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

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

473 WARNING This driver is an older aic7xxx driver and is no longer
474 under active development. Adaptec, Inc. is writing a new driver to
475 take the place of this one, and it is recommended that whenever
476 possible, people should use the new Adaptec written driver instead
477 of this one. This driver will eventually be phased out entirely.
478
479 This is support for the various aic7xxx based Adaptec SCSI
480 controllers. These include the 274x EISA cards; 284x VLB cards;
481 2902, 2910, 293x, 294x, 394x, 3985 and several other PCI and
482 motherboard based SCSI controllers from Adaptec. It does not support
483 the AAA-13x RAID controllers from Adaptec, nor will it likely ever
484 support them. It does not support the 2920 cards from Adaptec that
485 use the Future Domain SCSI controller chip. For those cards, you
486 need the "Future Domain 16xx SCSI support" driver.
487
488 In general, if the controller is based on an Adaptec SCSI controller
489 chip from the aic777x series or the aic78xx series, this driver
490 should work. The only exception is the 7810 which is specifically
491 not supported (that's the RAID controller chip on the AAA-13x
492 cards).
493
494 Note that the AHA2920 SCSI host adapter is *not* supported by this
495 driver; choose "Future Domain 16xx SCSI support" instead if you have
496 one of those.
497
498 Information on the configuration options for this controller can be
499 found by checking the help file for each of the available
500 configuration options. You should read
501 <file:Documentation/scsi/aic7xxx_old.txt> at a minimum before
502 contacting the maintainer with any questions. The SCSI-HOWTO,

780 This is a driver for the old NCR 53c80 series of SCSI controllers
781 on boards using PIO. Most boards such as the Trantor T130 fit this
782 category, along with a large number of ISA 8bit controllers shipped
783 for free with SCSI scanners. If you have a PAS16, T128 or DMX3191
784 you should select the specific driver for that card rather than
785 generic 5380 support.

825 This is support for the IBM SCSI adapter found in many of the PS/2
826 series computers. These machines have an MCA bus, so you need to
827 answer Y to "MCA support" as well and read
828 <file:Documentation/mca.txt>.
829
830 If the adapter isn't found during boot (a common problem for models
831 56, 57, 76, and 77) you'll need to use the 'ibmmcascsi=<pun>' kernel
832 option, where <pun> is the id of the SCSI subsystem (usually 7, but
833 if that doesn't work check your reference diskette). Owners of
834 model 95 with a LED-matrix-display can in addition activate some
835 activity info like under OS/2, but more informative, by setting
836 'ibmmcascsi=display' as an additional kernel parameter. Try "man
837 bootparam" or see the documentation of your boot loader about how to
838 pass options to the kernel.

843config IBMMCA_SCSI_ORDER_STANDARD
844 bool "Standard SCSI-order"
845 depends on SCSI_IBMMCA
846 ---help---
847 In the PC-world and in most modern SCSI-BIOS-setups, SCSI-hard disks
848 are assigned to the drive letters, starting with the lowest SCSI-id
849 (physical number -- pun) to be drive C:, as seen from DOS and
850 similar operating systems. When looking into papers describing the
851 ANSI-SCSI-standard, this assignment of drives appears to be wrong.
852 The SCSI-standard follows a hardware-hierarchy which says that id 7
853 has the highest priority and id 0 the lowest. Therefore, the host
854 adapters are still today everywhere placed as SCSI-id 7 by default.
855 In the SCSI-standard, the drive letters express the priority of the
856 disk. C: should be the hard disk, or a partition on it, with the
857 highest priority. This must therefore be the disk with the highest
858 SCSI-id (e.g. 6) and not the one with the lowest! IBM-BIOS kept the
859 original definition of the SCSI-standard as also industrial- and
860 process-control-machines, like VME-CPUs running under realtime-OSes
861 (e.g. LynxOS, OS9) do.
862
863 If you like to run Linux on your MCA-machine with the same
864 assignment of hard disks as seen from e.g. DOS or OS/2 on your
865 machine, which is in addition conformant to the SCSI-standard, you
866 must say Y here. This is also necessary for MCA-Linux users who want
867 to keep downward compatibility to older releases of the
868 IBM-MCA-SCSI-driver (older than driver-release 2.00 and older than
869 June 1997).
870
871 If you like to have the lowest SCSI-id assigned as drive C:, as
872 modern SCSI-BIOSes do, which does not conform to the standard, but
873 is widespread and common in the PC-world of today, you must say N
874 here. If unsure, say Y.

