[Qemu-devel] qemu page fault on app running win98 as guest OS

[Phil Rasch]

Hi All,

I have installed qemu on a linux 2.4.21 kernel. I installed the CVS snapshot 
from 2004-6-17. Then I installed Win98 as the guest OS following Hetz Ben 
Hamo's Windows 9X (Guest) with QEMU - How to at 
<http://dad-answers.com/qemu/howto/qemu-win98-howto.html>

Everything worked great so far. I havent had any problems. But all that I have 
done is install the drivers for printer and graphics adaptor, and get the 
network (including network printers and file sharing) working under tun/tap. 
No problems until now.

The whole reason for doing this is that I wanted to run a few win98 apps that 
I have too much invested in to stop now. I wanted to run a label making 
program marketed by wasp labeller. 

When I try to run the binary, after doing the install, the application 
crashes, and  I get the following message:


WLAB32 caused an invalid page fault in
module WLAB32.EXE at 0167:0077528b.

So here are my questions. Is the problem likely to be in QEMU or in the 
application? If it is in the application, since it works when running win98 
in native mode are there any suggested workarounds for applications that fail 
under QEMU?  Am I expecting too much from this version of QEMU? 

Thanks for any advice you might have.
