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
119 <http://sourceforge.net/projects/osst/>
120 Please also have a look at the standard st docu, as most of it
121 applies to osst as well.

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.

344 SCSI requests and responses over a TCP/IP network between the host
345 (the "initiator") and "targets". Architecturally, the iSCSI driver
346 combines with the host's TCP/IP stack, network drivers, and Network

727 module will be called eata.
729 config SCSI_EATA_TAGGED_QUEUE
730 bool "enable tagged command queueing"
733 This is a feature of SCSI-2 which improves performance: the host
734 adapter can send several SCSI commands to a device's queue even if
735 previous commands haven't finished yet.
736 This is equivalent to the "eata=tc:y" boot option.
738 config SCSI_EATA_LINKED_COMMANDS
739 bool "enable elevator sorting"
742 This option enables elevator sorting for all probed SCSI disks and
743 CD-ROMs. It definitely reduces the average seek distance when doing
744 random seeks, but this does not necessarily result in a noticeable
745 performance improvement: your mileage may vary...
746 This is equivalent to the "eata=lc:y" boot option.
748 config SCSI_EATA_MAX_TAGS
749 int "maximum number of queued commands"
753 This specifies how many SCSI commands can be maximally queued for
754 each probed SCSI device. You should reduce the default value of 16
755 only if you have disks with buggy or limited tagged command support.
756 Minimum is 2 and maximum is 62. This value is also the window size
757 used by the elevator sorting option above. The effective value used
758 by the driver for each probed SCSI device is reported at boot time.
759 This is equivalent to the "eata=mq:8" boot option.
762 tristate "EATA-PIO (old DPT PM2001, PM2012A) support"
763 depends on (ISA || EISA || PCI) && SCSI && BROKEN
765 This driver supports all EATA-PIO protocol compliant SCSI Host
766 Adapters like the DPT PM2001 and the PM2012A. EATA-DMA compliant
767 host adapters could also use this driver but are discouraged from
768 doing so, since this driver only supports hard disks and lacks
769 numerous features. You might want to have a look at the SCSI-HOWTO,

782 other adapters based on the Future Domain chipsets (Quantum
783 ISA-200S, ISA-250MG; Adaptec AHA-2920A; and at least one IBM board).
784 It is explained in section 3.7 of the SCSI-HOWTO, available from
785 <http://www.tldp.org/docs.html#howto>.
787 NOTE: Newer Adaptec AHA-2920C boards use the Adaptec AIC-7850 chip
788 and should use the aic7xxx driver ("Adaptec AIC7xxx chipset SCSI
789 controller support"). This Future Domain driver works with the older
790 Adaptec AHA-2920A boards with a Future Domain chip on them.

823 This is a driver for the old NCR 53c80 series of SCSI controllers
824 on boards using PIO. Most boards such as the Trantor T130 fit this
825 category, along with a large number of ISA 8bit controllers shipped
826 for free with SCSI scanners. If you have a PAS16, T128 or DMX3191
827 you should select the specific driver for that card rather than
828 generic 5380 support.

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

1001 EPP (Enhanced Parallel Port) is a standard for parallel ports which
1002 allows them to act as expansion buses that can handle up to 64
1005 Some parallel port chipsets are slower than their motherboard, and
1006 so we have to control the state of the chipset's FIFO queue every
1007 now and then to avoid data loss. This will be done if you say Y
1010 Generally, saying Y is the safe option and slows things down a bit.
1012 config SCSI_IZIP_SLOW_CTR
1013 bool "ppa/imm option - Assume slow parport control register"
1014 depends on SCSI_PPA || SCSI_IMM
1016 Some parallel ports are known to have excessive delays between
1017 changing the parallel port control register and good data being
1018 available on the parallel port data/status register. This option
1019 forces a small delay (1.0 usec to be exact) after changing the
1020 control register to let things settle out. Enabling this option may
1021 result in a big drop in performance but some very old parallel ports
1022 (found in 386 vintage machines) will not work properly.

