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
159 <file:Documentation/scsi/scsi-generic.txt> for more information.

167 tristate "SCSI media changer support"
170 This is a driver for SCSI media changers. Most common devices are

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/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),

189 it has an enclosure device. Selecting this option will just allow
190 certain enclosure conditions to be reported and is not required.
192 comment "Some SCSI devices (e.g. CD jukebox) support multiple LUNs"
195 config SCSI_MULTI_LUN
196 bool "Probe all LUNs on each SCSI device"
199 If you have a SCSI device that supports more than one LUN (Logical
200 Unit Number), e.g. a CD jukebox, and only one LUN is detected, you
201 can say Y here to force the SCSI driver to probe for multiple LUNs.
202 A SCSI device with multiple LUNs acts logically like multiple SCSI
203 devices. The vast majority of SCSI devices have only one LUN, and
204 so most people can say N here. The max_luns boot/module parameter
205 allows to override this setting.
207 config SCSI_CONSTANTS
208 bool "Verbose SCSI error reporting (kernel size +=12K)"
211 The error messages regarding your SCSI hardware will be easier to
212 understand if you say Y here; it will enlarge your kernel by about
213 12 KB. If in doubt, say Y.
216 bool "SCSI logging facility"
219 This turns on a logging facility that can be used to debug a number
220 of SCSI related problems.
222 If you say Y here, no logging output will appear by default, but you
223 can enable logging by saying Y to "/proc file system support" and
224 "Sysctl support" below and executing the command
226 echo "scsi log token [level]" > /proc/scsi/scsi
228 at boot time after the /proc file system has been mounted.
230 There are a number of things that can be used for 'token' (you can
231 find them in the source: <file:drivers/scsi/scsi.c>), and this
232 allows you to select the types of information you want, and the
233 level allows you to select the level of verbosity.
235 If you say N here, it may be harder to track down some types of SCSI
236 problems. If you say Y here your kernel will be somewhat larger, but
237 there should be no noticeable performance impact as long as you have
240 config SCSI_SCAN_ASYNC
241 bool "Asynchronous SCSI scanning"
244 The SCSI subsystem can probe for devices while the rest of the
245 system continues booting, and even probe devices on different
246 busses in parallel, leading to a significant speed-up.
248 If you have built SCSI as modules, enabling this option can
249 be a problem as the devices may not have been found by the
250 time your system expects them to have been. You can load the
251 scsi_wait_scan module to ensure that all scans have completed.
252 If you build your SCSI drivers into the kernel, then everything
253 will work fine if you say Y here.
255 You can override this choice by specifying "scsi_mod.scan=sync"
256 or async on the kernel's command line.

745 category, along with a large number of ISA 8bit controllers shipped
746 for free with SCSI scanners. If you have a PAS16, T128 or DMX3191
747 you should select the specific driver for that card rather than
748 generic 5380 support.
750 It is explained in section 3.8 of the SCSI-HOWTO, available from

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

785 tristate "IBMMCA SCSI support"
786 depends on MCA && SCSI
788 This is support for the IBM SCSI adapter found in many of the PS/2
789 series computers. These machines have an MCA bus, so you need to
790 answer Y to "MCA support" as well and read
791 <file:Documentation/mca.txt>.
793 If the adapter isn't found during boot (a common problem for models
794 56, 57, 76, and 77) you'll need to use the 'ibmmcascsi=<pun>' kernel
795 option, where <pun> is the id of the SCSI subsystem (usually 7, but
796 if that doesn't work check your reference diskette). Owners of
797 model 95 with a LED-matrix-display can in addition activate some
798 activity info like under OS/2, but more informative, by setting
799 'ibmmcascsi=display' as an additional kernel parameter. Try "man
800 bootparam" or see the documentation of your boot loader about how to
801 pass options to the kernel.

