  21           If you want to use a SCSI hard disk, SCSI tape drive, SCSI CD-ROM or
  22           any other SCSI device under Linux, say Y and make sure that you know
  23           the name of your SCSI host adapter (the card inside your computer
  24           that "speaks" the SCSI protocol, also called SCSI controller),
  25           because you will be asked for it.
  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

 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

 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

 184           changers are listed as "Type: Medium Changer" in /proc/scsi/scsi.

 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

 243           busses in parallel, leading to a significant speed-up.
 244
 245           If you have built SCSI as modules, enabling this option can
 246           be a problem as the devices may not have been found by the
 247           time your system expects them to have been.  You can load the
 248           scsi_wait_scan module to ensure that all scans have completed.
 249           If you build your SCSI drivers into the kernel, then everything
 250           will work fine if you say Y here.
 251
 252           You can override this choice by specifying "scsi_mod.scan=sync"
 253           or async on the kernel's command line.

 791           for free with SCSI scanners. If you have a PAS16, T128 or DMX3191

1161         default "8"
1162         ---help---
1163           "Tagged command queuing" is a feature of SCSI-2 which improves
1164           performance: the host adapter can send several SCSI commands to a
1165           device's queue even if previous commands haven't finished yet.
1166           Because the device is intelligent, it can optimize its operations
1167           (like head positioning) based on its own request queue. Some SCSI
1168           devices don't implement this properly; if you want to disable this
1169           feature, enter 0 or 1 here (it doesn't matter which).
1170
1171           The default value is 8 and should be supported by most hard disks.
1172           This value can be overridden from the boot command line using the
1173           'tags' option as follows (example):
1174           'ncr53c8xx=tags:4/t2t3q16/t0u2q10' will set default queue depth to
1175           4, set queue depth to 16 for target 2 and target 3 on controller 0
1176           and set queue depth to 10 for target 0 / lun 2 on controller 1.
1177
1178           The normal answer therefore is to go with the default 8 and to use
1179           a boot command line option for devices that need to use a different
1180           command queue depth.
1181
1182           There is no safe option other than using good SCSI devices.

1187         default "32"
1188         ---help---
1189           This option allows you to specify the maximum number of commands
1190           that can be queued to any device, when tagged command queuing is
1191           possible. The default value is 32. Minimum is 2, maximum is 64.
1192           Modern hard disks are able to support 64 tags and even more, but
1193           do not seem to be faster when more than 32 tags are being used.
1194
1195           So, the normal answer here is to go with the default value 32 unless
1196           you are using very large hard disks with large cache (>= 1 MB) that
1197           are able to take advantage of more than 32 tagged commands.
1198
1199           There is no safe option and the default answer is recommended.

1205         ---help---
1206           The SCSI Parallel Interface-2 Standard defines 5 classes of transfer
1207           rates: FAST-5, FAST-10, FAST-20, FAST-40 and FAST-80.  The numbers
1208           are respectively the maximum data transfer rates in mega-transfers
1209           per second for each class.  For example, a FAST-20 Wide 16 device is
1210           able to transfer data at 20 million 16 bit packets per second for a
1211           total rate of 40 MB/s.
1212
1213           You may specify 0 if you want to only use asynchronous data
1214           transfers. This is the safest and slowest option. Otherwise, specify
1215           a value between 5 and 80, depending on the capability of your SCSI
1216           controller.  The higher the number, the faster the data transfer.
1217           Note that 80 should normally be ok since the driver decreases the
1218           value automatically according to the controller's capabilities.
1219
1220           Your answer to this question is ignored for controllers with NVRAM,
1221           since the driver will get this information from the user set-up.  It
1222           also can be overridden using a boot setup option, as follows
1223           (example): 'ncr53c8xx=sync:12' will allow the driver to negotiate
1224           for FAST-20 synchronous data transfer (20 mega-transfers per
1225           second).
1226
1227           The normal answer therefore is not to go with the default but to
1228           select the maximum value 80 allowing the driver to use the maximum
1229           value supported by each controller. If this causes problems with
1230           your SCSI devices, you should come back and decrease the value.
1231
1232           There is no safe option other than using good cabling, right
1233           terminations and SCSI conformant devices.

1242           not allow targets to disconnect is not reasonable if there is more
1243           than 1 device on a SCSI bus. The normal answer therefore is N.
