15 If you want to use a SCSI hard disk, SCSI tape drive, SCSI CD-ROM or
16 any other SCSI device under Linux, say Y and make sure that you know
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.
20
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.

26 To compile this driver as a module, choose M here and read

28 The module will be called scsi_mod.

30 However, do not compile this as a module if your root file system

231 There are a number of things that can be used for 'token' (you can

469 WARNING This driver is an older aic7xxx driver and is no longer

471 take the place of this one, and it is recommended that whenever
472 possible, people should use the new Adaptec written driver instead
473 of this one. This driver will eventually be phased out entirely.
474
475 This is support for the various aic7xxx based Adaptec SCSI
476 controllers. These include the 274x EISA cards; 284x VLB cards;
477 2902, 2910, 293x, 294x, 394x, 3985 and several other PCI and
478 motherboard based SCSI controllers from Adaptec. It does not support
479 the AAA-13x RAID controllers from Adaptec, nor will it likely ever
480 support them. It does not support the 2920 cards from Adaptec that
481 use the Future Domain SCSI controller chip. For those cards, you
482 need the "Future Domain 16xx SCSI support" driver.
483
484 In general, if the controller is based on an Adaptec SCSI controller
485 chip from the aic777x series or the aic78xx series, this driver
486 should work. The only exception is the 7810 which is specifically
487 not supported (that's the RAID controller chip on the AAA-13x
488 cards).
489
490 Note that the AHA2920 SCSI host adapter is *not* supported by this
491 driver; choose "Future Domain 16xx SCSI support" instead if you have
492 one of those.
493
494 Information on the configuration options for this controller can be
495 found by checking the help file for each of the available
496 configuration options. You should read

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

807config IBMMCA_SCSI_ORDER_STANDARD
808 bool "Standard SCSI-order"
809 depends on SCSI_IBMMCA
810 ---help---
811 In the PC-world and in most modern SCSI-BIOS-setups, SCSI-hard disks
812 are assigned to the drive letters, starting with the lowest SCSI-id
813 (physical number -- pun) to be drive C:, as seen from DOS and
814 similar operating systems. When looking into papers describing the
815 ANSI-SCSI-standard, this assignment of drives appears to be wrong.
816 The SCSI-standard follows a hardware-hierarchy which says that id 7
817 has the highest priority and id 0 the lowest. Therefore, the host
818 adapters are still today everywhere placed as SCSI-id 7 by default.
819 In the SCSI-standard, the drive letters express the priority of the
820 disk. C: should be the hard disk, or a partition on it, with the
821 highest priority. This must therefore be the disk with the highest
822 SCSI-id (e.g. 6) and not the one with the lowest! IBM-BIOS kept the
823 original definition of the SCSI-standard as also industrial- and
824 process-control-machines, like VME-CPUs running under realtime-OSes
825 (e.g. LynxOS, OS9) do.
826
827 If you like to run Linux on your MCA-machine with the same
828 assignment of hard disks as seen from e.g. DOS or OS/2 on your
829 machine, which is in addition conformant to the SCSI-standard, you
830 must say Y here. This is also necessary for MCA-Linux users who want
831 to keep downward compatibility to older releases of the
832 IBM-MCA-SCSI-driver (older than driver-release 2.00 and older than
833 June 1997).
834
835 If you like to have the lowest SCSI-id assigned as drive C:, as
836 modern SCSI-BIOSes do, which does not conform to the standard, but
837 is widespread and common in the PC-world of today, you must say N
838 here. If unsure, say Y.

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

1211 ---help---
1212 "Tagged command queuing" is a feature of SCSI-2 which improves
1213 performance: the host adapter can send several SCSI commands to a
1214 device's queue even if previous commands haven't finished yet.
1215 Because the device is intelligent, it can optimize its operations
1216 (like head positioning) based on its own request queue. Some SCSI
1217 devices don't implement this properly; if you want to disable this
1218 feature, enter 0 or 1 here (it doesn't matter which).
1219
1220 The default value is 8 and should be supported by most hard disks.
1221 This value can be overridden from the boot command line using the
1222 'tags' option as follows (example):
1223 'ncr53c8xx=tags:4/t2t3q16/t0u2q10' will set default queue depth to
1224 4, set queue depth to 16 for target 2 and target 3 on controller 0
1225 and set queue depth to 10 for target 0 / lun 2 on controller 1.
1226
1227 The normal answer therefore is to go with the default 8 and to use
1228 a boot command line option for devices that need to use a different
1229 command queue depth.
1230
1231 There is no safe option other than using good SCSI devices.

1237 ---help---
1238 This option allows you to specify the maximum number of commands
1239 that can be queued to any device, when tagged command queuing is
1240 possible. The default value is 32. Minimum is 2, maximum is 64.
1241 Modern hard disks are able to support 64 tags and even more, but
1242 do not seem to be faster when more than 32 tags are being used.
1243
1244 So, the normal answer here is to go with the default value 32 unless
1245 you are using very large hard disks with large cache (>= 1 MB) that
1246 are able to take advantage of more than 32 tagged commands.
1247
1248 There is no safe option and the default answer is recommended.

1254 ---help---
1255 The SCSI Parallel Interface-2 Standard defines 5 classes of transfer
1256 rates: FAST-5, FAST-10, FAST-20, FAST-40 and FAST-80. The numbers
1257 are respectively the maximum data transfer rates in mega-transfers
1258 per second for each class. For example, a FAST-20 Wide 16 device is
1259 able to transfer data at 20 million 16 bit packets per second for a
1260 total rate of 40 MB/s.
1261
1262 You may specify 0 if you want to only use asynchronous data
1263 transfers. This is the safest and slowest option. Otherwise, specify
1264 a value between 5 and 80, depending on the capability of your SCSI
1265 controller. The higher the number, the faster the data transfer.
1266 Note that 80 should normally be ok since the driver decreases the
1267 value automatically according to the controller's capabilities.
1268
1269 Your answer to this question is ignored for controllers with NVRAM,
1270 since the driver will get this information from the user set-up. It
1271 also can be overridden using a boot setup option, as follows
1272 (example): 'ncr53c8xx=sync:12' will allow the driver to negotiate
1273 for FAST-20 synchronous data transfer (20 mega-transfers per
1274 second).
1275
1276 The normal answer therefore is not to go with the default but to
1277 select the maximum value 80 allowing the driver to use the maximum
1278 value supported by each controller. If this causes problems with
1279 your SCSI devices, you should come back and decrease the value.
1280
1281 There is no safe option other than using good cabling, right
1282 terminations and SCSI conformant devices.
