, and added a working example. To try
2532 it, configure --enable-instrumentation=instrument/example1. Then when
2533 you run bochs, you will get one line for each instruction PC and for
2534 each I/O access in a new file called bxevent.txt.
2535 - set a bit in the CMOS that says the processor has an FPU. This is
2536 from patch [ #455006 ] Device byte is not initialized aptly.
2537 Author did not leave their name.
2538 - add logging code to the "null ethernet" which does not require host OS
2539 support. All this does is print the outgoing packets from the guest OS.
2540 - cleanup of log functions (Todd Fries)
2541 - add BX_ERROR for every command in ATAPI-6 that bochs does not support.
2542 I still need to do add some commands from older specs that are obsolete
2543 (and not listed) in ATAPI-6. Commands that aren't in the spec will still
2545 - only put 0xf into the 2nd hard disk field when the cdrom is not present.
2546 This is a patch from Volker Ruppert <Volker.Ruppert@t-online.de>, who
2547 comments: "The fdisk command reports an unusable second harddisk if the cdrom
2548 is enabled. This patch helps, but I don't know if it is the right way."
2549 - make hard disk code return error codes when data is not available instead
2550 of just panicing. In particular, if the logical sector is out of bounds
2551 or the disk image cannot be read/written at the desired offset, we now
2552 abort the ATA command and return an error code. Many of the old BX_PANIC
2553 messages are turned to BX_ERROR, so they will still appear in the
2554 log, but now the device model will try to communicate this fact to
2555 the OS instead of simply giving up.
2556 - don't blindly reject odd length atapi commands. There are cases when
2557 it's really ok according to ATA-4.
2558 - for big endian machines, reversed the bit fields in interrupt_reason.
2559 This was pointed out by Nicholai Benalal.
2560 - extended keyboard improvements by Dave Poirier
2561 - major mouse patch from Dave Spring, that implements several missing
2563 - commit keyboard patch from David Haslam <dch@sirius.clara.co.uk>
2564 posted to mailing list, that addresses the problem of each key press
2565 printing ^@. See cvs log for details.
2566 - mouse performance fixes by Greg Alexander and Robb Main
2567 - NE2000 fixes by Frode Vatvedt Fjeld, ecelca@yahoo.com, Greg Alexander,
2568 and angelos@openbsd.org.
2569 - fix bug [ #468340 ] pic:slave: OCW3 not implemented. Some event handling
2570 code appeared in the master pic but not the slave pic.
2571 - fix compile problems in SB16 code, related to fpos_t being treated as
2573 - patch from Volker Ruppert <Volker.Ruppert@t-online.de> to fix
2574 midi output file so that winamp can play it.
2575 - some cleanup of serial code by Todd Fries and Volker Ruppert, but it
2579 - commit patch from David Haslam <dch@sirius.clara.co.uk>
2580 [ #455763 ] Cursor trail with DOS Edit/Minix vi
2581 - error for missing fonts now points to the documentation
2582 - new option --enable-idle-hack, by Roland Mainz, which makes Bochs more
2583 friendly toward other processes when its CPU is idle. Presently,
2584 this option is specific to X windows.
2587 - now Windows 95/98/ME can read the physical cdrom (Don Becker)
2588 - The default configuration for Win32 VC++, given in .conf.win32-vcpp,
2589 now enables the NE2000 and renames all .cc files to .cpp. This keeps VC++
2590 happy but may make it hard to use CVS.
2591 - The default configuration for Cygwin, given in .conf.win32-cygwin, now
2592 enables cdrom and SB16.
2593 - See "new docs" on the web site for compile instructions for VC++ and Cygwin.
2594 - The sources include a VC++ workspace, in addition to the old "nmake"
2596 - ethernet support (emulated NE2000 card), coded by Don Becker. This
2597 implementation requires a library called WinPCap, which you can
2598 download from http://netgroup-serv.polito.it/winpcap.
2599 - new utility called niclist.exe which lists the ID number of all your network
2600 cards (well probably you just have one). The ID be used when setting up your
2602 - patch [ #466403 ] make text colors more accurate. The author did not leave
2604 - fix GUI bug [ #452159 ] win32: mouse stuck if bochs win partly off screen
2605 Now we center the mouse periodically, whether or not the mouse has
2606 wandered outside of the window or not.
2607 - event handler recognizes the extended keycode flag
2608 - fixes for raw floppy and floppy disk images (Don Becker)
2611 - Ethernet (emulated NE2000 card) now works in Linux! Contributed by
2612 splite@purdue.edu. This has been tested using host OS kernel 2.2.14, and
2613 works with telnet, ftp, irc, lynx, etc. Because it is a packet filter
2614 solution, you aren't able to talk to the host machine, only to other
2615 machines on the network.
