Description of problem:
Xconfigurator dumps core with "illegal instruction" when RH7.0 is booted with
Loadlin 6.1from MSDOS 5.0 running Qemm 8. It works fine when booted with RH7.0
boot disk, or when booted with MSDOS 5 boot disk and Loadlin 6.1 is run from
Version-Release number of selected component (if applicable):
I have Linux installed on its own drive (hdb), and boot to a DOS /Win3.11 drive
The machine is question was upgraded from RH 6.0 to 7.0 and working fine. One
day X Windows wouldn't start (dumped core.) I ran Xconfigurator, and it crashed
also. I tried to run xf86config, but the resulting XF86Config file didn't work
because of "no mouse." I re-installed (Custom Upgrade} all the XFree rpms from
the RH CD. Now Xwindows would start, but Xconfigurator continued to crash. When
trying xf86cfg, I noticed that there was a "ghost image" of my MSDOS screen.
Since my MSDOS drive isn't mounted, I assumed there must be something strange
going on with the video memory.

It appears that either your hardware is faulty, or your installation is
At any rate, we do not support LOADLIN, so if the problem is not reproduceable
without loadlin by using supported booting/installation methods, then it
is outside of the scope of what we support.
Illegal instruction does not indicate a software bug generally, but data
corruption. QEMM could be causing this perhaps.
Thanks for the insights. I'll "play" with Qemm, although Linux is so much fun, I
may never need it again.
