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.

62 If you want to use SCSI hard disks, Fibre Channel disks,
63 USB storage or the SCSI or parallel port version of
64 the IOMEGA ZIP drive, say Y and read the SCSI-HOWTO,
65 the Disk-HOWTO and the Multi-Disk-HOWTO, available from

73 Do not compile this driver as a module if your root file system
74 (the one containing the directory /) is located on a SCSI disk.
75 In this case, do not compile the driver for your SCSI host adapter

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

107 Please also have a look at the standard st docu, as most of it
108 applies to osst as well.

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

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

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

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

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

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

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

940 Some parallel ports are known to have excessive delays between

943 forces a small delay (1.0 usec to be exact) after changing the
944 control register to let things settle out. Enabling this option may
945 result in a big drop in performance but some very old parallel ports

1029 capable (875A, 895A, 896, 1010-33, 1010-66, 1000).
1031 When set to 0, the driver will program the chip to only perform
1032 32-bit DMA. When set to 1, the chip will be able to perform DMA
1033 to addresses up to 1TB. When set to 2, the driver supports the
1034 full 64-bit DMA address range, but can only address 16 segments
1035 of 4 GB each. This limits the total addressable range to 64 GB.
1037 Most machines with less than 4GB of memory should use a setting
1038 of 0 for best performance. If your machine has 4GB of memory
1039 or more, you should set this option to 1 (the default).
1041 The still experimental value 2 (64 bit DMA addressing with 16
1042 x 4GB segments limitation) can be used on systems that require
1043 PCI address bits past bit 39 to be set for the addressing of

1120 NCR and commonly used in 345x/35xx/4100 class machines. It always

1126 config SCSI_NCR53C8XX_DEFAULT_TAGS
1127 int "default tagged command queue depth"
1128 depends on SCSI_ZALON || SCSI_NCR_Q720
1131 "Tagged command queuing" is a feature of SCSI-2 which improves
1132 performance: the host adapter can send several SCSI commands to a
1133 device's queue even if previous commands haven't finished yet.
1134 Because the device is intelligent, it can optimize its operations
1135 (like head positioning) based on its own request queue. Some SCSI
1136 devices don't implement this properly; if you want to disable this
1137 feature, enter 0 or 1 here (it doesn't matter which).
1139 The default value is 8 and should be supported by most hard disks.
1140 This value can be overridden from the boot command line using the
1141 'tags' option as follows (example):
1142 'ncr53c8xx=tags:4/t2t3q16/t0u2q10' will set default queue depth to
1143 4, set queue depth to 16 for target 2 and target 3 on controller 0
1144 and set queue depth to 10 for target 0 / lun 2 on controller 1.
1146 The normal answer therefore is to go with the default 8 and to use
1147 a boot command line option for devices that need to use a different
1148 command queue depth.
1150 There is no safe option other than using good SCSI devices.
1152 config SCSI_NCR53C8XX_MAX_TAGS
1153 int "maximum number of queued commands"
1154 depends on SCSI_ZALON || SCSI_NCR_Q720
1157 This option allows you to specify the maximum number of commands
1158 that can be queued to any device, when tagged command queuing is
1159 possible. The default value is 32. Minimum is 2, maximum is 64.
1160 Modern hard disks are able to support 64 tags and even more, but
1161 do not seem to be faster when more than 32 tags are being used.
1163 So, the normal answer here is to go with the default value 32 unless
1164 you are using very large hard disks with large cache (>= 1 MB) that
1165 are able to take advantage of more than 32 tagged commands.
1167 There is no safe option and the default answer is recommended.
1169 config SCSI_NCR53C8XX_SYNC
1170 int "synchronous transfers frequency in MHz"
1171 depends on SCSI_ZALON || SCSI_NCR_Q720
1174 The SCSI Parallel Interface-2 Standard defines 5 classes of transfer
1175 rates: FAST-5, FAST-10, FAST-20, FAST-40 and FAST-80. The numbers
1176 are respectively the maximum data transfer rates in mega-transfers
1177 per second for each class. For example, a FAST-20 Wide 16 device is
1178 able to transfer data at 20 million 16 bit packets per second for a
1179 total rate of 40 MB/s.
1181 You may specify 0 if you want to only use asynchronous data
1182 transfers. This is the safest and slowest option. Otherwise, specify
1183 a value between 5 and 80, depending on the capability of your SCSI
1184 controller. The higher the number, the faster the data transfer.
1185 Note that 80 should normally be ok since the driver decreases the
1186 value automatically according to the controller's capabilities.
1188 Your answer to this question is ignored for controllers with NVRAM,
1189 since the driver will get this information from the user set-up. It
1190 also can be overridden using a boot setup option, as follows
1191 (example): 'ncr53c8xx=sync:12' will allow the driver to negotiate
1192 for FAST-20 synchronous data transfer (20 mega-transfers per
1195 The normal answer therefore is not to go with the default but to
1196 select the maximum value 80 allowing the driver to use the maximum
1197 value supported by each controller. If this causes problems with
1198 your SCSI devices, you should come back and decrease the value.
1200 There is no safe option other than using good cabling, right
1201 terminations and SCSI conformant devices.