2616 - The default configuration for Linux, given in .conf.linux, now enables
2618 - RPM build process configures with --prefix=/usr so that everything is
2619 installed in /usr/bochs instead of /usr/local/bochs.
2620 - DLX Linux disk image is now installed so that only root can write it, to
2621 avoid security problems. When you run the bochs-dlx script, it creates a
2622 local copy in your home directory and then runs it.
2623 - code that determines the capacity of a cdrom now works for both ATAPI
2624 and SCSI drives (splite@purdue.edu)
2625 - applied patch from bochs@sigint.cs.purdue.edu. The comments are:
2626 > The Linux 2.4.5 CD-ROM driver sends a READ_DISC_INFO command which caused
2627 > an "unrecognized ATAPI command" panic. Looks like READ_DISC_INFO is only
2628 > recognized by CD-R and CD-RW drives, so I ignore it for now.
2630 Amiga MorphOS specific:
2631 - Bochs now compiles and works on Amiga MorphOS. Configure with
2632 --with-amigaos. For AmigaOS only, see .bochsrc for use of fullscreeen and
2633 screenmode options. The Amiga MorphsOS is written and maintained by
2634 Nicholai Benalal <nicholai@chello.se>.
2635 - raw cdrom supported if you configure with --enable-cdrom
2638 - Bochs compiles and works on BeOS. Configure with --with-beos.
2639 Bernd Thorsten Korz <bernd.korz@insidebeos.de> maintains the BeOS port.
2640 - raw cdrom supported if you configure with --enable-cdrom
2643 - Bochs now compiles and works on MacOS X. Configure with --with-carbon.
2644 Emmanuel Mailliard <e.rsz@libertysurf.fr> ported the Macintosh code to the
2646 - The MacOS X application is built using (gasp) mkdir, copy, and rez.
2647 Surely this is not the right way, but it works.
2648 - raw cdrom supported if you configure with --enable-cdrom
2651 - apply patch.rfb-mouse by MURANAKA Masaki (monaka@users.sf.net)
2652 see this source forge bug [ #457968 ] Strange mouse motion on RFB
2653 - add a retry loop in RFB code, so that if port 5900 is not available
2654 it can try 5901, etc.
2657 - do a vga update whenever you print a debugger prompt.
2658 - added debugger command "info fpu" that prints the FPU registers. If you
2659 do "info all" you get cpu and fpu registers.
2660 - added debugger command "info ne2k" which prints all the registers
2662 - add ability to do register tracing and flag tracing (Dave Poirier).
2663 Try the trace-reg-on and trace-reg-off commands.
2664 - instruction trace now includes time ticks
2665 - fixed problems in which bochs compiled with debugger measured time
2666 differently from bochs compiled without debugger. Also when instruction
2667 trace was enabled, breakpoints and control-C did not work. Also,
2668 breakpoints at the beginning of an interrupt handler did not work.
2670 -------------------------------------------------------------------------
2671 Changes in 1.2.1 (June 12, 2001):
2672 - more work on makefile for building RPMs
2673 - [ #432382 ] build debian packages patch
2674 add build/debian directory from Rob Lemley <rjlemley@calypsoblue.org>
2675 which allows us to make Debian packages!
2676 - optimize for speed when simulating one processor. Now 1-processor
2677 performance should be equivalent to 1.1.2.
2678 - [ #425640 ] sb16 assumes fpos_t is long int
2679 This fixes compiles of iodev/sb16.cc on linux systems with newer libraries
2680 in which fpos_t is not an integer.
2681 - [ #432488 ] SMP:assert "n_logfn < MAX_LOGFNS" fails
2682 increase MAX_LOGFNS since we ran out of them on an SMP simulation with
2684 - changes to compile clean on cygwin:
2685 - don't use the WIN32 snprintf define for cygwin
2686 - add ssize_t definition for cygwin
2687 - only compile "struct timeval tval" if select is available
2689 - [ #432491 ] SMP: CPUID says no APIC feature
2690 clean up inconsistent use of BX_SUPPORT_APIC and BX_APIC_SUPPORT, which
2691 caused the CPUID to report no APIC was present
2692 - [ #431025 ] --enable-external-device-models broken
2693 removed configure options for external-device-models and
2694 external-cpu-memory. These don't work and aren't going to be fixed.
