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.

39 depends on SCSI && PROC_FS
42 This option enables support for the various files in

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

124 required to support multisession CDs with old NEC/TOSHIBA cdrom
125 drives (and HP Writers). If you have such a drive and get the first
126 session only, try saying Y here; everybody else says N.
129 tristate "SCSI generic support"
132 If you want to use SCSI scanners, synthesizers or CD-writers or just
133 about anything having "SCSI" in its name other than hard disks,
134 CD-ROMs or tapes, say Y here. These won't be supported by the kernel
135 directly, so you need some additional software which knows how to
136 talk to these devices using the SCSI protocol:
138 For scanners, look at SANE (<http://www.mostang.com/sane/>). For CD
139 writer software look at Cdrtools
140 (<http://www.fokus.gmd.de/research/cc/glone/employees/joerg.schilling/private/cdrecord.html>)
141 and for burning a "disk at once": CDRDAO
142 (<http://cdrdao.sourceforge.net/>). Cdparanoia is a high
143 quality digital reader of audio CDs (<http://www.xiph.org/paranoia/>).
144 For other devices, it's possible that you'll have to write the
145 driver software yourself. Please read the file
146 <file:Documentation/scsi/scsi-generic.txt> for more information.

154 tristate "SCSI media changer support"
157 This is a driver for SCSI media changers. Most common devices are
158 tape libraries and MOD/CDROM jukeboxes. *Real* jukeboxes, you
159 don't need this for those tiny 6-slot cdrom changers. Media
160 changers are listed as "Type: Medium Changer" in /proc/scsi/scsi.
161 If you have such hardware and want to use it with linux, say Y
162 here. Check <file:Documentation/scsi-changer.txt> for details.

171 comment "Some SCSI devices (e.g. CD jukebox) support multiple LUNs"
174 config SCSI_MULTI_LUN
175 bool "Probe all LUNs on each SCSI device"
178 If you have a SCSI device that supports more than one LUN (Logical
179 Unit Number), e.g. a CD jukebox, and only one LUN is detected, you
180 can say Y here to force the SCSI driver to probe for multiple LUNs.
181 A SCSI device with multiple LUNs acts logically like multiple SCSI
182 devices. The vast majority of SCSI devices have only one LUN, and
183 so most people can say N here. The max_luns boot/module parameter
184 allows to override this setting.
186 config SCSI_CONSTANTS
187 bool "Verbose SCSI error reporting (kernel size +=12K)"
190 The error messages regarding your SCSI hardware will be easier to
191 understand if you say Y here; it will enlarge your kernel by about
192 12 KB. If in doubt, say Y.
195 bool "SCSI logging facility"
198 This turns on a logging facility that can be used to debug a number
199 of SCSI related problems.
201 If you say Y here, no logging output will appear by default, but you
202 can enable logging by saying Y to "/proc file system support" and
203 "Sysctl support" below and executing the command
205 echo "scsi log token [level]" > /proc/scsi/scsi
207 at boot time after the /proc file system has been mounted.
209 There are a number of things that can be used for 'token' (you can
210 find them in the source: <file:drivers/scsi/scsi.c>), and this
211 allows you to select the types of information you want, and the
212 level allows you to select the level of verbosity.
214 If you say N here, it may be harder to track down some types of SCSI
215 problems. If you say Y here your kernel will be somewhat larger, but
216 there should be no noticeable performance impact as long as you have
219 config SCSI_SCAN_ASYNC
220 bool "Asynchronous SCSI scanning"
223 The SCSI subsystem can probe for devices while the rest of the
224 system continues booting, and even probe devices on different
225 busses in parallel, leading to a significant speed-up.
226 If you have built SCSI as modules, enabling this option can
227 be a problem as the devices may not have been found by the
228 time your system expects them to have been. You can load the
229 scsi_wait_scan module to ensure that all scans have completed.
230 If you build your SCSI drivers into the kernel, then everything
231 will work fine if you say Y here.
233 You can override this choice by specifying scsi_mod.scan="sync"
234 or "async" on the kernel's command line.

