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

101 The OnStream SC-x0 SCSI tape drives cannot be driven by the
102 standard st driver, but instead need this special osst driver and
103 use the /dev/osstX char device nodes (major 206). Via usb-storage
104 and ide-scsi, you may be able to drive the USB-x0 and DI-x0 drives
105 as well. Note that there is also a second generation of OnStream
106 tape drives (ADR-x0) that supports the standard SCSI-2 commands for
107 tapes (QIC-157) and can be driven by the standard driver st.
108 For more information, you may have a look at the SCSI-HOWTO

145 If you want to use SCSI scanners, synthesizers or CD-writers or just
146 about anything having "SCSI" in its name other than hard disks,
147 CD-ROMs or tapes, say Y here. These won't be supported by the kernel
148 directly, so you need some additional software which knows how to
149 talk to these devices using the SCSI protocol:
151 For scanners, look at SANE (<http://www.mostang.com/sane/>). For CD
152 writer software look at Cdrtools
153 (<http://www.fokus.gmd.de/research/cc/glone/employees/joerg.schilling/private/cdrecord.html>)
154 and for burning a "disk at once": CDRDAO
155 (<http://cdrdao.sourceforge.net/>). Cdparanoia is a high
156 quality digital reader of audio CDs (<http://www.xiph.org/paranoia/>).
157 For other devices, it's possible that you'll have to write the
158 driver software yourself. Please read the file

172 don't need this for those tiny 6-slot cdrom changers. Media
173 changers are listed as "Type: Medium Changer" in /proc/scsi/scsi.

188 bool "Probe all LUNs on each SCSI device"
191 If you have a SCSI device that supports more than one LUN (Logical
192 Unit Number), e.g. a CD jukebox, and only one LUN is detected, you
193 can say Y here to force the SCSI driver to probe for multiple LUNs.
194 A SCSI device with multiple LUNs acts logically like multiple SCSI
195 devices. The vast majority of SCSI devices have only one LUN, and
196 so most people can say N here. The max_luns boot/module parameter
197 allows to override this setting.
199 config SCSI_CONSTANTS
200 bool "Verbose SCSI error reporting (kernel size +=12K)"
203 The error messages regarding your SCSI hardware will be easier to
204 understand if you say Y here; it will enlarge your kernel by about
205 12 KB. If in doubt, say Y.
208 bool "SCSI logging facility"
211 This turns on a logging facility that can be used to debug a number
212 of SCSI related problems.
214 If you say Y here, no logging output will appear by default, but you
215 can enable logging by saying Y to "/proc file system support" and
216 "Sysctl support" below and executing the command
218 echo "scsi log token [level]" > /proc/scsi/scsi
220 at boot time after the /proc file system has been mounted.
222 There are a number of things that can be used for 'token' (you can
223 find them in the source: <file:drivers/scsi/scsi.c>), and this
224 allows you to select the types of information you want, and the
225 level allows you to select the level of verbosity.
227 If you say N here, it may be harder to track down some types of SCSI
228 problems. If you say Y here your kernel will be somewhat larger, but
229 there should be no noticeable performance impact as long as you have
232 config SCSI_SCAN_ASYNC
233 bool "Asynchronous SCSI scanning"
236 The SCSI subsystem can probe for devices while the rest of the
237 system continues booting, and even probe devices on different
238 busses in parallel, leading to a significant speed-up.
240 If you have built SCSI as modules, enabling this option can
241 be a problem as the devices may not have been found by the
242 time your system expects them to have been. You can load the
243 scsi_wait_scan module to ensure that all scans have completed.
244 If you build your SCSI drivers into the kernel, then everything
245 will work fine if you say Y here.
247 You can override this choice by specifying "scsi_mod.scan=sync"
248 or async on the kernel's command line.

