STACKER NOTE STACKER NOTE
Title: QEMM386 Optimize and Stacker 2.0
STAC FAX Index #2106 - 3/23/92
___________________________________________________________________________

Background.

If you are a STACKER 2.0 user with an SSWAPped boot drive, you can now
OPTIMIZE with a minimal amount of effort using an upgraded SSWAP.COM.
This file is available on Compuserve, the STAC BBS, and by mail through
STAC technical support.

The upgraded SSWAP handles the many changes OPTIMIZE makes "on the fly."
It works with QEMM 5.XX as well as the latest version of QEMM 6. Just
copy SSWAP.COM to the STACKER directory in the C: drive as well as the
Stacker directory on the SSWAPed host drive. You can determine the
host drive letter by typing: STACKER at the command line. You must
also use the /SYNC parameter on the SSWAP device line in Config.sys.

For example: DEVICE=C:\STACKER\SSWAP.COM C:\STACVOL.DSK /SYNC

Note: QEMM may attempt to load the Stacker device driver into an upper
memory block that is not large enough to accomodate its
initialization size. If this happens, the Stacker driver will
report, "Insufficient high memory, installation aborted." In this
situation, simply edit the Config.sys, remove the references to
QEMM in the Stacker device line, and try to re-optimize. It is
also possible that there is simply not enough upper memory to load
the device into. It may have to be left in "low" memory.

Stacker 2.0, /EMS, and the QEMM 6 STEALTH option.

If Stacker is using EMS and you choose to use QEMM's STEALTH
option, you must include the DBF=2 parameter on the QEMM device line
in Config.sys. For example: DEVICE=C:\QEMM\QEMM386.SYS RAM ST:M DBF=2

Note for QEMM 6.00 and 6.01 users:

If you OPTIMIZE with the SSWAP upgrade and Stacker is using EMS,
you will need to follow the simple procedure below. This is because a
conflict occurs when ANY two or more programs, which OPTIMIZE attempts to
load high, access EMS memory during the OPTIMIZE process.

NOTE: This procedure assumes that SSWAP.COM has already been copied to
both STACKER directories. This procedure is not required for
QEMM 5.x, and 6.02 or later.

Procedure.

1. Create a text file (using SEDIT) called OPTIMIZE.EXC. (NOTE: the
EXC extension stands for "exceptions". This file lists those device
drivers and programs which OPTIMIZE should not attempt to load high.)
This file should be placed in the QEMM subdirectory on both the
uncompressed and compressed drives. In most cases, it's sole contents
should be the following text: SSWAP.COM

However, any other CONFIG.SYS and AUTOEXEC.BAT device drivers and
programs which access EMS memory (except for STACKER.COM) should
also be listed in this file, each on its own line.

2. Run OPTIMIZE.
