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, and FireWire storage.

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

138 This enables the usage of vendor specific SCSI commands. This is
139 required to support multisession CDs with old NEC/TOSHIBA cdrom
140 drives (and HP Writers). If you have such a drive and get the first
141 session only, try saying Y here; everybody else says N.
144 tristate "SCSI generic support"
147 If you want to use SCSI scanners, synthesizers or CD-writers or just
148 about anything having "SCSI" in its name other than hard disks,
149 CD-ROMs or tapes, say Y here. These won't be supported by the kernel
150 directly, so you need some additional software which knows how to
151 talk to these devices using the SCSI protocol:
153 For scanners, look at SANE (<http://www.mostang.com/sane/>). For CD
154 writer software look at Cdrtools
155 (<http://www.fokus.gmd.de/research/cc/glone/employees/joerg.schilling/private/cdrecord.html>)
156 and for burning a "disk at once": CDRDAO
157 (<http://cdrdao.sourceforge.net/>). Cdparanoia is a high
158 quality digital reader of audio CDs (<http://www.xiph.org/paranoia/>).
159 For other devices, it's possible that you'll have to write the
160 driver software yourself. Please read the file
161 <file:Documentation/scsi/scsi-generic.txt> for more information.
163 To compile this driver as a module, choose M here and read
164 <file:Documentation/scsi/scsi.txt>. The module will be called sg.
169 tristate "SCSI media changer support"
172 This is a driver for SCSI media changers. Most common devices are
173 tape libraries and MOD/CDROM jukeboxes. *Real* jukeboxes, you
174 don't need this for those tiny 6-slot cdrom changers. Media
175 changers are listed as "Type: Medium Changer" in /proc/scsi/scsi.
176 If you have such hardware and want to use it with linux, say Y
177 here. Check <file:Documentation/scsi/scsi-changer.txt> for details.
179 If you want to compile this as a module ( = code which can be
180 inserted in and removed from the running kernel whenever you want),
181 say M here and read <file:Documentation/kbuild/modules.txt> and
182 <file:Documentation/scsi/scsi.txt>. The module will be called ch.o.
185 config SCSI_ENCLOSURE
186 tristate "SCSI Enclosure Support"
187 depends on SCSI && ENCLOSURE_SERVICES
189 Enclosures are devices sitting on or in SCSI backplanes that
190 manage devices. If you have a disk cage, the chances are that
191 it has an enclosure device. Selecting this option will just allow
192 certain enclosure conditions to be reported and is not required.
194 config SCSI_MULTI_LUN
195 bool "Probe all LUNs on each SCSI device"
198 Some devices support more than one LUN (Logical Unit Number) in order
199 to allow access to several media, e.g. CD jukebox, USB card reader,
200 mobile phone in mass storage mode. This option forces the kernel to
201 probe for all LUNs by default. This setting can be overriden by
202 max_luns boot/module parameter. Note that this option does not affect
203 devices conforming to SCSI-3 or higher as they can explicitely report
204 their number of LUNs. It is safe to say Y here unless you have one of
205 those rare devices which reacts in an unexpected way when probed for
208 config SCSI_CONSTANTS
209 bool "Verbose SCSI error reporting (kernel size +=12K)"
212 The error messages regarding your SCSI hardware will be easier to
213 understand if you say Y here; it will enlarge your kernel by about
214 12 KB. If in doubt, say Y.
217 bool "SCSI logging facility"
220 This turns on a logging facility that can be used to debug a number
221 of SCSI related problems.
223 If you say Y here, no logging output will appear by default, but you
224 can enable logging by saying Y to "/proc file system support" and
225 "Sysctl support" below and executing the command
227 echo <bitmask> > /proc/sys/dev/scsi/logging_level
229 where <bitmask> is a four byte value representing the logging type
230 and logging level for each type of logging selected.
232 There are a number of logging types and you can find them in the
233 source at <file:drivers/scsi/scsi_logging.h>. The logging levels
234 are also described in that file and they determine the verbosity of
235 the logging for each logging type.
237 If you say N here, it may be harder to track down some types of SCSI
238 problems. If you say Y here your kernel will be somewhat larger, but
239 there should be no noticeable performance impact as long as you have
242 config SCSI_SCAN_ASYNC
243 bool "Asynchronous SCSI scanning"
246 The SCSI subsystem can probe for devices while the rest of the
247 system continues booting, and even probe devices on different
248 busses in parallel, leading to a significant speed-up.
250 If you have built SCSI as modules, enabling this option can
251 be a problem as the devices may not have been found by the
252 time your system expects them to have been. You can load the
253 scsi_wait_scan module to ensure that all scans have completed.
254 If you build your SCSI drivers into the kernel, then everything
255 will work fine if you say Y here.
257 You can override this choice by specifying "scsi_mod.scan=sync"
258 or async on the kernel's command line.