745 This is a driver for the old NCR 53c80 series of SCSI controllers
746 on boards using PIO. Most boards such as the Trantor T130 fit this
747 category, along with a large number of ISA 8bit controllers shipped
748 for free with SCSI scanners. If you have a PAS16, T128 or DMX3191
749 you should select the specific driver for that card rather than
750 generic 5380 support.
752 It is explained in section 3.8 of the SCSI-HOWTO, available from

779 This enables certain optimizations for the NCR53c400 SCSI cards.
780 You might as well try it out. Note that this driver will only probe
781 for the Trantor T130B in its default configuration; you might have
782 to pass a command line option to the kernel at boot time if it does
783 not detect your card. See the file

787 tristate "IBMMCA SCSI support"
788 depends on MCA && SCSI
790 This is support for the IBM SCSI adapter found in many of the PS/2
791 series computers. These machines have an MCA bus, so you need to
792 answer Y to "MCA support" as well and read
793 <file:Documentation/mca.txt>.
795 If the adapter isn't found during boot (a common problem for models
796 56, 57, 76, and 77) you'll need to use the 'ibmmcascsi=<pun>' kernel
797 option, where <pun> is the id of the SCSI subsystem (usually 7, but
798 if that doesn't work check your reference diskette). Owners of
799 model 95 with a LED-matrix-display can in addition activate some
800 activity info like under OS/2, but more informative, by setting
801 'ibmmcascsi=display' as an additional kernel parameter. Try "man
802 bootparam" or see the documentation of your boot loader about how to
803 pass options to the kernel.

808 config IBMMCA_SCSI_ORDER_STANDARD
809 bool "Standard SCSI-order"
810 depends on SCSI_IBMMCA
812 In the PC-world and in most modern SCSI-BIOS-setups, SCSI-hard disks
813 are assigned to the drive letters, starting with the lowest SCSI-id
814 (physical number -- pun) to be drive C:, as seen from DOS and
815 similar operating systems. When looking into papers describing the
816 ANSI-SCSI-standard, this assignment of drives appears to be wrong.
817 The SCSI-standard follows a hardware-hierarchy which says that id 7
818 has the highest priority and id 0 the lowest. Therefore, the host
819 adapters are still today everywhere placed as SCSI-id 7 by default.
820 In the SCSI-standard, the drive letters express the priority of the
821 disk. C: should be the hard disk, or a partition on it, with the
822 highest priority. This must therefore be the disk with the highest
823 SCSI-id (e.g. 6) and not the one with the lowest! IBM-BIOS kept the
824 original definition of the SCSI-standard as also industrial- and
825 process-control-machines, like VME-CPUs running under realtime-OSes
826 (e.g. LynxOS, OS9) do.
828 If you like to run Linux on your MCA-machine with the same
829 assignment of hard disks as seen from e.g. DOS or OS/2 on your
830 machine, which is in addition conformant to the SCSI-standard, you
831 must say Y here. This is also necessary for MCA-Linux users who want
832 to keep downward compatibility to older releases of the
833 IBM-MCA-SCSI-driver (older than driver-release 2.00 and older than
836 If you like to have the lowest SCSI-id assigned as drive C:, as
837 modern SCSI-BIOSes do, which does not conform to the standard, but
838 is widespread and common in the PC-world of today, you must say N
839 here. If unsure, say Y.
841 config IBMMCA_SCSI_DEV_RESET
842 bool "Reset SCSI-devices at boottime"

845 By default, SCSI-devices are reset when the machine is powered on.
846 However, some devices exist, like special-control-devices,
847 SCSI-CNC-machines, SCSI-printer or scanners of older type, that do
848 not reset when switched on. If you say Y here, each device connected
849 to your SCSI-bus will be issued a reset-command after it has been
850 probed, while the kernel is booting. This may cause problems with
851 more modern devices, like hard disks, which do not appreciate these
852 reset commands, and can cause your system to hang. So say Y only if
853 you know that one of your older devices needs it; N is the safe

