                           SMARTDRV AND DOS 6.0'S MEMMAKER

    PROBLEM:       When installing MEMMAKER, the error messages "An Invalid State
                   Condition has Ocurred, Press Enter to Undo Changes or "the
                   file MEMMAKER.STS cannot be found, Press a Key to Continue",
                   display on the screen.

    AFFECTED
    SYSTEMS:       ALL Computer Systems Using MS-DOS 6.0

    CAUSE:         SMARTDRV defaults to a "write-back" cache.  When MEMMAKER
                   reboots the computer during its install process, the
                   information read to cache may not have been written to disk,
                   therefore the error messages are displayed.

    SOLUTION:      Use the "write-through" cache option with SMARTDRV.

                   In the AUTOEXEC.BAT file use the following syntax when
                   configuring SMARTDRV:

                   C:\DOS\SMARTDRV.EXE [x] Where x is the letter of the hard
                   drive to cache.

                   C:\DOS\SMARTDRV.EXE C  This would perform a "write-through"
                   cache on C drive.
