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

	  You also need to say Y here if you have a device which speaks
	  the SCSI protocol.  Examples of this include the parallel port
	  version of the IOMEGA ZIP drive, USB storage devices, Fibre
	  Channel, FireWire storage and the IDE-SCSI emulation driver.

	  To compile this driver as a module, choose M here and read
	  <file:Documentation/scsi/scsi.txt>.
	  The module will be called scsi_mod.

	  However, do not compile this as a module if your root file system
	  (the one containing the directory /) is located on a SCSI device.

	---help---
	  The OnStream SC-x0 SCSI tape drives can not be driven by the
	  standard st driver, but instead need this special osst driver and
	  use the  /dev/osstX char device nodes (major 206).  Via usb-storage
	  and ide-scsi, you may be able to drive the USB-x0 and DI-x0 drives
	  as well.  Note that there is also a second generation of OnStream
	  tape drives (ADR-x0) that supports the standard SCSI-2 commands for
	  tapes (QIC-157) and can be driven by the standard driver st.
	  For more information, you may have a look at the SCSI-HOWTO
	  <http://www.tldp.org/docs.html#howto>  and
	  <file:Documentation/scsi/osst.txt>  in the kernel source.
	  More info on the OnStream driver may be found on
	  <http://linux1.onstream.nl/test/>
	  Please also have a look at the standard st docu, as most of it
	  applies to osst as well.

	  To compile this driver as a module, choose M here and read

	  <http://www.tldp.org/docs.html#howto>. Also make sure to say
	  Y or M to "ISO 9660 CD-ROM file system support" later.

	  To compile this driver as a module, choose M here and read

config CHR_DEV_SG
	tristate "SCSI generic support"
	depends on SCSI
	---help---
	  If you want to use SCSI scanners, synthesizers or CD-writers or just
	  about anything having "SCSI" in its name other than hard disks,
	  CD-ROMs or tapes, say Y here. These won't be supported by the kernel
	  directly, so you need some additional software which knows how to
	  talk to these devices using the SCSI protocol:

	  For scanners, look at SANE (<http://www.mostang.com/sane/>). For CD
	  writer software look at Cdrtools
	  (<http://www.fokus.gmd.de/research/cc/glone/employees/joerg.schilling/private/cdrecord.html>)
	  and for burning a "disk at once": CDRDAO
	  (<http://cdrdao.sourceforge.net/>). Cdparanoia is a high
	  quality digital reader of audio CDs (<http://www.xiph.org/paranoia/>).
	  For other devices, it's possible that you'll have to write the
	  driver software yourself. Please read the file
	  <file:Documentation/scsi/scsi-generic.txt> for more information.

	  To compile this driver as a module, choose M here and read
	  <file:Documentation/scsi/scsi.txt>. The module will be called sg.

	  If unsure, say N.

	depends on SCSI

config SCSI_MULTI_LUN
	bool "Probe all LUNs on each SCSI device"
	depends on SCSI
	help
	  If you have a SCSI device that supports more than one LUN (Logical
	  Unit Number), e.g. a CD jukebox, and only one LUN is detected, you
	  can say Y here to force the SCSI driver to probe for multiple LUNs.
	  A SCSI device with multiple LUNs acts logically like multiple SCSI
	  devices. The vast majority of SCSI devices have only one LUN, and
	  so most people can say N here. The max_luns boot/module parameter 
	  allows to override this setting.

config SCSI_CONSTANTS
	bool "Verbose SCSI error reporting (kernel size +=12K)"
	depends on SCSI
	help
	  The error messages regarding your SCSI hardware will be easier to
	  understand if you say Y here; it will enlarge your kernel by about
	  12 KB. If in doubt, say Y.

config SCSI_LOGGING
	bool "SCSI logging facility"
	depends on SCSI
	---help---
	  This turns on a logging facility that can be used to debug a number
	  of SCSI related problems.

	  If you say Y here, no logging output will appear by default, but you
	  can enable logging by saying Y to "/proc file system support" and
	  "Sysctl support" below and executing the command

	  echo "scsi log token [level]" > /proc/scsi/scsi

	  at boot time after the /proc file system has been mounted.

	  There are a number of things that can be used for 'token' (you can
	  find them in the source: <file:drivers/scsi/scsi.c>), and this
	  allows you to select the types of information you want, and the
	  level allows you to select the level of verbosity.

