15 If you want to use a SCSI hard disk, SCSI tape drive, SCSI CD-ROM or
16 any other SCSI device under Linux, say Y and make sure that you know
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.

98 tristate "SCSI OnStream SC-x0 tape support"
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
109 <http://www.tldp.org/docs.html#howto> and
110 <file:Documentation/scsi/osst.txt> in the kernel source.
111 More info on the OnStream driver may be found on

138 drives (and HP Writers). If you have such a drive and get the first
139 session only, try saying Y here; everybody else says N.
142 tristate "SCSI generic support"
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
159 <file:Documentation/scsi/scsi-generic.txt> for more information.
161 To compile this driver as a module, choose M here and read

167 tristate "SCSI media changer support"
170 This is a driver for SCSI media changers. Most common devices are
171 tape libraries and MOD/CDROM jukeboxes. *Real* jukeboxes, you
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.
174 If you have such hardware and want to use it with linux, say Y
175 here. Check <file:Documentation/scsi-changer.txt> for details.
177 If you want to compile this as a module ( = code which can be
178 inserted in and removed from the running kernel whenever you want),

184 comment "Some SCSI devices (e.g. CD jukebox) support multiple LUNs"
187 config SCSI_MULTI_LUN
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.

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

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

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

757 tristate "IBMMCA SCSI support"
758 depends on MCA && SCSI
760 This is support for the IBM SCSI adapter found in many of the PS/2
761 series computers. These machines have an MCA bus, so you need to
762 answer Y to "MCA support" as well and read
763 <file:Documentation/mca.txt>.
765 If the adapter isn't found during boot (a common problem for models
766 56, 57, 76, and 77) you'll need to use the 'ibmmcascsi=<pun>' kernel
767 option, where <pun> is the id of the SCSI subsystem (usually 7, but
768 if that doesn't work check your reference diskette). Owners of
769 model 95 with a LED-matrix-display can in addition activate some
770 activity info like under OS/2, but more informative, by setting
771 'ibmmcascsi=display' as an additional kernel parameter. Try "man
772 bootparam" or see the documentation of your boot loader about how to
773 pass options to the kernel.

778 config IBMMCA_SCSI_ORDER_STANDARD
779 bool "Standard SCSI-order"
780 depends on SCSI_IBMMCA
782 In the PC-world and in most modern SCSI-BIOS-setups, SCSI-hard disks
783 are assigned to the drive letters, starting with the lowest SCSI-id
784 (physical number -- pun) to be drive C:, as seen from DOS and
785 similar operating systems. When looking into papers describing the
786 ANSI-SCSI-standard, this assignment of drives appears to be wrong.
787 The SCSI-standard follows a hardware-hierarchy which says that id 7
788 has the highest priority and id 0 the lowest. Therefore, the host
789 adapters are still today everywhere placed as SCSI-id 7 by default.
790 In the SCSI-standard, the drive letters express the priority of the
791 disk. C: should be the hard disk, or a partition on it, with the
792 highest priority. This must therefore be the disk with the highest
793 SCSI-id (e.g. 6) and not the one with the lowest! IBM-BIOS kept the
794 original definition of the SCSI-standard as also industrial- and
795 process-control-machines, like VME-CPUs running under realtime-OSes
796 (e.g. LynxOS, OS9) do.
798 If you like to run Linux on your MCA-machine with the same
799 assignment of hard disks as seen from e.g. DOS or OS/2 on your
800 machine, which is in addition conformant to the SCSI-standard, you
801 must say Y here. This is also necessary for MCA-Linux users who want
802 to keep downward compatibility to older releases of the
803 IBM-MCA-SCSI-driver (older than driver-release 2.00 and older than
806 If you like to have the lowest SCSI-id assigned as drive C:, as
807 modern SCSI-BIOSes do, which does not conform to the standard, but

809 here. If unsure, say Y.
811 config IBMMCA_SCSI_DEV_RESET
812 bool "Reset SCSI-devices at boottime"

