                          XFORMER/286 COMPATIBILITY ISSUES

    AST EPM Product Marketing has considered all aspects of the following
    compatibility issues regarding the Xformer/286 (part number 202204-XXX).
    They have determined that AST will not attempt to establish the cause of the
    incompatibilities.

    These issues are:

        - A conflict exists between the AST Rampage/286 card and an SMC Arcnet
          PC250 card when the two are installed together in the Xformer/286.  The
          system intermittently re-boots when a DOS command is entered from the
          keyboard.  (PR#B33016)

        - The Xformer/286 intermittently loses setup information stored in CMOS.
          (PR#B33020)

        - After a "warm boot" the  and  arrow keys (on an enhanced
          keyboard) perform the function of changing system speed.  This function
          is normally performed by using the - key sequence in
          conjunction with either the  or  keys.  (PR#B33028)
