	---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, and FireWire storage.

	  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

	  use the  /dev/osstX char device nodes (major 206).  Via usb-storage,
	  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

	  and the CDROM-HOWTO at <http://www.tldp.org/docs.html#howto>.

	  Make sure to say Y or M to "ISO 9660 CD-ROM file system support".

	  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.sane-project.org/>). For CD
	  writer software look at Cdrtools
	  (<http://cdrecord.berlios.de/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.

config CHR_DEV_SCH
	tristate "SCSI media changer support"
	depends on SCSI
	---help---
	  This is a driver for SCSI media changers.  Most common devices are
	  tape libraries and MOD/CDROM jukeboxes.  *Real* jukeboxes, you
	  don't need this for those tiny 6-slot cdrom changers.  Media
	  changers are listed as "Type: Medium Changer" in /proc/scsi/scsi.
	  If you have such hardware and want to use it with linux, say Y
	  here.  Check <file:Documentation/scsi/scsi-changer.txt> for details.
	
	  If you want to compile this as a module ( = code which can be
	  inserted in and removed from the running kernel whenever you want),
	  say M here and read <file:Documentation/kbuild/modules.txt> and
	  <file:Documentation/scsi/scsi.txt>. The module will be called ch.o.
	  If unsure, say N.

config SCSI_ENCLOSURE
	tristate "SCSI Enclosure Support"
	depends on SCSI && ENCLOSURE_SERVICES
	depends on m || SCSI_SAS_ATTRS != m
	help
	  Enclosures are devices sitting on or in SCSI backplanes that
	  manage devices.  If you have a disk cage, the chances are that
	  it has an enclosure device.  Selecting this option will just allow
	  certain enclosure conditions to be reported and is not required.

config SCSI_CONSTANTS
	bool "Verbose SCSI error reporting (kernel size += 36K)"
	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
	  36 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 <bitmask> > /proc/sys/dev/scsi/logging_level

	  where <bitmask> is a four byte value representing the logging type
	  and logging level for each type of logging selected.

	  There are a number of logging types and you can find them in the
	  source at <file:drivers/scsi/scsi_logging.h>. The logging levels
	  are also described in that file and they determine the verbosity of
	  the logging for each logging type.

	  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.

config SCSI_SCAN_ASYNC
	bool "Asynchronous SCSI scanning"
	depends on SCSI
	help
	  The SCSI subsystem can probe for devices while the rest of the
	  system continues booting, and even probe devices on different
	  busses in parallel, leading to a significant speed-up.

	  You can override this choice by specifying "scsi_mod.scan=sync"
	  or async on the kernel's command line.

	  Note that this setting also affects whether resuming from
	  system suspend will be performed asynchronously.

	 The iSCSI Driver provides a host with the ability to access storage
	 through an IP network. The driver uses the iSCSI protocol to transport
	 SCSI requests and responses over a TCP/IP network between the host
	 (the "initiator") and "targets".  Architecturally, the iSCSI driver
	 combines with the host's TCP/IP stack, network drivers, and Network
	 Interface Card (NIC) to provide the same functions as a SCSI or a
	 Fibre Channel (FC) adapter driver with a Host Bus Adapter (HBA).

	 To compile this driver as a module, choose M here: the

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
	  terminations and SCSI conformant devices.

	  feature. In that case, you would say Y here. In general however, to

	  adapter that comes with some HP scanners. This driver requires that
	  the sym53c416 is configured first using some sort of PnP
	  configuration program (e.g. isapnp) or by a PnP aware BIOS. If you
	  are using isapnp then you need to compile this driver as a module
	  and then load it using insmod after isapnp has run. The parameters
	  of the configured card(s) should be passed to the driver. The format
	  is:

	  insmod sym53c416 sym53c416=<base>,<irq> [sym53c416_1=<base>,<irq>]

	  To compile this driver as a module, choose M here: the
	  module will be called sym53c416.

config SCSI_DC395x

	---help---
	  This driver supports PCI SCSI host adapters based on the ASIC
	  TRM-S1040 chip, e.g Tekram DC395(U/UW/F) and DC315(U) variants.

	  This driver works, but is still in experimental status. So better
	  have a bootable disk and a backup in case of emergency.

	  Documentation can be found in <file:Documentation/scsi/dc395x.txt>.

	  To compile this driver as a module, choose M here: the

	---help---
	  This driver supports PCI SCSI host adapters based on the Am53C974A
	  chip, e.g. Tekram DC390(T), DawiControl 2974 and some onboard
	  PCscsi/PCnet (Am53/79C974) solutions.
	  This is a new implementation base on the generic esp_scsi driver.

	  Documentation can be found in <file:Documentation/scsi/tmscsim.txt>.

	  Note that this driver does NOT support Tekram DC390W/U/F, which are
	  based on NCR/Symbios chips. Use "NCR53C8XX SCSI support" for those.

	  To compile this driver as a module, choose M here: the

	help
	  This pseudo driver simulates one or more hosts (SCSI initiators),
	  each with one or more targets, each with one or more logical units.
	  Defaults to one of each, creating a small RAM disk device. Many
	  parameters found in the /sys/bus/pseudo/drivers/scsi_debug
	  directory can be tweaked at run time.
	  See <http://sg.danny.cz/sg/sdebug26.html> for more information.

	  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.

	  On Power Macintoshes (and clones) with two SCSI buses, the external
	  SCSI bus is usually controlled by a 53C94 SCSI bus adaptor. Older
