12	  If you want to use a SCSI hard disk, SCSI tape drive, SCSI CD-ROM or
13	  any other SCSI device under Linux, say Y and make sure that you know
14	  the name of your SCSI host adapter (the card inside your computer
15	  that "speaks" the SCSI protocol, also called SCSI controller),
16	  because you will be asked for it.
17
18	  You also need to say Y here if you have a device which speaks
19	  the SCSI protocol.  Examples of this include the parallel port
20	  version of the IOMEGA ZIP drive, USB storage devices, Fibre
21	  Channel, FireWire storage and the IDE-SCSI emulation driver.
22
23	  To compile this driver as a module, choose M here and read
24	  <file:Documentation/scsi/scsi.txt>.
25	  The module will be called scsi_mod.
26
27	  However, do not compile this as a module if your root file system
28	  (the one containing the directory /) is located on a SCSI device.

84	  and ide-scsi, you may be able to drive the USB-x0 and DI-x0 drives
85	  as well.  Note that there is also a second generation of OnStream
86	  tape drives (ADR-x0) that supports the standard SCSI-2 commands for
87	  tapes (QIC-157) and can be driven by the standard driver st.
88	  For more information, you may have a look at the SCSI-HOWTO
89	  <http://www.tldp.org/docs.html#howto>  and

126	  about anything having "SCSI" in its name other than hard disks,
127	  CD-ROMs or tapes, say Y here. These won't be supported by the kernel
128	  directly, so you need some additional software which knows how to
129	  talk to these devices using the SCSI protocol:
130
131	  For scanners, look at SANE (<http://www.mostang.com/sane/>). For CD
132	  writer software look at Cdrtools
133	  (<http://www.fokus.gmd.de/research/cc/glone/employees/joerg.schilling/private/cdrecord.html>)
134	  and for burning a "disk at once": CDRDAO
135	  (<http://cdrdao.sourceforge.net/>). Cdparanoia is a high
136	  quality digital reader of audio CDs (<http://www.xiph.org/paranoia/>).
137	  For other devices, it's possible that you'll have to write the
138	  driver software yourself. Please read the file
139	  <file:Documentation/scsi/scsi-generic.txt> for more information.

173	  can say Y here to force the SCSI driver to probe for multiple LUNs.
174	  A SCSI device with multiple LUNs acts logically like multiple SCSI
175	  devices. The vast majority of SCSI devices have only one LUN, and
176	  so most people can say N here. The max_luns boot/module parameter

193
194	  If you say Y here, no logging output will appear by default, but you
195	  can enable logging by saying Y to "/proc file system support" and
196	  "Sysctl support" below and executing the command
197
198	  echo "scsi log token [level]" > /proc/scsi/scsi
199
200	  at boot time after the /proc file system has been mounted.
201
202	  There are a number of things that can be used for 'token' (you can
203	  find them in the source: <file:drivers/scsi/scsi.c>), and this
204	  allows you to select the types of information you want, and the
205	  level allows you to select the level of verbosity.
206
207	  If you say N here, it may be harder to track down some types of SCSI
208	  problems. If you say Y here your kernel will be somewhat larger, but
209	  there should be no noticeable performance impact as long as you have
210	  logging turned off.

