23 the name of your SCSI host adapter (the card inside your computer
24 that "speaks" the SCSI protocol, also called SCSI controller),
25 because you will be asked for it.
27 You also need to say Y here if you have a device which speaks
28 the SCSI protocol. Examples of this include the parallel port
29 version of the IOMEGA ZIP drive, USB storage devices, Fibre
30 Channel, and FireWire storage.

105 tristate "SCSI OnStream SC-x0 tape support"
108 The OnStream SC-x0 SCSI tape drives cannot be driven by the
109 standard st driver, but instead need this special osst driver and
110 use the /dev/osstX char device nodes (major 206). Via usb-storage,
111 you may be able to drive the USB-x0 and DI-x0 drives as well.
112 Note that there is also a second generation of OnStream
113 tape drives (ADR-x0) that supports the standard SCSI-2 commands for
114 tapes (QIC-157) and can be driven by the standard driver st.
115 For more information, you may have a look at the SCSI-HOWTO
116 <http://www.tldp.org/docs.html#howto> and
117 <file:Documentation/scsi/osst.txt> in the kernel source.
118 More info on the OnStream driver may be found on

144 This enables the usage of vendor specific SCSI commands. This is
145 required to support multisession CDs with old NEC/TOSHIBA cdrom
146 drives (and HP Writers). If you have such a drive and get the first
147 session only, try saying Y here; everybody else says N.
150 tristate "SCSI generic support"
153 If you want to use SCSI scanners, synthesizers or CD-writers or just
154 about anything having "SCSI" in its name other than hard disks,
155 CD-ROMs or tapes, say Y here. These won't be supported by the kernel
156 directly, so you need some additional software which knows how to
157 talk to these devices using the SCSI protocol:
159 For scanners, look at SANE (<http://www.sane-project.org/>). For CD
160 writer software look at Cdrtools
161 (<http://cdrecord.berlios.de/private/cdrecord.html>)
162 and for burning a "disk at once": CDRDAO
163 (<http://cdrdao.sourceforge.net/>). Cdparanoia is a high
164 quality digital reader of audio CDs (<http://www.xiph.org/paranoia/>).
165 For other devices, it's possible that you'll have to write the
166 driver software yourself. Please read the file
167 <file:Documentation/scsi/scsi-generic.txt> for more information.
169 To compile this driver as a module, choose M here and read
170 <file:Documentation/scsi/scsi.txt>. The module will be called sg.
175 tristate "SCSI media changer support"
178 This is a driver for SCSI media changers. Most common devices are
179 tape libraries and MOD/CDROM jukeboxes. *Real* jukeboxes, you
180 don't need this for those tiny 6-slot cdrom changers. Media
181 changers are listed as "Type: Medium Changer" in /proc/scsi/scsi.
182 If you have such hardware and want to use it with linux, say Y
183 here. Check <file:Documentation/scsi/scsi-changer.txt> for details.
185 If you want to compile this as a module ( = code which can be
186 inserted in and removed from the running kernel whenever you want),
187 say M here and read <file:Documentation/kbuild/modules.txt> and
188 <file:Documentation/scsi/scsi.txt>. The module will be called ch.o.
191 config SCSI_ENCLOSURE
192 tristate "SCSI Enclosure Support"
193 depends on SCSI && ENCLOSURE_SERVICES
195 Enclosures are devices sitting on or in SCSI backplanes that
196 manage devices. If you have a disk cage, the chances are that
197 it has an enclosure device. Selecting this option will just allow
198 certain enclosure conditions to be reported and is not required.
200 config SCSI_MULTI_LUN
201 bool "Probe all LUNs on each SCSI device"
204 Some devices support more than one LUN (Logical Unit Number) in order
205 to allow access to several media, e.g. CD jukebox, USB card reader,
206 mobile phone in mass storage mode. This option forces the kernel to
207 probe for all LUNs by default. This setting can be overriden by
208 max_luns boot/module parameter. Note that this option does not affect
209 devices conforming to SCSI-3 or higher as they can explicitely report
210 their number of LUNs. It is safe to say Y here unless you have one of
211 those rare devices which reacts in an unexpected way when probed for
214 config SCSI_CONSTANTS
215 bool "Verbose SCSI error reporting (kernel size +=12K)"
218 The error messages regarding your SCSI hardware will be easier to
219 understand if you say Y here; it will enlarge your kernel by about
220 12 KB. If in doubt, say Y.
223 bool "SCSI logging facility"
226 This turns on a logging facility that can be used to debug a number
227 of SCSI related problems.
229 If you say Y here, no logging output will appear by default, but you
230 can enable logging by saying Y to "/proc file system support" and
231 "Sysctl support" below and executing the command
233 echo <bitmask> > /proc/sys/dev/scsi/logging_level
235 where <bitmask> is a four byte value representing the logging type
236 and logging level for each type of logging selected.
238 There are a number of logging types and you can find them in the
239 source at <file:drivers/scsi/scsi_logging.h>. The logging levels
240 are also described in that file and they determine the verbosity of
241 the logging for each logging type.
243 If you say N here, it may be harder to track down some types of SCSI
244 problems. If you say Y here your kernel will be somewhat larger, but
245 there should be no noticeable performance impact as long as you have
248 config SCSI_SCAN_ASYNC
249 bool "Asynchronous SCSI scanning"
252 The SCSI subsystem can probe for devices while the rest of the
253 system continues booting, and even probe devices on different
254 busses in parallel, leading to a significant speed-up.
256 If you have built SCSI as modules, enabling this option can
257 be a problem as the devices may not have been found by the
258 time your system expects them to have been. You can load the
259 scsi_wait_scan module to ensure that all scans have completed.
260 If you build your SCSI drivers into the kernel, then everything
261 will work fine if you say Y here.
263 You can override this choice by specifying "scsi_mod.scan=sync"
264 or async on the kernel's command line.
266 config SCSI_WAIT_SCAN
267 tristate # No prompt here, this is an invisible symbol.
271 # scsi_wait_scan is a loadable module which waits until all the async scans are
272 # complete. The idea is to use it in initrd/ initramfs scripts. You modprobe
273 # it after all the modprobes of the root SCSI drivers and it will wait until
274 # they have all finished scanning their buses before allowing the boot to
275 # proceed. (This method is not applicable if targets boot independently in
276 # parallel with the initiator, or with transports with non-deterministic target
277 # discovery schemes, or if a transport driver does not support scsi_wait_scan.)
279 # This symbol is not exposed as a prompt because little is to be gained by
280 # disabling it, whereas people who accidentally switch it off may wonder why
281 # their mkinitrd gets into trouble.

