                         MICROSOFT MOUSE DRIVER VERSION 10.0

    PROBLEM:           When attempting to load the Microsoft Mouse
                       driver, version 10.0, onto any AST system, the
                       following error message may appear:

                            Microsoft mouse not found: Try another 9 or 25
                            pin serial port or check for interrupt conflicts.

    Note:              The mouse is still useable in Windows.

    CAUSE:             The Microsoft Mouse driver, version 10.0 can not
                       properly sense an AST extended BIOS for the PS/2
                       mouse port.

    SOLUTION:          Install the Microsoft Mouse driver version 10.0 for
                       MS-DOS on an AST system, add the following line to the
                       [Mouse] section of the MSINPUT.INI file:

                            FailIfNoExtendedBIOS=FALSE

    SYSTEMS AFFECTED:  All AST systems.