2695 - [ #429448 ] configure: -lreadline when not there
2696 Now configure allows you to choose not to use readline, even if it's found
2698 - [ #428915 ] apply extended keyboard patch
2699 extended keyboard patch by Dave Poirier <eks@void-core.2y.net>
2700 - [ #428626 ] if no X11 found, configure&make fails
2701 Now configure halts if X windows is selected but no X libraries are found.
2702 - updated rombios to version 1.13. This fixes several problems:
2703 - [ #430472 ] DOS HIMEM "A20 line" error
2704 This problem was apparantly caused when Bryce added a function that prints
2705 the BIOS version, and he called it too early in the boot process. Now the
2706 same function is called later, and it doesn't break the A20.
2707 - [ #431010 ] SMP structure overwritten in v1.2
2708 SMP structures were getting overwritten by BCC-generated data,
2709 preventing SMP operating systems from detecting that other processors
2711 - [ #431016 ] bios: SMP struct has wrong entry count
2712 SMP structure had the wrong entry counts
2713 - very minor doc updates (typos, replace broken link to mtools info)
2714 - quit when the user clicks the power button, even if they have disabled
2716 - win32 now defaults to having mouse capture mode turned off. For new users,
2717 it would be distressing for their mouse cursor to disappear until they
2719 - [ #428222 ] vga font not installed
2720 added script called "install-x11-fonts" which should help people install
2721 the VGA font on X windows systems, if it isn't already there.
2723 -------------------------------------------------------------------------
2724 Changes in 1.2 (June 3, 2001):
2725 - [ #427259 ] rombios HALT calls don't print
2726 Fixed bios/rombios.c HALT macro so that it writes the line number of the
2727 panic to the PANIC_PORT (port 0x400) and then does NOT do a halt
2728 instruction. Also changed iodev/unmapped.cc so that the line number written
2729 to PANIC_PORT is displayed as a BX_PANIC message. Because the HALT
2730 macro now triggers the normal panic behavior, it can be controlled by
2732 - [ #429016 ] crash if no hard drive
2733 rombios used to call HALT macro if no hard drive was found. Now it only
2734 calls HALT if a hard drive has an illegal geometry.
2735 - [ #425388 ] include source for simple disk img tool
2736 [ #428478 ] mkimg tool creates image 1 byte too big
2737 Added bximage tool, which makes empty floppy and hard disk images.
2738 It is now included in the top level Makefile, so it will get built
2739 by default on all platforms.
2740 - [ #426036 ] eth_fbsd.cc compile problem on solaris26
2741 added configure test so that "configure --enable-ne2000" only
2742 includes the Berkeley Packet Filter code (eth_fbsd) if the header
2743 file <net/bpf.h> can be found. If you don't have BPF the ne2000
2744 will not actually move packets, but at least it will compile clean now.
2745 - [ #428214 ] 1.2.pre1 need documentation for binaries
2746 Write windows and linux specific documentation to be installed in
2748 - [ #429258 ] disable RESET for version 1.2
2749 Since soft reset was not completely working, I reverted the reset patch.
2750 Now it does panics on reset instead of trying to reboot, as the old
2752 - [ #428222 ] Should the linux RPM install vga font?
2753 now font/vga.pcf will be installed in the RPM package
2754 - [ #429020 ] stop renaming the BIOS!!!
2755 new BIOS changes are now in BIOS-bochs-latest, instead of a BIOS
2756 whose name changes every time we change anything! To help distinguish
2757 different BIOS versions, the BIOS now prints its RCS Id into the
2759 - [ #428625 ] compile problem if SHOW_IPS is on
2760 removed extra paren that broke SHOW_IPS
2761 - [ #428219 ] PCI doesn't compile with SMF=1
2762 - [ #429375 ] pthreads detection broken
2763 - [ #429073 ] configure: if no X11, makes bad config
2764 - [ #429229 ] install current .bochsrc in binary rels
2765 - install Tim's man pages on linux RPM
2766 - BIOS prints messages in log in case of boot failure
2767 - rewrote instructions for compiling in win32 (win32.txt)
2768 - fixed link in HTML changelog.html to point to the real sources on SF.
2769 - added missing LOG_THIS definition to gui/nogui.cc and gui/rfb.cc
2770 - added additional check for null pointer in debugger exit routine
2771 - added diskd to .bochsrc
2773 -------------------------------------------------------------------------
2774 Changes in version 1.2-pre1 (May 25, 2001):
2775 - major cleanup of .bochsrc
2776 - major cleanup of stderr output: prints bochs version information when
2777 starting, and at the end it tries to print the message that caused
2779 - two hard disk support (diskd). At present, you cannot have two
2780 hard drives and a cdrom at the same time, because there is only
2781 one IDE controller with two channels.
