4 tristate "SCSI device support"
6 If you want to use a SCSI hard disk, SCSI tape drive, SCSI CD-ROM or
7 any other SCSI device under Linux, say Y and make sure that you know
8 the name of your SCSI host adapter (the card inside your computer
9 that "speaks" the SCSI protocol, also called SCSI controller),
10 because you will be asked for it.
12 You also need to say Y here if you have a device which speaks
13 the SCSI protocol. Examples of this include the parallel port
14 version of the IOMEGA ZIP drive, USB storage devices, Fibre
15 Channel, FireWire storage and the IDE-SCSI emulation driver.
17 To compile this driver as a module, choose M here and read
18 <file:Documentation/scsi/scsi.txt>.
19 The module will be called scsi_mod.
21 However, do not compile this as a module if your root file system
22 (the one containing the directory /) is located on a SCSI device.
25 bool "legacy /proc/scsi/ support"
26 depends on SCSI && PROC_FS
29 This option enables support for the various files in
30 /proc/scsi. In Linux 2.6 this has been superceeded by
31 files in sysfs but many legacy applications rely on this.

42 If you want to use SCSI hard disks, Fibre Channel disks,
43 USB storage or the SCSI or parallel port version of
44 the IOMEGA ZIP drive, say Y and read the SCSI-HOWTO,
45 the Disk-HOWTO and the Multi-Disk-HOWTO, available from
46 <http://www.tldp.org/docs.html#howto>. This is NOT for SCSI

53 Do not compile this driver as a module if your root file system
54 (the one containing the directory /) is located on a SCSI disk.
55 In this case, do not compile the driver for your SCSI host adapter
56 (below) as a module either.
59 tristate "SCSI tape support"
62 If you want to use a SCSI tape drive under Linux, say Y and read the

72 tristate "SCSI OnStream SC-x0 tape support"
75 The OnStream SC-x0 SCSI tape drives can not be driven by the
76 standard st driver, but instead need this special osst driver and
77 use the /dev/osstX char device nodes (major 206). Via usb-storage
78 and ide-scsi, you may be able to drive the USB-x0 and DI-x0 drives
79 as well. Note that there is also a second generation of OnStream
80 tape drives (ADR-x0) that supports the standard SCSI-2 commands for
81 tapes (QIC-157) and can be driven by the standard driver st.
82 For more information, you may have a look at the SCSI-HOWTO
83 <http://www.tldp.org/docs.html#howto> and
84 <file:Documentation/scsi/osst.txt> in the kernel source.
85 More info on the OnStream driver may be found on
86 <http://linux1.onstream.nl/test/>
87 Please also have a look at the standard st docu, as most of it
88 applies to osst as well.
90 To compile this driver as a module, choose M here and read
91 <file:Documentation/scsi/scsi.txt>. The module will be called osst.
94 tristate "SCSI CDROM support"
97 If you want to use a SCSI or FireWire CD-ROM under Linux,
98 say Y and read the SCSI-HOWTO and the CDROM-HOWTO at
99 <http://www.tldp.org/docs.html#howto>. Also make sure to say
100 Y or M to "ISO 9660 CD-ROM file system support" later.
102 To compile this driver as a module, choose M here and read