342 SCSI requests and responses over a TCP/IP network between the host
343 (the "initiator") and "targets". Architecturally, the iSCSI driver

706 This specifies how many SCSI commands can be maximally queued for
707 each probed SCSI device. You should reduce the default value of 16
708 only if you have disks with buggy or limited tagged command support.
709 Minimum is 2 and maximum is 62. This value is also the window size
710 used by the elevator sorting option above. The effective value used
711 by the driver for each probed SCSI device is reported at boot time.
712 This is equivalent to the "eata=mq:8" boot option.

718 This driver supports all EATA-PIO protocol compliant SCSI Host
719 Adapters like the DPT PM2001 and the PM2012A. EATA-DMA compliant
720 host adapters could also use this driver but are discouraged from
721 doing so, since this driver only supports hard disks and lacks

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

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

822 tristate "IBMMCA SCSI support"
823 depends on MCA && SCSI
825 This is support for the IBM SCSI adapter found in many of the PS/2
826 series computers. These machines have an MCA bus, so you need to
827 answer Y to "MCA support" as well and read
828 <file:Documentation/mca.txt>.
830 If the adapter isn't found during boot (a common problem for models
831 56, 57, 76, and 77) you'll need to use the 'ibmmcascsi=<pun>' kernel
832 option, where <pun> is the id of the SCSI subsystem (usually 7, but
833 if that doesn't work check your reference diskette). Owners of
834 model 95 with a LED-matrix-display can in addition activate some
835 activity info like under OS/2, but more informative, by setting
836 'ibmmcascsi=display' as an additional kernel parameter. Try "man
837 bootparam" or see the documentation of your boot loader about how to
838 pass options to the kernel.

841 module will be called ibmmca.
843 config IBMMCA_SCSI_ORDER_STANDARD
844 bool "Standard SCSI-order"
845 depends on SCSI_IBMMCA
847 In the PC-world and in most modern SCSI-BIOS-setups, SCSI-hard disks
848 are assigned to the drive letters, starting with the lowest SCSI-id
849 (physical number -- pun) to be drive C:, as seen from DOS and
850 similar operating systems. When looking into papers describing the
851 ANSI-SCSI-standard, this assignment of drives appears to be wrong.
852 The SCSI-standard follows a hardware-hierarchy which says that id 7
853 has the highest priority and id 0 the lowest. Therefore, the host
854 adapters are still today everywhere placed as SCSI-id 7 by default.
855 In the SCSI-standard, the drive letters express the priority of the
856 disk. C: should be the hard disk, or a partition on it, with the
857 highest priority. This must therefore be the disk with the highest
858 SCSI-id (e.g. 6) and not the one with the lowest! IBM-BIOS kept the
859 original definition of the SCSI-standard as also industrial- and
860 process-control-machines, like VME-CPUs running under realtime-OSes
861 (e.g. LynxOS, OS9) do.
863 If you like to run Linux on your MCA-machine with the same
864 assignment of hard disks as seen from e.g. DOS or OS/2 on your
865 machine, which is in addition conformant to the SCSI-standard, you
866 must say Y here. This is also necessary for MCA-Linux users who want
867 to keep downward compatibility to older releases of the
868 IBM-MCA-SCSI-driver (older than driver-release 2.00 and older than
871 If you like to have the lowest SCSI-id assigned as drive C:, as
872 modern SCSI-BIOSes do, which does not conform to the standard, but

