                           AST SYSTEMS WITH IBM'S OS/2 EE

    PROBLEM:       When installing IBM's OS/2 Extended Edition 1.30.1 on an AST
                   system, the following error will occur:

                       "Invalid Configuration"
                       [50.09] diskette drives or types mismatch error.  Run
                       setup...  Press F1 key to continue or Ctrl-Alt-Esc for
                       setup.

                   The above error indicates that the system configuration is
                   lost and setup must be performed for the system to boot
                   properly.

    SYSTEMS
    AFFECTED:      All AST systems

    SOLUTION:      This is not an issue that AST can resolve.  The problem has
                   been corrected by IBM.  Customers experiencing this problem
                   should contact IBM at (800) 237-5511 and ask for either CSD
                   5016 or APAR JR04280.  To insure proper installation of the
                   CSD or APAR, customers should follow the process outlined by
                   the IBM readme files.
