I wish to thank you for such a thourough investigation. Such problems
have been reported to me quite often, but I've never had the time to check
them out to such a depth.
Thanks again.

Hi,
I think this mail may be usefull to some of you, so lets go...
2 weeks ago I bought an i845 based system, installed Win98 and Slackware
8.1 that I upgraded with XFree86 4.2.99.3. The first days X was running
wonderfully :)
Then I inserted a new PCI card, changed a few settings in the BIOS, upgraded
the default Slackware kernel to 2.4.20, but XFree86 didn't want to run
anymore with the following error :

In fact even with the default Slackware kernel, X didn't want to run... so I
tried to undo all my changes since last successfull run, but couldn't make X
run again. I even tried to install cvs version but unsuccessfully.
I searched the Internet and found some hints such as adding 'Option NoInt10'
or 'Option NoDDC', or changing 'Driver i810' by 'Driver vesa', but
none was working.
After a few hours I found this link :
=== http://xfree86.desiato.de/xfree86/pipermail/xpert/2001-February/005982.html ===
[Xpert]Fix for the Rage 128 ... unknown reason for exception bug
BootGUI=0 in msdos.sys fixes the problem for me ...
=== === ===
So I realized that when X was working, I was launching Linux from the
bootdisk build by the Slackware install; while I was only using loadlin in
Win98's autoexec.bat since my kernel upgrade.
So I tried to have 'BootGUI=0' in msdos.sys but X didn't run.
I checked the difference between my use of loadlin and the one in the
previous URL. I realized that I was using loadlin from autoexec.bat while it
was used from config.sys' shell command in the previous URL.
I changed my config.sys/autoexec.bat as following and now X is running if I
use the lnx2421 menuitem and not if I use casse :
=== config.sys ===
[menu]
menuitem=win98,Windows 98
menuitem=lnx2421,SlackWare 8.1 2.4.21-pre3
menuitem=casse,SlackWare 8.1 2.4.21-pre3 via autoexec.bat

Attached are the XFree86.0.log with menuitems casse and lnx2421 and the
XF86Config used.
Hope it will help some people...
I want to thank all the developers for their great work.
Denis.