669 Formerly called GDT SCSI Disk Array Controller Support.
671 This is a driver for RAID/SCSI Disk Array Controllers (EISA/ISA/PCI)
672 manufactured by Intel Corporation/ICP vortex GmbH. It is documented
673 in the kernel source in <file:drivers/scsi/gdth.c> and

680 tristate "Generic NCR5380/53c400 SCSI PIO support"
681 depends on ISA && SCSI
682 select SCSI_SPI_ATTRS
684 This is a driver for the old NCR 53c80 series of SCSI controllers
685 on boards using PIO. Most boards such as the Trantor T130 fit this
686 category, along with a large number of ISA 8bit controllers shipped
687 for free with SCSI scanners. If you have a PAS16, T128 or DMX3191
688 you should select the specific driver for that card rather than
689 generic 5380 support.
691 It is explained in section 3.8 of the SCSI-HOWTO, available from
692 <http://www.tldp.org/docs.html#howto>. If it doesn't work out
693 of the box, you may have to change some settings in

705 on boards using memory mapped I/O.
706 It is explained in section 3.8 of the SCSI-HOWTO, available from

715 bool "Enable NCR53c400 extensions"
716 depends on SCSI_GENERIC_NCR5380
718 This enables certain optimizations for the NCR53c400 SCSI cards.
719 You might as well try it out. Note that this driver will only probe
720 for the Trantor T130B in its default configuration; you might have
721 to pass a command line option to the kernel at boot time if it does
722 not detect your card. See the file
723 <file:Documentation/scsi/g_NCR5380.txt> for details.
726 tristate "IBMMCA SCSI support"
727 depends on MCA_LEGACY && SCSI
729 This is support for the IBM SCSI adapter found in many of the PS/2
730 series computers. These machines have an MCA bus, so you need to
731 answer Y to "MCA support" as well and read
732 <file:Documentation/mca.txt>.
734 If the adapter isn't found during boot (a common problem for models
735 56, 57, 76, and 77) you'll need to use the 'ibmmcascsi=<pun>' kernel
736 option, where <pun> is the id of the SCSI subsystem (usually 7, but
737 if that doesn't work check your reference diskette). Owners of
738 model 95 with a LED-matrix-display can in addition activate some
739 activity info like under OS/2, but more informative, by setting
740 'ibmmcascsi=display' as an additional kernel parameter. Try "man
741 bootparam" or see the documentation of your boot loader about how to
742 pass options to the kernel.
744 To compile this driver as a module, choose M here: the
745 module will be called ibmmca.
747 config IBMMCA_SCSI_ORDER_STANDARD
748 bool "Standard SCSI-order"
749 depends on SCSI_IBMMCA
751 In the PC-world and in most modern SCSI-BIOS-setups, SCSI-hard disks
752 are assigned to the drive letters, starting with the lowest SCSI-id
753 (physical number -- pun) to be drive C:, as seen from DOS and
754 similar operating systems. When looking into papers describing the
755 ANSI-SCSI-standard, this assignment of drives appears to be wrong.
756 The SCSI-standard follows a hardware-hierarchy which says that id 7
757 has the highest priority and id 0 the lowest. Therefore, the host
758 adapters are still today everywhere placed as SCSI-id 7 by default.
759 In the SCSI-standard, the drive letters express the priority of the
760 disk. C: should be the hard disk, or a partition on it, with the
761 highest priority. This must therefore be the disk with the highest
762 SCSI-id (e.g. 6) and not the one with the lowest! IBM-BIOS kept the
763 original definition of the SCSI-standard as also industrial- and
764 process-control-machines, like VME-CPUs running under realtime-OSes
765 (e.g. LynxOS, OS9) do.
767 If you like to run Linux on your MCA-machine with the same
768 assignment of hard disks as seen from e.g. DOS or OS/2 on your
769 machine, which is in addition conformant to the SCSI-standard, you
770 must say Y here. This is also necessary for MCA-Linux users who want
771 to keep downward compatibility to older releases of the
772 IBM-MCA-SCSI-driver (older than driver-release 2.00 and older than
775 If you like to have the lowest SCSI-id assigned as drive C:, as
776 modern SCSI-BIOSes do, which does not conform to the standard, but
777 is widespread and common in the PC-world of today, you must say N
778 here. If unsure, say Y.
780 config IBMMCA_SCSI_DEV_RESET
781 bool "Reset SCSI-devices at boottime"
782 depends on SCSI_IBMMCA
784 By default, SCSI-devices are reset when the machine is powered on.
785 However, some devices exist, like special-control-devices,
786 SCSI-CNC-machines, SCSI-printer or scanners of older type, that do
787 not reset when switched on. If you say Y here, each device connected
788 to your SCSI-bus will be issued a reset-command after it has been
789 probed, while the kernel is booting. This may cause problems with
790 more modern devices, like hard disks, which do not appreciate these
791 reset commands, and can cause your system to hang. So say Y only if
792 you know that one of your older devices needs it; N is the safe