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

958 Some parallel ports are known to have excessive delays between

1052 capable (875A, 895A, 896, 1010-33, 1010-66, 1000).
1054 When set to 0, the driver will program the chip to only perform
1055 32-bit DMA. When set to 1, the chip will be able to perform DMA
1056 to addresses up to 1TB. When set to 2, the driver supports the
1057 full 64-bit DMA address range, but can only address 16 segments
1058 of 4 GB each. This limits the total addressable range to 64 GB.
1060 Most machines with less than 4GB of memory should use a setting
1061 of 0 for best performance. If your machine has 4GB of memory
1062 or more, you should set this option to 1 (the default).
1064 The still experimental value 2 (64 bit DMA addressing with 16
1065 x 4GB segments limitation) can be used on systems that require
1066 PCI address bits past bit 39 to be set for the addressing of

1143 NCR and commonly used in 345x/35xx/4100 class machines. It always

1149 config SCSI_NCR53C8XX_DEFAULT_TAGS
1150 int "default tagged command queue depth"
1151 depends on SCSI_ZALON || SCSI_NCR_Q720
1154 "Tagged command queuing" is a feature of SCSI-2 which improves
1155 performance: the host adapter can send several SCSI commands to a
1156 device's queue even if previous commands haven't finished yet.
1157 Because the device is intelligent, it can optimize its operations
1158 (like head positioning) based on its own request queue. Some SCSI
1159 devices don't implement this properly; if you want to disable this
1160 feature, enter 0 or 1 here (it doesn't matter which).
1162 The default value is 8 and should be supported by most hard disks.
1163 This value can be overridden from the boot command line using the
1164 'tags' option as follows (example):
1165 'ncr53c8xx=tags:4/t2t3q16/t0u2q10' will set default queue depth to
1166 4, set queue depth to 16 for target 2 and target 3 on controller 0
1167 and set queue depth to 10 for target 0 / lun 2 on controller 1.
1169 The normal answer therefore is to go with the default 8 and to use
1170 a boot command line option for devices that need to use a different
1171 command queue depth.
1173 There is no safe option other than using good SCSI devices.
1175 config SCSI_NCR53C8XX_MAX_TAGS
1176 int "maximum number of queued commands"
1177 depends on SCSI_ZALON || SCSI_NCR_Q720
1180 This option allows you to specify the maximum number of commands
1181 that can be queued to any device, when tagged command queuing is
1182 possible. The default value is 32. Minimum is 2, maximum is 64.
1183 Modern hard disks are able to support 64 tags and even more, but
1184 do not seem to be faster when more than 32 tags are being used.
1186 So, the normal answer here is to go with the default value 32 unless
1187 you are using very large hard disks with large cache (>= 1 MB) that
1188 are able to take advantage of more than 32 tagged commands.
1190 There is no safe option and the default answer is recommended.
1192 config SCSI_NCR53C8XX_SYNC
1193 int "synchronous transfers frequency in MHz"
1194 depends on SCSI_ZALON || SCSI_NCR_Q720
1197 The SCSI Parallel Interface-2 Standard defines 5 classes of transfer
1198 rates: FAST-5, FAST-10, FAST-20, FAST-40 and FAST-80. The numbers
1199 are respectively the maximum data transfer rates in mega-transfers
1200 per second for each class. For example, a FAST-20 Wide 16 device is
1201 able to transfer data at 20 million 16 bit packets per second for a
1202 total rate of 40 MB/s.
1204 You may specify 0 if you want to only use asynchronous data
1205 transfers. This is the safest and slowest option. Otherwise, specify
1206 a value between 5 and 80, depending on the capability of your SCSI
1207 controller. The higher the number, the faster the data transfer.
1208 Note that 80 should normally be ok since the driver decreases the
1209 value automatically according to the controller's capabilities.
1211 Your answer to this question is ignored for controllers with NVRAM,
1212 since the driver will get this information from the user set-up. It
1213 also can be overridden using a boot setup option, as follows
1214 (example): 'ncr53c8xx=sync:12' will allow the driver to negotiate
1215 for FAST-20 synchronous data transfer (20 mega-transfers per
1218 The normal answer therefore is not to go with the default but to
1219 select the maximum value 80 allowing the driver to use the maximum
1220 value supported by each controller. If this causes problems with
1221 your SCSI devices, you should come back and decrease the value.
1223 There is no safe option other than using good cabling, right
1224 terminations and SCSI conformant devices.

