                            AIC7xxx Driver for Linux
                                 April 15, 1996

Introduction
------------------------
The AIC7xxx SCSI driver adds support for Adaptec (http://www.adaptec.com)
SCSI controllers and chipsets. Major portions of the driver and driver
development are shared between both Linux and FreeBSD. Support for the
AIC-7xxx chipsets have been in the default Linux kernel since approximately
linux-1.1.x and fairly stable since linux-1.2.x, and are also in FreeBSD
2.1.0 or later.

  Supported cards/chipsets
  ------------------------
    Adaptec Cards
    -----------------------
    AHA-274x               
    AHA-2842               
    AHA-2940               
    AHA-2940W              
    AHA-2940U              
    AHA-2940UW             
    AHA-2944D              
    AHA-2944WD
    AHA-3940
    AHA-3940W
    AHA-3985
    AHA-3985W

    Motherboard Chipsets
    -----------------------
    AIC-777x   
    AIC-785x
    AIC-787x
    AIC-788x

    Bus Types
    -----------------------
    W - Wide SCSI, SCSI-3, 16bit bus, 68pin connector, will also support
        SCSI-1/SCSI-2 50pin devices, transfer rates up to 20MB/s.
    U - Ultra SCSI, transfer rates up to 40MB/s.
    D - Differential SCSI.
    T - Twin Channel SCSI. Up to 14 SCSI devices.

    AHA-274x - EISA SCSI controller
    AHA-284x - VLB SCSI controller
    AHA-29xx - PCI SCSI controller
    AHA-394x - PCI controllers with two separate SCSI controllers on-board.
    AHA-398x - PCI RAID controllers with three separate SCSI controllers
               on-board.

    NOTE: The AHA-2920 is NOT a AIC-7xxx based controller, and is not
          handled by this driver.

  People
  ------------------------
    Justin T Gibbs  gibbs@freefall.FreeBSD.org     (BSD Driver Author)
    Dan Eischen     deischen@iworks.InterWorks.org (Linux Driver Co-maintainer)
    Dean Gehnert    deang@teleport.com             (Linux FTP/patch maintainer)
    Jess Johnson    jester@frenzy.com              (AIC7xxx FAQ author)

    Special thanks go to John Aycock (aycock@cpsc.ucalgary.ca), the original
    author of the driver. John has since retired from the project. Thanks
    again for all his work!

  Mailing list
  ------------------------
    There is a mailing list available for users who want to track development
    and converse with other users and developers. This list is for both
    FreeBSD and Linux support of the AIC7xxx chipsets.

    To subscribe to the AIC7xxx mailing list send mail to the list server,
    with "subscribe AIC7xxx" in the body (no Subject: required):
        To: majordomo@FreeBSD.ORG
        ---
        subscribe AIC7xxx

    To unsubscribe from the list, send mail to the list server with:
        To: majordomo@FreeBSD.ORG
        ---
        unsubscribe AIC7xxx

    Send regular messages and replies to: AIC7xxx@FreeBSD.ORG
    
  Command line options
  ------------------------
    "aic7xxx=no_reset" -  Eliminate the SCSI reset delay during startup.
        Some SCSI devices need some extra time to reset.

  /proc support
  ------------------------
    The /proc support for the AIC7xxx can be found in the /proc/scsi/aic7xxx/
    directory. That directory contains a file for each SCSI controller in
    the system. Each file presents the current configuration and transfer
    statistics (enabled with #define in aic7xxx.c) for each controller.

    Thanks to Michael Neuffer for for his upper-level SCSI help, and
    Matthew Jacob for statistics support.
