[comp.protocols.nfs] Problems with telnet and DESQview/QEMM386

dcurtis@crc.ac.uk (Dr. David Curtis) (11/22/90)

I have a problem using DESQview with QEMM386 and PC-NFS telnet. PC-NFS
works fine with DESQview and QEMM, and telnet works OK with DESQview,
but if I first load QEMM and then try to run telnet under DESQview I get
a crash, and if I set the window memory protection to 3 I get the
following message as soon as I try to run telnet:

 Protection violation attempted by program at address 650D:64EA.
 The program attempted to write into memory location
 1000:8632, which is outside the program's memory space.
 Select:   Abort     Unprotect     Continue

This is without loading anything high, and I have the window set up
correctly, running in foreground, not being swapped out, not sharing the
processor. I checked with a debugger, and it does seem that telnet is
writing to 1000:8632. I think this must be causing the problems. Isn't
this somewhere in extended memory (converted to expanded by QEMM)? Why
would telnet be doing that? Any solutions?

DESQview is version 2.31. Here is config.sys file:

device=c:\qemm\qemm386 RAM
device=c:\pcip\netdev.sys
shell=c:\dos\command.com c:\dos /e:2000 /p
country=44
buffers=25
FILES=20
DEVICE=C:\NFS\PCNFS_2.SYS  /m /D8
DEVICE=C:\NFS\SOCKDRV.SYS
device=c:\nfs\mpsnfs.sys                                      
LASTDRIVE=m


Thanks for any suggestions