841 depends on SCSI && PARPORT_PC
843 This driver supports older versions of IOMEGA's parallel port ZIP
844 drive (a 100 MB removable media device).
846 Note that you can say N here if you have the SCSI version of the ZIP
847 drive: it will be supported automatically if you said Y to the
848 generic "SCSI disk support", above.
850 If you have the ZIP Plus drive or a more recent parallel port ZIP
851 drive (if the supplied cable with the drive is labeled "AutoDetect")

895 depends on SCSI_PPA || SCSI_IMM
897 EPP (Enhanced Parallel Port) is a standard for parallel ports which
898 allows them to act as expansion buses that can handle up to 64
901 Some parallel port chipsets are slower than their motherboard, and
902 so we have to control the state of the chipset's FIFO queue every
903 now and then to avoid data loss. This will be done if you say Y

908 config SCSI_IZIP_SLOW_CTR
909 bool "ppa/imm option - Assume slow parport control register"
910 depends on SCSI_PPA || SCSI_IMM
912 Some parallel ports are known to have excessive delays between
913 changing the parallel port control register and good data being
914 available on the parallel port data/status register. This option
915 forces a small delay (1.0 usec to be exact) after changing the
916 control register to let things settle out. Enabling this option may
917 result in a big drop in performance but some very old parallel ports
918 (found in 386 vintage machines) will not work properly.
920 Generally, saying N is fine.

939 This is a driver for the MicroChannel Dual 700 card produced by
940 NCR and commonly used in 345x/35xx/4100 class machines. It always
941 tries to negotiate sync and uses tag command queueing.
943 Unless you have an NCR manufactured machine, the chances are that
944 you do not have this SCSI card, so say N.

969 depends on PCI && SCSI
970 select SCSI_SPI_ATTRS
972 This driver supports the whole NCR53C8XX/SYM53C8XX family of
973 PCI-SCSI controllers. It also supports the subset of LSI53C10XX
974 Ultra-160 controllers that are based on the SYM53C8XX SCRIPTS
975 language. It does not support LSI53C10XX Ultra-320 PCI-X SCSI
976 controllers; you need to use the Fusion MPT driver for that.

