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

30 However, do not compile this as a module if your root file system
31 (the one containing the directory /) is located on a SCSI device.

228 at boot time after the /proc file system has been mounted.
229
230 There are a number of things that can be used for 'token' (you can

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

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

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

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

1198 feature, enter 0 or 1 here (it doesn't matter which).
1199
1200 The default value is 8 and should be supported by most hard disks.
1201 This value can be overridden from the boot command line using the
1202 'tags' option as follows (example):
1203 'ncr53c8xx=tags:4/t2t3q16/t0u2q10' will set default queue depth to
1204 4, set queue depth to 16 for target 2 and target 3 on controller 0
1205 and set queue depth to 10 for target 0 / lun 2 on controller 1.
1206
1207 The normal answer therefore is to go with the default 8 and to use
1208 a boot command line option for devices that need to use a different
1209 command queue depth.
1210
1211 There is no safe option other than using good SCSI devices.

1218 This option allows you to specify the maximum number of commands
1219 that can be queued to any device, when tagged command queuing is
1220 possible. The default value is 32. Minimum is 2, maximum is 64.
1221 Modern hard disks are able to support 64 tags and even more, but
1222 do not seem to be faster when more than 32 tags are being used.
1223
1224 So, the normal answer here is to go with the default value 32 unless
1225 you are using very large hard disks with large cache (>= 1 MB) that
1226 are able to take advantage of more than 32 tagged commands.
1227

1234 ---help---
1235 The SCSI Parallel Interface-2 Standard defines 5 classes of transfer
1236 rates: FAST-5, FAST-10, FAST-20, FAST-40 and FAST-80. The numbers
1237 are respectively the maximum data transfer rates in mega-transfers
1238 per second for each class. For example, a FAST-20 Wide 16 device is
1239 able to transfer data at 20 million 16 bit packets per second for a
1240 total rate of 40 MB/s.
1241
1242 You may specify 0 if you want to only use asynchronous data
1243 transfers. This is the safest and slowest option. Otherwise, specify
1244 a value between 5 and 80, depending on the capability of your SCSI
1245 controller. The higher the number, the faster the data transfer.
1246 Note that 80 should normally be ok since the driver decreases the
1247 value automatically according to the controller's capabilities.
1248
1249 Your answer to this question is ignored for controllers with NVRAM,
1250 since the driver will get this information from the user set-up. It
1251 also can be overridden using a boot setup option, as follows
1252 (example): 'ncr53c8xx=sync:12' will allow the driver to negotiate
1253 for FAST-20 synchronous data transfer (20 mega-transfers per
1254 second).
1255
1256 The normal answer therefore is not to go with the default but to
1257 select the maximum value 80 allowing the driver to use the maximum
1258 value supported by each controller. If this causes problems with
1259 your SCSI devices, you should come back and decrease the value.
1260
1261 There is no safe option other than using good cabling, right
1262 terminations and SCSI conformant devices.

1632 If you have an Atari with built-in NCR5380 SCSI controller (TT,
1633 Falcon, ...) say Y to get it supported. Of course also, if you have
1634 a compatible SCSI controller (e.g. for Medusa).

1636 To compile this driver as a module, choose M here: the
1637 module will be called atari_scsi.
1638
1639 This driver supports both styles of NCR integration into the
1640 system: the TT style (separate DMA), and the Falcon style (via
1641 ST-DMA, replacing ACSI). It does NOT support other schemes, like
1642 in the Hades (without DMA).
