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

40 This option enables support for the various files in

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

130 If you want to use SCSI scanners, synthesizers or CD-writers or just
131 about anything having "SCSI" in its name other than hard disks,
132 CD-ROMs or tapes, say Y here. These won't be supported by the kernel
133 directly, so you need some additional software which knows how to
134 talk to these devices using the SCSI protocol:
136 For scanners, look at SANE (<http://www.mostang.com/sane/>). For CD
137 writer software look at Cdrtools
138 (<http://www.fokus.gmd.de/research/cc/glone/employees/joerg.schilling/private/cdrecord.html>)
139 and for burning a "disk at once": CDRDAO
140 (<http://cdrdao.sourceforge.net/>). Cdparanoia is a high
141 quality digital reader of audio CDs (<http://www.xiph.org/paranoia/>).
142 For other devices, it's possible that you'll have to write the
143 driver software yourself. Please read the file

155 This is a driver for SCSI media changers. Most common devices are
156 tape libraries and MOD/CDROM jukeboxes. *Real* jukeboxes, you
157 don't need this for those tiny 6-slot cdrom changers. Media
158 changers are listed as "Type: Medium Changer" in /proc/scsi/scsi.

173 bool "Probe all LUNs on each SCSI device"
176 If you have a SCSI device that supports more than one LUN (Logical
177 Unit Number), e.g. a CD jukebox, and only one LUN is detected, you
178 can say Y here to force the SCSI driver to probe for multiple LUNs.
179 A SCSI device with multiple LUNs acts logically like multiple SCSI
180 devices. The vast majority of SCSI devices have only one LUN, and
181 so most people can say N here. The max_luns boot/module parameter
182 allows to override this setting.
184 config SCSI_CONSTANTS
185 bool "Verbose SCSI error reporting (kernel size +=12K)"

189 understand if you say Y here; it will enlarge your kernel by about
190 12 KB. If in doubt, say Y.
193 bool "SCSI logging facility"
196 This turns on a logging facility that can be used to debug a number
197 of SCSI related problems.
199 If you say Y here, no logging output will appear by default, but you
200 can enable logging by saying Y to "/proc file system support" and
201 "Sysctl support" below and executing the command
203 echo "scsi log token [level]" > /proc/scsi/scsi
205 at boot time after the /proc file system has been mounted.
207 There are a number of things that can be used for 'token' (you can
208 find them in the source: <file:drivers/scsi/scsi.c>), and this
209 allows you to select the types of information you want, and the
210 level allows you to select the level of verbosity.
212 If you say N here, it may be harder to track down some types of SCSI
213 problems. If you say Y here your kernel will be somewhat larger, but
214 there should be no noticeable performance impact as long as you have

666 on boards using PIO. Most boards such as the Trantor T130 fit this
667 category, along with a large number of ISA 8bit controllers shipped
668 for free with SCSI scanners. If you have a PAS16, T128 or DMX3191
669 you should select the specific driver for that card rather than
670 generic 5380 support.
672 It is explained in section 3.8 of the SCSI-HOWTO, available from
673 <http://www.tldp.org/docs.html#howto>. If it doesn't work out

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

707 tristate "IBMMCA SCSI support"
708 depends on MCA_LEGACY && SCSI
710 This is support for the IBM SCSI adapter found in many of the PS/2
711 series computers. These machines have an MCA bus, so you need to
712 answer Y to "MCA support" as well and read
713 <file:Documentation/mca.txt>.
715 If the adapter isn't found during boot (a common problem for models
716 56, 57, 76, and 77) you'll need to use the 'ibmmcascsi=<pun>' kernel
717 option, where <pun> is the id of the SCSI subsystem (usually 7, but
718 if that doesn't work check your reference diskette). Owners of
719 model 95 with a LED-matrix-display can in addition activate some
720 activity info like under OS/2, but more informative, by setting
721 'ibmmcascsi=display' as an additional kernel parameter. Try "man
722 bootparam" or see the documentation of your boot loader about how to
723 pass options to the kernel.

728 config IBMMCA_SCSI_ORDER_STANDARD
729 bool "Standard SCSI-order"
730 depends on SCSI_IBMMCA
732 In the PC-world and in most modern SCSI-BIOS-setups, SCSI-hard disks
733 are assigned to the drive letters, starting with the lowest SCSI-id
734 (physical number -- pun) to be drive C:, as seen from DOS and
735 similar operating systems. When looking into papers describing the
736 ANSI-SCSI-standard, this assignment of drives appears to be wrong.
737 The SCSI-standard follows a hardware-hierarchy which says that id 7
738 has the highest priority and id 0 the lowest. Therefore, the host
739 adapters are still today everywhere placed as SCSI-id 7 by default.
740 In the SCSI-standard, the drive letters express the priority of the
741 disk. C: should be the hard disk, or a partition on it, with the
742 highest priority. This must therefore be the disk with the highest
743 SCSI-id (e.g. 6) and not the one with the lowest! IBM-BIOS kept the
744 original definition of the SCSI-standard as also industrial- and
745 process-control-machines, like VME-CPUs running under realtime-OSes
746 (e.g. LynxOS, OS9) do.
748 If you like to run Linux on your MCA-machine with the same
749 assignment of hard disks as seen from e.g. DOS or OS/2 on your
750 machine, which is in addition conformant to the SCSI-standard, you
751 must say Y here. This is also necessary for MCA-Linux users who want
752 to keep downward compatibility to older releases of the
753 IBM-MCA-SCSI-driver (older than driver-release 2.00 and older than
756 If you like to have the lowest SCSI-id assigned as drive C:, as
757 modern SCSI-BIOSes do, which does not conform to the standard, but
758 is widespread and common in the PC-world of today, you must say N
759 here. If unsure, say Y.

