                   AST PREMIUM EXEC AND TOSHIBA EXPRESSWRITER 301

    PROBLEM:       When using a Toshiba ExpressWriter 301 portable printer on the
                   Premium Exec Notebook errors occur when attempting to print
                   through the parallel port (i.e., "write fault error on device
                   LPT1:: when copying files directly to the parallel port).

    AFFECTED
    SYSTEM:        AST Premium Exec Notebook 386/SX-20

    SOLUTION:      This is not an issue that AST can resolve.  Toshiba has
                   provided a software patch (INT17.COM) which may be added to
                   the AUTOEXEC.BAT file to resolve this problem.  Customers
                   experiencing this problem should contact Toshiba's Technical
                   Support for more information.