359 The iSCSI Driver provides a host with the ability to access storage
360 through an IP network. The driver uses the iSCSI protocol to transport
361 SCSI requests and responses over a TCP/IP network between the host
362 (the "initiator") and "targets". Architecturally, the iSCSI driver
363 combines with the host's TCP/IP stack, network drivers, and Network

736 depends on (ISA || EISA || PCI) && SCSI && ISA_DMA_API
738 This driver supports all EATA/DMA-compliant SCSI host adapters. DPT
739 ISA and all EISA I/O addresses are probed looking for the "EATA"
740 signature. The addresses of all the PCI SCSI controllers reported
741 by the PCI subsystem are probed as well.
743 You want to read the start of <file:drivers/scsi/eata.c> and the

750 config SCSI_EATA_TAGGED_QUEUE
751 bool "enable tagged command queueing"
754 This is a feature of SCSI-2 which improves performance: the host
755 adapter can send several SCSI commands to a device's queue even if
756 previous commands haven't finished yet.
757 This is equivalent to the "eata=tc:y" boot option.
759 config SCSI_EATA_LINKED_COMMANDS
760 bool "enable elevator sorting"
763 This option enables elevator sorting for all probed SCSI disks and
764 CD-ROMs. It definitely reduces the average seek distance when doing
765 random seeks, but this does not necessarily result in a noticeable
766 performance improvement: your mileage may vary...
767 This is equivalent to the "eata=lc:y" boot option.
769 config SCSI_EATA_MAX_TAGS
770 int "maximum number of queued commands"
774 This specifies how many SCSI commands can be maximally queued for
775 each probed SCSI device. You should reduce the default value of 16
776 only if you have disks with buggy or limited tagged command support.
777 Minimum is 2 and maximum is 62. This value is also the window size
778 used by the elevator sorting option above. The effective value used
779 by the driver for each probed SCSI device is reported at boot time.
780 This is equivalent to the "eata=mq:8" boot option.

