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

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

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

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.

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 comment "Some SCSI devices (e.g. CD jukebox) support multiple LUNs"
197 config SCSI_MULTI_LUN
198 bool "Probe all LUNs on each SCSI device"
201 If you have a SCSI device that supports more than one LUN (Logical
202 Unit Number), e.g. a CD jukebox, and only one LUN is detected, you
203 can say Y here to force the SCSI driver to probe for multiple LUNs.
204 A SCSI device with multiple LUNs acts logically like multiple SCSI
205 devices. The vast majority of SCSI devices have only one LUN, and
206 so most people can say N here. The max_luns boot/module parameter
207 allows to override this setting.
209 config SCSI_CONSTANTS
210 bool "Verbose SCSI error reporting (kernel size +=12K)"
213 The error messages regarding your SCSI hardware will be easier to
214 understand if you say Y here; it will enlarge your kernel by about
215 12 KB. If in doubt, say Y.
218 bool "SCSI logging facility"
221 This turns on a logging facility that can be used to debug a number
222 of SCSI related problems.
224 If you say Y here, no logging output will appear by default, but you
225 can enable logging by saying Y to "/proc file system support" and
226 "Sysctl support" below and executing the command
228 echo <bitmask> > /proc/sys/dev/scsi/logging_level
230 where <bitmask> is a four byte value representing the logging type
231 and logging level for each type of logging selected.
233 There are a number of logging types and you can find them in the
234 source at <file:drivers/scsi/scsi_logging.h>. The logging levels
235 are also described in that file and they determine the verbosity of
236 the logging for each logging type.
238 If you say N here, it may be harder to track down some types of SCSI
239 problems. If you say Y here your kernel will be somewhat larger, but
240 there should be no noticeable performance impact as long as you have
243 config SCSI_SCAN_ASYNC
244 bool "Asynchronous SCSI scanning"
247 The SCSI subsystem can probe for devices while the rest of the
248 system continues booting, and even probe devices on different
249 busses in parallel, leading to a significant speed-up.
251 If you have built SCSI as modules, enabling this option can
252 be a problem as the devices may not have been found by the
253 time your system expects them to have been. You can load the
254 scsi_wait_scan module to ensure that all scans have completed.
255 If you build your SCSI drivers into the kernel, then everything
256 will work fine if you say Y here.
258 You can override this choice by specifying "scsi_mod.scan=sync"
259 or async on the kernel's command line.

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

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

729 NOTE: Newer Adaptec AHA-2920C boards use the Adaptec AIC-7850 chip
730 and should use the aic7xxx driver ("Adaptec AIC7xxx chipset SCSI

742 Some PS/2 computers are equipped with IBM Fast SCSI Adapter/A which
743 is identical to the MCS 700 and hence also supported by this driver.
744 This driver also supports the Reply SB16/SCSI card (the SCSI part).

769 This is a driver for the old NCR 53c80 series of SCSI controllers
770 on boards using PIO. Most boards such as the Trantor T130 fit this
771 category, along with a large number of ISA 8bit controllers shipped
772 for free with SCSI scanners. If you have a PAS16, T128 or DMX3191
773 you should select the specific driver for that card rather than
774 generic 5380 support.
776 It is explained in section 3.8 of the SCSI-HOWTO, available from
777 <http://www.tldp.org/docs.html#howto>. If it doesn't work out

803 This enables certain optimizations for the NCR53c400 SCSI cards.
804 You might as well try it out. Note that this driver will only probe
805 for the Trantor T130B in its default configuration; you might have
806 to pass a command line option to the kernel at boot time if it does
807 not detect your card. See the file
808 <file:Documentation/scsi/g_NCR5380.txt> for details.
811 tristate "IBMMCA SCSI support"
812 depends on MCA && SCSI
814 This is support for the IBM SCSI adapter found in many of the PS/2
815 series computers. These machines have an MCA bus, so you need to
816 answer Y to "MCA support" as well and read
817 <file:Documentation/mca.txt>.
819 If the adapter isn't found during boot (a common problem for models
820 56, 57, 76, and 77) you'll need to use the 'ibmmcascsi=<pun>' kernel
821 option, where <pun> is the id of the SCSI subsystem (usually 7, but
822 if that doesn't work check your reference diskette). Owners of
823 model 95 with a LED-matrix-display can in addition activate some
824 activity info like under OS/2, but more informative, by setting
825 'ibmmcascsi=display' as an additional kernel parameter. Try "man
826 bootparam" or see the documentation of your boot loader about how to
827 pass options to the kernel.

