14	  If you want to use a SCSI hard disk, SCSI tape drive, SCSI CD-ROM or
15	  any other SCSI device under Linux, say Y and make sure that you know
16	  the name of your SCSI host adapter (the card inside your computer
17	  that "speaks" the SCSI protocol, also called SCSI controller),
18	  because you will be asked for it.
19
20	  You also need to say Y here if you have a device which speaks
21	  the SCSI protocol.  Examples of this include the parallel port
22	  version of the IOMEGA ZIP drive, USB storage devices, Fibre
23	  Channel, FireWire storage and the IDE-SCSI emulation driver.

141	  CD-ROMs or tapes, say Y here. These won't be supported by the kernel
142	  directly, so you need some additional software which knows how to
143	  talk to these devices using the SCSI protocol:
144
145	  For scanners, look at SANE (<http://www.mostang.com/sane/>). For CD
146	  writer software look at Cdrtools
147	  (<http://www.fokus.gmd.de/research/cc/glone/employees/joerg.schilling/private/cdrecord.html>)
148	  and for burning a "disk at once": CDRDAO
149	  (<http://cdrdao.sourceforge.net/>). Cdparanoia is a high
150	  quality digital reader of audio CDs (<http://www.xiph.org/paranoia/>).
151	  For other devices, it's possible that you'll have to write the
152	  driver software yourself. Please read the file

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

203	depends on SCSI
204	---help---
205	  This turns on a logging facility that can be used to debug a number
206	  of SCSI related problems.
207
208	  If you say Y here, no logging output will appear by default, but you
209	  can enable logging by saying Y to "/proc file system support" and
210	  "Sysctl support" below and executing the command
211
212	  echo "scsi log token [level]" > /proc/scsi/scsi
213
214	  at boot time after the /proc file system has been mounted.
215
216	  There are a number of things that can be used for 'token' (you can
217	  find them in the source: <file:drivers/scsi/scsi.c>), and this
218	  allows you to select the types of information you want, and the
219	  level allows you to select the level of verbosity.
220
221	  If you say N here, it may be harder to track down some types of SCSI
222	  problems. If you say Y here your kernel will be somewhat larger, but
223	  there should be no noticeable performance impact as long as you have
224	  logging turned off.

229	help
230	  The SCSI subsystem can probe for devices while the rest of the
231	  system continues booting, and even probe devices on different
232	  busses in parallel, leading to a significant speed-up.
233
234	  If you have built SCSI as modules, enabling this option can
235	  be a problem as the devices may not have been found by the
236	  time your system expects them to have been.  You can load the
237	  scsi_wait_scan module to ensure that all scans have completed.
238	  If you build your SCSI drivers into the kernel, then everything
239	  will work fine if you say Y here.
240
241	  You can override this choice by specifying "scsi_mod.scan=sync"
242	  or async on the kernel's command line.

758	---help---
759	  In the PC-world and in most modern SCSI-BIOS-setups, SCSI-hard disks
760	  are assigned to the drive letters, starting with the lowest SCSI-id
761	  (physical number -- pun) to be drive C:, as seen from DOS and
762	  similar operating systems. When looking into papers describing the
763	  ANSI-SCSI-standard, this assignment of drives appears to be wrong.
764	  The SCSI-standard follows a hardware-hierarchy which says that id 7
765	  has the highest priority and id 0 the lowest. Therefore, the host
766	  adapters are still today everywhere placed as SCSI-id 7 by default.
767	  In the SCSI-standard, the drive letters express the priority of the
768	  disk. C: should be the hard disk, or a partition on it, with the
769	  highest priority. This must therefore be the disk with the highest
770	  SCSI-id (e.g. 6) and not the one with the lowest! IBM-BIOS kept the
771	  original definition of the SCSI-standard as also industrial- and
772	  process-control-machines, like VME-CPUs running under realtime-OSes
773	  (e.g. LynxOS, OS9) do.
774
775	  If you like to run Linux on your MCA-machine with the same
776	  assignment of hard disks as seen from e.g. DOS or OS/2 on your
777	  machine, which is in addition conformant to the SCSI-standard, you
778	  must say Y here. This is also necessary for MCA-Linux users who want
779	  to keep downward compatibility to older releases of the
780	  IBM-MCA-SCSI-driver (older than driver-release 2.00 and older than
781	  June 1997).
782
783	  If you like to have the lowest SCSI-id assigned as drive C:, as
784	  modern SCSI-BIOSes do, which does not conform to the standard, but
785	  is widespread and common in the PC-world of today, you must say N

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

1123	default "8"
1124	---help---
1125	  "Tagged command queuing" is a feature of SCSI-2 which improves
1126	  performance: the host adapter can send several SCSI commands to a
1127	  device's queue even if previous commands haven't finished yet.
1128	  Because the device is intelligent, it can optimize its operations
1129	  (like head positioning) based on its own request queue. Some SCSI
1130	  devices don't implement this properly; if you want to disable this
1131	  feature, enter 0 or 1 here (it doesn't matter which).
1132
1133	  The default value is 8 and should be supported by most hard disks.
1134	  This value can be overridden from the boot command line using the
1135	  'tags' option as follows (example):
1136	  'ncr53c8xx=tags:4/t2t3q16/t0u2q10' will set default queue depth to
1137	  4, set queue depth to 16 for target 2 and target 3 on controller 0
1138	  and set queue depth to 10 for target 0 / lun 2 on controller 1.
1139
1140	  The normal answer therefore is to go with the default 8 and to use
1141	  a boot command line option for devices that need to use a different
1142	  command queue depth.
1143
1144	  There is no safe option other than using good SCSI devices.

1154	  Modern hard disks are able to support 64 tags and even more, but
1155	  do not seem to be faster when more than 32 tags are being used.
1156
1157	  So, the normal answer here is to go with the default value 32 unless
1158	  you are using very large hard disks with large cache (>= 1 MB) that
1159	  are able to take advantage of more than 32 tagged commands.
1160

1167	---help---
1168	  The SCSI Parallel Interface-2 Standard defines 5 classes of transfer
1169	  rates: FAST-5, FAST-10, FAST-20, FAST-40 and FAST-80.  The numbers
1170	  are respectively the maximum data transfer rates in mega-transfers
1171	  per second for each class.  For example, a FAST-20 Wide 16 device is
1172	  able to transfer data at 20 million 16 bit packets per second for a
1173	  total rate of 40 MB/s.
1174
1175	  You may specify 0 if you want to only use asynchronous data
1176	  transfers. This is the safest and slowest option. Otherwise, specify
1177	  a value between 5 and 80, depending on the capability of your SCSI
1178	  controller.  The higher the number, the faster the data transfer.
1179	  Note that 80 should normally be ok since the driver decreases the
1180	  value automatically according to the controller's capabilities.
1181
1182	  Your answer to this question is ignored for controllers with NVRAM,
1183	  since the driver will get this information from the user set-up.  It
1184	  also can be overridden using a boot setup option, as follows
1185	  (example): 'ncr53c8xx=sync:12' will allow the driver to negotiate
1186	  for FAST-20 synchronous data transfer (20 mega-transfers per
1187	  second).
1188
1189	  The normal answer therefore is not to go with the default but to
1190	  select the maximum value 80 allowing the driver to use the maximum
1191	  value supported by each controller. If this causes problems with
1192	  your SCSI devices, you should come back and decrease the value.
1193