104 The module will be called sr_mod.
106 config BLK_DEV_SR_VENDOR
107 bool "Enable vendor-specific extensions (for SCSI CDROM)"
108 depends on BLK_DEV_SR
110 This enables the usage of vendor specific SCSI commands. This is
111 required to support multisession CDs with old NEC/TOSHIBA cdrom
112 drives (and HP Writers). If you have such a drive and get the first
113 session only, try saying Y here; everybody else says N.
116 tristate "SCSI generic support"
119 If you want to use SCSI scanners, synthesizers or CD-writers or just
120 about anything having "SCSI" in its name other than hard disks,
121 CD-ROMs or tapes, say Y here. These won't be supported by the kernel
122 directly, so you need some additional software which knows how to
123 talk to these devices using the SCSI protocol:
125 For scanners, look at SANE (<http://www.mostang.com/sane/>). For CD
126 writer software look at Cdrtools
127 (<http://www.fokus.gmd.de/research/cc/glone/employees/joerg.schilling/private/cdrecord.html>)
128 and for burning a "disk at once": CDRDAO
129 (<http://cdrdao.sourceforge.net/>). Cdparanoia is a high
130 quality digital reader of audio CDs (<http://www.xiph.org/paranoia/>).
131 For other devices, it's possible that you'll have to write the
132 driver software yourself. Please read the file
133 <file:Documentation/scsi/scsi-generic.txt> for more information.
135 To compile this driver as a module, choose M here and read
136 <file:Documentation/scsi/scsi.txt>. The module will be called sg.
141 tristate "SCSI media changer support"
144 This is a driver for SCSI media changers. Most common devices are
145 tape libraries and MOD/CDROM jukeboxes. *Real* jukeboxes, you
146 don't need this for those tiny 6-slot cdrom changers. Media
147 changers are listed as "Type: Medium Changer" in /proc/scsi/scsi.
148 If you have such hardware and want to use it with linux, say Y
149 here. Check <file:Documentation/scsi-changer.txt> for details.
151 If you want to compile this as a module ( = code which can be
152 inserted in and removed from the running kernel whenever you want),
153 say M here and read <file:Documentation/modules.txt> and
154 <file:Documentation/scsi.txt>. The module will be called ch.o.
158 comment "Some SCSI devices (e.g. CD jukebox) support multiple LUNs"
161 config SCSI_MULTI_LUN
162 bool "Probe all LUNs on each SCSI device"
165 If you have a SCSI device that supports more than one LUN (Logical
166 Unit Number), e.g. a CD jukebox, and only one LUN is detected, you
167 can say Y here to force the SCSI driver to probe for multiple LUNs.
168 A SCSI device with multiple LUNs acts logically like multiple SCSI
169 devices. The vast majority of SCSI devices have only one LUN, and
170 so most people can say N here. The max_luns boot/module parameter
171 allows to override this setting.
173 config SCSI_CONSTANTS
174 bool "Verbose SCSI error reporting (kernel size +=12K)"
177 The error messages regarding your SCSI hardware will be easier to
178 understand if you say Y here; it will enlarge your kernel by about
179 12 KB. If in doubt, say Y.
182 bool "SCSI logging facility"
185 This turns on a logging facility that can be used to debug a number
186 of SCSI related problems.
188 If you say Y here, no logging output will appear by default, but you
189 can enable logging by saying Y to "/proc file system support" and
190 "Sysctl support" below and executing the command
192 echo "scsi log token [level]" > /proc/scsi/scsi
194 at boot time after the /proc file system has been mounted.
196 There are a number of things that can be used for 'token' (you can
197 find them in the source: <file:drivers/scsi/scsi.c>), and this
198 allows you to select the types of information you want, and the
199 level allows you to select the level of verbosity.
201 If you say N here, it may be harder to track down some types of SCSI
202 problems. If you say Y here your kernel will be somewhat larger, but
203 there should be no noticeable performance impact as long as you have

703 on boards using PIO. Most boards such as the Trantor T130 fit this
704 category, along with a large number of ISA 8bit controllers shipped
705 for free with SCSI scanners. If you have a PAS16, T128 or DMX3191
706 you should select the specific driver for that card rather than
707 generic 5380 support.
709 It is explained in section 3.8 of the SCSI-HOWTO, available from
710 <http://www.tldp.org/docs.html#howto>. If it doesn't work out
711 of the box, you may have to change some settings in

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

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

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

798 bool "Reset SCSI-devices at boottime"

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

929 Some parallel ports are known to have excessive delays between
930 changing the parallel port control register and good data being
931 available on the parallel port data/status register. This option
932 forces a small delay (1.0 usec to be exact) after changing the
933 control register to let things settle out. Enabling this option may
934 result in a big drop in performance but some very old parallel ports
935 (found in 386 vintage machines) will not work properly.

984 Ultra-160 controllers that are based on the SYM53C8XX SCRIPTS
985 language. It does not support LSI53C10XX Ultra-320 PCI-X SCSI

991 config SCSI_SYM53C8XX_DMA_ADDRESSING_MODE
992 int "DMA addressing mode"
993 depends on SCSI_SYM53C8XX_2
996 This option only applies to PCI-SCSI chips that are PCI DAC
997 capable (875A, 895A, 896, 1010-33, 1010-66, 1000).
999 When set to 0, the driver will program the chip to only perform
1000 32-bit DMA. When set to 1, the chip will be able to perform DMA
1001 to addresses up to 1TB. When set to 2, the driver supports the
1002 full 64-bit DMA address range, but can only address 16 segments
1003 of 4 GB each. This limits the total addressable range to 64 GB.
1005 Most machines with less than 4GB of memory should use a setting
1006 of 0 for best performance. If your machine has 4GB of memory
1007 or more, you should set this option to 1 (the default).
1009 The still experimental value 2 (64 bit DMA addressing with 16
1010 x 4GB segments limitation) can be used on systems that require
1011 PCI address bits past bit 39 to be set for the addressing of
1012 memory using PCI DAC cycles.

