    This file contains information on using Adaptec SCSI host adapters
    with Central Point Backup v9.
  
    =============
    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.
  
    =================
    Do you need ASPI?
    =================
  
    As stated earlier, ASPI allows multiple types of SCSI devices to
    co-exist on a single SCSI host adapter. You do not have to use 
    ASPI if you only have tape drives attached to your Adaptec 
    1540/42, 1640, or 1740/42/44 SCSI host adapter, and if the host 
    adapter is directly supported by Central Point Backup v9.
    
    ============================
    Supported SCSI Host Adapters
    ============================
  
    Central Point Backup v9 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)
    Adaptec AHA-2740/2742        EISA 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 v9. The 
    following drivers are included:
  
    --------------------------------------------------------------------
    Driver          Description
    --------------------------------------------------------------------

                    manager.
    ASPI2DOS.SYS    Adaptec AHA-1520/1522/1510 AIC-6260 ASPI for
                    DOS/Windows manager.
    ASPI7DOS.SYS    Adaptec AHA-2740/2742 ASPI for DOS/Windows manager.

    --------------------------------------------------------------------
   
    ============
    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.
    /CCBS<count>          Number of internal SCSI control blocks.

    ASPI2DOS.SYS is Adaptec's AHA-1520/1522/1510 AIC-6260 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
   --------------------------------------------------------------------

                          140, 340 (e.g. /P140)
  
                          If this option is not used, the driver will
                          default to port 340.

                          about the host adapter and attached SCSI 
                          devices during 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 options are allowed. For the AHA-1520/1522, 
    these equivalent settings would be set by jumpers on 
    the host adapter.
  
    /C                    Disable SCSI disconnection
    /C-                   Enable SCSI disconnection
    /H<scsi id>           Set the SCSI ID of the host adapter
    /U                    Enables synchronous negotiation
    /U-                   Disable synchronous negotiation
    /Y                    Disable SCSI bus parity checking