804 module will be called ibmmca.
806 config IBMMCA_SCSI_ORDER_STANDARD
807 bool "Standard SCSI-order"
808 depends on SCSI_IBMMCA
810 In the PC-world and in most modern SCSI-BIOS-setups, SCSI-hard disks
811 are assigned to the drive letters, starting with the lowest SCSI-id
812 (physical number -- pun) to be drive C:, as seen from DOS and
813 similar operating systems. When looking into papers describing the
814 ANSI-SCSI-standard, this assignment of drives appears to be wrong.
815 The SCSI-standard follows a hardware-hierarchy which says that id 7
816 has the highest priority and id 0 the lowest. Therefore, the host
817 adapters are still today everywhere placed as SCSI-id 7 by default.
818 In the SCSI-standard, the drive letters express the priority of the
819 disk. C: should be the hard disk, or a partition on it, with the
820 highest priority. This must therefore be the disk with the highest
821 SCSI-id (e.g. 6) and not the one with the lowest! IBM-BIOS kept the
822 original definition of the SCSI-standard as also industrial- and
823 process-control-machines, like VME-CPUs running under realtime-OSes
824 (e.g. LynxOS, OS9) do.
826 If you like to run Linux on your MCA-machine with the same
827 assignment of hard disks as seen from e.g. DOS or OS/2 on your
828 machine, which is in addition conformant to the SCSI-standard, you
829 must say Y here. This is also necessary for MCA-Linux users who want
830 to keep downward compatibility to older releases of the
831 IBM-MCA-SCSI-driver (older than driver-release 2.00 and older than
834 If you like to have the lowest SCSI-id assigned as drive C:, as
835 modern SCSI-BIOSes do, which does not conform to the standard, but

837 here. If unsure, say Y.
839 config IBMMCA_SCSI_DEV_RESET
840 bool "Reset SCSI-devices at boottime"

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

1005 Some parallel ports are known to have excessive delays between
1006 changing the parallel port control register and good data being
1007 available on the parallel port data/status register. This option
1008 forces a small delay (1.0 usec to be exact) after changing the

1109 capable (875A, 895A, 896, 1010-33, 1010-66, 1000).
1111 When set to 0, the driver will program the chip to only perform
1112 32-bit DMA. When set to 1, the chip will be able to perform DMA
1113 to addresses up to 1TB. When set to 2, the driver supports the
1114 full 64-bit DMA address range, but can only address 16 segments
1115 of 4 GB each. This limits the total addressable range to 64 GB.
1117 Most machines with less than 4GB of memory should use a setting
1118 of 0 for best performance. If your machine has 4GB of memory
1119 or more, you should set this option to 1 (the default).
1121 The still experimental value 2 (64 bit DMA addressing with 16

1207 int "default tagged command queue depth"
1208 depends on SCSI_ZALON || SCSI_NCR_Q720
1211 "Tagged command queuing" is a feature of SCSI-2 which improves
1212 performance: the host adapter can send several SCSI commands to a
1213 device's queue even if previous commands haven't finished yet.
1214 Because the device is intelligent, it can optimize its operations
1215 (like head positioning) based on its own request queue. Some SCSI
1216 devices don't implement this properly; if you want to disable this
1217 feature, enter 0 or 1 here (it doesn't matter which).
1219 The default value is 8 and should be supported by most hard disks.
1220 This value can be overridden from the boot command line using the
1221 'tags' option as follows (example):
1222 'ncr53c8xx=tags:4/t2t3q16/t0u2q10' will set default queue depth to
1223 4, set queue depth to 16 for target 2 and target 3 on controller 0
1224 and set queue depth to 10 for target 0 / lun 2 on controller 1.
1226 The normal answer therefore is to go with the default 8 and to use
1227 a boot command line option for devices that need to use a different
1228 command queue depth.
1230 There is no safe option other than using good SCSI devices.
1232 config SCSI_NCR53C8XX_MAX_TAGS
1233 int "maximum number of queued commands"
1234 depends on SCSI_ZALON || SCSI_NCR_Q720
1237 This option allows you to specify the maximum number of commands
1238 that can be queued to any device, when tagged command queuing is
1239 possible. The default value is 32. Minimum is 2, maximum is 64.
1240 Modern hard disks are able to support 64 tags and even more, but
1241 do not seem to be faster when more than 32 tags are being used.
1243 So, the normal answer here is to go with the default value 32 unless
1244 you are using very large hard disks with large cache (>= 1 MB) that
1245 are able to take advantage of more than 32 tagged commands.
1247 There is no safe option and the default answer is recommended.
1249 config SCSI_NCR53C8XX_SYNC
1250 int "synchronous transfers frequency in MHz"
1251 depends on SCSI_ZALON || SCSI_NCR_Q720
1254 The SCSI Parallel Interface-2 Standard defines 5 classes of transfer
1255 rates: FAST-5, FAST-10, FAST-20, FAST-40 and FAST-80. The numbers
1256 are respectively the maximum data transfer rates in mega-transfers
1257 per second for each class. For example, a FAST-20 Wide 16 device is
1258 able to transfer data at 20 million 16 bit packets per second for a
1259 total rate of 40 MB/s.
1261 You may specify 0 if you want to only use asynchronous data
1262 transfers. This is the safest and slowest option. Otherwise, specify
1263 a value between 5 and 80, depending on the capability of your SCSI
1264 controller. The higher the number, the faster the data transfer.
1265 Note that 80 should normally be ok since the driver decreases the
1266 value automatically according to the controller's capabilities.
1268 Your answer to this question is ignored for controllers with NVRAM,
1269 since the driver will get this information from the user set-up. It
1270 also can be overridden using a boot setup option, as follows
1271 (example): 'ncr53c8xx=sync:12' will allow the driver to negotiate
1272 for FAST-20 synchronous data transfer (20 mega-transfers per
1275 The normal answer therefore is not to go with the default but to
1276 select the maximum value 80 allowing the driver to use the maximum
1277 value supported by each controller. If this causes problems with
1278 your SCSI devices, you should come back and decrease the value.
1280 There is no safe option other than using good cabling, right
1281 terminations and SCSI conformant devices.

