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.

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

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

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

779 This is a driver for the old NCR 53c80 series of SCSI controllers
780 on boards using memory mapped I/O.
781 It is explained in section 3.8 of the SCSI-HOWTO, available from
782 <http://www.tldp.org/docs.html#howto>. If it doesn't work out
783 of the box, you may have to change some settings in

793 This enables certain optimizations for the NCR53c400 SCSI cards.
794 You might as well try it out. Note that this driver will only probe
795 for the Trantor T130B in its default configuration; you might have
796 to pass a command line option to the kernel at boot time if it does
797 not detect your card. See the file

804 This is support for the IBM SCSI adapter found in many of the PS/2
805 series computers. These machines have an MCA bus, so you need to
806 answer Y to "MCA support" as well and read
807 <file:Documentation/mca.txt>.
808
809 If the adapter isn't found during boot (a common problem for models
810 56, 57, 76, and 77) you'll need to use the 'ibmmcascsi=<pun>' kernel
811 option, where <pun> is the id of the SCSI subsystem (usually 7, but
812 if that doesn't work check your reference diskette). Owners of
813 model 95 with a LED-matrix-display can in addition activate some
814 activity info like under OS/2, but more informative, by setting
815 'ibmmcascsi=display' as an additional kernel parameter. Try "man
816 bootparam" or see the documentation of your boot loader about how to
817 pass options to the kernel.

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

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

1225 default "8"
1226 ---help---
1227 "Tagged command queuing" is a feature of SCSI-2 which improves
1228 performance: the host adapter can send several SCSI commands to a
1229 device's queue even if previous commands haven't finished yet.
1230 Because the device is intelligent, it can optimize its operations
1231 (like head positioning) based on its own request queue. Some SCSI
1232 devices don't implement this properly; if you want to disable this
1233 feature, enter 0 or 1 here (it doesn't matter which).
1234
1235 The default value is 8 and should be supported by most hard disks.
1236 This value can be overridden from the boot command line using the
1237 'tags' option as follows (example):
1238 'ncr53c8xx=tags:4/t2t3q16/t0u2q10' will set default queue depth to
1239 4, set queue depth to 16 for target 2 and target 3 on controller 0
1240 and set queue depth to 10 for target 0 / lun 2 on controller 1.
1241
1242 The normal answer therefore is to go with the default 8 and to use
1243 a boot command line option for devices that need to use a different
1244 command queue depth.
1245
1246 There is no safe option other than using good SCSI devices.

1253 This option allows you to specify the maximum number of commands
1254 that can be queued to any device, when tagged command queuing is
1255 possible. The default value is 32. Minimum is 2, maximum is 64.
1256 Modern hard disks are able to support 64 tags and even more, but
1257 do not seem to be faster when more than 32 tags are being used.
1258
1259 So, the normal answer here is to go with the default value 32 unless
1260 you are using very large hard disks with large cache (>= 1 MB) that
1261 are able to take advantage of more than 32 tagged commands.
1262

1269 ---help---
1270 The SCSI Parallel Interface-2 Standard defines 5 classes of transfer
1271 rates: FAST-5, FAST-10, FAST-20, FAST-40 and FAST-80. The numbers
1272 are respectively the maximum data transfer rates in mega-transfers
1273 per second for each class. For example, a FAST-20 Wide 16 device is
1274 able to transfer data at 20 million 16 bit packets per second for a
1275 total rate of 40 MB/s.
1276
1277 You may specify 0 if you want to only use asynchronous data
1278 transfers. This is the safest and slowest option. Otherwise, specify
1279 a value between 5 and 80, depending on the capability of your SCSI
1280 controller. The higher the number, the faster the data transfer.
1281 Note that 80 should normally be ok since the driver decreases the
1282 value automatically according to the controller's capabilities.
1283
1284 Your answer to this question is ignored for controllers with NVRAM,
1285 since the driver will get this information from the user set-up. It
1286 also can be overridden using a boot setup option, as follows
1287 (example): 'ncr53c8xx=sync:12' will allow the driver to negotiate
1288 for FAST-20 synchronous data transfer (20 mega-transfers per
1289 second).
1290
1291 The normal answer therefore is not to go with the default but to
1292 select the maximum value 80 allowing the driver to use the maximum
1293 value supported by each controller. If this causes problems with
1294 your SCSI devices, you should come back and decrease the value.
1295
1296 There is no safe option other than using good cabling, right
1297 terminations and SCSI conformant devices.