	  If you say N here, it may be harder to track down some types of SCSI
	  problems. If you say Y here your kernel will be somewhat larger, but
	  there should be no noticeable performance impact as long as you have
	  logging turned off.

	help
	  WARNING This driver is an older aic7xxx driver and is no longer
	  under active development.  Adaptec, Inc. is writing a new driver to
	  take the place of this one, and it is recommended that whenever
	  possible, people should use the new Adaptec written driver instead
	  of this one.  This driver will eventually be phased out entirely.

	  This is support for the various aic7xxx based Adaptec SCSI
	  controllers. These include the 274x EISA cards; 284x VLB cards;
	  2902, 2910, 293x, 294x, 394x, 3985 and several other PCI and
	  motherboard based SCSI controllers from Adaptec. It does not support
	  the AAA-13x RAID controllers from Adaptec, nor will it likely ever
	  support them. It does not support the 2920 cards from Adaptec that
	  use the Future Domain SCSI controller chip. For those cards, you
	  need the "Future Domain 16xx SCSI support" driver.

	  In general, if the controller is based on an Adaptec SCSI controller
	  chip from the aic777x series or the aic78xx series, this driver
	  should work. The only exception is the 7810 which is specifically
	  not supported (that's the RAID controller chip on the AAA-13x
	  cards).

	  Note that the AHA2920 SCSI host adapter is *not* supported by this
	  driver; choose "Future Domain 16xx SCSI support" instead if you have
	  one of those.

	  Information on the configuration options for this controller can be
	  found by checking the help file for each of the available
	  configuration options. You should read

config IBMMCA_SCSI_ORDER_STANDARD
	bool "Standard SCSI-order"

	---help---
	  In the PC-world and in most modern SCSI-BIOS-setups, SCSI-hard disks
	  are assigned to the drive letters, starting with the lowest SCSI-id
	  (physical number -- pun) to be drive C:, as seen from DOS and
	  similar operating systems. When looking into papers describing the
	  ANSI-SCSI-standard, this assignment of drives appears to be wrong.
	  The SCSI-standard follows a hardware-hierarchy which says that id 7
	  has the highest priority and id 0 the lowest. Therefore, the host
	  adapters are still today everywhere placed as SCSI-id 7 by default.
	  In the SCSI-standard, the drive letters express the priority of the
	  disk. C: should be the hard disk, or a partition on it, with the
	  highest priority. This must therefore be the disk with the highest
	  SCSI-id (e.g. 6) and not the one with the lowest! IBM-BIOS kept the
	  original definition of the SCSI-standard as also industrial- and
	  process-control-machines, like VME-CPUs running under realtime-OSes
	  (e.g. LynxOS, OS9) do.

	  If you like to run Linux on your MCA-machine with the same
	  assignment of hard disks as seen from e.g. DOS or OS/2 on your
	  machine, which is in addition conformant to the SCSI-standard, you
	  must say Y here. This is also necessary for MCA-Linux users who want
	  to keep downward compatibility to older releases of the
	  IBM-MCA-SCSI-driver (older than driver-release 2.00 and older than
	  June 1997).

	  If you like to have the lowest SCSI-id assigned as drive C:, as

	  is widespread and common in the PC-world of today, you must say N
	  here. If unsure, say Y.

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

config SCSI_NCR53C8XX_DEFAULT_TAGS
	int "  default tagged command queue depth"
	depends on SCSI_ZALON || SCSI_NCR_Q720
	default "8"
	---help---
	  "Tagged command queuing" is a feature of SCSI-2 which improves
	  performance: the host adapter can send several SCSI commands to a
	  device's queue even if previous commands haven't finished yet.
	  Because the device is intelligent, it can optimize its operations
	  (like head positioning) based on its own request queue. Some SCSI
	  devices don't implement this properly; if you want to disable this
	  feature, enter 0 or 1 here (it doesn't matter which).

	  The default value is 8 and should be supported by most hard disks.
	  This value can be overridden from the boot command line using the
	  'tags' option as follows (example):
	  'ncr53c8xx=tags:4/t2t3q16/t0u2q10' will set default queue depth to
	  4, set queue depth to 16 for target 2 and target 3 on controller 0
	  and set queue depth to 10 for target 0 / lun 2 on controller 1.