765 By default, SCSI-devices are reset when the machine is powered on.
766 However, some devices exist, like special-control-devices,
767 SCSI-CNC-machines, SCSI-printer or scanners of older type, that do
768 not reset when switched on. If you say Y here, each device connected
769 to your SCSI-bus will be issued a reset-command after it has been
770 probed, while the kernel is booting. This may cause problems with
771 more modern devices, like hard disks, which do not appreciate these
772 reset commands, and can cause your system to hang. So say Y only if

893 Some parallel ports are known to have excessive delays between
894 changing the parallel port control register and good data being

896 forces a small delay (1.0 usec to be exact) after changing the
897 control register to let things settle out. Enabling this option may
898 result in a big drop in performance but some very old parallel ports
899 (found in 386 vintage machines) will not work properly.

968 capable (875A, 895A, 896, 1010-33, 1010-66, 1000).
970 When set to 0, the driver will program the chip to only perform
971 32-bit DMA. When set to 1, the chip will be able to perform DMA
972 to addresses up to 1TB. When set to 2, the driver supports the
973 full 64-bit DMA address range, but can only address 16 segments
974 of 4 GB each. This limits the total addressable range to 64 GB.
976 Most machines with less than 4GB of memory should use a setting
977 of 0 for best performance. If your machine has 4GB of memory
978 or more, you should set this option to 1 (the default).
980 The still experimental value 2 (64 bit DMA addressing with 16
981 x 4GB segments limitation) can be used on systems that require
982 PCI address bits past bit 39 to be set for the addressing of
983 memory using PCI DAC cycles.

990 This is the default value of the command queue depth the

997 int "Maximum number of queued commands"
998 depends on SCSI_SYM53C8XX_2
1001 This option allows you to specify the maximum number of commands
1002 that can be queued to any device, when tagged command queuing is
1003 possible. The driver supports up to 256 queued commands per device.
1004 This value is used as a compiled-in hard limit.

1056 This is a driver for the MicroChannel Quad 720 card produced by
1057 NCR and commonly used in 345x/35xx/4100 class machines. It always

