21	  If you want to use a SCSI hard disk, SCSI tape drive, SCSI CD-ROM or

23	  the name of your SCSI host adapter (the card inside your computer
24	  that "speaks" the SCSI protocol, also called SCSI controller),

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

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

215	  This turns on a logging facility that can be used to debug a number
216	  of SCSI related problems.
217
218	  If you say Y here, no logging output will appear by default, but you
219	  can enable logging by saying Y to "/proc file system support" and
220	  "Sysctl support" below and executing the command
221
222	  echo <bitmask> > /proc/sys/dev/scsi/logging_level
223
224	  where <bitmask> is a four byte value representing the logging type
225	  and logging level for each type of logging selected.
226
227	  There are a number of logging types and you can find them in the
228	  source at <file:drivers/scsi/scsi_logging.h>. The logging levels
229	  are also described in that file and they determine the verbosity of
230	  the logging for each logging type.
231
232	  If you say N here, it may be harder to track down some types of SCSI
233	  problems. If you say Y here your kernel will be somewhat larger, but
234	  there should be no noticeable performance impact as long as you have
235	  logging turned off.

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

1154	default "8"
1155	---help---
1156	  "Tagged command queuing" is a feature of SCSI-2 which improves
1157	  performance: the host adapter can send several SCSI commands to a
1158	  device's queue even if previous commands haven't finished yet.
1159	  Because the device is intelligent, it can optimize its operations
1160	  (like head positioning) based on its own request queue. Some SCSI
1161	  devices don't implement this properly; if you want to disable this
1162	  feature, enter 0 or 1 here (it doesn't matter which).
1163
1164	  The default value is 8 and should be supported by most hard disks.
1165	  This value can be overridden from the boot command line using the
1166	  'tags' option as follows (example):
1167	  'ncr53c8xx=tags:4/t2t3q16/t0u2q10' will set default queue depth to
1168	  4, set queue depth to 16 for target 2 and target 3 on controller 0
1169	  and set queue depth to 10 for target 0 / lun 2 on controller 1.
1170
1171	  The normal answer therefore is to go with the default 8 and to use
1172	  a boot command line option for devices that need to use a different
1173	  command queue depth.
1174
1175	  There is no safe option other than using good SCSI devices.

1181	---help---
1182	  This option allows you to specify the maximum number of commands
1183	  that can be queued to any device, when tagged command queuing is
1184	  possible. The default value is 32. Minimum is 2, maximum is 64.
1185	  Modern hard disks are able to support 64 tags and even more, but
1186	  do not seem to be faster when more than 32 tags are being used.
1187
1188	  So, the normal answer here is to go with the default value 32 unless
1189	  you are using very large hard disks with large cache (>= 1 MB) that
1190	  are able to take advantage of more than 32 tagged commands.
1191

1196	depends on SCSI_ZALON || SCSI_NCR_Q720

1198	---help---
1199	  The SCSI Parallel Interface-2 Standard defines 5 classes of transfer
1200	  rates: FAST-5, FAST-10, FAST-20, FAST-40 and FAST-80.  The numbers
1201	  are respectively the maximum data transfer rates in mega-transfers
1202	  per second for each class.  For example, a FAST-20 Wide 16 device is
1203	  able to transfer data at 20 million 16 bit packets per second for a
1204	  total rate of 40 MB/s.
1205
1206	  You may specify 0 if you want to only use asynchronous data
1207	  transfers. This is the safest and slowest option. Otherwise, specify
1208	  a value between 5 and 80, depending on the capability of your SCSI
1209	  controller.  The higher the number, the faster the data transfer.
1210	  Note that 80 should normally be ok since the driver decreases the
1211	  value automatically according to the controller's capabilities.
1212
1213	  Your answer to this question is ignored for controllers with NVRAM,
1214	  since the driver will get this information from the user set-up.  It
1215	  also can be overridden using a boot setup option, as follows
1216	  (example): 'ncr53c8xx=sync:12' will allow the driver to negotiate
1217	  for FAST-20 synchronous data transfer (20 mega-transfers per
1218	  second).
1219
1220	  The normal answer therefore is not to go with the default but to
1221	  select the maximum value 80 allowing the driver to use the maximum
1222	  value supported by each controller. If this causes problems with
1223	  your SCSI devices, you should come back and decrease the value.
1224
1225	  There is no safe option other than using good cabling, right
1226	  terminations and SCSI conformant devices.
