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
113 <http://linux1.onstream.nl/test/>
114 Please also have a look at the standard st docu, as most of it
115 applies to osst as well.

121 tristate "SCSI CDROM support"
124 If you want to use a CD or DVD drive attached to your computer
125 by SCSI, FireWire, USB or ATAPI, say Y and read the SCSI-HOWTO
126 and the CDROM-HOWTO at <http://www.tldp.org/docs.html#howto>.
128 Make sure to say Y or M to "ISO 9660 CD-ROM file system support".

136 depends on BLK_DEV_SR
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.
260 config SCSI_WAIT_SCAN
261 tristate # No prompt here, this is an invisible symbol.
265 # scsi_wait_scan is a loadable module which waits until all the async scans are
266 # complete. The idea is to use it in initrd/ initramfs scripts. You modprobe
267 # it after all the modprobes of the root SCSI drivers and it will wait until
268 # they have all finished scanning their buses before allowing the boot to
269 # proceed. (This method is not applicable if targets boot independently in
270 # parallel with the initiator, or with transports with non-deterministic target
271 # discovery schemes, or if a transport driver does not support scsi_wait_scan.)
273 # This symbol is not exposed as a prompt because little is to be gained by
274 # disabling it, whereas people who accidentally switch it off may wonder why
275 # their mkinitrd gets into trouble.

351 The iSCSI Driver provides a host with the ability to access storage
352 through an IP network. The driver uses the iSCSI protocol to transport
353 SCSI requests and responses over a TCP/IP network between the host
354 (the "initiator") and "targets". Architecturally, the iSCSI driver

694 config SCSI_EATA_TAGGED_QUEUE
695 bool "enable tagged command queueing"
698 This is a feature of SCSI-2 which improves performance: the host
699 adapter can send several SCSI commands to a device's queue even if
700 previous commands haven't finished yet.
701 This is equivalent to the "eata=tc:y" boot option.
703 config SCSI_EATA_LINKED_COMMANDS
704 bool "enable elevator sorting"
707 This option enables elevator sorting for all probed SCSI disks and
708 CD-ROMs. It definitely reduces the average seek distance when doing
709 random seeks, but this does not necessarily result in a noticeable
710 performance improvement: your mileage may vary...
711 This is equivalent to the "eata=lc:y" boot option.
713 config SCSI_EATA_MAX_TAGS
714 int "maximum number of queued commands"
718 This specifies how many SCSI commands can be maximally queued for
719 each probed SCSI device. You should reduce the default value of 16
720 only if you have disks with buggy or limited tagged command support.
721 Minimum is 2 and maximum is 62. This value is also the window size
722 used by the elevator sorting option above. The effective value used
723 by the driver for each probed SCSI device is reported at boot time.
724 This is equivalent to the "eata=mq:8" boot option.

730 This driver supports all EATA-PIO protocol compliant SCSI Host
731 Adapters like the DPT PM2001 and the PM2012A. EATA-DMA compliant
732 host adapters could also use this driver but are discouraged from
733 doing so, since this driver only supports hard disks and lacks
734 numerous features. You might want to have a look at the SCSI-HOWTO,

765 Some PS/2 computers are equipped with IBM Fast SCSI Adapter/A which
766 is identical to the MCS 700 and hence also supported by this driver.

789 depends on ISA && SCSI
790 select SCSI_SPI_ATTRS
792 This is a driver for the old NCR 53c80 series of SCSI controllers
793 on boards using PIO. Most boards such as the Trantor T130 fit this
794 category, along with a large number of ISA 8bit controllers shipped
795 for free with SCSI scanners. If you have a PAS16, T128 or DMX3191
796 you should select the specific driver for that card rather than
797 generic 5380 support.
799 It is explained in section 3.8 of the SCSI-HOWTO, available from
800 <http://www.tldp.org/docs.html#howto>. If it doesn't work out

826 This enables certain optimizations for the NCR53c400 SCSI cards.
827 You might as well try it out. Note that this driver will only probe
828 for the Trantor T130B in its default configuration; you might have
829 to pass a command line option to the kernel at boot time if it does
830 not detect your card. See the file
831 <file:Documentation/scsi/g_NCR5380.txt> for details.
834 tristate "IBMMCA SCSI support"
835 depends on MCA && SCSI
837 This is support for the IBM SCSI adapter found in many of the PS/2
838 series computers. These machines have an MCA bus, so you need to
839 answer Y to "MCA support" as well and read
840 <file:Documentation/mca.txt>.
842 If the adapter isn't found during boot (a common problem for models
843 56, 57, 76, and 77) you'll need to use the 'ibmmcascsi=<pun>' kernel
844 option, where <pun> is the id of the SCSI subsystem (usually 7, but
845 if that doesn't work check your reference diskette). Owners of
846 model 95 with a LED-matrix-display can in addition activate some
847 activity info like under OS/2, but more informative, by setting
848 'ibmmcascsi=display' as an additional kernel parameter. Try "man
849 bootparam" or see the documentation of your boot loader about how to
850 pass options to the kernel.