2782 - split hard disk support allows different partitions to be stored in
2783 different image files
2784 - two new GUI choices: term mode and RFB mode. Term is a text-only
2785 interface, and RFB creates a server that can be accessed using
2786 the AT&T VNC viewer.
2787 - now Bochs can simulate an SMP machine, if you configure with
2788 --enable-processors=N. Configuring more than one processor has
2789 a major performance impact, so the default is 1 processor.
2790 See SMP documentation for more details.
2791 - to make SMP work, bx_mem and bx_cpu have been replaced with
2792 bx_mem_array[] and bx_cpu_array[]. The cpus are referenced through
2793 the BX_CPU(n) macro and memories through the BX_MEM(n). Normal
2794 mode has one cpu and one memory, SMP mode has multiple cpu's and
2795 one memory, cosimulation mode has multiple cpus and multiple memories.
2796 - use --enable-cpu-level=6 to make Bochs claim to be a Pentium Pro.
2797 The only feature that requires CPU level 6 is apic support.
2798 - new logging system by Todd Fries, which has 4 levels of event
2799 severity (panic, error, info, debug). There are new .bochsrc
2800 options that control what action to take when a
2801 panic/error/info/debug event occurs.
2802 - now searches for .bochsrc, bochsrc, bochsrc.txt, and (on unix only)
2804 - use GNU readline library if --enable-debugger is on, as long as readline
2805 can be found on the machine
2806 - configure checks for existence strtoull and strtouq. if neither exists,
2807 Bochs uses its own implementation
2808 - applied patches from Cliff Hones <cliff@aonix.co.uk> to fix up the
2809 rombios. This includes many improvements, which you can list by
2810 doing "cvs log -r 1.6 bios/rombios.c" or looking at cvsweb.
2811 - added suggested geometries of larger disks to the documentation
2812 - this is the first release to have official binary packages for win32
2813 and Linux. There is a new "make rpm" in the top-level Makefile which
2814 will create an RPM of the current bochs directory. To use this,
2815 become root and type "configure; make rpm".
2816 - applied some FreeBSD patches from Maxim Sobolev (cdrom and serial).
2818 -------------------------------------------------------------------------
2819 Changes in version 1.1.2 (bugfix3, May 16, 2001):
2820 - updated Elpin VGA BIOS to version 2.40, and changed pointer in .bochsrc
2821 - fixed .conf.x86 script so that it uses c++ instead of egcs for C++ files
2822 - now Makefile targets that recurse into subdirectories use double colons,
2823 so that it will always recurse into subdirectories. Now a single make
2824 command should notice a modified source file in a subdir.
2825 - fixed bug in bx_panic. If BX_PANIC_IS_FATAL==0 and a (non-fatal) panic
2826 occurs, it used to call bx_atexit() and then return. It should never
2827 call bx_atexit, which starts to shut down the simulator, unless it's
2828 really going to quit!
2829 - support 2.88 MB floppy disks
2830 - since dataseghack is checked in as non-executable, invoke it with
2832 - double fault patch from Thomas Petazzoni <thomas.petazzoni@ifrance.com>,
2833 sourceforge patch #423726.
2834 - removed -fno-builtin from fpu makefiles
2835 - redefine u_char, u_short, etc. in order to not conflict with system
2836 definitions of these same types.
2837 - in cdrom.cc, remove the extern "C" { } structure around some of the
2838 header files. This is no longer necessary.
2839 - do not panic on hard disk command 0x1f2 (read sector count)
2841 - apply Todd Fries' reset patch
2842 - recognize most of the "Grey" insert/delete/home/end/etc. keys the
2843 same as keypad keys.
2844 - removed panic on "kbd_ctrl_to_kbd(): got value of 0x??"
2845 - implement mouse command 0xf6 (set defaults)
2846 - apply Suboner@aol.com's Xwindows timing patch from
2847 http://sourceforge.net/tracker/index.php?func=detail&aid=418730&group_id=12580&atid=312580
2848 - remove all patches from patches subdir which have already been applied.
2849 The remaining ones are under consideration but not applied.
2851 -------------------------------------------------------------------------
2852 Changes in version 1.1.1 (bugfix2, April 9, 2001):
2853 - in soundwin.cc, arg 3 should be typecast to LPWAVEFORMATEX
2854 - in fpu_entry.c, Bryce mistyped his own initials!
