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

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	  If you have built SCSI as modules, enabling this option can
234	  be a problem as the devices may not have been found by the
235	  time your system expects them to have been.  You can load the
236	  scsi_wait_scan module to ensure that all scans have completed.
237	  If you build your SCSI drivers into the kernel, then everything
238	  will work fine if you say Y here.
239
240	  You can override this choice by specifying scsi_mod.scan="sync"
241	  or "async" on the kernel's command line.

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

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

1113	default "8"
1114	---help---
1115	  "Tagged command queuing" is a feature of SCSI-2 which improves
1116	  performance: the host adapter can send several SCSI commands to a
1117	  device's queue even if previous commands haven't finished yet.
1118	  Because the device is intelligent, it can optimize its operations
1119	  (like head positioning) based on its own request queue. Some SCSI
1120	  devices don't implement this properly; if you want to disable this
1121	  feature, enter 0 or 1 here (it doesn't matter which).
1122
1123	  The default value is 8 and should be supported by most hard disks.
1124	  This value can be overridden from the boot command line using the
1125	  'tags' option as follows (example):
1126	  'ncr53c8xx=tags:4/t2t3q16/t0u2q10' will set default queue depth to
1127	  4, set queue depth to 16 for target 2 and target 3 on controller 0
1128	  and set queue depth to 10 for target 0 / lun 2 on controller 1.
1129
1130	  The normal answer therefore is to go with the default 8 and to use
1131	  a boot command line option for devices that need to use a different
1132	  command queue depth.
1133
1134	  There is no safe option other than using good SCSI devices.

1144	  Modern hard disks are able to support 64 tags and even more, but
1145	  do not seem to be faster when more than 32 tags are being used.
1146
1147	  So, the normal answer here is to go with the default value 32 unless
1148	  you are using very large hard disks with large cache (>= 1 MB) that
1149	  are able to take advantage of more than 32 tagged commands.
1150

1155	depends on SCSI_ZALON || SCSI_NCR_Q720

1157	---help---
1158	  The SCSI Parallel Interface-2 Standard defines 5 classes of transfer
1159	  rates: FAST-5, FAST-10, FAST-20, FAST-40 and FAST-80.  The numbers
1160	  are respectively the maximum data transfer rates in mega-transfers
1161	  per second for each class.  For example, a FAST-20 Wide 16 device is
1162	  able to transfer data at 20 million 16 bit packets per second for a
1163	  total rate of 40 MB/s.
1164
1165	  You may specify 0 if you want to only use asynchronous data
1166	  transfers. This is the safest and slowest option. Otherwise, specify
1167	  a value between 5 and 80, depending on the capability of your SCSI
1168	  controller.  The higher the number, the faster the data transfer.
1169	  Note that 80 should normally be ok since the driver decreases the
1170	  value automatically according to the controller's capabilities.
1171
1172	  Your answer to this question is ignored for controllers with NVRAM,
1173	  since the driver will get this information from the user set-up.  It
1174	  also can be overridden using a boot setup option, as follows
1175	  (example): 'ncr53c8xx=sync:12' will allow the driver to negotiate
1176	  for FAST-20 synchronous data transfer (20 mega-transfers per
1177	  second).
1178
1179	  The normal answer therefore is not to go with the default but to
1180	  select the maximum value 80 allowing the driver to use the maximum
1181	  value supported by each controller. If this causes problems with
1182	  your SCSI devices, you should come back and decrease the value.
1183
1184	  There is no safe option other than using good cabling, right
1185	  terminations and SCSI conformant devices.