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

1247 default "8"
1248 ---help---
1249 "Tagged command queuing" is a feature of SCSI-2 which improves
1250 performance: the host adapter can send several SCSI commands to a
1251 device's queue even if previous commands haven't finished yet.
1252 Because the device is intelligent, it can optimize its operations
1253 (like head positioning) based on its own request queue. Some SCSI
1254 devices don't implement this properly; if you want to disable this
1255 feature, enter 0 or 1 here (it doesn't matter which).
1256
1257 The default value is 8 and should be supported by most hard disks.
1258 This value can be overridden from the boot command line using the
1259 'tags' option as follows (example):
1260 'ncr53c8xx=tags:4/t2t3q16/t0u2q10' will set default queue depth to
1261 4, set queue depth to 16 for target 2 and target 3 on controller 0
1262 and set queue depth to 10 for target 0 / lun 2 on controller 1.
1263
1264 The normal answer therefore is to go with the default 8 and to use
1265 a boot command line option for devices that need to use a different
1266 command queue depth.
1267
1268 There is no safe option other than using good SCSI devices.

1278 Modern hard disks are able to support 64 tags and even more, but
1279 do not seem to be faster when more than 32 tags are being used.
1280
1281 So, the normal answer here is to go with the default value 32 unless
1282 you are using very large hard disks with large cache (>= 1 MB) that
1283 are able to take advantage of more than 32 tagged commands.
1284

1291 ---help---
1292 The SCSI Parallel Interface-2 Standard defines 5 classes of transfer
1293 rates: FAST-5, FAST-10, FAST-20, FAST-40 and FAST-80. The numbers
1294 are respectively the maximum data transfer rates in mega-transfers
1295 per second for each class. For example, a FAST-20 Wide 16 device is
1296 able to transfer data at 20 million 16 bit packets per second for a
1297 total rate of 40 MB/s.
1298
1299 You may specify 0 if you want to only use asynchronous data
1300 transfers. This is the safest and slowest option. Otherwise, specify
1301 a value between 5 and 80, depending on the capability of your SCSI
1302 controller. The higher the number, the faster the data transfer.
1303 Note that 80 should normally be ok since the driver decreases the
1304 value automatically according to the controller's capabilities.
1305
1306 Your answer to this question is ignored for controllers with NVRAM,
1307 since the driver will get this information from the user set-up. It
1308 also can be overridden using a boot setup option, as follows
1309 (example): 'ncr53c8xx=sync:12' will allow the driver to negotiate
1310 for FAST-20 synchronous data transfer (20 mega-transfers per
1311 second).
1312
1313 The normal answer therefore is not to go with the default but to
1314 select the maximum value 80 allowing the driver to use the maximum
1315 value supported by each controller. If this causes problems with
1316 your SCSI devices, you should come back and decrease the value.
1317
1318 There is no safe option other than using good cabling, right
1319 terminations and SCSI conformant devices.

1588 drives a bus which is entirely internal to the machine (such as the
1589 7500, 7600, 8500, etc.), the MESH is capable of synchronous
1590 operation at up to 10 MB/s. On machines where the SCSI bus
1591 controlled by the MESH can have external devices connected, it is
1592 usually rated at 5 MB/s. 5 is a safe value here unless you know the