821	---help---
822	  In the PC-world and in most modern SCSI-BIOS-setups, SCSI-hard disks
823	  are assigned to the drive letters, starting with the lowest SCSI-id
824	  (physical number -- pun) to be drive C:, as seen from DOS and
825	  similar operating systems. When looking into papers describing the
826	  ANSI-SCSI-standard, this assignment of drives appears to be wrong.
827	  The SCSI-standard follows a hardware-hierarchy which says that id 7
828	  has the highest priority and id 0 the lowest. Therefore, the host
829	  adapters are still today everywhere placed as SCSI-id 7 by default.
830	  In the SCSI-standard, the drive letters express the priority of the
831	  disk. C: should be the hard disk, or a partition on it, with the
832	  highest priority. This must therefore be the disk with the highest
833	  SCSI-id (e.g. 6) and not the one with the lowest! IBM-BIOS kept the
834	  original definition of the SCSI-standard as also industrial- and
835	  process-control-machines, like VME-CPUs running under realtime-OSes
836	  (e.g. LynxOS, OS9) do.
837
838	  If you like to run Linux on your MCA-machine with the same
839	  assignment of hard disks as seen from e.g. DOS or OS/2 on your
840	  machine, which is in addition conformant to the SCSI-standard, you
841	  must say Y here. This is also necessary for MCA-Linux users who want
842	  to keep downward compatibility to older releases of the
843	  IBM-MCA-SCSI-driver (older than driver-release 2.00 and older than
844	  June 1997).
845
846	  If you like to have the lowest SCSI-id assigned as drive C:, as
847	  modern SCSI-BIOSes do, which does not conform to the standard, but
848	  is widespread and common in the PC-world of today, you must say N
849	  here. If unsure, say Y.

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

1148	default "8"
1149	---help---
1150	  "Tagged command queuing" is a feature of SCSI-2 which improves
1151	  performance: the host adapter can send several SCSI commands to a
1152	  device's queue even if previous commands haven't finished yet.
1153	  Because the device is intelligent, it can optimize its operations
1154	  (like head positioning) based on its own request queue. Some SCSI
1155	  devices don't implement this properly; if you want to disable this
1156	  feature, enter 0 or 1 here (it doesn't matter which).
1157
1158	  The default value is 8 and should be supported by most hard disks.
1159	  This value can be overridden from the boot command line using the
1160	  'tags' option as follows (example):
1161	  'ncr53c8xx=tags:4/t2t3q16/t0u2q10' will set default queue depth to
1162	  4, set queue depth to 16 for target 2 and target 3 on controller 0
1163	  and set queue depth to 10 for target 0 / lun 2 on controller 1.
1164
1165	  The normal answer therefore is to go with the default 8 and to use
1166	  a boot command line option for devices that need to use a different
1167	  command queue depth.
1168
1169	  There is no safe option other than using good SCSI devices.

1179	  Modern hard disks are able to support 64 tags and even more, but
1180	  do not seem to be faster when more than 32 tags are being used.
1181
1182	  So, the normal answer here is to go with the default value 32 unless
1183	  you are using very large hard disks with large cache (>= 1 MB) that
1184	  are able to take advantage of more than 32 tagged commands.
1185

1192	---help---
1193	  The SCSI Parallel Interface-2 Standard defines 5 classes of transfer
1194	  rates: FAST-5, FAST-10, FAST-20, FAST-40 and FAST-80.  The numbers
1195	  are respectively the maximum data transfer rates in mega-transfers
1196	  per second for each class.  For example, a FAST-20 Wide 16 device is
1197	  able to transfer data at 20 million 16 bit packets per second for a
1198	  total rate of 40 MB/s.
1199
1200	  You may specify 0 if you want to only use asynchronous data
1201	  transfers. This is the safest and slowest option. Otherwise, specify
1202	  a value between 5 and 80, depending on the capability of your SCSI
1203	  controller.  The higher the number, the faster the data transfer.
1204	  Note that 80 should normally be ok since the driver decreases the
1205	  value automatically according to the controller's capabilities.
1206
1207	  Your answer to this question is ignored for controllers with NVRAM,
1208	  since the driver will get this information from the user set-up.  It
1209	  also can be overridden using a boot setup option, as follows
1210	  (example): 'ncr53c8xx=sync:12' will allow the driver to negotiate
1211	  for FAST-20 synchronous data transfer (20 mega-transfers per
1212	  second).
1213
1214	  The normal answer therefore is not to go with the default but to
1215	  select the maximum value 80 allowing the driver to use the maximum
1216	  value supported by each controller. If this causes problems with
1217	  your SCSI devices, you should come back and decrease the value.