981 config SCSI_SYM53C8XX_DMA_ADDRESSING_MODE
982 int "DMA addressing mode"
983 depends on SCSI_SYM53C8XX_2
986 This option only applies to PCI-SCSI chips that are PCI DAC
987 capable (875A, 895A, 896, 1010-33, 1010-66, 1000).
989 When set to 0, the driver will program the chip to only perform
990 32-bit DMA. When set to 1, the chip will be able to perform DMA
991 to addresses up to 1TB. When set to 2, the driver supports the
992 full 64-bit DMA address range, but can only address 16 segments
993 of 4 GB each. This limits the total addressable range to 64 GB.
995 Most machines with less than 4GB of memory should use a setting
996 of 0 for best performance. If your machine has 4GB of memory
997 or more, you should set this option to 1 (the default).
999 The still experimental value 2 (64 bit DMA addressing with 16
1000 x 4GB segments limitation) can be used on systems that require
1001 PCI address bits past bit 39 to be set for the addressing of
1002 memory using PCI DAC cycles.
1004 config SCSI_SYM53C8XX_DEFAULT_TAGS
1005 int "Default tagged command queue depth"
1006 depends on SCSI_SYM53C8XX_2
1009 This is the default value of the command queue depth the
1010 driver will announce to the generic SCSI layer for devices
1011 that support tagged command queueing. This value can be changed
1012 from the boot command line. This is a soft limit that cannot
1013 exceed CONFIG_SCSI_SYM53C8XX_MAX_TAGS.
1015 config SCSI_SYM53C8XX_MAX_TAGS
1016 int "Maximum number of queued commands"
1017 depends on SCSI_SYM53C8XX_2
1020 This option allows you to specify the maximum number of commands
1021 that can be queued to any device, when tagged command queuing is
1022 possible. The driver supports up to 256 queued commands per device.
1023 This value is used as a compiled-in hard limit.
1025 config SCSI_SYM53C8XX_MMIO
1026 bool "Use memory mapped IO"
1027 depends on SCSI_SYM53C8XX_2
1030 Memory mapped IO is faster than Port IO. Most people should
1031 answer Y here, but some machines may have problems. If you have
1032 to answer N here, please report the problem to the maintainer.
1035 tristate "IBM Power Linux RAID adapter support"
1036 depends on PCI && SCSI && ATA
1039 This driver supports the IBM Power Linux family RAID adapters.
1040 This includes IBM pSeries 5712, 5703, 5709, and 570A, as well
1041 as IBM iSeries 5702, 5703, 5709, and 570A.
1043 config SCSI_IPR_TRACE
1044 bool "enable driver internal trace"
1048 If you say Y here, the driver will trace all commands issued
1049 to the adapter. Performance impact is minimal. Trace can be
1050 dumped using /sys/bus/class/scsi_host/hostXX/trace.
1052 config SCSI_IPR_DUMP
1053 bool "enable adapter dump support"
1057 If you say Y here, the driver will support adapter crash dump.
1058 If you enable this support, the iprdump daemon can be used
1059 to capture adapter failure analysis information.
1062 tristate "Zalon SCSI support"
1063 depends on GSC && SCSI
1064 select SCSI_SPI_ATTRS
1066 The Zalon is a GSC/HSC bus interface chip that sits between the
1067 PA-RISC processor and the NCR 53c720 SCSI controller on C100,
1068 C110, J200, J210 and some D, K & R-class machines. It's also
1069 used on the add-in Bluefish, Barracuda & Shrike SCSI cards.
1070 Say Y here if you have one of these machines or cards.
1072 config SCSI_NCR_Q720
1073 tristate "NCR Quad 720 MCA SCSI support"
1074 depends on MCA && SCSI
1075 select SCSI_SPI_ATTRS
1077 This is a driver for the MicroChannel Quad 720 card produced by
1078 NCR and commonly used in 345x/35xx/4100 class machines. It always
1079 tries to negotiate sync and uses tag command queueing.
1081 Unless you have an NCR manufactured machine, the chances are that
1082 you do not have this SCSI card, so say N.
1084 config SCSI_NCR53C8XX_DEFAULT_TAGS
1085 int "default tagged command queue depth"
1086 depends on SCSI_ZALON || SCSI_NCR_Q720
1089 "Tagged command queuing" is a feature of SCSI-2 which improves
1090 performance: the host adapter can send several SCSI commands to a
1091 device's queue even if previous commands haven't finished yet.
1092 Because the device is intelligent, it can optimize its operations
1093 (like head positioning) based on its own request queue. Some SCSI
1094 devices don't implement this properly; if you want to disable this
1095 feature, enter 0 or 1 here (it doesn't matter which).
1097 The default value is 8 and should be supported by most hard disks.
1098 This value can be overridden from the boot command line using the
1099 'tags' option as follows (example):
1100 'ncr53c8xx=tags:4/t2t3q16/t0u2q10' will set default queue depth to
1101 4, set queue depth to 16 for target 2 and target 3 on controller 0
1102 and set queue depth to 10 for target 0 / lun 2 on controller 1.
1104 The normal answer therefore is to go with the default 8 and to use
1105 a boot command line option for devices that need to use a different
1106 command queue depth.
1108 There is no safe option other than using good SCSI devices.
1110 config SCSI_NCR53C8XX_MAX_TAGS
1111 int "maximum number of queued commands"
1112 depends on SCSI_ZALON || SCSI_NCR_Q720
1115 This option allows you to specify the maximum number of commands
1116 that can be queued to any device, when tagged command queuing is
1117 possible. The default value is 32. Minimum is 2, maximum is 64.
1118 Modern hard disks are able to support 64 tags and even more, but
1119 do not seem to be faster when more than 32 tags are being used.
1121 So, the normal answer here is to go with the default value 32 unless
1122 you are using very large hard disks with large cache (>= 1 MB) that
1123 are able to take advantage of more than 32 tagged commands.
1125 There is no safe option and the default answer is recommended.
1127 config SCSI_NCR53C8XX_SYNC
1128 int "synchronous transfers frequency in MHz"
1129 depends on SCSI_ZALON || SCSI_NCR_Q720
1132 The SCSI Parallel Interface-2 Standard defines 5 classes of transfer
1133 rates: FAST-5, FAST-10, FAST-20, FAST-40 and FAST-80. The numbers
1134 are respectively the maximum data transfer rates in mega-transfers
1135 per second for each class. For example, a FAST-20 Wide 16 device is
1136 able to transfer data at 20 million 16 bit packets per second for a
1137 total rate of 40 MB/s.
1139 You may specify 0 if you want to only use asynchronous data
1140 transfers. This is the safest and slowest option. Otherwise, specify
1141 a value between 5 and 80, depending on the capability of your SCSI
1142 controller. The higher the number, the faster the data transfer.
1143 Note that 80 should normally be ok since the driver decreases the
1144 value automatically according to the controller's capabilities.
1146 Your answer to this question is ignored for controllers with NVRAM,
1147 since the driver will get this information from the user set-up. It
1148 also can be overridden using a boot setup option, as follows
1149 (example): 'ncr53c8xx=sync:12' will allow the driver to negotiate
1150 for FAST-20 synchronous data transfer (20 mega-transfers per
1153 The normal answer therefore is not to go with the default but to
1154 select the maximum value 80 allowing the driver to use the maximum
1155 value supported by each controller. If this causes problems with
1156 your SCSI devices, you should come back and decrease the value.
1158 There is no safe option other than using good cabling, right
1159 terminations and SCSI conformant devices.
1161 config SCSI_NCR53C8XX_PROFILE
1162 bool "enable profiling"
1163 depends on SCSI_ZALON || SCSI_NCR_Q720
1165 This option allows you to enable profiling information gathering.
1166 These statistics are not very accurate due to the low frequency
1167 of the kernel clock (100 Hz on i386) and have performance impact
1168 on systems that use very fast devices.
1170 The normal answer therefore is N.
1172 config SCSI_NCR53C8XX_NO_DISCONNECT
1173 bool "not allow targets to disconnect"
1174 depends on (SCSI_ZALON || SCSI_NCR_Q720) && SCSI_NCR53C8XX_DEFAULT_TAGS=0
1176 This option is only provided for safety if you suspect some SCSI
1177 device of yours to not support properly the target-disconnect
1178 feature. In that case, you would say Y here. In general however, to
1179 not allow targets to disconnect is not reasonable if there is more
1180 than 1 device on a SCSI bus. The normal answer therefore is N.

