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.

152 writer software look at Cdrtools

217
218 echo "scsi log token [level]" > /proc/scsi/scsi
219
220 at boot time after the /proc file system has been mounted.
221
222 There are a number of things that can be used for 'token' (you can
223 find them in the source: <file:drivers/scsi/scsi.c>), and this
224 allows you to select the types of information you want, and the
225 level allows you to select the level of verbosity.
226
227 If you say N here, it may be harder to track down some types of SCSI
228 problems. If you say Y here your kernel will be somewhat larger, but
229 there should be no noticeable performance impact as long as you have
230 logging turned off.

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

494 one of those.

812 In the PC-world and in most modern SCSI-BIOS-setups, SCSI-hard disks
813 are assigned to the drive letters, starting with the lowest SCSI-id
814 (physical number -- pun) to be drive C:, as seen from DOS and
815 similar operating systems. When looking into papers describing the
816 ANSI-SCSI-standard, this assignment of drives appears to be wrong.
817 The SCSI-standard follows a hardware-hierarchy which says that id 7
818 has the highest priority and id 0 the lowest. Therefore, the host
819 adapters are still today everywhere placed as SCSI-id 7 by default.
820 In the SCSI-standard, the drive letters express the priority of the
821 disk. C: should be the hard disk, or a partition on it, with the
822 highest priority. This must therefore be the disk with the highest
823 SCSI-id (e.g. 6) and not the one with the lowest! IBM-BIOS kept the
824 original definition of the SCSI-standard as also industrial- and
825 process-control-machines, like VME-CPUs running under realtime-OSes
826 (e.g. LynxOS, OS9) do.

828 If you like to run Linux on your MCA-machine with the same
829 assignment of hard disks as seen from e.g. DOS or OS/2 on your
830 machine, which is in addition conformant to the SCSI-standard, you
831 must say Y here. This is also necessary for MCA-Linux users who want
832 to keep downward compatibility to older releases of the
833 IBM-MCA-SCSI-driver (older than driver-release 2.00 and older than
834 June 1997).
835
836 If you like to have the lowest SCSI-id assigned as drive C:, as
837 modern SCSI-BIOSes do, which does not conform to the standard, but
838 is widespread and common in the PC-world of today, you must say N
839 here. If unsure, say Y.

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

1183 ---help---
1184 "Tagged command queuing" is a feature of SCSI-2 which improves
1185 performance: the host adapter can send several SCSI commands to a
1186 device's queue even if previous commands haven't finished yet.
1187 Because the device is intelligent, it can optimize its operations
1188 (like head positioning) based on its own request queue. Some SCSI
1189 devices don't implement this properly; if you want to disable this
1190 feature, enter 0 or 1 here (it doesn't matter which).
1191
1192 The default value is 8 and should be supported by most hard disks.
1193 This value can be overridden from the boot command line using the
1194 'tags' option as follows (example):
1195 'ncr53c8xx=tags:4/t2t3q16/t0u2q10' will set default queue depth to
1196 4, set queue depth to 16 for target 2 and target 3 on controller 0
1197 and set queue depth to 10 for target 0 / lun 2 on controller 1.
1198
1199 The normal answer therefore is to go with the default 8 and to use
1200 a boot command line option for devices that need to use a different
1201 command queue depth.
1202
1203 There is no safe option other than using good SCSI devices.

1214 do not seem to be faster when more than 32 tags are being used.

1236 a value between 5 and 80, depending on the capability of your SCSI
1237 controller. The higher the number, the faster the data transfer.
1238 Note that 80 should normally be ok since the driver decreases the
1239 value automatically according to the controller's capabilities.
1240
1241 Your answer to this question is ignored for controllers with NVRAM,
1242 since the driver will get this information from the user set-up. It
1243 also can be overridden using a boot setup option, as follows
1244 (example): 'ncr53c8xx=sync:12' will allow the driver to negotiate
1245 for FAST-20 synchronous data transfer (20 mega-transfers per
1246 second).
1247
1248 The normal answer therefore is not to go with the default but to
1249 select the maximum value 80 allowing the driver to use the maximum
1250 value supported by each controller. If this causes problems with
1251 your SCSI devices, you should come back and decrease the value.
1252
1253 There is no safe option other than using good cabling, right
1254 terminations and SCSI conformant devices.