784 depends on (ISA || EISA || PCI) && SCSI && BROKEN
786 This driver supports all EATA-PIO protocol compliant SCSI Host
787 Adapters like the DPT PM2001 and the PM2012A. EATA-DMA compliant
788 host adapters could also use this driver but are discouraged from
789 doing so, since this driver only supports hard disks and lacks
790 numerous features. You might want to have a look at the SCSI-HOWTO,

801 This is support for Future Domain's 16-bit SCSI host adapters
802 (TMC-1660/1680, TMC-1650/1670, TMC-3260, TMC-1610M/MER/MEX) and
803 other adapters based on the Future Domain chipsets (Quantum
804 ISA-200S, ISA-250MG; Adaptec AHA-2920A; and at least one IBM board).
805 It is explained in section 3.7 of the SCSI-HOWTO, available from
806 <http://www.tldp.org/docs.html#howto>.
808 NOTE: Newer Adaptec AHA-2920C boards use the Adaptec AIC-7850 chip

820 This is support for Future Domain MCS 600/700 MCA SCSI adapters.
821 Some PS/2 computers are equipped with IBM Fast SCSI Adapter/A which
822 is identical to the MCS 700 and hence also supported by this driver.
823 This driver also supports the Reply SB16/SCSI card (the SCSI part).

857 tristate "Generic NCR5380/53c400 SCSI PIO support"
858 depends on ISA && SCSI
859 select SCSI_SPI_ATTRS
861 This is a driver for the old NCR 53c80 series of SCSI controllers
862 on boards using PIO. Most boards such as the Trantor T130 fit this
863 category, along with a large number of ISA 8bit controllers shipped
864 for free with SCSI scanners. If you have a PAS16, T128 or DMX3191
865 you should select the specific driver for that card rather than
866 generic 5380 support.
868 It is explained in section 3.8 of the SCSI-HOWTO, available from
869 <http://www.tldp.org/docs.html#howto>. If it doesn't work out

893 depends on SCSI_GENERIC_NCR5380
895 This enables certain optimizations for the NCR53c400 SCSI cards.
896 You might as well try it out. Note that this driver will only probe
897 for the Trantor T130B in its default configuration; you might have
898 to pass a command line option to the kernel at boot time if it does
899 not detect your card. See the file
900 <file:Documentation/scsi/g_NCR5380.txt> for details.
903 tristate "IBMMCA SCSI support"
904 depends on MCA && SCSI
906 This is support for the IBM SCSI adapter found in many of the PS/2
907 series computers. These machines have an MCA bus, so you need to
908 answer Y to "MCA support" as well and read
909 <file:Documentation/mca.txt>.
911 If the adapter isn't found during boot (a common problem for models
912 56, 57, 76, and 77) you'll need to use the 'ibmmcascsi=<pun>' kernel
913 option, where <pun> is the id of the SCSI subsystem (usually 7, but
914 if that doesn't work check your reference diskette). Owners of
915 model 95 with a LED-matrix-display can in addition activate some
916 activity info like under OS/2, but more informative, by setting
917 'ibmmcascsi=display' as an additional kernel parameter. Try "man
918 bootparam" or see the documentation of your boot loader about how to
919 pass options to the kernel.
921 To compile this driver as a module, choose M here: the
922 module will be called ibmmca.
924 config IBMMCA_SCSI_ORDER_STANDARD
925 bool "Standard SCSI-order"
926 depends on SCSI_IBMMCA
928 In the PC-world and in most modern SCSI-BIOS-setups, SCSI-hard disks
929 are assigned to the drive letters, starting with the lowest SCSI-id
930 (physical number -- pun) to be drive C:, as seen from DOS and
931 similar operating systems. When looking into papers describing the
932 ANSI-SCSI-standard, this assignment of drives appears to be wrong.
933 The SCSI-standard follows a hardware-hierarchy which says that id 7
934 has the highest priority and id 0 the lowest. Therefore, the host
935 adapters are still today everywhere placed as SCSI-id 7 by default.
936 In the SCSI-standard, the drive letters express the priority of the
937 disk. C: should be the hard disk, or a partition on it, with the
938 highest priority. This must therefore be the disk with the highest
939 SCSI-id (e.g. 6) and not the one with the lowest! IBM-BIOS kept the
940 original definition of the SCSI-standard as also industrial- and
941 process-control-machines, like VME-CPUs running under realtime-OSes
942 (e.g. LynxOS, OS9) do.
944 If you like to run Linux on your MCA-machine with the same
945 assignment of hard disks as seen from e.g. DOS or OS/2 on your
946 machine, which is in addition conformant to the SCSI-standard, you
947 must say Y here. This is also necessary for MCA-Linux users who want
948 to keep downward compatibility to older releases of the
949 IBM-MCA-SCSI-driver (older than driver-release 2.00 and older than
952 If you like to have the lowest SCSI-id assigned as drive C:, as
953 modern SCSI-BIOSes do, which does not conform to the standard, but
954 is widespread and common in the PC-world of today, you must say N
955 here. If unsure, say Y.
957 config IBMMCA_SCSI_DEV_RESET
958 bool "Reset SCSI-devices at boottime"
959 depends on SCSI_IBMMCA
961 By default, SCSI-devices are reset when the machine is powered on.
962 However, some devices exist, like special-control-devices,
963 SCSI-CNC-machines, SCSI-printer or scanners of older type, that do
964 not reset when switched on. If you say Y here, each device connected
965 to your SCSI-bus will be issued a reset-command after it has been
966 probed, while the kernel is booting. This may cause problems with
967 more modern devices, like hard disks, which do not appreciate these
968 reset commands, and can cause your system to hang. So say Y only if
969 you know that one of your older devices needs it; N is the safe

