14 If you want to use a SCSI hard disk, SCSI tape drive, SCSI CD-ROM or
15 any other SCSI device under Linux, say Y and make sure that you know
16 the name of your SCSI host adapter (the card inside your computer
17 that "speaks" the SCSI protocol, also called SCSI controller),
18 because you will be asked for it.
20 You also need to say Y here if you have a device which speaks
21 the SCSI protocol. Examples of this include the parallel port
22 version of the IOMEGA ZIP drive, USB storage devices, Fibre
23 Channel, FireWire storage and the IDE-SCSI emulation driver.
25 To compile this driver as a module, choose M here and read
26 <file:Documentation/scsi/scsi.txt>.
27 The module will be called scsi_mod.
29 However, do not compile this as a module if your root file system
30 (the one containing the directory /) is located on a SCSI device.

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

132 required to support multisession CDs with old NEC/TOSHIBA cdrom
133 drives (and HP Writers). If you have such a drive and get the first
134 session only, try saying Y here; everybody else says N.
137 tristate "SCSI generic support"
140 If you want to use SCSI scanners, synthesizers or CD-writers or just
141 about anything having "SCSI" in its name other than hard disks,
142 CD-ROMs or tapes, say Y here. These won't be supported by the kernel
143 directly, so you need some additional software which knows how to
144 talk to these devices using the SCSI protocol:
146 For scanners, look at SANE (<http://www.mostang.com/sane/>). For CD
147 writer software look at Cdrtools
148 (<http://www.fokus.gmd.de/research/cc/glone/employees/joerg.schilling/private/cdrecord.html>)
149 and for burning a "disk at once": CDRDAO
150 (<http://cdrdao.sourceforge.net/>). Cdparanoia is a high
151 quality digital reader of audio CDs (<http://www.xiph.org/paranoia/>).
152 For other devices, it's possible that you'll have to write the
153 driver software yourself. Please read the file
154 <file:Documentation/scsi/scsi-generic.txt> for more information.
156 To compile this driver as a module, choose M here and read
157 <file:Documentation/scsi/scsi.txt>. The module will be called sg.
162 tristate "SCSI media changer support"
165 This is a driver for SCSI media changers. Most common devices are
166 tape libraries and MOD/CDROM jukeboxes. *Real* jukeboxes, you
167 don't need this for those tiny 6-slot cdrom changers. Media
168 changers are listed as "Type: Medium Changer" in /proc/scsi/scsi.
169 If you have such hardware and want to use it with linux, say Y
170 here. Check <file:Documentation/scsi-changer.txt> for details.
172 If you want to compile this as a module ( = code which can be
173 inserted in and removed from the running kernel whenever you want),
174 say M here and read <file:Documentation/kbuild/modules.txt> and
175 <file:Documentation/scsi.txt>. The module will be called ch.o.
179 comment "Some SCSI devices (e.g. CD jukebox) support multiple LUNs"
182 config SCSI_MULTI_LUN
183 bool "Probe all LUNs on each SCSI device"
186 If you have a SCSI device that supports more than one LUN (Logical
187 Unit Number), e.g. a CD jukebox, and only one LUN is detected, you
188 can say Y here to force the SCSI driver to probe for multiple LUNs.
189 A SCSI device with multiple LUNs acts logically like multiple SCSI
190 devices. The vast majority of SCSI devices have only one LUN, and
191 so most people can say N here. The max_luns boot/module parameter
192 allows to override this setting.
194 config SCSI_CONSTANTS
195 bool "Verbose SCSI error reporting (kernel size +=12K)"
198 The error messages regarding your SCSI hardware will be easier to
199 understand if you say Y here; it will enlarge your kernel by about
200 12 KB. If in doubt, say Y.
203 bool "SCSI logging facility"
206 This turns on a logging facility that can be used to debug a number
207 of SCSI related problems.
209 If you say Y here, no logging output will appear by default, but you
210 can enable logging by saying Y to "/proc file system support" and
211 "Sysctl support" below and executing the command
213 echo "scsi log token [level]" > /proc/scsi/scsi
215 at boot time after the /proc file system has been mounted.
217 There are a number of things that can be used for 'token' (you can
218 find them in the source: <file:drivers/scsi/scsi.c>), and this
219 allows you to select the types of information you want, and the
220 level allows you to select the level of verbosity.
222 If you say N here, it may be harder to track down some types of SCSI
223 problems. If you say Y here your kernel will be somewhat larger, but
224 there should be no noticeable performance impact as long as you have
227 config SCSI_SCAN_ASYNC
228 bool "Asynchronous SCSI scanning"
231 The SCSI subsystem can probe for devices while the rest of the
232 system continues booting, and even probe devices on different
233 busses in parallel, leading to a significant speed-up.
235 If you have built SCSI as modules, enabling this option can
236 be a problem as the devices may not have been found by the
237 time your system expects them to have been. You can load the
238 scsi_wait_scan module to ensure that all scans have completed.
239 If you build your SCSI drivers into the kernel, then everything
240 will work fine if you say Y here.
242 You can override this choice by specifying "scsi_mod.scan=sync"
243 or async on the kernel's command line.