874 here. If unsure, say Y.
876 config IBMMCA_SCSI_DEV_RESET
877 bool "Reset SCSI-devices at boottime"

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

1043 Some parallel ports are known to have excessive delays between
1044 changing the parallel port control register and good data being
1045 available on the parallel port data/status register. This option
1046 forces a small delay (1.0 usec to be exact) after changing the

1137 capable (875A, 895A, 896, 1010-33, 1010-66, 1000).
1139 When set to 0, the driver will program the chip to only perform
1140 32-bit DMA. When set to 1, the chip will be able to perform DMA
1141 to addresses up to 1TB. When set to 2, the driver supports the
1142 full 64-bit DMA address range, but can only address 16 segments
1143 of 4 GB each. This limits the total addressable range to 64 GB.
1145 Most machines with less than 4GB of memory should use a setting
1146 of 0 for best performance. If your machine has 4GB of memory
1147 or more, you should set this option to 1 (the default).
1149 The still experimental value 2 (64 bit DMA addressing with 16

1235 int "default tagged command queue depth"
1236 depends on SCSI_ZALON || SCSI_NCR_Q720
1239 "Tagged command queuing" is a feature of SCSI-2 which improves
1240 performance: the host adapter can send several SCSI commands to a
1241 device's queue even if previous commands haven't finished yet.
1242 Because the device is intelligent, it can optimize its operations
1243 (like head positioning) based on its own request queue. Some SCSI
1244 devices don't implement this properly; if you want to disable this
1245 feature, enter 0 or 1 here (it doesn't matter which).
1247 The default value is 8 and should be supported by most hard disks.
1248 This value can be overridden from the boot command line using the
1249 'tags' option as follows (example):
1250 'ncr53c8xx=tags:4/t2t3q16/t0u2q10' will set default queue depth to
1251 4, set queue depth to 16 for target 2 and target 3 on controller 0
1252 and set queue depth to 10 for target 0 / lun 2 on controller 1.
1254 The normal answer therefore is to go with the default 8 and to use
1255 a boot command line option for devices that need to use a different
1256 command queue depth.
1258 There is no safe option other than using good SCSI devices.
1260 config SCSI_NCR53C8XX_MAX_TAGS
1261 int "maximum number of queued commands"

1265 This option allows you to specify the maximum number of commands
1266 that can be queued to any device, when tagged command queuing is
1267 possible. The default value is 32. Minimum is 2, maximum is 64.
1268 Modern hard disks are able to support 64 tags and even more, but
1269 do not seem to be faster when more than 32 tags are being used.
1271 So, the normal answer here is to go with the default value 32 unless
1272 you are using very large hard disks with large cache (>= 1 MB) that
1273 are able to take advantage of more than 32 tagged commands.
1275 There is no safe option and the default answer is recommended.

1278 int "synchronous transfers frequency in MHz"
1279 depends on SCSI_ZALON || SCSI_NCR_Q720
1282 The SCSI Parallel Interface-2 Standard defines 5 classes of transfer
1283 rates: FAST-5, FAST-10, FAST-20, FAST-40 and FAST-80. The numbers
1284 are respectively the maximum data transfer rates in mega-transfers
1285 per second for each class. For example, a FAST-20 Wide 16 device is
1286 able to transfer data at 20 million 16 bit packets per second for a
1287 total rate of 40 MB/s.
1289 You may specify 0 if you want to only use asynchronous data
1290 transfers. This is the safest and slowest option. Otherwise, specify
1291 a value between 5 and 80, depending on the capability of your SCSI
1292 controller. The higher the number, the faster the data transfer.
1293 Note that 80 should normally be ok since the driver decreases the
1294 value automatically according to the controller's capabilities.
1296 Your answer to this question is ignored for controllers with NVRAM,
1297 since the driver will get this information from the user set-up. It
1298 also can be overridden using a boot setup option, as follows
1299 (example): 'ncr53c8xx=sync:12' will allow the driver to negotiate
1300 for FAST-20 synchronous data transfer (20 mega-transfers per
1303 The normal answer therefore is not to go with the default but to
1304 select the maximum value 80 allowing the driver to use the maximum
1305 value supported by each controller. If this causes problems with
1306 your SCSI devices, you should come back and decrease the value.
1308 There is no safe option other than using good cabling, right
1309 terminations and SCSI conformant devices.