1125 Some parallel ports are known to have excessive delays between
1126 changing the parallel port control register and good data being
1127 available on the parallel port data/status register. This option
1128 forces a small delay (1.0 usec to be exact) after changing the
1129 control register to let things settle out. Enabling this option may
1130 result in a big drop in performance but some very old parallel ports

1205 PCI-SCSI controllers. It also supports the subset of LSI53C10XX
1206 Ultra-160 controllers that are based on the SYM53C8XX SCRIPTS
1207 language. It does not support LSI53C10XX Ultra-320 PCI-X SCSI

1219 capable (875A, 895A, 896, 1010-33, 1010-66, 1000).
1221 When set to 0, the driver will program the chip to only perform
1222 32-bit DMA. When set to 1, the chip will be able to perform DMA
1223 to addresses up to 1TB. When set to 2, the driver supports the
1224 full 64-bit DMA address range, but can only address 16 segments
1225 of 4 GB each. This limits the total addressable range to 64 GB.
1227 Most machines with less than 4GB of memory should use a setting
1228 of 0 for best performance. If your machine has 4GB of memory
1229 or more, you should set this option to 1 (the default).
1231 The still experimental value 2 (64 bit DMA addressing with 16
1232 x 4GB segments limitation) can be used on systems that require

1300 C110, J200, J210 and some D, K & R-class machines. It's also
1301 used on the add-in Bluefish, Barracuda & Shrike SCSI cards.

