24	  the name of your SCSI host adapter (the card inside your computer

26	  because you will be asked for it.
27
28	  You also need to say Y here if you have a device which speaks
29	  the SCSI protocol.  Examples of this include the parallel port
30	  version of the IOMEGA ZIP drive, USB storage devices, Fibre

159	  CD-ROMs or tapes, say Y here. These won't be supported by the kernel
160	  directly, so you need some additional software which knows how to
161	  talk to these devices using the SCSI protocol:
162
163	  For scanners, look at SANE (<http://www.sane-project.org/>). For CD
164	  writer software look at Cdrtools
165	  (<http://cdrecord.berlios.de/private/cdrecord.html>)
166	  and for burning a "disk at once": CDRDAO
167	  (<http://cdrdao.sourceforge.net/>). Cdparanoia is a high

169	  For other devices, it's possible that you'll have to write the

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

1109	default "8"
1110	---help---
1111	  "Tagged command queuing" is a feature of SCSI-2 which improves
1112	  performance: the host adapter can send several SCSI commands to a
1113	  device's queue even if previous commands haven't finished yet.
1114	  Because the device is intelligent, it can optimize its operations
1115	  (like head positioning) based on its own request queue. Some SCSI
1116	  devices don't implement this properly; if you want to disable this
1117	  feature, enter 0 or 1 here (it doesn't matter which).
1118
1119	  The default value is 8 and should be supported by most hard disks.
1120	  This value can be overridden from the boot command line using the
1121	  'tags' option as follows (example):
1122	  'ncr53c8xx=tags:4/t2t3q16/t0u2q10' will set default queue depth to
1123	  4, set queue depth to 16 for target 2 and target 3 on controller 0
1124	  and set queue depth to 10 for target 0 / lun 2 on controller 1.
1125
1126	  The normal answer therefore is to go with the default 8 and to use
1127	  a boot command line option for devices that need to use a different
1128	  command queue depth.
1129
1130	  There is no safe option other than using good SCSI devices.

1139	  possible. The default value is 32. Minimum is 2, maximum is 64.
1140	  Modern hard disks are able to support 64 tags and even more, but
1141	  do not seem to be faster when more than 32 tags are being used.
1142
1143	  So, the normal answer here is to go with the default value 32 unless
1144	  you are using very large hard disks with large cache (>= 1 MB) that
1145	  are able to take advantage of more than 32 tagged commands.
1146

1153	---help---
1154	  The SCSI Parallel Interface-2 Standard defines 5 classes of transfer
1155	  rates: FAST-5, FAST-10, FAST-20, FAST-40 and FAST-80.  The numbers
1156	  are respectively the maximum data transfer rates in mega-transfers
1157	  per second for each class.  For example, a FAST-20 Wide 16 device is
1158	  able to transfer data at 20 million 16 bit packets per second for a
1159	  total rate of 40 MB/s.
1160
1161	  You may specify 0 if you want to only use asynchronous data
1162	  transfers. This is the safest and slowest option. Otherwise, specify
1163	  a value between 5 and 80, depending on the capability of your SCSI
1164	  controller.  The higher the number, the faster the data transfer.
1165	  Note that 80 should normally be ok since the driver decreases the
1166	  value automatically according to the controller's capabilities.
1167
1168	  Your answer to this question is ignored for controllers with NVRAM,
1169	  since the driver will get this information from the user set-up.  It
1170	  also can be overridden using a boot setup option, as follows
1171	  (example): 'ncr53c8xx=sync:12' will allow the driver to negotiate
1172	  for FAST-20 synchronous data transfer (20 mega-transfers per
1173	  second).
1174
1175	  The normal answer therefore is not to go with the default but to
1176	  select the maximum value 80 allowing the driver to use the maximum
1177	  value supported by each controller. If this causes problems with
1178	  your SCSI devices, you should come back and decrease the value.
1179
