_________________________________________________________________ STACKER NOTE Stac Electronics Technical Note Subject: QEMM386 OPTIMIZE and STACKER version 1.x. Tech016 - 2/20/92 Page 1 OF 2 _________________________________________________________________ Note: This procedure may be used with Stacker 2.0, however, it is recommended that you use the SSWAP upgrade. See tech030. Introduction: 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. 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 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.