1204 bool "not allow targets to disconnect"
1205 depends on (SCSI_ZALON || SCSI_NCR_Q720) && SCSI_NCR53C8XX_DEFAULT_TAGS=0
1207 This option is only provided for safety if you suspect some SCSI
1208 device of yours to not support properly the target-disconnect
1209 feature. In that case, you would say Y here. In general however, to
1210 not allow targets to disconnect is not reasonable if there is more
1211 than 1 device on a SCSI bus. The normal answer therefore is N.

1338 the sym53c416 is configured first using some sort of PnP
1339 configuration program (e.g. isapnp) or by a PnP aware BIOS. If you
1340 are using isapnp then you need to compile this driver as a module

1414 config SCSI_U14_34F_TAGGED_QUEUE
1415 bool "enable tagged command queueing"
1416 depends on SCSI_U14_34F
1418 This is a feature of SCSI-2 which improves performance: the host
1419 adapter can send several SCSI commands to a device's queue even if
1420 previous commands haven't finished yet.
1421 This is equivalent to the "u14-34f=tc:y" boot option.
1423 config SCSI_U14_34F_LINKED_COMMANDS
1424 bool "enable elevator sorting"
1425 depends on SCSI_U14_34F
1427 This option enables elevator sorting for all probed SCSI disks and
1428 CD-ROMs. It definitely reduces the average seek distance when doing
1429 random seeks, but this does not necessarily result in a noticeable
1430 performance improvement: your mileage may vary...
1431 This is equivalent to the "u14-34f=lc:y" boot option.
1433 config SCSI_U14_34F_MAX_TAGS
1434 int "maximum number of queued commands"
1435 depends on SCSI_U14_34F
1438 This specifies how many SCSI commands can be maximally queued for
1439 each probed SCSI device. You should reduce the default value of 8
1440 only if you have disks with buggy or limited tagged command support.
1441 Minimum is 2 and maximum is 14. This value is also the window size
1442 used by the elevator sorting option above. The effective value used
1443 by the driver for each probed SCSI device is reported at boot time.
1444 This is equivalent to the "u14-34f=mq:8" boot option.

1475 tristate "SCSI debugging host simulator"
1478 This is a host adapter simulator that can simulate multiple hosts
1479 each with multiple dummy SCSI devices (disks). It defaults to one
1480 host adapter with one dummy SCSI disk. Each dummy disk uses kernel
1481 RAM as storage (i.e. it is a ramdisk). To save space when multiple
1482 dummy disks are simulated, they share the same kernel RAM for
1483 their storage. See <http://www.torque.net/sg/sdebug.html> for more
1484 information. This driver is primarily of use to those testing the
1485 SCSI and block subsystems. If unsure, say N.

1504 On Power Macintoshes (and clones) where the MESH SCSI bus adaptor
1505 drives a bus which is entirely internal to the machine (such as the
1506 7500, 7600, 8500, etc.), the MESH is capable of synchronous
1507 operation at up to 10 MB/s. On machines where the SCSI bus
1508 controlled by the MESH can have external devices connected, it is
1509 usually rated at 5 MB/s. 5 is a safe value here unless you know the
1510 MESH SCSI bus is internal only; in that case you can say 10. Say 0
1511 to disable synchronous operation.
