[comp.sys.ibm.pc.misc] PCTools 7 with QEMM: General Protection Violation

wwitt@adara.intel.com (06/29/91)

Hello everybody,

Yesterday I received my copy of PCTools Version 7 in the mail. Of course,
I installed it right away on my 386 to try it out.

Overall it looks pretty slick, but I've encountered a very annoying and 
fatal problem. While running MS-DOS 5 with QEMM 5.11, QEMM informs me of a
General Protection Violation (Exception 13) whenever I try to run Backup
(cpbackup), System Info (si) or File Find (ff) directly from DOS. The
strange thing is that everything seems to work when I load the programs
not directly from DOS, but through PCShell. Furthermore, I can also start
cpbackup, si and ff in a DOS window under Windows 3.0 running in 386
enhanced mode, without receiving any messages from Windows that a DOS
application has misbehaved. So, what's up?

I looked through the manuals and readme file, but couldn't find anything
that might be relevant to my problem. However, I can't claim that I've read
all three inches of the new PCTools documentation.

Has anybody encountered a similar problem? Are cpbackup, si and ff ill
behaved?

Any help would be much appreciated.

Thanks.

Wolf

My suggestion is to get a copy of the two patches on SIMTEL20 and try again;

Directory PD1:<MSDOS.INFO>        
 Filename   Type Length   Date    Description
==============================================
FUNC24.ZIP    B    2412  910521  QEMM 5.10/5.11/5.12 zero length mem region fix
RALLOC.ZIP    B    2942  910329  EMS/XMS fixes for QEMM-386 5.00/5.10/5.11/5.12