1230 This option is only provided for safety if you suspect some SCSI
1231 device of yours to not support properly the target-disconnect
1232 feature. In that case, you would say Y here. In general however, to
1233 not allow targets to disconnect is not reasonable if there is more
1234 than 1 device on a SCSI bus. The normal answer therefore is N.

1361 the sym53c416 is configured first using some sort of PnP
1362 configuration program (e.g. isapnp) or by a PnP aware BIOS. If you
1363 are using isapnp then you need to compile this driver as a module

1437 config SCSI_U14_34F_TAGGED_QUEUE
1438 bool "enable tagged command queueing"
1439 depends on SCSI_U14_34F
1441 This is a feature of SCSI-2 which improves performance: the host
1442 adapter can send several SCSI commands to a device's queue even if
1443 previous commands haven't finished yet.
1444 This is equivalent to the "u14-34f=tc:y" boot option.
1446 config SCSI_U14_34F_LINKED_COMMANDS
1447 bool "enable elevator sorting"
1448 depends on SCSI_U14_34F
1450 This option enables elevator sorting for all probed SCSI disks and
1451 CD-ROMs. It definitely reduces the average seek distance when doing
1452 random seeks, but this does not necessarily result in a noticeable
1453 performance improvement: your mileage may vary...
1454 This is equivalent to the "u14-34f=lc:y" boot option.
1456 config SCSI_U14_34F_MAX_TAGS
1457 int "maximum number of queued commands"
1458 depends on SCSI_U14_34F
1461 This specifies how many SCSI commands can be maximally queued for
1462 each probed SCSI device. You should reduce the default value of 8
1463 only if you have disks with buggy or limited tagged command support.
1464 Minimum is 2 and maximum is 14. This value is also the window size
1465 used by the elevator sorting option above. The effective value used
1466 by the driver for each probed SCSI device is reported at boot time.
1467 This is equivalent to the "u14-34f=mq:8" boot option.

1498 tristate "SCSI debugging host simulator"
1501 This is a host adapter simulator that can simulate multiple hosts
1502 each with multiple dummy SCSI devices (disks). It defaults to one
1503 host adapter with one dummy SCSI disk. Each dummy disk uses kernel
1504 RAM as storage (i.e. it is a ramdisk). To save space when multiple
1505 dummy disks are simulated, they share the same kernel RAM for
1506 their storage. See <http://www.torque.net/sg/sdebug.html> for more
1507 information. This driver is primarily of use to those testing the
1508 SCSI and block subsystems. If unsure, say N.

1524 depends on SCSI_MESH
1527 On Power Macintoshes (and clones) where the MESH SCSI bus adaptor
1528 drives a bus which is entirely internal to the machine (such as the
1529 7500, 7600, 8500, etc.), the MESH is capable of synchronous
1530 operation at up to 10 MB/s. On machines where the SCSI bus
1531 controlled by the MESH can have external devices connected, it is
1532 usually rated at 5 MB/s. 5 is a safe value here unless you know the
1533 MESH SCSI bus is internal only; in that case you can say 10. Say 0
1534 to disable synchronous operation.

1543 depends on PPC32 && PPC_PMAC && SCSI
1545 On Power Macintoshes (and clones) with two SCSI buses, the external
1546 SCSI bus is usually controlled by a 53C94 SCSI bus adaptor. Older
1547 machines which only have one SCSI bus, such as the 7200, also use
1548 the 53C94. Say Y to include support for the 53C94.