1019 This is the default value of the command queue depth the
1020 driver will announce to the generic SCSI layer for devices
1021 that support tagged command queueing. This value can be changed
1022 from the boot command line. This is a soft limit that cannot
1023 exceed CONFIG_SCSI_SYM53C8XX_MAX_TAGS.
1025 config SCSI_SYM53C8XX_MAX_TAGS
1026 int "maximum number of queued commands"
1027 depends on SCSI_SYM53C8XX_2
1030 This option allows you to specify the maximum number of commands
1031 that can be queued to any device, when tagged command queuing is
1032 possible. The driver supports up to 256 queued commands per device.
1033 This value is used as a compiled-in hard limit.
1035 config SCSI_SYM53C8XX_IOMAPPED
1037 depends on SCSI_SYM53C8XX_2
1039 If you say Y here, the driver will use port IO to access
1040 the card. This is significantly slower then using memory
1041 mapped IO. Most people should answer N.

1084 This is a driver for the MicroChannel Quad 720 card produced by
1085 NCR and commonly used in 345x/35xx/4100 class machines. It always
1086 tries to negotiate sync and uses tag command queueing.
1088 Unless you have an NCR manufactured machine, the chances are that
1089 you do not have this SCSI card, so say N.
1091 config SCSI_NCR53C8XX_DEFAULT_TAGS
1092 int " default tagged command queue depth"
1093 depends on SCSI_ZALON || SCSI_NCR_Q720
1096 "Tagged command queuing" is a feature of SCSI-2 which improves
1097 performance: the host adapter can send several SCSI commands to a
1098 device's queue even if previous commands haven't finished yet.
1099 Because the device is intelligent, it can optimize its operations
1100 (like head positioning) based on its own request queue. Some SCSI
1101 devices don't implement this properly; if you want to disable this
1102 feature, enter 0 or 1 here (it doesn't matter which).
1104 The default value is 8 and should be supported by most hard disks.
1105 This value can be overridden from the boot command line using the
1106 'tags' option as follows (example):
1107 'ncr53c8xx=tags:4/t2t3q16/t0u2q10' will set default queue depth to
1108 4, set queue depth to 16 for target 2 and target 3 on controller 0
1109 and set queue depth to 10 for target 0 / lun 2 on controller 1.
1111 The normal answer therefore is to go with the default 8 and to use
1112 a boot command line option for devices that need to use a different
1113 command queue depth.
1115 There is no safe option other than using good SCSI devices.
1117 config SCSI_NCR53C8XX_MAX_TAGS
1118 int " maximum number of queued commands"
1119 depends on SCSI_ZALON || SCSI_NCR_Q720
1122 This option allows you to specify the maximum number of commands
1123 that can be queued to any device, when tagged command queuing is
1124 possible. The default value is 32. Minimum is 2, maximum is 64.
1125 Modern hard disks are able to support 64 tags and even more, but
1126 do not seem to be faster when more than 32 tags are being used.
1128 So, the normal answer here is to go with the default value 32 unless
1129 you are using very large hard disks with large cache (>= 1 MB) that
1130 are able to take advantage of more than 32 tagged commands.
1132 There is no safe option and the default answer is recommended.
1134 config SCSI_NCR53C8XX_SYNC
1135 int " synchronous transfers frequency in MHz"
1136 depends on SCSI_ZALON || SCSI_NCR_Q720
1139 The SCSI Parallel Interface-2 Standard defines 5 classes of transfer
1140 rates: FAST-5, FAST-10, FAST-20, FAST-40 and FAST-80. The numbers
1141 are respectively the maximum data transfer rates in mega-transfers
1142 per second for each class. For example, a FAST-20 Wide 16 device is
1143 able to transfer data at 20 million 16 bit packets per second for a
1144 total rate of 40 MB/s.
1146 You may specify 0 if you want to only use asynchronous data
1147 transfers. This is the safest and slowest option. Otherwise, specify
1148 a value between 5 and 80, depending on the capability of your SCSI
1149 controller. The higher the number, the faster the data transfer.
1150 Note that 80 should normally be ok since the driver decreases the
1151 value automatically according to the controller's capabilities.
1153 Your answer to this question is ignored for controllers with NVRAM,
1154 since the driver will get this information from the user set-up. It
1155 also can be overridden using a boot setup option, as follows
1156 (example): 'ncr53c8xx=sync:12' will allow the driver to negotiate
1157 for FAST-20 synchronous data transfer (20 mega-transfers per
1160 The normal answer therefore is not to go with the default but to
1161 select the maximum value 80 allowing the driver to use the maximum
1162 value supported by each controller. If this causes problems with
1163 your SCSI devices, you should come back and decrease the value.
1165 There is no safe option other than using good cabling, right
1166 terminations and SCSI conformant devices.
1168 config SCSI_NCR53C8XX_PROFILE
1169 bool " enable profiling"
1170 depends on SCSI_ZALON || SCSI_NCR_Q720
1172 This option allows you to enable profiling information gathering.
1173 These statistics are not very accurate due to the low frequency
1174 of the kernel clock (100 Hz on i386) and have performance impact
1175 on systems that use very fast devices.
1177 The normal answer therefore is N.
1179 config SCSI_NCR53C8XX_NO_DISCONNECT
1180 bool " not allow targets to disconnect"
1181 depends on (SCSI_ZALON || SCSI_NCR_Q720) && SCSI_NCR53C8XX_DEFAULT_TAGS=0
1183 This option is only provided for safety if you suspect some SCSI
1184 device of yours to not support properly the target-disconnect
1185 feature. In that case, you would say Y here. In general however, to
1186 not allow targets to disconnect is not reasonable if there is more
1187 than 1 device on a SCSI bus. The normal answer therefore is N.

