15	  If you want to use a SCSI hard disk, SCSI tape drive, SCSI CD-ROM or
16	  any other SCSI device under Linux, say Y and make sure that you know
17	  the name of your SCSI host adapter (the card inside your computer
18	  that "speaks" the SCSI protocol, also called SCSI controller),
19	  because you will be asked for it.
20
21	  You also need to say Y here if you have a device which speaks
22	  the SCSI protocol.  Examples of this include the parallel port
23	  version of the IOMEGA ZIP drive, USB storage devices, Fibre

148	  about anything having "SCSI" in its name other than hard disks,
149	  CD-ROMs or tapes, say Y here. These won't be supported by the kernel
150	  directly, so you need some additional software which knows how to
151	  talk to these devices using the SCSI protocol:
152
153	  For scanners, look at SANE (<http://www.mostang.com/sane/>). For CD
154	  writer software look at Cdrtools
155	  (<http://www.fokus.gmd.de/research/cc/glone/employees/joerg.schilling/private/cdrecord.html>)
156	  and for burning a "disk at once": CDRDAO
157	  (<http://cdrdao.sourceforge.net/>). Cdparanoia is a high
158	  quality digital reader of audio CDs (<http://www.xiph.org/paranoia/>).
159	  For other devices, it's possible that you'll have to write the
160	  driver software yourself. Please read the file

198	  Some devices support more than one LUN (Logical Unit Number) in order
199	  to allow access to several media, e.g. CD jukebox, USB card reader,
200	  mobile phone in mass storage mode. This option forces the kernel to
201	  probe for all LUNs by default. This setting can be overriden by
202	  max_luns boot/module parameter. Note that this option does not affect
203	  devices conforming to SCSI-3 or higher as they can explicitely report
204	  their number of LUNs. It is safe to say Y here unless you have one of
205	  those rare devices which reacts in an unexpected way when probed for
206	  multiple LUNs.

218	depends on SCSI
219	---help---
220	  This turns on a logging facility that can be used to debug a number
221	  of SCSI related problems.
222
223	  If you say Y here, no logging output will appear by default, but you
224	  can enable logging by saying Y to "/proc file system support" and
225	  "Sysctl support" below and executing the command
226
227	  echo <bitmask> > /proc/sys/dev/scsi/logging_level
228
229	  where <bitmask> is a four byte value representing the logging type
230	  and logging level for each type of logging selected.
231
232	  There are a number of logging types and you can find them in the
233	  source at <file:drivers/scsi/scsi_logging.h>. The logging levels
234	  are also described in that file and they determine the verbosity of
235	  the logging for each logging type.
236
237	  If you say N here, it may be harder to track down some types of SCSI
238	  problems. If you say Y here your kernel will be somewhat larger, but
239	  there should be no noticeable performance impact as long as you have
240	  logging turned off.
241
242config SCSI_SCAN_ASYNC
243	bool "Asynchronous SCSI scanning"
244	depends on SCSI
245	help
246	  The SCSI subsystem can probe for devices while the rest of the
247	  system continues booting, and even probe devices on different
248	  busses in parallel, leading to a significant speed-up.
249
250	  If you have built SCSI as modules, enabling this option can
251	  be a problem as the devices may not have been found by the
252	  time your system expects them to have been.  You can load the
253	  scsi_wait_scan module to ensure that all scans have completed.
254	  If you build your SCSI drivers into the kernel, then everything
255	  will work fine if you say Y here.
256
257	  You can override this choice by specifying "scsi_mod.scan=sync"
258	  or async on the kernel's command line.

264	depends on MODULES
265# scsi_wait_scan is a loadable module which waits until all the async scans are
266# complete.  The idea is to use it in initrd/ initramfs scripts.  You modprobe
267# it after all the modprobes of the root SCSI drivers and it will wait until
268# they have all finished scanning their buses before allowing the boot to
269# proceed.  (This method is not applicable if targets boot independently in
270# parallel with the initiator, or with transports with non-deterministic target
271# discovery schemes, or if a transport driver does not support scsi_wait_scan.)
272#
273# This symbol is not exposed as a prompt because little is to be gained by