1096 PCI-SCSI controllers. It also supports the subset of LSI53C10XX
1097 Ultra-160 controllers that are based on the SYM53C8XX SCRIPTS
1098 language. It does not support LSI53C10XX Ultra-320 PCI-X SCSI

1105 int "DMA addressing mode"

1109 This option only applies to PCI-SCSI chips that are PCI DAC
1110 capable (875A, 895A, 896, 1010-33, 1010-66, 1000).
1112 When set to 0, the driver will program the chip to only perform
1113 32-bit DMA. When set to 1, the chip will be able to perform DMA
1114 to addresses up to 1TB. When set to 2, the driver supports the
1115 full 64-bit DMA address range, but can only address 16 segments
1116 of 4 GB each. This limits the total addressable range to 64 GB.
1118 Most machines with less than 4GB of memory should use a setting
1119 of 0 for best performance. If your machine has 4GB of memory
1120 or more, you should set this option to 1 (the default).
1122 The still experimental value 2 (64 bit DMA addressing with 16
1123 x 4GB segments limitation) can be used on systems that require
1124 PCI address bits past bit 39 to be set for the addressing of

1132 This is the default value of the command queue depth the
1133 driver will announce to the generic SCSI layer for devices
1134 that support tagged command queueing. This value can be changed
1135 from the boot command line. This is a soft limit that cannot
1136 exceed CONFIG_SCSI_SYM53C8XX_MAX_TAGS.
1138 config SCSI_SYM53C8XX_MAX_TAGS

1143 This option allows you to specify the maximum number of commands
1144 that can be queued to any device, when tagged command queuing is
1145 possible. The driver supports up to 256 queued commands per device.
1146 This value is used as a compiled-in hard limit.

1197 depends on MCA && SCSI
1198 select SCSI_SPI_ATTRS
1200 This is a driver for the MicroChannel Quad 720 card produced by
1201 NCR and commonly used in 345x/35xx/4100 class machines. It always
1202 tries to negotiate sync and uses tag command queueing.
1204 Unless you have an NCR manufactured machine, the chances are that
1205 you do not have this SCSI card, so say N.
1207 config SCSI_NCR53C8XX_DEFAULT_TAGS
1208 int "default tagged command queue depth"
1209 depends on SCSI_ZALON || SCSI_NCR_Q720
1212 "Tagged command queuing" is a feature of SCSI-2 which improves
1213 performance: the host adapter can send several SCSI commands to a
1214 device's queue even if previous commands haven't finished yet.
1215 Because the device is intelligent, it can optimize its operations
1216 (like head positioning) based on its own request queue. Some SCSI
1217 devices don't implement this properly; if you want to disable this
1218 feature, enter 0 or 1 here (it doesn't matter which).
1220 The default value is 8 and should be supported by most hard disks.
1221 This value can be overridden from the boot command line using the
1222 'tags' option as follows (example):
1223 'ncr53c8xx=tags:4/t2t3q16/t0u2q10' will set default queue depth to
1224 4, set queue depth to 16 for target 2 and target 3 on controller 0
1225 and set queue depth to 10 for target 0 / lun 2 on controller 1.
1227 The normal answer therefore is to go with the default 8 and to use
1228 a boot command line option for devices that need to use a different
1229 command queue depth.
1231 There is no safe option other than using good SCSI devices.
1233 config SCSI_NCR53C8XX_MAX_TAGS
1234 int "maximum number of queued commands"
1235 depends on SCSI_ZALON || SCSI_NCR_Q720
1238 This option allows you to specify the maximum number of commands
1239 that can be queued to any device, when tagged command queuing is
1240 possible. The default value is 32. Minimum is 2, maximum is 64.
1241 Modern hard disks are able to support 64 tags and even more, but
1242 do not seem to be faster when more than 32 tags are being used.
1244 So, the normal answer here is to go with the default value 32 unless
1245 you are using very large hard disks with large cache (>= 1 MB) that
1246 are able to take advantage of more than 32 tagged commands.
1248 There is no safe option and the default answer is recommended.
1250 config SCSI_NCR53C8XX_SYNC
1251 int "synchronous transfers frequency in MHz"
1252 depends on SCSI_ZALON || SCSI_NCR_Q720
1255 The SCSI Parallel Interface-2 Standard defines 5 classes of transfer
1256 rates: FAST-5, FAST-10, FAST-20, FAST-40 and FAST-80. The numbers
1257 are respectively the maximum data transfer rates in mega-transfers
1258 per second for each class. For example, a FAST-20 Wide 16 device is
1259 able to transfer data at 20 million 16 bit packets per second for a
1260 total rate of 40 MB/s.
1262 You may specify 0 if you want to only use asynchronous data
1263 transfers. This is the safest and slowest option. Otherwise, specify
1264 a value between 5 and 80, depending on the capability of your SCSI
1265 controller. The higher the number, the faster the data transfer.
1266 Note that 80 should normally be ok since the driver decreases the
1267 value automatically according to the controller's capabilities.
1269 Your answer to this question is ignored for controllers with NVRAM,
1270 since the driver will get this information from the user set-up. It
1271 also can be overridden using a boot setup option, as follows
1272 (example): 'ncr53c8xx=sync:12' will allow the driver to negotiate
1273 for FAST-20 synchronous data transfer (20 mega-transfers per
1276 The normal answer therefore is not to go with the default but to
1277 select the maximum value 80 allowing the driver to use the maximum
1278 value supported by each controller. If this causes problems with
1279 your SCSI devices, you should come back and decrease the value.
1281 There is no safe option other than using good cabling, right
1282 terminations and SCSI conformant devices.
1284 config SCSI_NCR53C8XX_NO_DISCONNECT
1285 bool "not allow targets to disconnect"
1286 depends on (SCSI_ZALON || SCSI_NCR_Q720) && SCSI_NCR53C8XX_DEFAULT_TAGS=0
1288 This option is only provided for safety if you suspect some SCSI
1289 device of yours to not support properly the target-disconnect
1290 feature. In that case, you would say Y here. In general however, to
1291 not allow targets to disconnect is not reasonable if there is more
1292 than 1 device on a SCSI bus. The normal answer therefore is N.