1355 the sym53c416 is configured first using some sort of PnP
1356 configuration program (e.g. isapnp) or by a PnP aware BIOS. If you
1357 are using isapnp then you need to compile this driver as a module

1430 config SCSI_U14_34F_TAGGED_QUEUE
1431 bool "enable tagged command queueing"
1432 depends on SCSI_U14_34F
1434 This is a feature of SCSI-2 which improves performance: the host
1435 adapter can send several SCSI commands to a device's queue even if
1436 previous commands haven't finished yet.
1437 This is equivalent to the "u14-34f=tc:y" boot option.
1439 config SCSI_U14_34F_LINKED_COMMANDS
1440 bool "enable elevator sorting"
1441 depends on SCSI_U14_34F
1443 This option enables elevator sorting for all probed SCSI disks and
1444 CD-ROMs. It definitely reduces the average seek distance when doing
1445 random seeks, but this does not necessarily result in a noticeable
1446 performance improvement: your mileage may vary...
1447 This is equivalent to the "u14-34f=lc:y" boot option.
1449 config SCSI_U14_34F_MAX_TAGS
1450 int "maximum number of queued commands"
1451 depends on SCSI_U14_34F
1454 This specifies how many SCSI commands can be maximally queued for
1455 each probed SCSI device. You should reduce the default value of 8
1456 only if you have disks with buggy or limited tagged command support.
1457 Minimum is 2 and maximum is 14. This value is also the window size
1458 used by the elevator sorting option above. The effective value used
1459 by the driver for each probed SCSI device is reported at boot time.

1491 tristate "SCSI debugging host simulator"
1494 This is a host adapter simulator that can simulate multiple hosts
1495 each with multiple dummy SCSI devices (disks). It defaults to one
1496 host adapter with one dummy SCSI disk. Each dummy disk uses kernel
1497 RAM as storage (i.e. it is a ramdisk). To save space when multiple
1498 dummy disks are simulated, they share the same kernel RAM for
1499 their storage. See <http://www.torque.net/sg/sdebug.html> for more
1500 information. This driver is primarily of use to those testing the
1501 SCSI and block subsystems. If unsure, say N.

1520 On Power Macintoshes (and clones) where the MESH SCSI bus adaptor
1521 drives a bus which is entirely internal to the machine (such as the
1522 7500, 7600, 8500, etc.), the MESH is capable of synchronous
1523 operation at up to 10 MB/s. On machines where the SCSI bus
1524 controlled by the MESH can have external devices connected, it is
1525 usually rated at 5 MB/s. 5 is a safe value here unless you know the
1526 MESH SCSI bus is internal only; in that case you can say 10. Say 0
1527 to disable synchronous operation.
