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.

22 the SCSI protocol. Examples of this include the parallel port

342 SCSI requests and responses over a TCP/IP network between the host

344 combines with the host's TCP/IP stack, network drivers, and Network

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

474 take the place of this one, and it is recommended that whenever
475 possible, people should use the new Adaptec written driver instead
476 of this one. This driver will eventually be phased out entirely.
477
478 This is support for the various aic7xxx based Adaptec SCSI
479 controllers. These include the 274x EISA cards; 284x VLB cards;
480 2902, 2910, 293x, 294x, 394x, 3985 and several other PCI and
481 motherboard based SCSI controllers from Adaptec. It does not support
482 the AAA-13x RAID controllers from Adaptec, nor will it likely ever
483 support them. It does not support the 2920 cards from Adaptec that
484 use the Future Domain SCSI controller chip. For those cards, you
485 need the "Future Domain 16xx SCSI support" driver.
486
487 In general, if the controller is based on an Adaptec SCSI controller
488 chip from the aic777x series or the aic78xx series, this driver
489 should work. The only exception is the 7810 which is specifically
490 not supported (that's the RAID controller chip on the AAA-13x
491 cards).
492
493 Note that the AHA2920 SCSI host adapter is *not* supported by this
494 driver; choose "Future Domain 16xx SCSI support" instead if you have
495 one of those.
496
497 Information on the configuration options for this controller can be
498 found by checking the help file for each of the available
499 configuration options. You should read
500 <file:Documentation/scsi/aic7xxx_old.txt> at a minimum before

762 This is a driver for the old NCR 53c80 series of SCSI controllers
763 on boards using PIO. Most boards such as the Trantor T130 fit this
764 category, along with a large number of ISA 8bit controllers shipped

811
812 If the adapter isn't found during boot (a common problem for models
813 56, 57, 76, and 77) you'll need to use the 'ibmmcascsi=<pun>' kernel
814 option, where <pun> is the id of the SCSI subsystem (usually 7, but
815 if that doesn't work check your reference diskette). Owners of
816 model 95 with a LED-matrix-display can in addition activate some
817 activity info like under OS/2, but more informative, by setting
818 'ibmmcascsi=display' as an additional kernel parameter. Try "man

827 depends on SCSI_IBMMCA
828 ---help---
829 In the PC-world and in most modern SCSI-BIOS-setups, SCSI-hard disks
830 are assigned to the drive letters, starting with the lowest SCSI-id
831 (physical number -- pun) to be drive C:, as seen from DOS and
832 similar operating systems. When looking into papers describing the
833 ANSI-SCSI-standard, this assignment of drives appears to be wrong.
834 The SCSI-standard follows a hardware-hierarchy which says that id 7
835 has the highest priority and id 0 the lowest. Therefore, the host
836 adapters are still today everywhere placed as SCSI-id 7 by default.
837 In the SCSI-standard, the drive letters express the priority of the
838 disk. C: should be the hard disk, or a partition on it, with the
839 highest priority. This must therefore be the disk with the highest
840 SCSI-id (e.g. 6) and not the one with the lowest! IBM-BIOS kept the
841 original definition of the SCSI-standard as also industrial- and
842 process-control-machines, like VME-CPUs running under realtime-OSes
843 (e.g. LynxOS, OS9) do.
844
845 If you like to run Linux on your MCA-machine with the same
846 assignment of hard disks as seen from e.g. DOS or OS/2 on your
847 machine, which is in addition conformant to the SCSI-standard, you
848 must say Y here. This is also necessary for MCA-Linux users who want
849 to keep downward compatibility to older releases of the
850 IBM-MCA-SCSI-driver (older than driver-release 2.00 and older than
851 June 1997).
852
853 If you like to have the lowest SCSI-id assigned as drive C:, as
854 modern SCSI-BIOSes do, which does not conform to the standard, but
855 is widespread and common in the PC-world of today, you must say N
856 here. If unsure, say Y.

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

1229 default "8"
1230 ---help---
1231 "Tagged command queuing" is a feature of SCSI-2 which improves
1232 performance: the host adapter can send several SCSI commands to a
1233 device's queue even if previous commands haven't finished yet.
1234 Because the device is intelligent, it can optimize its operations
1235 (like head positioning) based on its own request queue. Some SCSI
1236 devices don't implement this properly; if you want to disable this
1237 feature, enter 0 or 1 here (it doesn't matter which).
1238
1239 The default value is 8 and should be supported by most hard disks.
1240 This value can be overridden from the boot command line using the
1241 'tags' option as follows (example):
1242 'ncr53c8xx=tags:4/t2t3q16/t0u2q10' will set default queue depth to
1243 4, set queue depth to 16 for target 2 and target 3 on controller 0
1244 and set queue depth to 10 for target 0 / lun 2 on controller 1.
1245
1246 The normal answer therefore is to go with the default 8 and to use
1247 a boot command line option for devices that need to use a different
1248 command queue depth.
1249
1250 There is no safe option other than using good SCSI devices.

1257 This option allows you to specify the maximum number of commands

1260 Modern hard disks are able to support 64 tags and even more, but
1261 do not seem to be faster when more than 32 tags are being used.
1262
1263 So, the normal answer here is to go with the default value 32 unless
1264 you are using very large hard disks with large cache (>= 1 MB) that
1265 are able to take advantage of more than 32 tagged commands.
1266

1273 ---help---
1274 The SCSI Parallel Interface-2 Standard defines 5 classes of transfer
1275 rates: FAST-5, FAST-10, FAST-20, FAST-40 and FAST-80. The numbers
1276 are respectively the maximum data transfer rates in mega-transfers
1277 per second for each class. For example, a FAST-20 Wide 16 device is
1278 able to transfer data at 20 million 16 bit packets per second for a
1279 total rate of 40 MB/s.
1280
1281 You may specify 0 if you want to only use asynchronous data
1282 transfers. This is the safest and slowest option. Otherwise, specify
1283 a value between 5 and 80, depending on the capability of your SCSI
1284 controller. The higher the number, the faster the data transfer.
1285 Note that 80 should normally be ok since the driver decreases the
1286 value automatically according to the controller's capabilities.
1287
1288 Your answer to this question is ignored for controllers with NVRAM,
1289 since the driver will get this information from the user set-up. It
1290 also can be overridden using a boot setup option, as follows
1291 (example): 'ncr53c8xx=sync:12' will allow the driver to negotiate
1292 for FAST-20 synchronous data transfer (20 mega-transfers per
1293 second).
1294
1295 The normal answer therefore is not to go with the default but to
1296 select the maximum value 80 allowing the driver to use the maximum
1297 value supported by each controller. If this causes problems with
1298 your SCSI devices, you should come back and decrease the value.
1299
1300 There is no safe option other than using good cabling, right
1301 terminations and SCSI conformant devices.
