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.
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

148 CD-ROMs or tapes, say Y here. These won't be supported by the kernel
149 directly, so you need some additional software which knows how to
150 talk to these devices using the SCSI protocol:

223 If you say Y here, no logging output will appear by default, but you
224 can enable logging by saying Y to "/proc file system support" and
225 "Sysctl support" below and executing the command
227 echo "scsi log token [level]" > /proc/scsi/scsi
229 at boot time after the /proc file system has been mounted.
231 There are a number of things that can be used for 'token' (you can
232 find them in the source: <file:drivers/scsi/scsi.c>), and this
233 allows you to select the types of information you want, and the
234 level allows you to select the level of verbosity.
236 If you say N here, it may be harder to track down some types of SCSI
237 problems. If you say Y here your kernel will be somewhat larger, but
238 there should be no noticeable performance impact as long as you have
239 logging turned off.

249 If you have built SCSI as modules, enabling this option can
250 be a problem as the devices may not have been found by the
251 time your system expects them to have been. You can load the
252 scsi_wait_scan module to ensure that all scans have completed.
253 If you build your SCSI drivers into the kernel, then everything
254 will work fine if you say Y here.

474 possible, people should use the new Adaptec written driver instead
475 of this one. This driver will eventually be phased out entirely.
477 This is support for the various aic7xxx based Adaptec SCSI

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.
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

822 config IBMMCA_SCSI_ORDER_STANDARD
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.
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).
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.

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.

1224 int "default tagged command queue depth"
1225 depends on SCSI_ZALON || SCSI_NCR_Q720
1226 default "8"
1227 ---help---
1228 "Tagged command queuing" is a feature of SCSI-2 which improves
1229 performance: the host adapter can send several SCSI commands to a
1230 device's queue even if previous commands haven't finished yet.
1231 Because the device is intelligent, it can optimize its operations
1232 (like head positioning) based on its own request queue. Some SCSI
1233 devices don't implement this properly; if you want to disable this
1234 feature, enter 0 or 1 here (it doesn't matter which).
1236 The default value is 8 and should be supported by most hard disks.
1237 This value can be overridden from the boot command line using the
1238 'tags' option as follows (example):
1239 'ncr53c8xx=tags:4/t2t3q16/t0u2q10' will set default queue depth to
1240 4, set queue depth to 16 for target 2 and target 3 on controller 0
1241 and set queue depth to 10 for target 0 / lun 2 on controller 1.
1243 The normal answer therefore is to go with the default 8 and to use
1244 a boot command line option for devices that need to use a different
1245 command queue depth.
1247 There is no safe option other than using good SCSI devices.

1253 ---help---
1254 This option allows you to specify the maximum number of commands
1255 that can be queued to any device, when tagged command queuing is
1256 possible. The default value is 32. Minimum is 2, maximum is 64.
1257 Modern hard disks are able to support 64 tags and even more, but
1258 do not seem to be faster when more than 32 tags are being used.
1260 So, the normal answer here is to go with the default value 32 unless
1261 you are using very large hard disks with large cache (>= 1 MB) that
1262 are able to take advantage of more than 32 tagged commands.
1264 There is no safe option and the default answer is recommended.

1267 int "synchronous transfers frequency in MHz"
1268 depends on SCSI_ZALON || SCSI_NCR_Q720

1270 ---help---
1271 The SCSI Parallel Interface-2 Standard defines 5 classes of transfer
1272 rates: FAST-5, FAST-10, FAST-20, FAST-40 and FAST-80. The numbers
1273 are respectively the maximum data transfer rates in mega-transfers
1274 per second for each class. For example, a FAST-20 Wide 16 device is
1275 able to transfer data at 20 million 16 bit packets per second for a
1276 total rate of 40 MB/s.
1278 You may specify 0 if you want to only use asynchronous data
1279 transfers. This is the safest and slowest option. Otherwise, specify
1280 a value between 5 and 80, depending on the capability of your SCSI
1281 controller. The higher the number, the faster the data transfer.
1282 Note that 80 should normally be ok since the driver decreases the
1283 value automatically according to the controller's capabilities.
1285 Your answer to this question is ignored for controllers with NVRAM,
1286 since the driver will get this information from the user set-up. It
1287 also can be overridden using a boot setup option, as follows
1288 (example): 'ncr53c8xx=sync:12' will allow the driver to negotiate
1289 for FAST-20 synchronous data transfer (20 mega-transfers per
1290 second).
1292 The normal answer therefore is not to go with the default but to
1293 select the maximum value 80 allowing the driver to use the maximum
1294 value supported by each controller. If this causes problems with
1295 your SCSI devices, you should come back and decrease the value.
1297 There is no safe option other than using good cabling, right
1298 terminations and SCSI conformant devices.

1651 Support for various NCR53c710-based SCSI controllers on Zorro
1652 expansion boards for the Amiga.
1653 This includes:
1654 - the Amiga 4091 Zorro III SCSI-2 controller,
1655 - the MacroSystem Development's WarpEngine Amiga SCSI-2 controller
1656 (info at
1657 <http://www.lysator.liu.se/amiga/ar/guide/ar310.guide?FEATURE5>),
1658 - the SCSI controller on the Phase5 Blizzard PowerUP 603e+
1659 accelerator card for the Amiga 1200,
1660 - the SCSI controller on the GVP Turbo 040/060 accelerator.

1667 ---help---
1668 If you have an Atari with built-in NCR5380 SCSI controller (TT,
1669 Falcon, ...) say Y to get it supported. Of course also, if you have
1670 a compatible SCSI controller (e.g. for Medusa).
1672 To compile this driver as a module, choose M here: the
1673 module will be called atari_scsi.
1675 This driver supports both styles of NCR integration into the
1676 system: the TT style (separate DMA), and the Falcon style (via
1677 ST-DMA, replacing ACSI). It does NOT support other schemes, like
1678 in the Hades (without DMA).
1680 config ATARI_SCSI_TOSHIBA_DELAY

1682 depends on ATARI_SCSI
1683 help
1684 This option increases the delay after a SCSI arbitration to
1685 accommodate some flaky Toshiba CD-ROM drives. Say Y if you intend to
1686 use a Toshiba CD-ROM drive; otherwise, the option is not needed and
1687 would impact performance a bit, so say N.

1692 help
1693 Reset the devices on your Atari whenever it boots. This makes the
1694 boot process fractionally longer but may assist recovery from errors
1695 that leave the devices with SCSI operations partway completed.
