                       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.