1381 This is support for the sym53c416 SCSI host adapter, the SCSI
1382 adapter that comes with some HP scanners. This driver requires that
1383 the sym53c416 is configured first using some sort of PnP
1384 configuration program (e.g. isapnp) or by a PnP aware BIOS. If you
1385 are using isapnp then you need to compile this driver as a module
1386 and then load it using insmod after isapnp has run. The parameters
1387 of the configured card(s) should be passed to the driver. The format

1447 This is support for the UltraStor 14F and 34F SCSI-2 host adapters.
1448 The source at <file:drivers/scsi/u14-34f.c> contains some
1449 information about this hardware. If the driver doesn't work out of

1458 module will be called u14-34f.
1460 config SCSI_U14_34F_TAGGED_QUEUE
1461 bool "enable tagged command queueing"
1462 depends on SCSI_U14_34F
1464 This is a feature of SCSI-2 which improves performance: the host
1465 adapter can send several SCSI commands to a device's queue even if
1466 previous commands haven't finished yet.
1467 This is equivalent to the "u14-34f=tc:y" boot option.
1469 config SCSI_U14_34F_LINKED_COMMANDS
1470 bool "enable elevator sorting"
1471 depends on SCSI_U14_34F
1473 This option enables elevator sorting for all probed SCSI disks and
1474 CD-ROMs. It definitely reduces the average seek distance when doing
1475 random seeks, but this does not necessarily result in a noticeable
1476 performance improvement: your mileage may vary...
1477 This is equivalent to the "u14-34f=lc:y" boot option.
1479 config SCSI_U14_34F_MAX_TAGS
1480 int "maximum number of queued commands"
1481 depends on SCSI_U14_34F
1484 This specifies how many SCSI commands can be maximally queued for
1485 each probed SCSI device. You should reduce the default value of 8
1486 only if you have disks with buggy or limited tagged command support.
1487 Minimum is 2 and maximum is 14. This value is also the window size
1488 used by the elevator sorting option above. The effective value used
1489 by the driver for each probed SCSI device is reported at boot time.
1490 This is equivalent to the "u14-34f=mq:8" boot option.

1518 module will be called nsp32.
1521 tristate "SCSI debugging host simulator"
1525 This is a host adapter simulator that can simulate multiple hosts
1526 each with multiple dummy SCSI devices (disks). It defaults to one
1527 host adapter with one dummy SCSI disk. Each dummy disk uses kernel
1528 RAM as storage (i.e. it is a ramdisk). To save space when multiple
1529 dummy disks are simulated, they share the same kernel RAM for
1530 their storage. See <http://sg.danny.cz/sg/sdebug26.html> for more
1531 information. This driver is primarily of use to those testing the
1532 SCSI and block subsystems. If unsure, say N.

1548 depends on SCSI_MESH
1551 On Power Macintoshes (and clones) where the MESH SCSI bus adaptor
1552 drives a bus which is entirely internal to the machine (such as the
1553 7500, 7600, 8500, etc.), the MESH is capable of synchronous
1554 operation at up to 10 MB/s. On machines where the SCSI bus
1555 controlled by the MESH can have external devices connected, it is
1556 usually rated at 5 MB/s. 5 is a safe value here unless you know the
1557 MESH SCSI bus is internal only; in that case you can say 10. Say 0
1558 to disable synchronous operation.

1567 depends on PPC32 && PPC_PMAC && SCSI
1569 On Power Macintoshes (and clones) with two SCSI buses, the external
1570 SCSI bus is usually controlled by a 53C94 SCSI bus adaptor. Older
1571 machines which only have one SCSI bus, such as the 7200, also use
1572 the 53C94. Say Y to include support for the 53C94.
