Introduction
------------

Microsoft offers SMARTDrive version 4.2 as an alternative to
SMARTDrive version 4.1 for those customers who want more conservative
disk caching and are willing to accept slower disk-write performance.
The enclosed PD0805 disk contains SMARTDrive version 4.2 and
SMARTDRV.TXT, which includes installation instructions and parameter
descriptions. You can view SMARTDRV.TXT in MS-DOS Editor.

  NOTE: MS-DOS 6 Upgrade will continue to include SMARTDrive version
  4.1.


New Features
------------

SMARTDrive version 4.2 includes the following new features:

 - A default option to write the contents of the write-cache to disk
   before returning to the MS-DOS command prompt after completing an
   MS-DOS command or exiting an MS-DOS program or MS-DOS-based
   application.

 - An /N switch that disables the default "write write-cache contents
   to disk" option noted above.

 - A new /X switch that disables write-caching for all drives.