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

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

734 You might as well try it out. Note that this driver will only probe
735 for the Trantor T130B in its default configuration; you might have
736 to pass a command line option to the kernel at boot time if it does
737 not detect your card. See the file

741 tristate "IBMMCA SCSI support"
742 depends on MCA_LEGACY && SCSI
744 This is support for the IBM SCSI adapter found in many of the PS/2
745 series computers. These machines have an MCA bus, so you need to
746 answer Y to "MCA support" as well and read
747 <file:Documentation/mca.txt>.
749 If the adapter isn't found during boot (a common problem for models
750 56, 57, 76, and 77) you'll need to use the 'ibmmcascsi=<pun>' kernel
751 option, where <pun> is the id of the SCSI subsystem (usually 7, but
752 if that doesn't work check your reference diskette). Owners of
753 model 95 with a LED-matrix-display can in addition activate some
754 activity info like under OS/2, but more informative, by setting
755 'ibmmcascsi=display' as an additional kernel parameter. Try "man
756 bootparam" or see the documentation of your boot loader about how to
757 pass options to the kernel.

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

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

941 Some parallel ports are known to have excessive delays between
942 changing the parallel port control register and good data being
943 available on the parallel port data/status register. This option
944 forces a small delay (1.0 usec to be exact) after changing the
945 control register to let things settle out. Enabling this option may
946 result in a big drop in performance but some very old parallel ports

1030 capable (875A, 895A, 896, 1010-33, 1010-66, 1000).
1032 When set to 0, the driver will program the chip to only perform
1033 32-bit DMA. When set to 1, the chip will be able to perform DMA
1034 to addresses up to 1TB. When set to 2, the driver supports the
1035 full 64-bit DMA address range, but can only address 16 segments
1036 of 4 GB each. This limits the total addressable range to 64 GB.
1038 Most machines with less than 4GB of memory should use a setting
1039 of 0 for best performance. If your machine has 4GB of memory
1040 or more, you should set this option to 1 (the default).
1042 The still experimental value 2 (64 bit DMA addressing with 16
1043 x 4GB segments limitation) can be used on systems that require
1044 PCI address bits past bit 39 to be set for the addressing of

1121 NCR and commonly used in 345x/35xx/4100 class machines. It always

1127 config SCSI_NCR53C8XX_DEFAULT_TAGS
1128 int "default tagged command queue depth"
1129 depends on SCSI_ZALON || SCSI_NCR_Q720
1132 "Tagged command queuing" is a feature of SCSI-2 which improves
1133 performance: the host adapter can send several SCSI commands to a
1134 device's queue even if previous commands haven't finished yet.
1135 Because the device is intelligent, it can optimize its operations
1136 (like head positioning) based on its own request queue. Some SCSI
1137 devices don't implement this properly; if you want to disable this
1138 feature, enter 0 or 1 here (it doesn't matter which).
1140 The default value is 8 and should be supported by most hard disks.
1141 This value can be overridden from the boot command line using the
1142 'tags' option as follows (example):
1143 'ncr53c8xx=tags:4/t2t3q16/t0u2q10' will set default queue depth to
1144 4, set queue depth to 16 for target 2 and target 3 on controller 0
1145 and set queue depth to 10 for target 0 / lun 2 on controller 1.
1147 The normal answer therefore is to go with the default 8 and to use
1148 a boot command line option for devices that need to use a different
1149 command queue depth.
1151 There is no safe option other than using good SCSI devices.
1153 config SCSI_NCR53C8XX_MAX_TAGS
1154 int "maximum number of queued commands"
1155 depends on SCSI_ZALON || SCSI_NCR_Q720
1158 This option allows you to specify the maximum number of commands
1159 that can be queued to any device, when tagged command queuing is
1160 possible. The default value is 32. Minimum is 2, maximum is 64.
1161 Modern hard disks are able to support 64 tags and even more, but
1162 do not seem to be faster when more than 32 tags are being used.
1164 So, the normal answer here is to go with the default value 32 unless
1165 you are using very large hard disks with large cache (>= 1 MB) that
1166 are able to take advantage of more than 32 tagged commands.
1168 There is no safe option and the default answer is recommended.
1170 config SCSI_NCR53C8XX_SYNC
1171 int "synchronous transfers frequency in MHz"
1172 depends on SCSI_ZALON || SCSI_NCR_Q720
1175 The SCSI Parallel Interface-2 Standard defines 5 classes of transfer
1176 rates: FAST-5, FAST-10, FAST-20, FAST-40 and FAST-80. The numbers
1177 are respectively the maximum data transfer rates in mega-transfers
1178 per second for each class. For example, a FAST-20 Wide 16 device is
1179 able to transfer data at 20 million 16 bit packets per second for a
1180 total rate of 40 MB/s.
1182 You may specify 0 if you want to only use asynchronous data
1183 transfers. This is the safest and slowest option. Otherwise, specify
1184 a value between 5 and 80, depending on the capability of your SCSI
1185 controller. The higher the number, the faster the data transfer.
1186 Note that 80 should normally be ok since the driver decreases the
1187 value automatically according to the controller's capabilities.
1189 Your answer to this question is ignored for controllers with NVRAM,
1190 since the driver will get this information from the user set-up. It
1191 also can be overridden using a boot setup option, as follows
1192 (example): 'ncr53c8xx=sync:12' will allow the driver to negotiate
1193 for FAST-20 synchronous data transfer (20 mega-transfers per
1196 The normal answer therefore is not to go with the default but to
1197 select the maximum value 80 allowing the driver to use the maximum
1198 value supported by each controller. If this causes problems with
1199 your SCSI devices, you should come back and decrease the value.
1201 There is no safe option other than using good cabling, right
1202 terminations and SCSI conformant devices.