2855 - in configure.in and configure, define good defaults for VC++
2856 #define BX_64BIT_CONSTANTS_USE_LL 0
2857 #define inline __inline
2858 #define BX_NO_EMPTY_STRUCTS 1
2859 #define BX_NO_ATTRIBUTES 1
2860 #define BX_HAVE_HASH_MAP 0
2861 - in config.h.in, fixed typo in #error message
2863 -------------------------------------------------------------------------
2864 Changes in version 1.1 (bugfix1, April 6, 2001):
2866 (FIXED, patch #414360: update copyrights)
2867 update headers. Change copyright to 2001, replace config.h.in header with
2868 the standard mandrake header that every other file uses.
2870 (FIXED, patch #414356: inlines)
2871 make macro to replace inline and static/extern keywords. Then make
2872 define the macro appropriately based on configure.
2874 (FIXED: patch #414234: macos-no-strdup)
2875 --with-macos should force HAVE_STRDUP=0.
2877 (FIXED, patch #403027: Fix mouse bugs in Linux and BSD)
2878 Linux and BSD (maybe others) cause panic in mouse code.
2880 (FIXED, patch #413851: const64bit patch)
2881 VC++ does not allow "LL" after 64-bit constant.
2883 (FIXED, patch #413859: fabs symbol conflict)
2884 fpu code contains fabs, which conflicts with math library fabs.
2886 (FIXED, patch #403004: Implement aborts on a few SET FEATURE commands...)
2887 Implement aborts on a few SET FEATURE commands for ATA.
2889 (FIXED, patch #402991: Update to iodev/vga.cc to add 3c3h read support)
2890 Implement VGA enable register, at 0x3c3.
2892 (FIXED, patch #403027: Fix mouse bugs in Linux and BSD)
2893 Mouse panic in linux/BSD:
2894 KBD: io write 0x64: command = 0xD3(write mouse outb)
2896 (FIXED, patch #414229: panic-is-fatal)
2897 Allow user to decide if panic is fatal, or just a warning
2899 (FIXED, patch #414230: sun-cdrom)
2902 (FIXED, patch #413574: portable1)
2903 there are cases where a pointer is cast to a 32-bit int,
2904 then later cast to a pointer and dereferenced, which crashes any 64-bit
2907 (FIXED, patch #413574: portable1)
2908 some machines have no snprintf or strtoull. include a replacement function
2911 (FIXED, patch #413574: portable1)
2912 Some compilers don't allow "typedef struct { } foo;"
2914 (FIXED, patch #413574: portable1)
2915 Some people don't have hash_map.h, used in dbg_main.cc. Disable this code
2916 if hash_map.h not found.
2918 (FIXED, patch #413574: portable1)
2919 Some compilers can't handle labels at the end of a block, as in
2920 void main () { /*code*/ label: }
2922 (FIXED, patch #413574: portable1)
2923 Most compilers can't handle __attribute__. Use macro to define it away.
2925 (FIXED, patch #413574: portable1)
2926 if --enable-debugger, turn on --enable-disasm too.
2928 (FIXED, patch #413574: portable1)
2929 ome compilers can't handle any chars after an #endif
2931 (FIXED, patch #413574: portable1)
2932 wrong type arg1 of bx_dbg_watch and bx_dbg_unwatch. The code in
2933 lexer.l was calling it with integers (not booleans)
2935 (FIXED, patch #413574: portable1)
2936 in fpu code, "setcc" macro was implemented with braces inside parens,
2937 which some compilers don't understand.
2939 (FIXED, patch #413574: portable1)
2940 in fpu_entry.c, FPU_load_int32 was consistently called with arg1 of
2941 type (s32 *), but should be (u32 *)
2943 (FIXED, patch #413574: portable1)
2944 comment out sigcontext structure in fpu/stubs/asm/sigcontext.h because
2945 it conflicted with sigcontext of other machines. This struct was never
2946 used by bochs anyway.
2948 (FIXED, patch #414046: portable2)
2949 move definition of missing library functions into osdep.h and osdep.cc,
2950 include contents of macutils*.
2952 (FIXED, patch #414061: win32-rawcd)
2953 CDROM drive letter for WIN32 should not be hardcoded.
2955 (FIXED, patch #414060: win32-rawfloppy)
2956 Bypass fstat when opening WIN32 raw floppy disk.
2958 (FIXED, patch #414226: pit-panic)
2959 WinME install dies with panic:
2960 bochs: panic, pit: outp(43h): comm Bh, mode 00, bcd 00 unhandled
2961 I think I had a similar problem. All three timers should support modes
2962 0, 2, and 3. Other modes really aren't implemented.
