[comp.os.msdos.apps] Upper Memory Blocks and Caches

cadsi@ccad.uiowa.edu (CADSI) (04/12/91)

Ok, I have tried PC-CACHE, HyperDisk, and SmartDrive.   I place these
in the upper memory block area (I am using QEMM 5.12) and they seem to
work more or less ok, UNTIL I run something like Windows in 386 Enhanced
mode.  I can guarantee a system hang just by running Paintbrush (the
one that comes w/Windows.  Anybody really running (safely) their
cache in the UMB Areas????  BTW, I used the XS parameter for HyperDisk and
loadhi for the other two (loadhi is the QEMM toy).

Hello Tom,

	I am using QEMM 5.11 with hyperdisk and I am also running windows. There
are no problems even when running PC-Tools Compress with hyperdisk installed.
Note: in the documentation it says that you should run hyperdkx.sys with QEMM
5.11 and above. I don't know if there are problems with hyper386.sys or 
hyper286.sys with QEMM. 

	Maybe you should use Manifest and QEMM's analysis procedure to see if
there are any memory conflicts that may have come about when running windows.

	If there are any questions, you can always ask me.(I will try to help
but no guarantee :-).

Regards,

Michael