1206 depends on (SCSI_ZALON || SCSI_NCR_Q720) && SCSI_NCR53C8XX_DEFAULT_TAGS=0
1208 This option is only provided for safety if you suspect some SCSI
1209 device of yours to not support properly the target-disconnect
1210 feature. In that case, you would say Y here. In general however, to
1211 not allow targets to disconnect is not reasonable if there is more
1212 than 1 device on a SCSI bus. The normal answer therefore is N.

1337 This is support for the sym53c416 SCSI host adapter, the SCSI
1338 adapter that comes with some HP scanners. This driver requires that
1339 the sym53c416 is configured first using some sort of PnP
1340 configuration program (e.g. isapnp) or by a PnP aware BIOS. If you
1341 are using isapnp then you need to compile this driver as a module

1415 config SCSI_U14_34F_TAGGED_QUEUE
1416 bool "enable tagged command queueing"
1417 depends on SCSI_U14_34F
1419 This is a feature of SCSI-2 which improves performance: the host
1420 adapter can send several SCSI commands to a device's queue even if
1421 previous commands haven't finished yet.
1422 This is equivalent to the "u14-34f=tc:y" boot option.
1424 config SCSI_U14_34F_LINKED_COMMANDS
1425 bool "enable elevator sorting"
1426 depends on SCSI_U14_34F
1428 This option enables elevator sorting for all probed SCSI disks and
1429 CD-ROMs. It definitely reduces the average seek distance when doing
1430 random seeks, but this does not necessarily result in a noticeable
1431 performance improvement: your mileage may vary...
1432 This is equivalent to the "u14-34f=lc:y" boot option.
1434 config SCSI_U14_34F_MAX_TAGS
1435 int "maximum number of queued commands"
1436 depends on SCSI_U14_34F
1439 This specifies how many SCSI commands can be maximally queued for
1440 each probed SCSI device. You should reduce the default value of 8
1441 only if you have disks with buggy or limited tagged command support.
1442 Minimum is 2 and maximum is 14. This value is also the window size
1443 used by the elevator sorting option above. The effective value used
1444 by the driver for each probed SCSI device is reported at boot time.
1445 This is equivalent to the "u14-34f=mq:8" boot option.

1476 tristate "SCSI debugging host simulator"
1479 This is a host adapter simulator that can simulate multiple hosts
1480 each with multiple dummy SCSI devices (disks). It defaults to one
1481 host adapter with one dummy SCSI disk. Each dummy disk uses kernel
1482 RAM as storage (i.e. it is a ramdisk). To save space when multiple
1483 dummy disks are simulated, they share the same kernel RAM for
1484 their storage. See <http://www.torque.net/sg/sdebug.html> for more
1485 information. This driver is primarily of use to those testing the
1486 SCSI and block subsystems. If unsure, say N.

1505 On Power Macintoshes (and clones) where the MESH SCSI bus adaptor
1506 drives a bus which is entirely internal to the machine (such as the
1507 7500, 7600, 8500, etc.), the MESH is capable of synchronous
1508 operation at up to 10 MB/s. On machines where the SCSI bus
1509 controlled by the MESH can have external devices connected, it is
1510 usually rated at 5 MB/s. 5 is a safe value here unless you know the
1511 MESH SCSI bus is internal only; in that case you can say 10. Say 0
1512 to disable synchronous operation.

1521 depends on PPC32 && PPC_PMAC && SCSI
1523 On Power Macintoshes (and clones) with two SCSI buses, the external
1524 SCSI bus is usually controlled by a 53C94 SCSI bus adaptor. Older
1525 machines which only have one SCSI bus, such as the 7200, also use
1526 the 53C94. Say Y to include support for the 53C94.
