          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.

          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>)

          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.

          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-changer.txt> for details.

comment "Some SCSI devices (e.g. CD jukebox) support multiple LUNs"
        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.

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.

          If you have built SCSI as modules, enabling this option can
          be a problem as the devices may not have been found by the
          time your system expects them to have been.  You can load the
          scsi_wait_scan module to ensure that all scans have completed.
          If you build your SCSI drivers into the kernel, then everything
          will work fine if you say Y here.

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

        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
          <file:Documentation/scsi/aic7xxx_old.txt> at a minimum before

          <file:Documentation/mca.txt>.

          If the adapter isn't found during boot (a common problem for models
          56, 57, 76, and 77) you'll need to use the 'ibmmcascsi=<pun>' kernel
          option, where <pun> is the id of the SCSI subsystem (usually 7, but
          if that doesn't work check your reference diskette).  Owners of
          model 95 with a LED-matrix-display can in addition activate some
          activity info like under OS/2, but more informative, by setting
          'ibmmcascsi=display' as an additional kernel parameter.  Try "man
          bootparam" or see the documentation of your boot loader about how to

config IBMMCA_SCSI_ORDER_STANDARD
        bool "Standard SCSI-order"
        depends on SCSI_IBMMCA
        ---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
          modern SCSI-BIOSes do, which does not conform to the standard, but
          is widespread and common in the PC-world of today, you must say N
          here. If unsure, say Y.

config IBMMCA_SCSI_DEV_RESET

        ---help---
          By default, SCSI-devices are reset when the machine is powered on.
          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
          reset commands, and can cause your system to hang. So say Y only if
          you know that one of your older devices needs it; N is the safe
          answer.

          Some parallel ports are known to have excessive delays between
          changing the parallel port control register and good data being
          available on the parallel port data/status register. This option
          forces a small delay (1.0 usec to be exact) after changing the
          control register to let things settle out. Enabling this option may
          result in a big drop in performance but some very old parallel ports
          (found in 386 vintage machines) will not work properly.

        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

        ---help---
          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

        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.

          These statistics are not very accurate due to the low frequency
          of the kernel clock (100 Hz on i386) and have performance impact

          This 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.
          This is equivalent to the "u14-34f=tc:y" boot option.

          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 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.

          This is a host adapter simulator that can simulate multiple hosts

          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

          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
