|
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.

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.