1304 config SCSI_NCR_Q720
1305 tristate "NCR Quad 720 MCA SCSI support"
1306 depends on MCA && SCSI
1307 select SCSI_SPI_ATTRS
1309 This is a driver for the MicroChannel Quad 720 card produced by
1310 NCR and commonly used in 345x/35xx/4100 class machines. It always
1311 tries to negotiate sync and uses tag command queueing.
1313 Unless you have an NCR manufactured machine, the chances are that
1314 you do not have this SCSI card, so say N.
1316 config SCSI_NCR53C8XX_DEFAULT_TAGS
1317 int "default tagged command queue depth"
1318 depends on SCSI_ZALON || SCSI_NCR_Q720
1321 "Tagged command queuing" is a feature of SCSI-2 which improves
1322 performance: the host adapter can send several SCSI commands to a
1323 device's queue even if previous commands haven't finished yet.
1324 Because the device is intelligent, it can optimize its operations
1325 (like head positioning) based on its own request queue. Some SCSI
1326 devices don't implement this properly; if you want to disable this
1327 feature, enter 0 or 1 here (it doesn't matter which).
1329 The default value is 8 and should be supported by most hard disks.
1330 This value can be overridden from the boot command line using the
1331 'tags' option as follows (example):
1332 'ncr53c8xx=tags:4/t2t3q16/t0u2q10' will set default queue depth to
1333 4, set queue depth to 16 for target 2 and target 3 on controller 0
1334 and set queue depth to 10 for target 0 / lun 2 on controller 1.
1336 The normal answer therefore is to go with the default 8 and to use
1337 a boot command line option for devices that need to use a different
1338 command queue depth.
1340 There is no safe option other than using good SCSI devices.
1342 config SCSI_NCR53C8XX_MAX_TAGS
1343 int "maximum number of queued commands"
1344 depends on SCSI_ZALON || SCSI_NCR_Q720
1347 This option allows you to specify the maximum number of commands
1348 that can be queued to any device, when tagged command queuing is
1349 possible. The default value is 32. Minimum is 2, maximum is 64.
1350 Modern hard disks are able to support 64 tags and even more, but
1351 do not seem to be faster when more than 32 tags are being used.
1353 So, the normal answer here is to go with the default value 32 unless
1354 you are using very large hard disks with large cache (>= 1 MB) that
1355 are able to take advantage of more than 32 tagged commands.
1357 There is no safe option and the default answer is recommended.
1359 config SCSI_NCR53C8XX_SYNC
1360 int "synchronous transfers frequency in MHz"
1361 depends on SCSI_ZALON || SCSI_NCR_Q720
1364 The SCSI Parallel Interface-2 Standard defines 5 classes of transfer
1365 rates: FAST-5, FAST-10, FAST-20, FAST-40 and FAST-80. The numbers
1366 are respectively the maximum data transfer rates in mega-transfers
1367 per second for each class. For example, a FAST-20 Wide 16 device is
1368 able to transfer data at 20 million 16 bit packets per second for a
1369 total rate of 40 MB/s.
1371 You may specify 0 if you want to only use asynchronous data
1372 transfers. This is the safest and slowest option. Otherwise, specify
1373 a value between 5 and 80, depending on the capability of your SCSI
1374 controller. The higher the number, the faster the data transfer.
1375 Note that 80 should normally be ok since the driver decreases the
1376 value automatically according to the controller's capabilities.
1378 Your answer to this question is ignored for controllers with NVRAM,
1379 since the driver will get this information from the user set-up. It
1380 also can be overridden using a boot setup option, as follows
1381 (example): 'ncr53c8xx=sync:12' will allow the driver to negotiate
1382 for FAST-20 synchronous data transfer (20 mega-transfers per
1385 The normal answer therefore is not to go with the default but to
1386 select the maximum value 80 allowing the driver to use the maximum
1387 value supported by each controller. If this causes problems with
1388 your SCSI devices, you should come back and decrease the value.
1390 There is no safe option other than using good cabling, right
1391 terminations and SCSI conformant devices.
1393 config SCSI_NCR53C8XX_NO_DISCONNECT
1394 bool "not allow targets to disconnect"
1395 depends on (SCSI_ZALON || SCSI_NCR_Q720) && SCSI_NCR53C8XX_DEFAULT_TAGS=0
1397 This option is only provided for safety if you suspect some SCSI
1398 device of yours to not support properly the target-disconnect
1399 feature. In that case, you would say Y here. In general however, to
1400 not allow targets to disconnect is not reasonable if there is more
1401 than 1 device on a SCSI bus. The normal answer therefore is N.

1593 each probed SCSI device. You should reduce the default value of 8
1594 only if you have disks with buggy or limited tagged command support.
1595 Minimum is 2 and maximum is 14. This value is also the window size
1596 used by the elevator sorting option above. The effective value used

1636 RAM as storage (i.e. it is a ramdisk). To save space when multiple
1637 dummy disks are simulated, they share the same kernel RAM for
1638 their storage. See <http://sg.danny.cz/sg/sdebug26.html> for more

1662 operation at up to 10 MB/s. On machines where the SCSI bus
1663 controlled by the MESH can have external devices connected, it is
1664 usually rated at 5 MB/s. 5 is a safe value here unless you know the