1312 bool "not allow targets to disconnect"
1313 depends on (SCSI_ZALON || SCSI_NCR_Q720) && SCSI_NCR53C8XX_DEFAULT_TAGS=0
1315 This option is only provided for safety if you suspect some SCSI
1316 device of yours to not support properly the target-disconnect
1317 feature. In that case, you would say Y here. In general however, to
1318 not allow targets to disconnect is not reasonable if there is more
1319 than 1 device on a SCSI bus. The normal answer therefore is N.

1409 the sym53c416 is configured first using some sort of PnP
1410 configuration program (e.g. isapnp) or by a PnP aware BIOS. If you
1411 are using isapnp then you need to compile this driver as a module

1486 config SCSI_U14_34F_TAGGED_QUEUE
1487 bool "enable tagged command queueing"
1488 depends on SCSI_U14_34F
1490 This is a feature of SCSI-2 which improves performance: the host
1491 adapter can send several SCSI commands to a device's queue even if
1492 previous commands haven't finished yet.
1493 This is equivalent to the "u14-34f=tc:y" boot option.
1495 config SCSI_U14_34F_LINKED_COMMANDS
1496 bool "enable elevator sorting"
1497 depends on SCSI_U14_34F
1499 This option enables elevator sorting for all probed SCSI disks and
1500 CD-ROMs. It definitely reduces the average seek distance when doing
1501 random seeks, but this does not necessarily result in a noticeable
1502 performance improvement: your mileage may vary...
1503 This is equivalent to the "u14-34f=lc:y" boot option.
1505 config SCSI_U14_34F_MAX_TAGS
1506 int "maximum number of queued commands"
1507 depends on SCSI_U14_34F
1510 This specifies how many SCSI commands can be maximally queued for
1511 each probed SCSI device. You should reduce the default value of 8
1512 only if you have disks with buggy or limited tagged command support.
1513 Minimum is 2 and maximum is 14. This value is also the window size
1514 used by the elevator sorting option above. The effective value used
1515 by the driver for each probed SCSI device is reported at boot time.
1516 This is equivalent to the "u14-34f=mq:8" boot option.

1547 tristate "SCSI debugging host simulator"
1551 This is a host adapter simulator that can simulate multiple hosts
1552 each with multiple dummy SCSI devices (disks). It defaults to one
1553 host adapter with one dummy SCSI disk. Each dummy disk uses kernel
1554 RAM as storage (i.e. it is a ramdisk). To save space when multiple
1555 dummy disks are simulated, they share the same kernel RAM for
1556 their storage. See <http://www.torque.net/sg/sdebug.html> for more
1557 information. This driver is primarily of use to those testing the
1558 SCSI and block subsystems. If unsure, say N.

1577 On Power Macintoshes (and clones) where the MESH SCSI bus adaptor
1578 drives a bus which is entirely internal to the machine (such as the
1579 7500, 7600, 8500, etc.), the MESH is capable of synchronous
1580 operation at up to 10 MB/s. On machines where the SCSI bus
1581 controlled by the MESH can have external devices connected, it is
1582 usually rated at 5 MB/s. 5 is a safe value here unless you know the
1583 MESH SCSI bus is internal only; in that case you can say 10. Say 0
1584 to disable synchronous operation.