857	bool "Standard SCSI-order"
858	depends on SCSI_IBMMCA
859	---help---
860	  In the PC-world and in most modern SCSI-BIOS-setups, SCSI-hard disks
861	  are assigned to the drive letters, starting with the lowest SCSI-id
862	  (physical number -- pun) to be drive C:, as seen from DOS and
863	  similar operating systems. When looking into papers describing the
864	  ANSI-SCSI-standard, this assignment of drives appears to be wrong.
865	  The SCSI-standard follows a hardware-hierarchy which says that id 7
866	  has the highest priority and id 0 the lowest. Therefore, the host
867	  adapters are still today everywhere placed as SCSI-id 7 by default.
868	  In the SCSI-standard, the drive letters express the priority of the
869	  disk. C: should be the hard disk, or a partition on it, with the
870	  highest priority. This must therefore be the disk with the highest
871	  SCSI-id (e.g. 6) and not the one with the lowest! IBM-BIOS kept the
872	  original definition of the SCSI-standard as also industrial- and
873	  process-control-machines, like VME-CPUs running under realtime-OSes
874	  (e.g. LynxOS, OS9) do.
875
876	  If you like to run Linux on your MCA-machine with the same
877	  assignment of hard disks as seen from e.g. DOS or OS/2 on your
878	  machine, which is in addition conformant to the SCSI-standard, you
879	  must say Y here. This is also necessary for MCA-Linux users who want
880	  to keep downward compatibility to older releases of the
881	  IBM-MCA-SCSI-driver (older than driver-release 2.00 and older than
882	  June 1997).
883
884	  If you like to have the lowest SCSI-id assigned as drive C:, as
885	  modern SCSI-BIOSes do, which does not conform to the standard, but
886	  is widespread and common in the PC-world of today, you must say N
887	  here. If unsure, say Y.

894	  However, some devices exist, like special-control-devices,
895	  SCSI-CNC-machines, SCSI-printer or scanners of older type, that do
896	  not reset when switched on. If you say Y here, each device connected
897	  to your SCSI-bus will be issued a reset-command after it has been
898	  probed, while the kernel is booting. This may cause problems with
899	  more modern devices, like hard disks, which do not appreciate these
900	  reset commands, and can cause your system to hang. So say Y only if

1250	default "8"
1251	---help---
1252	  "Tagged command queuing" is a feature of SCSI-2 which improves
1253	  performance: the host adapter can send several SCSI commands to a
1254	  device's queue even if previous commands haven't finished yet.
1255	  Because the device is intelligent, it can optimize its operations
1256	  (like head positioning) based on its own request queue. Some SCSI
1257	  devices don't implement this properly; if you want to disable this
1258	  feature, enter 0 or 1 here (it doesn't matter which).
1259
1260	  The default value is 8 and should be supported by most hard disks.
1261	  This value can be overridden from the boot command line using the
1262	  'tags' option as follows (example):
1263	  'ncr53c8xx=tags:4/t2t3q16/t0u2q10' will set default queue depth to
1264	  4, set queue depth to 16 for target 2 and target 3 on controller 0
1265	  and set queue depth to 10 for target 0 / lun 2 on controller 1.
1266
1267	  The normal answer therefore is to go with the default 8 and to use
1268	  a boot command line option for devices that need to use a different
1269	  command queue depth.
1270
1271	  There is no safe option other than using good SCSI devices.

1281	  Modern hard disks are able to support 64 tags and even more, but
1282	  do not seem to be faster when more than 32 tags are being used.
1283
1284	  So, the normal answer here is to go with the default value 32 unless
1285	  you are using very large hard disks with large cache (>= 1 MB) that
1286	  are able to take advantage of more than 32 tagged commands.
1287

1295	  The SCSI Parallel Interface-2 Standard defines 5 classes of transfer
1296	  rates: FAST-5, FAST-10, FAST-20, FAST-40 and FAST-80.  The numbers
1297	  are respectively the maximum data transfer rates in mega-transfers
1298	  per second for each class.  For example, a FAST-20 Wide 16 device is
1299	  able to transfer data at 20 million 16 bit packets per second for a
1300	  total rate of 40 MB/s.
1301
1302	  You may specify 0 if you want to only use asynchronous data
1303	  transfers. This is the safest and slowest option. Otherwise, specify
1304	  a value between 5 and 80, depending on the capability of your SCSI
1305	  controller.  The higher the number, the faster the data transfer.
1306	  Note that 80 should normally be ok since the driver decreases the
1307	  value automatically according to the controller's capabilities.
1308
1309	  Your answer to this question is ignored for controllers with NVRAM,
1310	  since the driver will get this information from the user set-up.  It
1311	  also can be overridden using a boot setup option, as follows
1312	  (example): 'ncr53c8xx=sync:12' will allow the driver to negotiate
1313	  for FAST-20 synchronous data transfer (20 mega-transfers per
1314	  second).
1315
1316	  The normal answer therefore is not to go with the default but to
1317	  select the maximum value 80 allowing the driver to use the maximum
1318	  value supported by each controller. If this causes problems with
1319	  your SCSI devices, you should come back and decrease the value.