1312 the sym53c416 is configured first using some sort of PnP
1313 configuration program (e.g. isapnp) or by a PnP aware BIOS. If you
1314 are using isapnp then you need to compile this driver as a module

1388 config SCSI_U14_34F_TAGGED_QUEUE
1389 bool "enable tagged command queueing"
1390 depends on SCSI_U14_34F
1392 This is a feature of SCSI-2 which improves performance: the host
1393 adapter can send several SCSI commands to a device's queue even if
1394 previous commands haven't finished yet.
1395 This is equivalent to the "u14-34f=tc:y" boot option.
1397 config SCSI_U14_34F_LINKED_COMMANDS
1398 bool "enable elevator sorting"
1399 depends on SCSI_U14_34F
1401 This option enables elevator sorting for all probed SCSI disks and
1402 CD-ROMs. It definitely reduces the average seek distance when doing
1403 random seeks, but this does not necessarily result in a noticeable
1404 performance improvement: your mileage may vary...
1405 This is equivalent to the "u14-34f=lc:y" boot option.
1407 config SCSI_U14_34F_MAX_TAGS
1408 int "maximum number of queued commands"
1409 depends on SCSI_U14_34F
1412 This specifies how many SCSI commands can be maximally queued for
1413 each probed SCSI device. You should reduce the default value of 8
1414 only if you have disks with buggy or limited tagged command support.
1415 Minimum is 2 and maximum is 14. This value is also the window size
1416 used by the elevator sorting option above. The effective value used
1417 by the driver for each probed SCSI device is reported at boot time.

1452 This is a host adapter simulator that can simulate multiple hosts
1453 each with multiple dummy SCSI devices (disks). It defaults to one
1454 host adapter with one dummy SCSI disk. Each dummy disk uses kernel
1455 RAM as storage (i.e. it is a ramdisk). To save space when multiple
1456 dummy disks are simulated, they share the same kernel RAM for
1457 their storage. See <http://www.torque.net/sg/sdebug.html> for more

1479 drives a bus which is entirely internal to the machine (such as the
1480 7500, 7600, 8500, etc.), the MESH is capable of synchronous
1481 operation at up to 10 MB/s. On machines where the SCSI bus
1482 controlled by the MESH can have external devices connected, it is
1483 usually rated at 5 MB/s. 5 is a safe value here unless you know the
1484 MESH SCSI bus is internal only; in that case you can say 10. Say 0
1485 to disable synchronous operation.