990 Some parallel ports are known to have excessive delays between

1084 capable (875A, 895A, 896, 1010-33, 1010-66, 1000).
1086 When set to 0, the driver will program the chip to only perform
1087 32-bit DMA. When set to 1, the chip will be able to perform DMA
1088 to addresses up to 1TB. When set to 2, the driver supports the
1089 full 64-bit DMA address range, but can only address 16 segments
1090 of 4 GB each. This limits the total addressable range to 64 GB.
1092 Most machines with less than 4GB of memory should use a setting
1093 of 0 for best performance. If your machine has 4GB of memory
1094 or more, you should set this option to 1 (the default).
1096 The still experimental value 2 (64 bit DMA addressing with 16
1097 x 4GB segments limitation) can be used on systems that require
1098 PCI address bits past bit 39 to be set for the addressing of

1174 This is a driver for the MicroChannel Quad 720 card produced by
1175 NCR and commonly used in 345x/35xx/4100 class machines. It always
1176 tries to negotiate sync and uses tag command queueing.
1178 Unless you have an NCR manufactured machine, the chances are that

1181 config SCSI_NCR53C8XX_DEFAULT_TAGS
1182 int "default tagged command queue depth"
1183 depends on SCSI_ZALON || SCSI_NCR_Q720
1186 "Tagged command queuing" is a feature of SCSI-2 which improves
1187 performance: the host adapter can send several SCSI commands to a
1188 device's queue even if previous commands haven't finished yet.
1189 Because the device is intelligent, it can optimize its operations
1190 (like head positioning) based on its own request queue. Some SCSI
1191 devices don't implement this properly; if you want to disable this
1192 feature, enter 0 or 1 here (it doesn't matter which).
1194 The default value is 8 and should be supported by most hard disks.
1195 This value can be overridden from the boot command line using the
1196 'tags' option as follows (example):
1197 'ncr53c8xx=tags:4/t2t3q16/t0u2q10' will set default queue depth to
1198 4, set queue depth to 16 for target 2 and target 3 on controller 0
1199 and set queue depth to 10 for target 0 / lun 2 on controller 1.
1201 The normal answer therefore is to go with the default 8 and to use
1202 a boot command line option for devices that need to use a different
1203 command queue depth.
1205 There is no safe option other than using good SCSI devices.
1207 config SCSI_NCR53C8XX_MAX_TAGS
1208 int "maximum number of queued commands"
1209 depends on SCSI_ZALON || SCSI_NCR_Q720
1212 This option allows you to specify the maximum number of commands
1213 that can be queued to any device, when tagged command queuing is
1214 possible. The default value is 32. Minimum is 2, maximum is 64.
1215 Modern hard disks are able to support 64 tags and even more, but
1216 do not seem to be faster when more than 32 tags are being used.
1218 So, the normal answer here is to go with the default value 32 unless
1219 you are using very large hard disks with large cache (>= 1 MB) that
1220 are able to take advantage of more than 32 tagged commands.
1222 There is no safe option and the default answer is recommended.
1224 config SCSI_NCR53C8XX_SYNC
1225 int "synchronous transfers frequency in MHz"
1226 depends on SCSI_ZALON || SCSI_NCR_Q720
1229 The SCSI Parallel Interface-2 Standard defines 5 classes of transfer
1230 rates: FAST-5, FAST-10, FAST-20, FAST-40 and FAST-80. The numbers
1231 are respectively the maximum data transfer rates in mega-transfers
1232 per second for each class. For example, a FAST-20 Wide 16 device is
1233 able to transfer data at 20 million 16 bit packets per second for a
1234 total rate of 40 MB/s.
1236 You may specify 0 if you want to only use asynchronous data
1237 transfers. This is the safest and slowest option. Otherwise, specify
1238 a value between 5 and 80, depending on the capability of your SCSI
1239 controller. The higher the number, the faster the data transfer.
1240 Note that 80 should normally be ok since the driver decreases the
1241 value automatically according to the controller's capabilities.
1243 Your answer to this question is ignored for controllers with NVRAM,
1244 since the driver will get this information from the user set-up. It
1245 also can be overridden using a boot setup option, as follows
1246 (example): 'ncr53c8xx=sync:12' will allow the driver to negotiate
1247 for FAST-20 synchronous data transfer (20 mega-transfers per
1250 The normal answer therefore is not to go with the default but to
1251 select the maximum value 80 allowing the driver to use the maximum
1252 value supported by each controller. If this causes problems with
1253 your SCSI devices, you should come back and decrease the value.
1255 There is no safe option other than using good cabling, right
1256 terminations and SCSI conformant devices.