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

863 here. If unsure, say Y.
865 config IBMMCA_SCSI_DEV_RESET
866 bool "Reset SCSI-devices at boottime"
867 depends on SCSI_IBMMCA
869 By default, SCSI-devices are reset when the machine is powered on.
870 However, some devices exist, like special-control-devices,
871 SCSI-CNC-machines, SCSI-printer or scanners of older type, that do
872 not reset when switched on. If you say Y here, each device connected
873 to your SCSI-bus will be issued a reset-command after it has been
874 probed, while the kernel is booting. This may cause problems with
875 more modern devices, like hard disks, which do not appreciate these
876 reset commands, and can cause your system to hang. So say Y only if
877 you know that one of your older devices needs it; N is the safe

1032 Some parallel ports are known to have excessive delays between
1033 changing the parallel port control register and good data being
1034 available on the parallel port data/status register. This option
1035 forces a small delay (1.0 usec to be exact) after changing the

1136 capable (875A, 895A, 896, 1010-33, 1010-66, 1000).
1138 When set to 0, the driver will program the chip to only perform
1139 32-bit DMA. When set to 1, the chip will be able to perform DMA
1140 to addresses up to 1TB. When set to 2, the driver supports the
1141 full 64-bit DMA address range, but can only address 16 segments
1142 of 4 GB each. This limits the total addressable range to 64 GB.
1144 Most machines with less than 4GB of memory should use a setting
1145 of 0 for best performance. If your machine has 4GB of memory
1146 or more, you should set this option to 1 (the default).
1148 The still experimental value 2 (64 bit DMA addressing with 16
1149 x 4GB segments limitation) can be used on systems that require

1234 int "default tagged command queue depth"
1235 depends on SCSI_ZALON || SCSI_NCR_Q720
1238 "Tagged command queuing" is a feature of SCSI-2 which improves
1239 performance: the host adapter can send several SCSI commands to a
1240 device's queue even if previous commands haven't finished yet.
1241 Because the device is intelligent, it can optimize its operations
1242 (like head positioning) based on its own request queue. Some SCSI
1243 devices don't implement this properly; if you want to disable this
1244 feature, enter 0 or 1 here (it doesn't matter which).
1246 The default value is 8 and should be supported by most hard disks.
1247 This value can be overridden from the boot command line using the
1248 'tags' option as follows (example):
1249 'ncr53c8xx=tags:4/t2t3q16/t0u2q10' will set default queue depth to
1250 4, set queue depth to 16 for target 2 and target 3 on controller 0
1251 and set queue depth to 10 for target 0 / lun 2 on controller 1.
1253 The normal answer therefore is to go with the default 8 and to use
1254 a boot command line option for devices that need to use a different
1255 command queue depth.
1257 There is no safe option other than using good SCSI devices.
1259 config SCSI_NCR53C8XX_MAX_TAGS
1260 int "maximum number of queued commands"
1261 depends on SCSI_ZALON || SCSI_NCR_Q720
1264 This option allows you to specify the maximum number of commands
1265 that can be queued to any device, when tagged command queuing is
1266 possible. The default value is 32. Minimum is 2, maximum is 64.
1267 Modern hard disks are able to support 64 tags and even more, but
1268 do not seem to be faster when more than 32 tags are being used.
1270 So, the normal answer here is to go with the default value 32 unless
1271 you are using very large hard disks with large cache (>= 1 MB) that
1272 are able to take advantage of more than 32 tagged commands.
1274 There is no safe option and the default answer is recommended.

