17 the name of your SCSI host adapter (the card inside your computer
18 that "speaks" the SCSI protocol, also called SCSI controller),
19 because you will be asked for it.
21 You also need to say Y here if you have a device which speaks
22 the SCSI protocol. Examples of this include the parallel port
23 version of the IOMEGA ZIP drive, USB storage devices, Fibre
24 Channel, FireWire storage and the IDE-SCSI emulation driver.

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

138 drives (and HP Writers). If you have such a drive and get the first
139 session only, try saying Y here; everybody else says N.
142 tristate "SCSI generic support"
145 If you want to use SCSI scanners, synthesizers or CD-writers or just
146 about anything having "SCSI" in its name other than hard disks,
147 CD-ROMs or tapes, say Y here. These won't be supported by the kernel
148 directly, so you need some additional software which knows how to
149 talk to these devices using the SCSI protocol:
151 For scanners, look at SANE (<http://www.mostang.com/sane/>). For CD
152 writer software look at Cdrtools
153 (<http://www.fokus.gmd.de/research/cc/glone/employees/joerg.schilling/private/cdrecord.html>)
154 and for burning a "disk at once": CDRDAO
155 (<http://cdrdao.sourceforge.net/>). Cdparanoia is a high
156 quality digital reader of audio CDs (<http://www.xiph.org/paranoia/>).
157 For other devices, it's possible that you'll have to write the
158 driver software yourself. Please read the file

170 This is a driver for SCSI media changers. Most common devices are
171 tape libraries and MOD/CDROM jukeboxes. *Real* jukeboxes, you
172 don't need this for those tiny 6-slot cdrom changers. Media
173 changers are listed as "Type: Medium Changer" in /proc/scsi/scsi.
174 If you have such hardware and want to use it with linux, say Y
175 here. Check <file:Documentation/scsi-changer.txt> for details.
177 If you want to compile this as a module ( = code which can be
178 inserted in and removed from the running kernel whenever you want),

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

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

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

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

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

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

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

1040 capable (875A, 895A, 896, 1010-33, 1010-66, 1000).
1042 When set to 0, the driver will program the chip to only perform
1043 32-bit DMA. When set to 1, the chip will be able to perform DMA
1044 to addresses up to 1TB. When set to 2, the driver supports the
1045 full 64-bit DMA address range, but can only address 16 segments
1046 of 4 GB each. This limits the total addressable range to 64 GB.
1048 Most machines with less than 4GB of memory should use a setting
1049 of 0 for best performance. If your machine has 4GB of memory
1050 or more, you should set this option to 1 (the default).
1052 The still experimental value 2 (64 bit DMA addressing with 16
1053 x 4GB segments limitation) can be used on systems that require
1054 PCI address bits past bit 39 to be set for the addressing of

1131 NCR and commonly used in 345x/35xx/4100 class machines. It always

1138 int "default tagged command queue depth"
1139 depends on SCSI_ZALON || SCSI_NCR_Q720
1142 "Tagged command queuing" is a feature of SCSI-2 which improves
1143 performance: the host adapter can send several SCSI commands to a
1144 device's queue even if previous commands haven't finished yet.
1145 Because the device is intelligent, it can optimize its operations
1146 (like head positioning) based on its own request queue. Some SCSI
1147 devices don't implement this properly; if you want to disable this
1148 feature, enter 0 or 1 here (it doesn't matter which).
1150 The default value is 8 and should be supported by most hard disks.
1151 This value can be overridden from the boot command line using the
1152 'tags' option as follows (example):
1153 'ncr53c8xx=tags:4/t2t3q16/t0u2q10' will set default queue depth to
1154 4, set queue depth to 16 for target 2 and target 3 on controller 0
1155 and set queue depth to 10 for target 0 / lun 2 on controller 1.
1157 The normal answer therefore is to go with the default 8 and to use
1158 a boot command line option for devices that need to use a different
1159 command queue depth.
1161 There is no safe option other than using good SCSI devices.
1163 config SCSI_NCR53C8XX_MAX_TAGS
1164 int "maximum number of queued commands"
1165 depends on SCSI_ZALON || SCSI_NCR_Q720
1168 This option allows you to specify the maximum number of commands
1169 that can be queued to any device, when tagged command queuing is
1170 possible. The default value is 32. Minimum is 2, maximum is 64.
1171 Modern hard disks are able to support 64 tags and even more, but
1172 do not seem to be faster when more than 32 tags are being used.
1174 So, the normal answer here is to go with the default value 32 unless
1175 you are using very large hard disks with large cache (>= 1 MB) that
1176 are able to take advantage of more than 32 tagged commands.
1178 There is no safe option and the default answer is recommended.
1180 config SCSI_NCR53C8XX_SYNC
1181 int "synchronous transfers frequency in MHz"
1182 depends on SCSI_ZALON || SCSI_NCR_Q720
1185 The SCSI Parallel Interface-2 Standard defines 5 classes of transfer
1186 rates: FAST-5, FAST-10, FAST-20, FAST-40 and FAST-80. The numbers
1187 are respectively the maximum data transfer rates in mega-transfers
1188 per second for each class. For example, a FAST-20 Wide 16 device is
1189 able to transfer data at 20 million 16 bit packets per second for a
1190 total rate of 40 MB/s.
1192 You may specify 0 if you want to only use asynchronous data
1193 transfers. This is the safest and slowest option. Otherwise, specify
1194 a value between 5 and 80, depending on the capability of your SCSI
1195 controller. The higher the number, the faster the data transfer.
1196 Note that 80 should normally be ok since the driver decreases the
1197 value automatically according to the controller's capabilities.
1199 Your answer to this question is ignored for controllers with NVRAM,
1200 since the driver will get this information from the user set-up. It
1201 also can be overridden using a boot setup option, as follows
1202 (example): 'ncr53c8xx=sync:12' will allow the driver to negotiate
1203 for FAST-20 synchronous data transfer (20 mega-transfers per
1206 The normal answer therefore is not to go with the default but to
1207 select the maximum value 80 allowing the driver to use the maximum
1208 value supported by each controller. If this causes problems with
1209 your SCSI devices, you should come back and decrease the value.
1211 There is no safe option other than using good cabling, right
1212 terminations and SCSI conformant devices.

