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

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

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

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

1181 "Tagged command queuing" is a feature of SCSI-2 which improves
1182 performance: the host adapter can send several SCSI commands to a
1183 device's queue even if previous commands haven't finished yet.
1184 Because the device is intelligent, it can optimize its operations
1185 (like head positioning) based on its own request queue. Some SCSI
1186 devices don't implement this properly; if you want to disable this
1187 feature, enter 0 or 1 here (it doesn't matter which).
1188
1189 The default value is 8 and should be supported by most hard disks.
1190 This value can be overridden from the boot command line using the
1191 'tags' option as follows (example):
1192 'ncr53c8xx=tags:4/t2t3q16/t0u2q10' will set default queue depth to
1193 4, set queue depth to 16 for target 2 and target 3 on controller 0
1194 and set queue depth to 10 for target 0 / lun 2 on controller 1.
1195
1196 The normal answer therefore is to go with the default 8 and to use
1197 a boot command line option for devices that need to use a different
1198 command queue depth.

1211 do not seem to be faster when more than 32 tags are being used.
1212
1213 So, the normal answer here is to go with the default value 32 unless
1214 you are using very large hard disks with large cache (>= 1 MB) that
1215 are able to take advantage of more than 32 tagged commands.
1216
1217 There is no safe option and the default answer is recommended.

1223 ---help---
1224 The SCSI Parallel Interface-2 Standard defines 5 classes of transfer
1225 rates: FAST-5, FAST-10, FAST-20, FAST-40 and FAST-80. The numbers
1226 are respectively the maximum data transfer rates in mega-transfers
1227 per second for each class. For example, a FAST-20 Wide 16 device is
1228 able to transfer data at 20 million 16 bit packets per second for a
1229 total rate of 40 MB/s.
1230
1231 You may specify 0 if you want to only use asynchronous data
1232 transfers. This is the safest and slowest option. Otherwise, specify
1233 a value between 5 and 80, depending on the capability of your SCSI
1234 controller. The higher the number, the faster the data transfer.
1235 Note that 80 should normally be ok since the driver decreases the
1236 value automatically according to the controller's capabilities.
1237
1238 Your answer to this question is ignored for controllers with NVRAM,
1239 since the driver will get this information from the user set-up. It
1240 also can be overridden using a boot setup option, as follows
1241 (example): 'ncr53c8xx=sync:12' will allow the driver to negotiate
1242 for FAST-20 synchronous data transfer (20 mega-transfers per
1243 second).
1244
1245 The normal answer therefore is not to go with the default but to
1246 select the maximum value 80 allowing the driver to use the maximum
1247 value supported by each controller. If this causes problems with
1248 your SCSI devices, you should come back and decrease the value.
1249
1250 There is no safe option other than using good cabling, right
1251 terminations and SCSI conformant devices.

1621 If you have an Atari with built-in NCR5380 SCSI controller (TT,
1622 Falcon, ...) say Y to get it supported. Of course also, if you have
1623 a compatible SCSI controller (e.g. for Medusa).
1624
1625 To compile this driver as a module, choose M here: the
1626 module will be called atari_scsi.
1627
1628 This driver supports both styles of NCR integration into the
1629 system: the TT style (separate DMA), and the Falcon style (via
1630 ST-DMA, replacing ACSI). It does NOT support other schemes, like
1631 in the Hades (without DMA).

1637 This option increases the delay after a SCSI arbitration to
1638 accommodate some flaky Toshiba CD-ROM drives. Say Y if you intend to
1639 use a Toshiba CD-ROM drive; otherwise, the option is not needed and
1640 would impact performance a bit, so say N.

1646 Reset the devices on your Atari whenever it boots. This makes the
1647 boot process fractionally longer but may assist recovery from errors
1648 that leave the devices with SCSI operations partway completed.
