  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. You also need to say Y here if you have a device which speaks
  18. the SCSI protocol. Examples of this include the parallel port
  19. version of the IOMEGA ZIP drive, USB storage devices, Fibre
  20. Channel, FireWire storage and the IDE-SCSI emulation driver.
  21. To compile this driver as a module, choose M here and read

  81. use the /dev/osstX char device nodes (major 206). Via usb-storage
  82. and ide-scsi, you may be able to drive the USB-x0 and DI-x0 drives
  83. as well. Note that there is also a second generation of OnStream
  84. tape drives (ADR-x0) that supports the standard SCSI-2 commands for
  85. tapes (QIC-157) and can be driven by the standard driver st.
  86. For more information, you may have a look at the SCSI-HOWTO
  87. <http://www.tldp.org/docs.html#howto> and

  575. This is a driver for the old NCR 53c80 series of SCSI controllers
  576. on boards using PIO. Most boards such as the Trantor T130 fit this
  577. category, along with a large number of ISA 8bit controllers shipped

  618. If the adapter isn't found during boot (a common problem for models
  619. 56, 57, 76, and 77) you'll need to use the 'ibmmcascsi=<pun>' kernel
  620. option, where <pun> is the id of the SCSI subsystem (usually 7, but
  621. if that doesn't work check your reference diskette). Owners of
  622. model 95 with a LED-matrix-display can in addition activate some
  623. activity info like under OS/2, but more informative, by setting

  633. In the PC-world and in most modern SCSI-BIOS-setups, SCSI-hard disks
  634. are assigned to the drive letters, starting with the lowest SCSI-id
  635. (physical number -- pun) to be drive C:, as seen from DOS and
  636. similar operating systems. When looking into papers describing the
  637. ANSI-SCSI-standard, this assignment of drives appears to be wrong.
  638. The SCSI-standard follows a hardware-hierarchy which says that id 7
  639. has the highest priority and id 0 the lowest. Therefore, the host
  640. adapters are still today everywhere placed as SCSI-id 7 by default.
  641. In the SCSI-standard, the drive letters express the priority of the
  642. disk. C: should be the hard disk, or a partition on it, with the
  643. highest priority. This must therefore be the disk with the highest
  644. SCSI-id (e.g. 6) and not the one with the lowest! IBM-BIOS kept the
  645. original definition of the SCSI-standard as also industrial- and
  646. process-control-machines, like VME-CPUs running under realtime-OSes
  647. (e.g. LynxOS, OS9) do.
  648. If you like to run Linux on your MCA-machine with the same
  649. assignment of hard disks as seen from e.g. DOS or OS/2 on your
  650. machine, which is in addition conformant to the SCSI-standard, you
  651. must say Y here. This is also necessary for MCA-Linux users who want
  652. to keep downward compatibility to older releases of the
  653. IBM-MCA-SCSI-driver (older than driver-release 2.00 and older than
  654. June 1997).
  655. If you like to have the lowest SCSI-id assigned as drive C:, as
  656. modern SCSI-BIOSes do, which does not conform to the standard, but
  657. is widespread and common in the PC-world of today, you must say N

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

  952. 'tags' option as follows (example):
  953. 'ncr53c8xx=tags:4/t2t3q16/t0u2q10' will set default queue depth to
  954. 4, set queue depth to 16 for target 2 and target 3 on controller 0
  955. and set queue depth to 10 for target 0 / lun 2 on controller 1.
  956. The normal answer therefore is to go with the default 8 and to use
  957. a boot command line option for devices that need to use a different
  958. command queue depth.

  965. This option allows you to specify the maximum number of commands
  966. that can be queued to any device, when tagged command queuing is
  967. possible. The default value is 32. Minimum is 2, maximum is 64.
  968. Modern hard disks are able to support 64 tags and even more, but
  969. do not seem to be faster when more than 32 tags are being used.
  970. So, the normal answer here is to go with the default value 32 unless
  971. you are using very large hard disks with large cache (>= 1 MB) that
  972. are able to take advantage of more than 32 tagged commands.
  973. There is no safe option and the default answer is recommended.

  979. The SCSI Parallel Interface-2 Standard defines 5 classes of transfer
  980. rates: FAST-5, FAST-10, FAST-20, FAST-40 and FAST-80. The numbers
  981. are respectively the maximum data transfer rates in mega-transfers
  982. per second for each class. For example, a FAST-20 Wide 16 device is
  983. able to transfer data at 20 million 16 bit packets per second for a
  984. total rate of 40 MB/s.
  985. You may specify 0 if you want to only use asynchronous data
  986. transfers. This is the safest and slowest option. Otherwise, specify
  987. a value between 5 and 80, depending on the capability of your SCSI
  988. controller. The higher the number, the faster the data transfer.
  989. Note that 80 should normally be ok since the driver decreases the
  990. value automatically according to the controller's capabilities.
  991. Your answer to this question is ignored for controllers with NVRAM,
  992. since the driver will get this information from the user set-up. It
  993. also can be overridden using a boot setup option, as follows
  994. (example): 'ncr53c8xx=sync:12' will allow the driver to negotiate
  995. for FAST-20 synchronous data transfer (20 mega-transfers per
  996. second).
  997. The normal answer therefore is not to go with the default but to
  998. select the maximum value 80 allowing the driver to use the maximum
  999. value supported by each controller. If this causes problems with
  1000. your SCSI devices, you should come back and decrease the value.
  1001. There is no safe option other than using good cabling, right

  1374. Note that all of the above SCSI controllers, except for the builtin
  1375. SCSI controller on the Amiga 4000T, reside on the Zorro expansion
  1376. bus, so you also have to enable Zorro bus support if you want to use
