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

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

223	  This turns on a logging facility that can be used to debug a number
224	  of SCSI related problems.
225
226	  If you say Y here, no logging output will appear by default, but you
227	  can enable logging by saying Y to "/proc file system support" and
228	  "Sysctl support" below and executing the command
229
230	  echo <bitmask> > /proc/sys/dev/scsi/logging_level
231
232	  where <bitmask> is a four byte value representing the logging type
233	  and logging level for each type of logging selected.
234
235	  There are a number of logging types and you can find them in the
236	  source at <file:drivers/scsi/scsi_logging.h>. The logging levels
237	  are also described in that file and they determine the verbosity of
238	  the logging for each logging type.
239
240	  If you say N here, it may be harder to track down some types of SCSI
241	  problems. If you say Y here your kernel will be somewhat larger, but
242	  there should be no noticeable performance impact as long as you have
243	  logging turned off.

253	  You can override this choice by specifying "scsi_mod.scan=sync"

1037	  feature, enter 0 or 1 here (it doesn't matter which).
1038
1039	  The default value is 8 and should be supported by most hard disks.
1040	  This value can be overridden from the boot command line using the
1041	  'tags' option as follows (example):
1042	  'ncr53c8xx=tags:4/t2t3q16/t0u2q10' will set default queue depth to
1043	  4, set queue depth to 16 for target 2 and target 3 on controller 0
1044	  and set queue depth to 10 for target 0 / lun 2 on controller 1.
1045
1046	  The normal answer therefore is to go with the default 8 and to use
1047	  a boot command line option for devices that need to use a different
1048	  command queue depth.
1049
1050	  There is no safe option other than using good SCSI devices.

1056	---help---
1057	  This option allows you to specify the maximum number of commands
1058	  that can be queued to any device, when tagged command queuing is
1059	  possible. The default value is 32. Minimum is 2, maximum is 64.
1060	  Modern hard disks are able to support 64 tags and even more, but
1061	  do not seem to be faster when more than 32 tags are being used.
1062
1063	  So, the normal answer here is to go with the default value 32 unless
1064	  you are using very large hard disks with large cache (>= 1 MB) that
1065	  are able to take advantage of more than 32 tagged commands.
1066

1070	int "synchronous transfers frequency in MHz"
1071	depends on SCSI_ZALON
1072	default "20"
1073	---help---
1074	  The SCSI Parallel Interface-2 Standard defines 5 classes of transfer
1075	  rates: FAST-5, FAST-10, FAST-20, FAST-40 and FAST-80.  The numbers
1076	  are respectively the maximum data transfer rates in mega-transfers
1077	  per second for each class.  For example, a FAST-20 Wide 16 device is
1078	  able to transfer data at 20 million 16 bit packets per second for a
1079	  total rate of 40 MB/s.
1080
1081	  You may specify 0 if you want to only use asynchronous data
1082	  transfers. This is the safest and slowest option. Otherwise, specify
1083	  a value between 5 and 80, depending on the capability of your SCSI
1084	  controller.  The higher the number, the faster the data transfer.
1085	  Note that 80 should normally be ok since the driver decreases the
1086	  value automatically according to the controller's capabilities.
1087
1088	  Your answer to this question is ignored for controllers with NVRAM,
1089	  since the driver will get this information from the user set-up.  It
1090	  also can be overridden using a boot setup option, as follows
1091	  (example): 'ncr53c8xx=sync:12' will allow the driver to negotiate
1092	  for FAST-20 synchronous data transfer (20 mega-transfers per
1093	  second).
1094
1095	  The normal answer therefore is not to go with the default but to
1096	  select the maximum value 80 allowing the driver to use the maximum
1097	  value supported by each controller. If this causes problems with
1098	  your SCSI devices, you should come back and decrease the value.
1099
1100	  There is no safe option other than using good cabling, right
1101	  terminations and SCSI conformant devices.