1259 bool "not allow targets to disconnect"
1260 depends on (SCSI_ZALON || SCSI_NCR_Q720) && SCSI_NCR53C8XX_DEFAULT_TAGS=0
1262 This option is only provided for safety if you suspect some SCSI
1263 device of yours to not support properly the target-disconnect
1264 feature. In that case, you would say Y here. In general however, to
1265 not allow targets to disconnect is not reasonable if there is more

1369 the sym53c416 is configured first using some sort of PnP
1370 configuration program (e.g. isapnp) or by a PnP aware BIOS. If you
1371 are using isapnp then you need to compile this driver as a module
1372 and then load it using insmod after isapnp has run. The parameters
1373 of the configured card(s) should be passed to the driver. The format

1446 config SCSI_U14_34F_TAGGED_QUEUE
1447 bool "enable tagged command queueing"
1448 depends on SCSI_U14_34F
1450 This is a feature of SCSI-2 which improves performance: the host
1451 adapter can send several SCSI commands to a device's queue even if
1452 previous commands haven't finished yet.
1453 This is equivalent to the "u14-34f=tc:y" boot option.
1455 config SCSI_U14_34F_LINKED_COMMANDS
1456 bool "enable elevator sorting"
1457 depends on SCSI_U14_34F
1459 This option enables elevator sorting for all probed SCSI disks and
1460 CD-ROMs. It definitely reduces the average seek distance when doing
1461 random seeks, but this does not necessarily result in a noticeable
1462 performance improvement: your mileage may vary...
1463 This is equivalent to the "u14-34f=lc:y" boot option.
1465 config SCSI_U14_34F_MAX_TAGS
1466 int "maximum number of queued commands"
1467 depends on SCSI_U14_34F
1470 This specifies how many SCSI commands can be maximally queued for
1471 each probed SCSI device. You should reduce the default value of 8
1472 only if you have disks with buggy or limited tagged command support.
1473 Minimum is 2 and maximum is 14. This value is also the window size
1474 used by the elevator sorting option above. The effective value used
1475 by the driver for each probed SCSI device is reported at boot time.
1476 This is equivalent to the "u14-34f=mq:8" boot option.

1507 tristate "SCSI debugging host simulator"
1510 This is a host adapter simulator that can simulate multiple hosts
1511 each with multiple dummy SCSI devices (disks). It defaults to one
1512 host adapter with one dummy SCSI disk. Each dummy disk uses kernel
1513 RAM as storage (i.e. it is a ramdisk). To save space when multiple
1514 dummy disks are simulated, they share the same kernel RAM for
1515 their storage. See <http://www.torque.net/sg/sdebug.html> for more
1516 information. This driver is primarily of use to those testing the
1517 SCSI and block subsystems. If unsure, say N.

1533 depends on SCSI_MESH
1536 On Power Macintoshes (and clones) where the MESH SCSI bus adaptor
1537 drives a bus which is entirely internal to the machine (such as the
1538 7500, 7600, 8500, etc.), the MESH is capable of synchronous
1539 operation at up to 10 MB/s. On machines where the SCSI bus
1540 controlled by the MESH can have external devices connected, it is
1541 usually rated at 5 MB/s. 5 is a safe value here unless you know the
1542 MESH SCSI bus is internal only; in that case you can say 10. Say 0
1543 to disable synchronous operation.

1552 depends on PPC32 && PPC_PMAC && SCSI
1554 On Power Macintoshes (and clones) with two SCSI buses, the external
1555 SCSI bus is usually controlled by a 53C94 SCSI bus adaptor. Older
1556 machines which only have one SCSI bus, such as the 7200, also use
1557 the 53C94. Say Y to include support for the 53C94.
