  This file contains information on using Adaptec SCSI host adapters with
  Central Point Backup v8.

  =============
  What is SCSI?
  =============

  SCSI is rapidly becoming the standard peripheral interface because it
  facilitates the connection of diverse, multiple peripheral devices to one
  host adapter, and it offers high bus bandwidths across the host and drive
  interfaces.  The only truly intelligent I/O interface, SCSI functions
  like a host bus, off-loading tasks normally performed by the CPU, thus
  increasing system performance.  SCSI makes a system more flexible because
  it can be expanded and changed without affecting existing device driver
  software or interface hardware.

  =============
  What is ASPI?
  =============

  ASPI stands for Advanced SCSI Programming Interface.  It is a programming
  interface which provides a means for drivers/utilities to share the same
  SCSI host adapter.  This allows for multiple types of SCSI devices (e.g.
  disk, tape, CD-ROM, WORM, etc.) to be placed on one SCSI host adapter.
  This keeps costs down while freeing up your internal slots.  Developed by
  Adaptec, the ASPI standard has also been adopted by numerous software
  companies and SCSI host adapter manufacturers.

  =========================
  What is ASPI for Windows?
  =========================

  "ASPI for Windows" is a new interface developed by Adaptec.  Previously,
  Windows applications that wanted to talk to ASPI had to allocate all of
  its data buffers down in DOS memory.  It also required a processor switch
  from protected mode to V86/real mode.  Seeking to eliminate these
  limitations, Adaptec has defined the "ASPI for Windows" interface.  This
  interface allows applications to allocate its data buffers wherever 
  it can get them, and call ASPI directly in protected mode, and stay in 
  protected mode.  Seeking to assist existing users of Adaptec's "ASPI for 
  DOS" managers, Adaptec has worked with Central Point Software to make the 
  "ASPI for DOS/Windows" files available with Central Point Backup v8.  
  These files are included with Central Point Backup v8 as a convenience,
  but work only with our Windows version of Central Point Backup.

  =================
  Do you need ASPI?
  =================

  As stated earlier, ASPI allows multiple types of SCSI devices to coexist
  on a single SCSI host adapter.  What if you only have tape drives attached
  to your Adaptec SCSI host adapter?  If this is the case, and if the host
  adapter is directly supported by Central Point Backup v8, using ASPI is
  not required.  Please refer to Central Point Backup's documentation for
  more information.

  ============================
  Supported SCSI Host Adapters
  ============================

  Central Point Backup v8 currently supports the following Adaptec SCSI
  Host Adapters:

  --------------------------------------------------------------------------
  Host Adapter                 Description
  --------------------------------------------------------------------------
  Adaptec AHA-1540/1542        ISA to SCSI Host Adapter (bus-master)
  Adaptec AHA-1520/1522/1510   ISA to SCSI Host Adapter
  Adaptec AIC-6260             ISA to SCSI Host Adapter (for motherboards)
  Adaptec AHA-1740/1742/1744   EISA to SCSI Host Adapter (bus-master)
  Adaptec AHA-1640             Microchannel to SCSI Host Adapter (bus-master)
  --------------------------------------------------------------------------

  NOTE:  A '2' at the end of the model # (for example, AHA-1542) indicates
         that the host adapter also includes an on-board floppy controller
         which can be enabled or disabled (default=enabled).

  NOTE:  Central Point Backup does not directly support the Adaptec 
         AHA-1520/1522/1510 and the Adaptec AIC-6260. You must use the 
         ASPI driver, ASPI2DOS.SYS. 

  ===============
  Adaptec Drivers
  ===============

  To assist in upgrading existing Adaptec ASPI users, Adaptec has made its
  drivers available with Central Point Backup v8.  The following drivers
  are included:

  --------------------------------------------------------------------------
  Driver          Description
  --------------------------------------------------------------------------
  ASPI4DOS.SYS    Adaptec AHA-1540/1542/1640 ASPI for DOS/Windows manager.
  ASPI2DOS.SYS    Adaptec AHA-1520/1522/1510 AIC-6260 ASPI for DOS/Windows
                  manager.
  ASPIEDOS.SYS    Adaptec AHA-1740/1742/1744 (enhanced mode) ASPI for DOS/
                  Windows manager.
  WINASPI.DLL     ASPI for Windows interface.*
  VASPID.386      ASPI for Windows VxD for Windows 386 enhanced mode.*
  --------------------------------------------------------------------------
  * Files provided as a convenience, but not used in DOS.

