STAC ELECTRONICS TECHNICAL SUPPORT BULLETIN NUMBER: 018 SUBJECT: WINDOW3.0 DATE: September 18, 1991 TIME: SOURCE: Tech Support, Engineering, User's Manual SUPERCEDES/ TECH003 Dated 4/14/1991 SUPERCEDED BY: RELEASE STATUS: Public TITLE: WINDOWS 3.0 in enhanced mode and STACKER OVERVIEW: WINDOWS is a memory-intensive program. It can be run in enhanced mode to take advantage of extended memory, and such operation is compatible with STACKER. ISSUES/COMMENTS: 1) When the XT/8 coprocessor board is present, its address range must be excluded in the WINDOWS SYSTEM.INI file. Overlooking this step can lead to corruption of the Windows directory. Omitting the EMMExclude can also lead to "Insufficient Memory" errors when launching Windows programs. Use of the AT/16 coprocessor presents no such problems. 2) Permanent swap files cannot reside on the STACKER volume; (Windows does not present it as an option). 3) Temporary swap files should also reside on the uncompressed drive. 4) With third party (non-Microsoft) memory managers, certain files must exist in the identical directory paths on both the compressed Stacker drive and in the uncompressed boot drive. 386MAX BLUEMAX QEMM386 ----------- ------------ ------------ 386MAX.SYS BLUEMAX.SYS QEMM386.SYS 386LOAD.SYS 385LOAD.SYS LOADHI.SYS 386MAX.VXD BLUEMAX.VXD WINHIRAM.VXD RECOMMENDED ACTIONS: 1) If WINDOWS is run in enhanced mode AND the XT/8 coprocessor board is installed, add an EMMExclude statement to WINDOWS\SYSTEM.INI under the heading [386ENH] (see User's Manual, "Microsoft Windows 3.0 in 386 Enhanced Mode Users"). This should be done BEFORE WINDOWS is loaded, and can be accomplished using any text editor. (If the coprocessor is disabled, SYSTEM.INI may be modified using NOTEPAD.) 2) If a permanent swap file will be part of the configuration, leave sufficient uncompressed space on the host volume. If there is not enough uncompressed space and you have Stacker version 2.0 or greater, use SDEFRAG to physically shrink the STACVOL file. If you are using version 1.12 or lower,the STACKER volume must be SREMOVEd, and a smaller one created.� 3) Temporary swap files left on the uncompressed drive will not cause fragmentation in the STACKER volume. 4) If the STACKER volume becomes corrupted or write-protected due to an interrupted 386-enhanced session: a) verify that STACKER coprocessor card address has been excluded in SYSTEM.INI; b) run SCHECK/F on the STACKER volume; c) delete the WIN386.SWP (temporary swap) file; d) run SCHECK/F again; e) reboot before writing anything to disk.