1278 depends on SCSI_ZALON || SCSI_NCR_Q720
1281 The SCSI Parallel Interface-2 Standard defines 5 classes of transfer
1282 rates: FAST-5, FAST-10, FAST-20, FAST-40 and FAST-80. The numbers
1283 are respectively the maximum data transfer rates in mega-transfers
1284 per second for each class. For example, a FAST-20 Wide 16 device is
1285 able to transfer data at 20 million 16 bit packets per second for a
1286 total rate of 40 MB/s.
1288 You may specify 0 if you want to only use asynchronous data
1289 transfers. This is the safest and slowest option. Otherwise, specify
1290 a value between 5 and 80, depending on the capability of your SCSI
1291 controller. The higher the number, the faster the data transfer.
1292 Note that 80 should normally be ok since the driver decreases the
1293 value automatically according to the controller's capabilities.
1295 Your answer to this question is ignored for controllers with NVRAM,
1296 since the driver will get this information from the user set-up. It
1297 also can be overridden using a boot setup option, as follows
1298 (example): 'ncr53c8xx=sync:12' will allow the driver to negotiate
1299 for FAST-20 synchronous data transfer (20 mega-transfers per
1302 The normal answer therefore is not to go with the default but to
1303 select the maximum value 80 allowing the driver to use the maximum
1304 value supported by each controller. If this causes problems with
1305 your SCSI devices, you should come back and decrease the value.
1307 There is no safe option other than using good cabling, right
1308 terminations and SCSI conformant devices.

1311 bool "not allow targets to disconnect"
1312 depends on (SCSI_ZALON || SCSI_NCR_Q720) && SCSI_NCR53C8XX_DEFAULT_TAGS=0
1314 This option is only provided for safety if you suspect some SCSI
1315 device of yours to not support properly the target-disconnect
1316 feature. In that case, you would say Y here. In general however, to
1317 not allow targets to disconnect is not reasonable if there is more
1318 than 1 device on a SCSI bus. The normal answer therefore is N.

1408 the sym53c416 is configured first using some sort of PnP
1409 configuration program (e.g. isapnp) or by a PnP aware BIOS. If you
1410 are using isapnp then you need to compile this driver as a module

1485 config SCSI_U14_34F_TAGGED_QUEUE
1486 bool "enable tagged command queueing"
1487 depends on SCSI_U14_34F
1489 This is a feature of SCSI-2 which improves performance: the host
1490 adapter can send several SCSI commands to a device's queue even if
1491 previous commands haven't finished yet.
1492 This is equivalent to the "u14-34f=tc:y" boot option.
1494 config SCSI_U14_34F_LINKED_COMMANDS
1495 bool "enable elevator sorting"
1496 depends on SCSI_U14_34F
1498 This option enables elevator sorting for all probed SCSI disks and
1499 CD-ROMs. It definitely reduces the average seek distance when doing
1500 random seeks, but this does not necessarily result in a noticeable
1501 performance improvement: your mileage may vary...
1502 This is equivalent to the "u14-34f=lc:y" boot option.
1504 config SCSI_U14_34F_MAX_TAGS
1505 int "maximum number of queued commands"
1506 depends on SCSI_U14_34F
1509 This specifies how many SCSI commands can be maximally queued for
1510 each probed SCSI device. You should reduce the default value of 8
1511 only if you have disks with buggy or limited tagged command support.
1512 Minimum is 2 and maximum is 14. This value is also the window size
1513 used by the elevator sorting option above. The effective value used
1514 by the driver for each probed SCSI device is reported at boot time.
1515 This is equivalent to the "u14-34f=mq:8" boot option.

1546 tristate "SCSI debugging host simulator"
1550 This is a host adapter simulator that can simulate multiple hosts
1551 each with multiple dummy SCSI devices (disks). It defaults to one
1552 host adapter with one dummy SCSI disk. Each dummy disk uses kernel
1553 RAM as storage (i.e. it is a ramdisk). To save space when multiple
1554 dummy disks are simulated, they share the same kernel RAM for
1555 their storage. See <http://www.torque.net/sg/sdebug.html> for more
1556 information. This driver is primarily of use to those testing the
1557 SCSI and block subsystems. If unsure, say N.

1576 On Power Macintoshes (and clones) where the MESH SCSI bus adaptor
1577 drives a bus which is entirely internal to the machine (such as the
1578 7500, 7600, 8500, etc.), the MESH is capable of synchronous
1579 operation at up to 10 MB/s. On machines where the SCSI bus
1580 controlled by the MESH can have external devices connected, it is
1581 usually rated at 5 MB/s. 5 is a safe value here unless you know the
1582 MESH SCSI bus is internal only; in that case you can say 10. Say 0
1583 to disable synchronous operation.