  NOTE:  If you install Central Point Backup for Windows, VASPID.386 and 
         WINASPI.DLL are automatically copied into your Windows' SYSTEM 
         subdirectory by Central Point Backup's INSTALL utility.  However,
         if you install only the DOS version of Central Point Backup,
         VASPID.386 and WINASPI.DLL are NOT copied to your Windows' SYSTEM
         subdirectory. If you have converted to ASPI and use Windows, you
         can manually copy these two files to your Windows' SYSTEM sub-
         directory.  There is NO need for you to edit any of your .INI files
         (e.g. SYSTEM.INI).  In either case, the .SYS drivers are auto-
         matically copied into CPBACKUP's SYSTEM subdirectory.

  ============
  ASPI4DOS.SYS
  ============

  ASPI4DOS.SYS is Adaptec's AHA-1540/1542/1640 ASPI for DOS/Windows manager.
  Please refer to your existing Adaptec documentation as to how to load this
  driver into your CONFIG.SYS.  A few of the optional command line switches
  are described below:

 
  --------------------------------------------------------------------------
  Switch                Description
  --------------------------------------------------------------------------
  /P<port address>      Sets the port address that the driver uses to
                        communicate with the host adapter.  This value is in
                        hex.  Valid addresses are:

                        130, 134, 230, 234, 330, 334 (e.g. /P230)

                        If this option is not used, the driver will default
                        to port 330.

  /S<slot number>       Sets the slot number where the driver will find your
                        AHA-1640 host adapter.  The valid slot values are:

                        1,2,3,4,5,6,7,8 (e.g. /S3)

                        If this option is not used, the driver will scan the
                        slots starting with slot #1 and attach all of the
                        AHA-1640s that it finds.

  /D                    This option will display useful information about
                        the host adapter and attached SCSI devices during
                        boot.
  --------------------------------------------------------------------------

  Brief list of additional command line switches:

  /L                    Enable support for multiple LUNs.
  /PAUSE                Pause after driver initialization complete.
  /F<bus off time>      Set host adapter bus-off time (AHA-1540/1542 only).
  /N<bus on time>       Set host adapter bus-on time (AHA-1540/1542 only).
  /X<speed>             Set host adapter transfer rate (AHA-1540/1542 only).
  /NORST                Don't hard reset the host adapter during driver load.

  manager.  Please refer to your existing Adaptec documentation as to how to
  load this driver into your CONFIG.SYS.  A few of the optional command line
  switches are described below:

  --------------------------------------------------------------------------
  Switch                Description
  --------------------------------------------------------------------------
  /P<port address>      Sets the port address that the driver uses to
                        communicate with the host adapter.  This value is in
                        hex.  Valid addresses are:

                        140, 340 (e.g. /P140)

                        If this option is not used, the driver will default
                        to port 340.

  /D                    This option will display useful information about

                        boot.

                        AHA-1510 / AIC-6260 specific command line options:

  /Z                    This command line option MUST be used if you have
                        an Adaptec AHA-1510 SCSI host adapter.

  /Q<IRQ channel>       This command line switch must be used if you are not
                        using IRQ 11.  (e.g. device=aspi2dos.sys /z /q10)
  --------------------------------------------------------------------------

  Brief list of additional command line switches:

  /B                    Enable automatic retry on busy
  /B-                   Disable automatic retry on busy
  /L                    Enable support for multiple LUNs.
  /PAUSE                Pause after driver initialization complete.

  NOTE:  Since the Adaptec AHA-1510 SCSI host adapter does not have jumpers
  to set its configuration options, the following additional command line
  line options are allowed.  For the AHA-1520/1522, these equivalent settings
  settings would be set by jumpers on the host adapter.

  /C                    Disable SCSI disconnection
  /C-                   Enable SCSI disconnection