1284 bool "not allow targets to disconnect"
1285 depends on (SCSI_ZALON || SCSI_NCR_Q720) && SCSI_NCR53C8XX_DEFAULT_TAGS=0
1287 This option is only provided for safety if you suspect some SCSI
1288 device of yours to not support properly the target-disconnect
1289 feature. In that case, you would say Y here. In general however, to
1290 not allow targets to disconnect is not reasonable if there is more
1291 than 1 device on a SCSI bus. The normal answer therefore is N.

1382 the sym53c416 is configured first using some sort of PnP
1383 configuration program (e.g. isapnp) or by a PnP aware BIOS. If you
1384 are using isapnp then you need to compile this driver as a module

1459 config SCSI_U14_34F_TAGGED_QUEUE
1460 bool "enable tagged command queueing"
1461 depends on SCSI_U14_34F
1463 This is a feature of SCSI-2 which improves performance: the host
1464 adapter can send several SCSI commands to a device's queue even if
1465 previous commands haven't finished yet.
1466 This is equivalent to the "u14-34f=tc:y" boot option.
1468 config SCSI_U14_34F_LINKED_COMMANDS
1469 bool "enable elevator sorting"
1470 depends on SCSI_U14_34F
1472 This option enables elevator sorting for all probed SCSI disks and
1473 CD-ROMs. It definitely reduces the average seek distance when doing
1474 random seeks, but this does not necessarily result in a noticeable
1475 performance improvement: your mileage may vary...
1476 This is equivalent to the "u14-34f=lc:y" boot option.
1478 config SCSI_U14_34F_MAX_TAGS
1479 int "maximum number of queued commands"
1480 depends on SCSI_U14_34F
1483 This specifies how many SCSI commands can be maximally queued for
1484 each probed SCSI device. You should reduce the default value of 8
1485 only if you have disks with buggy or limited tagged command support.
1486 Minimum is 2 and maximum is 14. This value is also the window size
1487 used by the elevator sorting option above. The effective value used
1488 by the driver for each probed SCSI device is reported at boot time.

1520 tristate "SCSI debugging host simulator"
1523 This is a host adapter simulator that can simulate multiple hosts
1524 each with multiple dummy SCSI devices (disks). It defaults to one
1525 host adapter with one dummy SCSI disk. Each dummy disk uses kernel
1526 RAM as storage (i.e. it is a ramdisk). To save space when multiple
1527 dummy disks are simulated, they share the same kernel RAM for
1528 their storage. See <http://www.torque.net/sg/sdebug.html> for more
1529 information. This driver is primarily of use to those testing the
1530 SCSI and block subsystems. If unsure, say N.

1549 On Power Macintoshes (and clones) where the MESH SCSI bus adaptor
1550 drives a bus which is entirely internal to the machine (such as the
1551 7500, 7600, 8500, etc.), the MESH is capable of synchronous
1552 operation at up to 10 MB/s. On machines where the SCSI bus
1553 controlled by the MESH can have external devices connected, it is
1554 usually rated at 5 MB/s. 5 is a safe value here unless you know the
1555 MESH SCSI bus is internal only; in that case you can say 10. Say 0
1556 to disable synchronous operation.

1567 On Power Macintoshes (and clones) with two SCSI buses, the external
1568 SCSI bus is usually controlled by a 53C94 SCSI bus adaptor. Older
1569 machines which only have one SCSI bus, such as the 7200, also use
