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

769 This is a driver for the old NCR 53c80 series of SCSI controllers
770 on boards using PIO. Most boards such as the Trantor T130 fit this

814 This is support for the IBM SCSI adapter found in many of the PS/2
815 series computers. These machines have an MCA bus, so you need to
816 answer Y to "MCA support" as well and read
817 <file:Documentation/mca.txt>.
818
819 If the adapter isn't found during boot (a common problem for models
820 56, 57, 76, and 77) you'll need to use the 'ibmmcascsi=<pun>' kernel
821 option, where <pun> is the id of the SCSI subsystem (usually 7, but
822 if that doesn't work check your reference diskette). Owners of
823 model 95 with a LED-matrix-display can in addition activate some
824 activity info like under OS/2, but more informative, by setting
825 'ibmmcascsi=display' as an additional kernel parameter. Try "man
826 bootparam" or see the documentation of your boot loader about how to

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

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

1236 default "8"
1237 ---help---
1238 "Tagged command queuing" is a feature of SCSI-2 which improves
1239 performance: the host adapter can send several SCSI commands to a
1240 device's queue even if previous commands haven't finished yet.
1241 Because the device is intelligent, it can optimize its operations
1242 (like head positioning) based on its own request queue. Some SCSI
1243 devices don't implement this properly; if you want to disable this
1244 feature, enter 0 or 1 here (it doesn't matter which).
1245
1246 The default value is 8 and should be supported by most hard disks.
1247 This value can be overridden from the boot command line using the
1248 'tags' option as follows (example):
1249 'ncr53c8xx=tags:4/t2t3q16/t0u2q10' will set default queue depth to
1250 4, set queue depth to 16 for target 2 and target 3 on controller 0
1251 and set queue depth to 10 for target 0 / lun 2 on controller 1.
1252
1253 The normal answer therefore is to go with the default 8 and to use
1254 a boot command line option for devices that need to use a different
1255 command queue depth.
1256
1257 There is no safe option other than using good SCSI devices.

1264 This option allows you to specify the maximum number of commands
1265 that can be queued to any device, when tagged command queuing is
1266 possible. The default value is 32. Minimum is 2, maximum is 64.
1267 Modern hard disks are able to support 64 tags and even more, but
1268 do not seem to be faster when more than 32 tags are being used.
1269
1270 So, the normal answer here is to go with the default value 32 unless
1271 you are using very large hard disks with large cache (>= 1 MB) that
1272 are able to take advantage of more than 32 tagged commands.
1273

1280 ---help---
1281 The SCSI Parallel Interface-2 Standard defines 5 classes of transfer
1282 rates: FAST-5, FAST-10, FAST-20, FAST-40 and FAST-80. The numbers
1283 are respectively the maximum data transfer rates in mega-transfers
1284 per second for each class. For example, a FAST-20 Wide 16 device is
1285 able to transfer data at 20 million 16 bit packets per second for a
1286 total rate of 40 MB/s.
1287
1288 You may specify 0 if you want to only use asynchronous data
1289 transfers. This is the safest and slowest option. Otherwise, specify
1290 a value between 5 and 80, depending on the capability of your SCSI
1291 controller. The higher the number, the faster the data transfer.
1292 Note that 80 should normally be ok since the driver decreases the
1293 value automatically according to the controller's capabilities.
1294
1295 Your answer to this question is ignored for controllers with NVRAM,
1296 since the driver will get this information from the user set-up. It
1297 also can be overridden using a boot setup option, as follows
1298 (example): 'ncr53c8xx=sync:12' will allow the driver to negotiate
1299 for FAST-20 synchronous data transfer (20 mega-transfers per
1300 second).
1301
1302 The normal answer therefore is not to go with the default but to
1303 select the maximum value 80 allowing the driver to use the maximum
1304 value supported by each controller. If this causes problems with
1305 your SCSI devices, you should come back and decrease the value.
1306
1307 There is no safe option other than using good cabling, right
1308 terminations and SCSI conformant devices.

1576 On Power Macintoshes (and clones) where the MESH SCSI bus adaptor
1577 drives a bus which is entirely internal to the machine (such as the
1578 7500, 7600, 8500, etc.), the MESH is capable of synchronous
1579 operation at up to 10 MB/s. On machines where the SCSI bus
1580 controlled by the MESH can have external devices connected, it is
1581 usually rated at 5 MB/s. 5 is a safe value here unless you know the
1582 MESH SCSI bus is internal only; in that case you can say 10. Say 0