1061 you do not have this SCSI card, so say N.
1063 config SCSI_NCR53C8XX_DEFAULT_TAGS
1064 int "default tagged command queue depth"
1065 depends on SCSI_ZALON || SCSI_NCR_Q720
1068 "Tagged command queuing" is a feature of SCSI-2 which improves
1069 performance: the host adapter can send several SCSI commands to a
1070 device's queue even if previous commands haven't finished yet.
1071 Because the device is intelligent, it can optimize its operations
1072 (like head positioning) based on its own request queue. Some SCSI
1073 devices don't implement this properly; if you want to disable this
1074 feature, enter 0 or 1 here (it doesn't matter which).
1076 The default value is 8 and should be supported by most hard disks.
1077 This value can be overridden from the boot command line using the
1078 'tags' option as follows (example):
1079 'ncr53c8xx=tags:4/t2t3q16/t0u2q10' will set default queue depth to
1080 4, set queue depth to 16 for target 2 and target 3 on controller 0
1081 and set queue depth to 10 for target 0 / lun 2 on controller 1.
1083 The normal answer therefore is to go with the default 8 and to use
1084 a boot command line option for devices that need to use a different
1085 command queue depth.
1087 There is no safe option other than using good SCSI devices.
1089 config SCSI_NCR53C8XX_MAX_TAGS
1090 int "maximum number of queued commands"
1091 depends on SCSI_ZALON || SCSI_NCR_Q720
1094 This option allows you to specify the maximum number of commands
1095 that can be queued to any device, when tagged command queuing is
1096 possible. The default value is 32. Minimum is 2, maximum is 64.
1097 Modern hard disks are able to support 64 tags and even more, but
1098 do not seem to be faster when more than 32 tags are being used.
1100 So, the normal answer here is to go with the default value 32 unless
1101 you are using very large hard disks with large cache (>= 1 MB) that
1102 are able to take advantage of more than 32 tagged commands.
1104 There is no safe option and the default answer is recommended.
1106 config SCSI_NCR53C8XX_SYNC
1107 int "synchronous transfers frequency in MHz"
1108 depends on SCSI_ZALON || SCSI_NCR_Q720
1111 The SCSI Parallel Interface-2 Standard defines 5 classes of transfer
1112 rates: FAST-5, FAST-10, FAST-20, FAST-40 and FAST-80. The numbers
1113 are respectively the maximum data transfer rates in mega-transfers
1114 per second for each class. For example, a FAST-20 Wide 16 device is
1115 able to transfer data at 20 million 16 bit packets per second for a
1116 total rate of 40 MB/s.
1118 You may specify 0 if you want to only use asynchronous data
1119 transfers. This is the safest and slowest option. Otherwise, specify
1120 a value between 5 and 80, depending on the capability of your SCSI
1121 controller. The higher the number, the faster the data transfer.
1122 Note that 80 should normally be ok since the driver decreases the
1123 value automatically according to the controller's capabilities.
1125 Your answer to this question is ignored for controllers with NVRAM,
1126 since the driver will get this information from the user set-up. It
1127 also can be overridden using a boot setup option, as follows
1128 (example): 'ncr53c8xx=sync:12' will allow the driver to negotiate
1129 for FAST-20 synchronous data transfer (20 mega-transfers per
1132 The normal answer therefore is not to go with the default but to
1133 select the maximum value 80 allowing the driver to use the maximum
1134 value supported by each controller. If this causes problems with
1135 your SCSI devices, you should come back and decrease the value.
1137 There is no safe option other than using good cabling, right
1138 terminations and SCSI conformant devices.
1140 config SCSI_NCR53C8XX_PROFILE
1141 bool "enable profiling"
1142 depends on SCSI_ZALON || SCSI_NCR_Q720
1144 This option allows you to enable profiling information gathering.
1145 These statistics are not very accurate due to the low frequency
1146 of the kernel clock (100 Hz on i386) and have performance impact
1147 on systems that use very fast devices.
1149 The normal answer therefore is N.
1151 config SCSI_NCR53C8XX_NO_DISCONNECT
1152 bool "not allow targets to disconnect"
1153 depends on (SCSI_ZALON || SCSI_NCR_Q720) && SCSI_NCR53C8XX_DEFAULT_TAGS=0
1155 This option is only provided for safety if you suspect some SCSI
1156 device of yours to not support properly the target-disconnect
1157 feature. In that case, you would say Y here. In general however, to
1158 not allow targets to disconnect is not reasonable if there is more
1159 than 1 device on a SCSI bus. The normal answer therefore is N.

1290 the sym53c416 is configured first using some sort of PnP
1291 configuration program (e.g. isapnp) or by a PnP aware BIOS. If you
1292 are using isapnp then you need to compile this driver as a module

1366 config SCSI_U14_34F_TAGGED_QUEUE
1367 bool "enable tagged command queueing"
1368 depends on SCSI_U14_34F
1370 This is a feature of SCSI-2 which improves performance: the host
1371 adapter can send several SCSI commands to a device's queue even if
1372 previous commands haven't finished yet.
1373 This is equivalent to the "u14-34f=tc:y" boot option.
1375 config SCSI_U14_34F_LINKED_COMMANDS
1376 bool "enable elevator sorting"
1377 depends on SCSI_U14_34F
1379 This option enables elevator sorting for all probed SCSI disks and
1380 CD-ROMs. It definitely reduces the average seek distance when doing
1381 random seeks, but this does not necessarily result in a noticeable
1382 performance improvement: your mileage may vary...
1383 This is equivalent to the "u14-34f=lc:y" boot option.
1385 config SCSI_U14_34F_MAX_TAGS
1386 int "maximum number of queued commands"
1387 depends on SCSI_U14_34F
1390 This specifies how many SCSI commands can be maximally queued for
1391 each probed SCSI device. You should reduce the default value of 8
1392 only if you have disks with buggy or limited tagged command support.
1393 Minimum is 2 and maximum is 14. This value is also the window size
1394 used by the elevator sorting option above. The effective value used
1395 by the driver for each probed SCSI device is reported at boot time.

1427 tristate "SCSI debugging host simulator"
1430 This is a host adapter simulator that can simulate multiple hosts
1431 each with multiple dummy SCSI devices (disks). It defaults to one
1432 host adapter with one dummy SCSI disk. Each dummy disk uses kernel
1433 RAM as storage (i.e. it is a ramdisk). To save space when multiple
1434 dummy disks are simulated, they share the same kernel RAM for
1435 their storage. See <http://www.torque.net/sg/sdebug.html> for more
1436 information. This driver is primarily of use to those testing the

1456 On Power Macintoshes (and clones) where the MESH SCSI bus adaptor
1457 drives a bus which is entirely internal to the machine (such as the
1458 7500, 7600, 8500, etc.), the MESH is capable of synchronous
1459 operation at up to 10 MB/s. On machines where the SCSI bus
1460 controlled by the MESH can have external devices connected, it is
1461 usually rated at 5 MB/s. 5 is a safe value here unless you know the
1462 MESH SCSI bus is internal only; in that case you can say 10. Say 0
1463 to disable synchronous operation.
