- ID:ST Optimizing with STACKER
- Quarterdeck Technical Note #194
- by Vernon Balbert
-
- Q: Why won't OPTIMIZE.COM work with STACKER?
- A: In addition to this technote, you should read your STACKER manual for
- more information on QEMM and STACKER as well as the README.DOC file in your
- STACKER subdirectory.
- STACKER does work with optimize, but STACKER adds a device driver to
- the end of your CONFIG.SYS called SSWAP.COM. The line typically reads like
- this:
-
- DEVICE=C:\STACKER\SSWAP.COM C: D:
-
- SSWAP.COM is a non-resident program that switches the drive letters.
- In the example above, drive C: becomes drive D: and drive D: becomes drive
- C:. This makes it easy if you installed STACKER on a drive that already
- had programs so you don't have to re-write your batch files and reconfigure
- your software to run from a different drive. See your STACKER manual for
- information on the use of SSWAP.COM.
-
- When running Optimize, this device line needs to be either remarked or
- removed from the CONFIG.SYS. Also, your AUTOEXEC.BAT probably contains
- references to drive C:. All these references need to be changed to drive
- D:. Conversely, all references to drive D: should be changed to drive C:.
- This is necessary since Optimize requires that the CONFIG.SYS and the
- AUTOEXEC.BAT reside on drive C:.
-
- The next step is to create a QEMM sub-directory on the uncompressed
- drive. This is typically drive D: when the SSWAP.COM device driver is
- loaded in your CONFIG.SYS. The following files need to be in the QEMM
- sub-directory in order to run Optimize properly: QEMM386.SYS (or QEMM.SYS
- if you are running QEMM 50/60, or QEMM-386 version 5.0, or QRAM.SYS),
- OPTIMIZE.COM, LOADHI.SYS, LOADHI.COM, LOGOPT.COM, BUFFERS.COM (if you are
- using DOS 2.x or 3.x), RSTRCFG.SYS, MCA.ADL (if you are running on a
- Microchannel machine), and WINHIRAM.VXD if you are planning on running
- Windows 3.0 in enhanced mode.
-
- Once you have done this, you should reboot before running Optimize so
- that the drives are set up correctly. Now you should be able to run
- Optimize normally. After Optimize has run, you should edit your CONFIG.SYS
- and restore the SSWAP.COM line. Also, you should edit your AUTOEXEC.BAT to
- restore the drive specifications to what they were before; e.g. change all
- references to drive D: to drive C: and all references to drive C: to drive
- D:. Reboot again. You are now getting the most out of your conventional
- memory.