1218 This option is only provided for safety if you suspect some SCSI
1219 device of yours to not support properly the target-disconnect
1220 feature. In that case, you would say Y here. In general however, to
1221 not allow targets to disconnect is not reasonable if there is more

1349 the sym53c416 is configured first using some sort of PnP
1350 configuration program (e.g. isapnp) or by a PnP aware BIOS. If you
1351 are using isapnp then you need to compile this driver as a module

1425 config SCSI_U14_34F_TAGGED_QUEUE
1426 bool "enable tagged command queueing"
1427 depends on SCSI_U14_34F
1429 This is a feature of SCSI-2 which improves performance: the host
1430 adapter can send several SCSI commands to a device's queue even if
1431 previous commands haven't finished yet.
1432 This is equivalent to the "u14-34f=tc:y" boot option.
1434 config SCSI_U14_34F_LINKED_COMMANDS
1435 bool "enable elevator sorting"
1436 depends on SCSI_U14_34F
1438 This option enables elevator sorting for all probed SCSI disks and
1439 CD-ROMs. It definitely reduces the average seek distance when doing
1440 random seeks, but this does not necessarily result in a noticeable
1441 performance improvement: your mileage may vary...
1442 This is equivalent to the "u14-34f=lc:y" boot option.
1444 config SCSI_U14_34F_MAX_TAGS
1445 int "maximum number of queued commands"
1446 depends on SCSI_U14_34F
1449 This specifies how many SCSI commands can be maximally queued for
1450 each probed SCSI device. You should reduce the default value of 8
1451 only if you have disks with buggy or limited tagged command support.
1452 Minimum is 2 and maximum is 14. This value is also the window size
1453 used by the elevator sorting option above. The effective value used
1454 by the driver for each probed SCSI device is reported at boot time.
1455 This is equivalent to the "u14-34f=mq:8" boot option.

1486 tristate "SCSI debugging host simulator"
1489 This is a host adapter simulator that can simulate multiple hosts
1490 each with multiple dummy SCSI devices (disks). It defaults to one
1491 host adapter with one dummy SCSI disk. Each dummy disk uses kernel
1492 RAM as storage (i.e. it is a ramdisk). To save space when multiple
1493 dummy disks are simulated, they share the same kernel RAM for
1494 their storage. See <http://www.torque.net/sg/sdebug.html> for more
1495 information. This driver is primarily of use to those testing the
1496 SCSI and block subsystems. If unsure, say N.

1515 On Power Macintoshes (and clones) where the MESH SCSI bus adaptor
1516 drives a bus which is entirely internal to the machine (such as the
1517 7500, 7600, 8500, etc.), the MESH is capable of synchronous
1518 operation at up to 10 MB/s. On machines where the SCSI bus
1519 controlled by the MESH can have external devices connected, it is
1520 usually rated at 5 MB/s. 5 is a safe value here unless you know the
1521 MESH SCSI bus is internal only; in that case you can say 10. Say 0
1522 to disable synchronous operation.
