Using Stacker
-------------
If you are using Stacker to compress your hard disk, there are
certain steps you need to take before setting up Windows.

*  If you want to use a swap file with Windows, you must
   set up the swap file on the uncompressed drive. When
   setting up Stacker, you can leave at least 1 megabyte (MB)
   of disk space uncompressed for storing system files. To
   leave enough space for the swap file, it is recommended
   that the amount of uncompressed disk space equal at least
   twice the amount of system memory. For example, if your
   system has 4 MB of memory, you should leave at least 8 MB
   of disk space uncompressed.

   If Stacker is already set up on your system and there is not
   enough uncompressed disk space for a swap file, you can run
   the STAC utility provided with Stacker to increase the amount
   of uncompressed disk space. For more information, see your
   Stacker documentation.

*  If you are using Stacker version 2.0 or later, Windows Setup
   modifies your CONFIG.SYS and AUTOEXEC.BAT files. When Setup
   is finished making the modifications, it displays a message
   at the end of the Windows portion of Setup notifying you of
   the modifications. If you have used Stacker to swap your
   startup drive, when you restart your system Stacker will
   ask whether you want to update to the new version of the
   CONFIG.SYS or AUTOEXEC.BAT file. It is recommended that you
   update.

   If you are using a version of Stacker earlier than 2.0, you
   may need to modify your CONFIG.SYS and AUTOEXEC.BAT files
   yourself. For more information, see "Modifying Your CONFIG.SYS
   and AUTOEXEC.BAT Files Yourself," following this topic.

*  For best performance, do not use SMARTDrive to cache the
   compressed drive. You only need to cache the uncompressed
   drive. You can include options on the SMARTDRV.EXE line of
   the CONFIG.SYS file to specify which drives to cache.

   For example, if the Stacker swap utility swaps drives C and
   D so that C is compressed and D is uncompressed, you would
   include the following line in your CONFIG.SYS file:

        device=\windows\smartdrv.exe C- D+

For more information about swap files and using SMARTDrive, see
Chapter 14, "Optimizing Windows," in the "Microsoft Windows User's
Guide."
