23	  If you want to use a SCSI hard disk, SCSI tape drive, SCSI CD-ROM or
24	  any other SCSI device under Linux, say Y and make sure that you know
25	  the name of your SCSI host adapter (the card inside your computer
26	  that "speaks" the SCSI protocol, also called SCSI controller),
27	  because you will be asked for it.
28
29	  You also need to say Y here if you have a device which speaks
30	  the SCSI protocol.  Examples of this include the parallel port
31	  version of the IOMEGA ZIP drive, USB storage devices, Fibre
32	  Channel, and FireWire storage.

158	  If you want to use SCSI scanners, synthesizers or CD-writers or just
159	  about anything having "SCSI" in its name other than hard disks,
160	  CD-ROMs or tapes, say Y here. These won't be supported by the kernel
161	  directly, so you need some additional software which knows how to
162	  talk to these devices using the SCSI protocol:
163
164	  For scanners, look at SANE (<http://www.sane-project.org/>). For CD
165	  writer software look at Cdrtools
166	  (<http://cdrecord.berlios.de/private/cdrecord.html>)
167	  and for burning a "disk at once": CDRDAO
168	  (<http://cdrdao.sourceforge.net/>). Cdparanoia is a high
169	  quality digital reader of audio CDs (<http://www.xiph.org/paranoia/>).
170	  For other devices, it's possible that you'll have to write the
171	  driver software yourself. Please read the file

218	  This turns on a logging facility that can be used to debug a number
219	  of SCSI related problems.
220
221	  If you say Y here, no logging output will appear by default, but you
222	  can enable logging by saying Y to "/proc file system support" and
223	  "Sysctl support" below and executing the command
224
225	  echo <bitmask> > /proc/sys/dev/scsi/logging_level
226
227	  where <bitmask> is a four byte value representing the logging type
228	  and logging level for each type of logging selected.
229
230	  There are a number of logging types and you can find them in the
231	  source at <file:drivers/scsi/scsi_logging.h>. The logging levels
232	  are also described in that file and they determine the verbosity of
233	  the logging for each logging type.
234
235	  If you say N here, it may be harder to track down some types of SCSI
236	  problems. If you say Y here your kernel will be somewhat larger, but
237	  there should be no noticeable performance impact as long as you have
238	  logging turned off.

248	  You can override this choice by specifying "scsi_mod.scan=sync"
249	  or async on the kernel's command line.

1110	default "8"
1111	---help---
1112	  "Tagged command queuing" is a feature of SCSI-2 which improves
1113	  performance: the host adapter can send several SCSI commands to a
1114	  device's queue even if previous commands haven't finished yet.
1115	  Because the device is intelligent, it can optimize its operations
1116	  (like head positioning) based on its own request queue. Some SCSI
1117	  devices don't implement this properly; if you want to disable this
1118	  feature, enter 0 or 1 here (it doesn't matter which).
1119
1120	  The default value is 8 and should be supported by most hard disks.
1121	  This value can be overridden from the boot command line using the
1122	  'tags' option as follows (example):
1123	  'ncr53c8xx=tags:4/t2t3q16/t0u2q10' will set default queue depth to
1124	  4, set queue depth to 16 for target 2 and target 3 on controller 0
1125	  and set queue depth to 10 for target 0 / lun 2 on controller 1.
1126
1127	  The normal answer therefore is to go with the default 8 and to use
1128	  a boot command line option for devices that need to use a different
1129	  command queue depth.
1130
1131	  There is no safe option other than using good SCSI devices.

1140	  possible. The default value is 32. Minimum is 2, maximum is 64.
1141	  Modern hard disks are able to support 64 tags and even more, but
1142	  do not seem to be faster when more than 32 tags are being used.
1143
1144	  So, the normal answer here is to go with the default value 32 unless
1145	  you are using very large hard disks with large cache (>= 1 MB) that
1146	  are able to take advantage of more than 32 tagged commands.
1147

1154	---help---
1155	  The SCSI Parallel Interface-2 Standard defines 5 classes of transfer
1156	  rates: FAST-5, FAST-10, FAST-20, FAST-40 and FAST-80.  The numbers
1157	  are respectively the maximum data transfer rates in mega-transfers
1158	  per second for each class.  For example, a FAST-20 Wide 16 device is
1159	  able to transfer data at 20 million 16 bit packets per second for a
1160	  total rate of 40 MB/s.
1161
1162	  You may specify 0 if you want to only use asynchronous data
1163	  transfers. This is the safest and slowest option. Otherwise, specify
1164	  a value between 5 and 80, depending on the capability of your SCSI
1165	  controller.  The higher the number, the faster the data transfer.
1166	  Note that 80 should normally be ok since the driver decreases the
1167	  value automatically according to the controller's capabilities.
1168
1169	  Your answer to this question is ignored for controllers with NVRAM,
1170	  since the driver will get this information from the user set-up.  It
1171	  also can be overridden using a boot setup option, as follows
1172	  (example): 'ncr53c8xx=sync:12' will allow the driver to negotiate
1173	  for FAST-20 synchronous data transfer (20 mega-transfers per
1174	  second).
1175
1176	  The normal answer therefore is not to go with the default but to
1177	  select the maximum value 80 allowing the driver to use the maximum
1178	  value supported by each controller. If this causes problems with
1179	  your SCSI devices, you should come back and decrease the value.
