STACKER NOTE STACKER NOTE
Title: QEMM386 OPTIMIZE and Stacker version 1.x.
STAC FAX Index #2103 - 2/20/92
___________________________________________________________________________
NOTE:
This procedure may be used with Stacker 2.0. However, it is recommended
that you use the SSWAP upgrade. See STACKER NOTE Tec030 (STAX FAX index
#2106) "QEMM Optimize and Stacker 2.0."
Background.
Quarterdeck's QEMM program allows device drivers (for example,STACKER.COM)
and TSR programs to be loaded into upper memory. This package also
includes a utility called OPTIMIZE to organize the loading of drivers into
upper memory. However, OPTIMIZE will not run as expected when the boot
drive is swapped in your Stacker installation.
Setting Up.
1. During this procedure, you will need to temporarily alter two of the
files on your system. These changes may cause other programs to not
run properly. DO NOT try to run any other programs until this
procedure is completed and OPTIMIZE has finished its work.
2. Stacker will work with OPTIMIZE, but the drive swapping feature must
be temporarily disabled. OPTIMIZE expects the CONFIG.SYS and
AUTOEXEC.BAT files to be on the C: drive.
3. On a system where the uncompressed drive (usually drive C:) is not
swapped, OPTIMIZE will work properly when the necessary QEMM files
are on the boot drive.
4. Loading drivers or programs into upper memory requires a block in
upper memory at least as large as the amount of memory required to
initialize the driver or program (this is usually larger than the
resident size of the driver or program).
5. If you use /EMS with Stacker 2.0 and the QEMM 6.0 STEALTH option,
make sure to add DBF=2 to the QEMM device driver line. For example:
Device=c:\qemm\qemm386.sys RAM ST:M DBF=2
Procedure.
1. In the CONFIG.SYS file, locate the line(s) which resemble
DEVICE=C:\STACKER\SSWAP.COM C:\STACVOL.DSK /SYNC Using a text
editor, add "REM " (without the quotes) in front of each of those
lines. For example: REM Device=C:\STACKER\SSWAP.COM .......
2. In the AUTOEXEC.BAT file on the UNCOMPRESSED (boot) drive, exchange
all references between the uncompressed drive and the Stacker volume.
For Example: If the C: and D: drives are swapped, change all
occurrences of C: to D: and from D: to C: in the AUTOEXEC.BAT
on the D: drive.
3. Be sure that the following QEMM programs reside in a QEMM sub-
directory on the UNCOMPRESSED (boot) drive; OPTIMIZE will look for
them there:
QEMM386.SYS (or QEMM.SYS if you are running QEMM 50/60 or QEMM-386
version 5.0)
OPTIMIZE.COM
LOADHI.SYS
LOADHI.COM
LOGOPT.COM (not needed for QEMM ver 6.x)
TESTBIOS.COM
BUFFERS.COM (if you are using a version of DOS 3.x)
RSTRCFG.SYS
MCA.ADL (if you are using a microchannel computer)
WINHIRAM.VXD (if you are planning on running Windows 3.0
in enhanced mode)
WINSTLTH.VXD (if you are planning on running the STEALTH option)
4. Reboot the system to make sure the drives and files are set up
correctly. You may need to continue to edit the AUTOEXEC.BAT file and
reboot until the system boots without error. Typical errors are "File
not found" or "Bad command or filename".
NOTE: At this point, do not try to run any other programs on your system
until the changes to the CONFIG.SYS and AUTOEXEC.BAT files have
been reversed. You will be prompted to do this in Step #6 below.
5. When you get the system booting with no errors, you may change to the
QEMM sub-directory on the uncompressed (boot) drive and run OPTIMIZE.
Refer to the QEMM manual for information on running the OPTIMIZE
program.
6. When OPTIMIZE has completed, restore the AUTOEXEC.BAT file and the
CONFIG.SYS file on the uncompressed drive to their pre-OPTIMIZE status
(ie.. reverse the changes made in Step #1 and Step #2 above).
7. Reboot the system a final time to load the changes to CONFIG.SYS and
AUTOEXEC.BAT into memory.
