 207	  probe for all LUNs by default. This setting can be overriden by

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

 256	  If you have built SCSI as modules, enabling this option can
 257	  be a problem as the devices may not have been found by the

 259	  scsi_wait_scan module to ensure that all scans have completed.
 260	  If you build your SCSI drivers into the kernel, then everything

 522	  WARNING This driver is an older aic7xxx driver and is no longer
 523	  under active development.  Adaptec, Inc. is writing a new driver to
 524	  take the place of this one, and it is recommended that whenever
 525	  possible, people should use the new Adaptec written driver instead
 526	  of this one.  This driver will eventually be phased out entirely.
 527
 528	  This is support for the various aic7xxx based Adaptec SCSI
 529	  controllers. These include the 274x EISA cards; 284x VLB cards;
 530	  2902, 2910, 293x, 294x, 394x, 3985 and several other PCI and
 531	  motherboard based SCSI controllers from Adaptec. It does not support
 532	  the AAA-13x RAID controllers from Adaptec, nor will it likely ever
 533	  support them. It does not support the 2920 cards from Adaptec that
 534	  use the Future Domain SCSI controller chip. For those cards, you
 535	  need the "Future Domain 16xx SCSI support" driver.
 536
 537	  In general, if the controller is based on an Adaptec SCSI controller
 538	  chip from the aic777x series or the aic78xx series, this driver
 539	  should work. The only exception is the 7810 which is specifically
 540	  not supported (that's the RAID controller chip on the AAA-13x
 541	  cards).
 542
 543	  Note that the AHA2920 SCSI host adapter is *not* supported by this
 544	  driver; choose "Future Domain 16xx SCSI support" instead if you have
 545	  one of those.
 546
 547	  Information on the configuration options for this controller can be
 548	  found by checking the help file for each of the available

 918	---help---
 919	  In the PC-world and in most modern SCSI-BIOS-setups, SCSI-hard disks
 920	  are assigned to the drive letters, starting with the lowest SCSI-id
 921	  (physical number -- pun) to be drive C:, as seen from DOS and
 922	  similar operating systems. When looking into papers describing the
 923	  ANSI-SCSI-standard, this assignment of drives appears to be wrong.
 924	  The SCSI-standard follows a hardware-hierarchy which says that id 7
 925	  has the highest priority and id 0 the lowest. Therefore, the host
 926	  adapters are still today everywhere placed as SCSI-id 7 by default.
 927	  In the SCSI-standard, the drive letters express the priority of the
 928	  disk. C: should be the hard disk, or a partition on it, with the
 929	  highest priority. This must therefore be the disk with the highest
 930	  SCSI-id (e.g. 6) and not the one with the lowest! IBM-BIOS kept the
 931	  original definition of the SCSI-standard as also industrial- and
 932	  process-control-machines, like VME-CPUs running under realtime-OSes
 933	  (e.g. LynxOS, OS9) do.
 934
 935	  If you like to run Linux on your MCA-machine with the same
 936	  assignment of hard disks as seen from e.g. DOS or OS/2 on your
 937	  machine, which is in addition conformant to the SCSI-standard, you
 938	  must say Y here. This is also necessary for MCA-Linux users who want
 939	  to keep downward compatibility to older releases of the
 940	  IBM-MCA-SCSI-driver (older than driver-release 2.00 and older than
 941	  June 1997).
 942
 943	  If you like to have the lowest SCSI-id assigned as drive C:, as
 944	  modern SCSI-BIOSes do, which does not conform to the standard, but
 945	  is widespread and common in the PC-world of today, you must say N

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

1310	default "8"
1311	---help---
1312	  "Tagged command queuing" is a feature of SCSI-2 which improves
1313	  performance: the host adapter can send several SCSI commands to a
1314	  device's queue even if previous commands haven't finished yet.
1315	  Because the device is intelligent, it can optimize its operations
1316	  (like head positioning) based on its own request queue. Some SCSI
1317	  devices don't implement this properly; if you want to disable this
1318	  feature, enter 0 or 1 here (it doesn't matter which).
1319
1320	  The default value is 8 and should be supported by most hard disks.
1321	  This value can be overridden from the boot command line using the
1322	  'tags' option as follows (example):
1323	  'ncr53c8xx=tags:4/t2t3q16/t0u2q10' will set default queue depth to
1324	  4, set queue depth to 16 for target 2 and target 3 on controller 0
1325	  and set queue depth to 10 for target 0 / lun 2 on controller 1.
1326
1327	  The normal answer therefore is to go with the default 8 and to use
1328	  a boot command line option for devices that need to use a different
1329	  command queue depth.
1330
1331	  There is no safe option other than using good SCSI devices.

1341	  Modern hard disks are able to support 64 tags and even more, but
1342	  do not seem to be faster when more than 32 tags are being used.
1343
1344	  So, the normal answer here is to go with the default value 32 unless
1345	  you are using very large hard disks with large cache (>= 1 MB) that
1346	  are able to take advantage of more than 32 tagged commands.
1347

1355	  The SCSI Parallel Interface-2 Standard defines 5 classes of transfer
1356	  rates: FAST-5, FAST-10, FAST-20, FAST-40 and FAST-80.  The numbers
1357	  are respectively the maximum data transfer rates in mega-transfers
1358	  per second for each class.  For example, a FAST-20 Wide 16 device is
1359	  able to transfer data at 20 million 16 bit packets per second for a
1360	  total rate of 40 MB/s.
1361
1362	  You may specify 0 if you want to only use asynchronous data
1363	  transfers. This is the safest and slowest option. Otherwise, specify
1364	  a value between 5 and 80, depending on the capability of your SCSI
1365	  controller.  The higher the number, the faster the data transfer.
1366	  Note that 80 should normally be ok since the driver decreases the
1367	  value automatically according to the controller's capabilities.
1368
1369	  Your answer to this question is ignored for controllers with NVRAM,
1370	  since the driver will get this information from the user set-up.  It
1371	  also can be overridden using a boot setup option, as follows
1372	  (example): 'ncr53c8xx=sync:12' will allow the driver to negotiate
1373	  for FAST-20 synchronous data transfer (20 mega-transfers per
1374	  second).
1375
1376	  The normal answer therefore is not to go with the default but to
1377	  select the maximum value 80 allowing the driver to use the maximum
1378	  value supported by each controller. If this causes problems with
1379	  your SCSI devices, you should come back and decrease the value.
