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

147	  CD-ROMs or tapes, say Y here. These won't be supported by the kernel
148	  directly, so you need some additional software which knows how to
149	  talk to these devices using the SCSI protocol:
150
151	  For scanners, look at SANE (<http://www.mostang.com/sane/>). For CD
152	  writer software look at Cdrtools
153	  (<http://www.fokus.gmd.de/research/cc/glone/employees/joerg.schilling/private/cdrecord.html>)
154	  and for burning a "disk at once": CDRDAO

156	  quality digital reader of audio CDs (<http://www.xiph.org/paranoia/>).
157	  For other devices, it's possible that you'll have to write the

193	  can say Y here to force the SCSI driver to probe for multiple LUNs.
194	  A SCSI device with multiple LUNs acts logically like multiple SCSI
195	  devices. The vast majority of SCSI devices have only one LUN, and
196	  so most people can say N here. The max_luns boot/module parameter
197	  allows to override this setting.

211	  This turns on a logging facility that can be used to debug a number
212	  of SCSI related problems.
213
214	  If you say Y here, no logging output will appear by default, but you
215	  can enable logging by saying Y to "/proc file system support" and
216	  "Sysctl support" below and executing the command
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.

239
240	  If you have built SCSI as modules, enabling this option can
241	  be a problem as the devices may not have been found by the
242	  time your system expects them to have been.  You can load the
243	  scsi_wait_scan module to ensure that all scans have completed.
244	  If you build your SCSI drivers into the kernel, then everything
245	  will work fine if you say Y here.

778	---help---
779	  In the PC-world and in most modern SCSI-BIOS-setups, SCSI-hard disks
780	  are assigned to the drive letters, starting with the lowest SCSI-id
781	  (physical number -- pun) to be drive C:, as seen from DOS and
782	  similar operating systems. When looking into papers describing the
783	  ANSI-SCSI-standard, this assignment of drives appears to be wrong.
784	  The SCSI-standard follows a hardware-hierarchy which says that id 7
785	  has the highest priority and id 0 the lowest. Therefore, the host
786	  adapters are still today everywhere placed as SCSI-id 7 by default.
787	  In the SCSI-standard, the drive letters express the priority of the
788	  disk. C: should be the hard disk, or a partition on it, with the
789	  highest priority. This must therefore be the disk with the highest
790	  SCSI-id (e.g. 6) and not the one with the lowest! IBM-BIOS kept the
791	  original definition of the SCSI-standard as also industrial- and
792	  process-control-machines, like VME-CPUs running under realtime-OSes
793	  (e.g. LynxOS, OS9) do.
794
795	  If you like to run Linux on your MCA-machine with the same
796	  assignment of hard disks as seen from e.g. DOS or OS/2 on your
797	  machine, which is in addition conformant to the SCSI-standard, you
798	  must say Y here. This is also necessary for MCA-Linux users who want
799	  to keep downward compatibility to older releases of the
800	  IBM-MCA-SCSI-driver (older than driver-release 2.00 and older than
801	  June 1997).
802
803	  If you like to have the lowest SCSI-id assigned as drive C:, as
804	  modern SCSI-BIOSes do, which does not conform to the standard, but
805	  is widespread and common in the PC-world of today, you must say N
806	  here. If unsure, say Y.

813	  However, some devices exist, like special-control-devices,
814	  SCSI-CNC-machines, SCSI-printer or scanners of older type, that do
815	  not reset when switched on. If you say Y here, each device connected
816	  to your SCSI-bus will be issued a reset-command after it has been
817	  probed, while the kernel is booting. This may cause problems with
818	  more modern devices, like hard disks, which do not appreciate these
819	  reset commands, and can cause your system to hang. So say Y only if

1148	default "8"
1149	---help---
1150	  "Tagged command queuing" is a feature of SCSI-2 which improves
1151	  performance: the host adapter can send several SCSI commands to a
1152	  device's queue even if previous commands haven't finished yet.
1153	  Because the device is intelligent, it can optimize its operations
1154	  (like head positioning) based on its own request queue. Some SCSI
1155	  devices don't implement this properly; if you want to disable this
1156	  feature, enter 0 or 1 here (it doesn't matter which).
1157
1158	  The default value is 8 and should be supported by most hard disks.
1159	  This value can be overridden from the boot command line using the
1160	  'tags' option as follows (example):
1161	  'ncr53c8xx=tags:4/t2t3q16/t0u2q10' will set default queue depth to
1162	  4, set queue depth to 16 for target 2 and target 3 on controller 0
1163	  and set queue depth to 10 for target 0 / lun 2 on controller 1.
1164
1165	  The normal answer therefore is to go with the default 8 and to use
1166	  a boot command line option for devices that need to use a different
1167	  command queue depth.
1168
1169	  There is no safe option other than using good SCSI devices.

1179	  Modern hard disks are able to support 64 tags and even more, but
1180	  do not seem to be faster when more than 32 tags are being used.
1181
1182	  So, the normal answer here is to go with the default value 32 unless
1183	  you are using very large hard disks with large cache (>= 1 MB) that
1184	  are able to take advantage of more than 32 tagged commands.
1185

1192	---help---
1193	  The SCSI Parallel Interface-2 Standard defines 5 classes of transfer
1194	  rates: FAST-5, FAST-10, FAST-20, FAST-40 and FAST-80.  The numbers
1195	  are respectively the maximum data transfer rates in mega-transfers
1196	  per second for each class.  For example, a FAST-20 Wide 16 device is
1197	  able to transfer data at 20 million 16 bit packets per second for a
1198	  total rate of 40 MB/s.
1199
1200	  You may specify 0 if you want to only use asynchronous data
1201	  transfers. This is the safest and slowest option. Otherwise, specify
1202	  a value between 5 and 80, depending on the capability of your SCSI
1203	  controller.  The higher the number, the faster the data transfer.
1204	  Note that 80 should normally be ok since the driver decreases the
1205	  value automatically according to the controller's capabilities.
1206
1207	  Your answer to this question is ignored for controllers with NVRAM,
1208	  since the driver will get this information from the user set-up.  It
1209	  also can be overridden using a boot setup option, as follows
1210	  (example): 'ncr53c8xx=sync:12' will allow the driver to negotiate
1211	  for FAST-20 synchronous data transfer (20 mega-transfers per
1212	  second).
1213
1214	  The normal answer therefore is not to go with the default but to
1215	  select the maximum value 80 allowing the driver to use the maximum
1216	  value supported by each controller. If this causes problems with
1217	  your SCSI devices, you should come back and decrease the value.
1218

1428	  another driver for the same hardware: "UltraStor SCSI support",

1439	  This is a feature of SCSI-2 which improves performance: the host

1448	  This option enables elevator sorting for all probed SCSI disks and
1449	  CD-ROMs. It definitely reduces the average seek distance when doing
1450	  random seeks, but this does not necessarily result in a noticeable
1451	  performance improvement: your mileage may vary...