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

886 here. If unsure, say Y.
888 config IBMMCA_SCSI_DEV_RESET
889 bool "Reset SCSI-devices at boottime"
890 depends on SCSI_IBMMCA
892 By default, SCSI-devices are reset when the machine is powered on.
893 However, some devices exist, like special-control-devices,
894 SCSI-CNC-machines, SCSI-printer or scanners of older type, that do
895 not reset when switched on. If you say Y here, each device connected
896 to your SCSI-bus will be issued a reset-command after it has been
897 probed, while the kernel is booting. This may cause problems with
898 more modern devices, like hard disks, which do not appreciate these
899 reset commands, and can cause your system to hang. So say Y only if
900 you know that one of your older devices needs it; N is the safe

1055 Some parallel ports are known to have excessive delays between
1056 changing the parallel port control register and good data being
1057 available on the parallel port data/status register. This option
1058 forces a small delay (1.0 usec to be exact) after changing the

1149 capable (875A, 895A, 896, 1010-33, 1010-66, 1000).
1151 When set to 0, the driver will program the chip to only perform
1152 32-bit DMA. When set to 1, the chip will be able to perform DMA
1153 to addresses up to 1TB. When set to 2, the driver supports the
1154 full 64-bit DMA address range, but can only address 16 segments
1155 of 4 GB each. This limits the total addressable range to 64 GB.
1157 Most machines with less than 4GB of memory should use a setting
1158 of 0 for best performance. If your machine has 4GB of memory
1159 or more, you should set this option to 1 (the default).
1161 The still experimental value 2 (64 bit DMA addressing with 16
1162 x 4GB segments limitation) can be used on systems that require

1247 int "default tagged command queue depth"
1248 depends on SCSI_ZALON || SCSI_NCR_Q720
1251 "Tagged command queuing" is a feature of SCSI-2 which improves
1252 performance: the host adapter can send several SCSI commands to a
1253 device's queue even if previous commands haven't finished yet.
1254 Because the device is intelligent, it can optimize its operations
1255 (like head positioning) based on its own request queue. Some SCSI
1256 devices don't implement this properly; if you want to disable this
1257 feature, enter 0 or 1 here (it doesn't matter which).
1259 The default value is 8 and should be supported by most hard disks.
1260 This value can be overridden from the boot command line using the
1261 'tags' option as follows (example):
1262 'ncr53c8xx=tags:4/t2t3q16/t0u2q10' will set default queue depth to
1263 4, set queue depth to 16 for target 2 and target 3 on controller 0
1264 and set queue depth to 10 for target 0 / lun 2 on controller 1.
1266 The normal answer therefore is to go with the default 8 and to use
1267 a boot command line option for devices that need to use a different
1268 command queue depth.
1270 There is no safe option other than using good SCSI devices.
1272 config SCSI_NCR53C8XX_MAX_TAGS
1273 int "maximum number of queued commands"
1274 depends on SCSI_ZALON || SCSI_NCR_Q720
1277 This option allows you to specify the maximum number of commands
1278 that can be queued to any device, when tagged command queuing is
1279 possible. The default value is 32. Minimum is 2, maximum is 64.
1280 Modern hard disks are able to support 64 tags and even more, but
1281 do not seem to be faster when more than 32 tags are being used.
1283 So, the normal answer here is to go with the default value 32 unless
1284 you are using very large hard disks with large cache (>= 1 MB) that
1285 are able to take advantage of more than 32 tagged commands.
1287 There is no safe option and the default answer is recommended.
1289 config SCSI_NCR53C8XX_SYNC
1290 int "synchronous transfers frequency in MHz"
1291 depends on SCSI_ZALON || SCSI_NCR_Q720
1294 The SCSI Parallel Interface-2 Standard defines 5 classes of transfer
1295 rates: FAST-5, FAST-10, FAST-20, FAST-40 and FAST-80. The numbers
1296 are respectively the maximum data transfer rates in mega-transfers
1297 per second for each class. For example, a FAST-20 Wide 16 device is
1298 able to transfer data at 20 million 16 bit packets per second for a
1299 total rate of 40 MB/s.
1301 You may specify 0 if you want to only use asynchronous data
1302 transfers. This is the safest and slowest option. Otherwise, specify
1303 a value between 5 and 80, depending on the capability of your SCSI
1304 controller. The higher the number, the faster the data transfer.
1305 Note that 80 should normally be ok since the driver decreases the
1306 value automatically according to the controller's capabilities.
1308 Your answer to this question is ignored for controllers with NVRAM,
1309 since the driver will get this information from the user set-up. It
1310 also can be overridden using a boot setup option, as follows
1311 (example): 'ncr53c8xx=sync:12' will allow the driver to negotiate
1312 for FAST-20 synchronous data transfer (20 mega-transfers per
1315 The normal answer therefore is not to go with the default but to
1316 select the maximum value 80 allowing the driver to use the maximum
1317 value supported by each controller. If this causes problems with
1318 your SCSI devices, you should come back and decrease the value.
1320 There is no safe option other than using good cabling, right
1321 terminations and SCSI conformant devices.
1323 config SCSI_NCR53C8XX_NO_DISCONNECT
1324 bool "not allow targets to disconnect"
1325 depends on (SCSI_ZALON || SCSI_NCR_Q720) && SCSI_NCR53C8XX_DEFAULT_TAGS=0
1327 This option is only provided for safety if you suspect some SCSI
1328 device of yours to not support properly the target-disconnect
1329 feature. In that case, you would say Y here. In general however, to
1330 not allow targets to disconnect is not reasonable if there is more
1331 than 1 device on a SCSI bus. The normal answer therefore is N.