	  The normal answer therefore is to go with the default 8 and to use
	  a boot command line option for devices that need to use a different
	  command queue depth.

	  There is no safe option other than using good SCSI devices.

config SCSI_NCR53C8XX_MAX_TAGS
	int "  maximum number of queued commands"

	  This option allows you to specify the maximum number of commands
	  that can be queued to any device, when tagged command queuing is
	  possible. The default value is 32. Minimum is 2, maximum is 64.
	  Modern hard disks are able to support 64 tags and even more, but
	  do not seem to be faster when more than 32 tags are being used.

	  So, the normal answer here is to go with the default value 32 unless
	  you are using very large hard disks with large cache (>= 1 MB) that
	  are able to take advantage of more than 32 tagged commands.

	  There is no safe option and the default answer is recommended.

config SCSI_NCR53C8XX_SYNC
	int "  synchronous transfers frequency in MHz"
	depends on SCSI_ZALON || SCSI_NCR_Q720
	default "20"
	---help---
	  The SCSI Parallel Interface-2 Standard defines 5 classes of transfer
	  rates: FAST-5, FAST-10, FAST-20, FAST-40 and FAST-80.  The numbers
	  are respectively the maximum data transfer rates in mega-transfers
	  per second for each class.  For example, a FAST-20 Wide 16 device is
	  able to transfer data at 20 million 16 bit packets per second for a
	  total rate of 40 MB/s.

	  You may specify 0 if you want to only use asynchronous data
	  transfers. This is the safest and slowest option. Otherwise, specify
	  a value between 5 and 80, depending on the capability of your SCSI
	  controller.  The higher the number, the faster the data transfer.
	  Note that 80 should normally be ok since the driver decreases the
	  value automatically according to the controller's capabilities.

	  Your answer to this question is ignored for controllers with NVRAM,
	  since the driver will get this information from the user set-up.  It
	  also can be overridden using a boot setup option, as follows
	  (example): 'ncr53c8xx=sync:12' will allow the driver to negotiate
	  for FAST-20 synchronous data transfer (20 mega-transfers per
	  second).

	  The normal answer therefore is not to go with the default but to
	  select the maximum value 80 allowing the driver to use the maximum
	  value supported by each controller. If this causes problems with
	  your SCSI devices, you should come back and decrease the value.

	  There is no safe option other than using good cabling, right

config SCSI_U14_34F_TAGGED_QUEUE
	bool "enable tagged command queueing"

config SCSI_U14_34F_LINKED_COMMANDS
	bool "enable elevator sorting"

	  This option enables elevator sorting for all probed SCSI disks and
	  CD-ROMs. It definitely reduces the average seek distance when doing
	  random seeks, but this does not necessarily result in a noticeable
	  performance improvement: your mileage may vary...
	  This is equivalent to the "u14-34f=lc:y" boot option.

config SCSI_U14_34F_MAX_TAGS

	  This specifies how many SCSI commands can be maximally queued for
	  each probed SCSI device. You should reduce the default value of 8
	  only if you have disks with buggy or limited tagged command support.
	  Minimum is 2 and maximum is 14. This value is also the window size
	  used by the elevator sorting option above. The effective value used
	  by the driver for each probed SCSI device is reported at boot time.

config SCSI_DEBUG
	tristate "SCSI debugging host simulator"
	depends on SCSI
	help
	  This is a host adapter simulator that can simulate multiple hosts
	  each with multiple dummy SCSI devices (disks). It defaults to one
	  host adapter with one dummy SCSI disk. Each dummy disk uses kernel
	  RAM as storage (i.e. it is a ramdisk). To save space when multiple
	  dummy disks are simulated, they share the same kernel RAM for 
	  their storage. See <http://www.torque.net/sg/sdebug.html> for more

	  On Power Macintoshes (and clones) where the MESH SCSI bus adaptor
	  drives a bus which is entirely internal to the machine (such as the
	  7500, 7600, 8500, etc.), the MESH is capable of synchronous
	  operation at up to 10 MB/s. On machines where the SCSI bus
	  controlled by the MESH can have external devices connected, it is
	  usually rated at 5 MB/s. 5 is a safe value here unless you know the
	  MESH SCSI bus is internal only; in that case you can say 10. Say 0
	  to disable synchronous operation.