1421 the sym53c416 is configured first using some sort of PnP
1422 configuration program (e.g. isapnp) or by a PnP aware BIOS. If you
1423 are using isapnp then you need to compile this driver as a module

1498 config SCSI_U14_34F_TAGGED_QUEUE
1499 bool "enable tagged command queueing"
1500 depends on SCSI_U14_34F
1502 This is a feature of SCSI-2 which improves performance: the host
1503 adapter can send several SCSI commands to a device's queue even if
1504 previous commands haven't finished yet.
1505 This is equivalent to the "u14-34f=tc:y" boot option.

1508 bool "enable elevator sorting"
1509 depends on SCSI_U14_34F
1511 This option enables elevator sorting for all probed SCSI disks and
1512 CD-ROMs. It definitely reduces the average seek distance when doing
1513 random seeks, but this does not necessarily result in a noticeable
1514 performance improvement: your mileage may vary...
1515 This is equivalent to the "u14-34f=lc:y" boot option.
1517 config SCSI_U14_34F_MAX_TAGS
1518 int "maximum number of queued commands"
1519 depends on SCSI_U14_34F
1522 This specifies how many SCSI commands can be maximally queued for
1523 each probed SCSI device. You should reduce the default value of 8
1524 only if you have disks with buggy or limited tagged command support.
1525 Minimum is 2 and maximum is 14. This value is also the window size
1526 used by the elevator sorting option above. The effective value used
1527 by the driver for each probed SCSI device is reported at boot time.

1559 tristate "SCSI debugging host simulator"
1563 This is a host adapter simulator that can simulate multiple hosts
1564 each with multiple dummy SCSI devices (disks). It defaults to one
1565 host adapter with one dummy SCSI disk. Each dummy disk uses kernel
1566 RAM as storage (i.e. it is a ramdisk). To save space when multiple
1567 dummy disks are simulated, they share the same kernel RAM for
1568 their storage. See <http://www.torque.net/sg/sdebug.html> for more
1569 information. This driver is primarily of use to those testing the

1589 On Power Macintoshes (and clones) where the MESH SCSI bus adaptor
1590 drives a bus which is entirely internal to the machine (such as the
1591 7500, 7600, 8500, etc.), the MESH is capable of synchronous
1592 operation at up to 10 MB/s. On machines where the SCSI bus
1593 controlled by the MESH can have external devices connected, it is
1594 usually rated at 5 MB/s. 5 is a safe value here unless you know the
1595 MESH SCSI bus is internal only; in that case you can say 10. Say 0
1596 to disable synchronous operation.
