Um, any chance of posting the XF86Config file? That would let us see what has happened.
You may need to copy it to a floppy to post it here, so if you're a newbie here's a step-by-step.
When the box starts up, type linux 3 into the lilo prompt.
Login as root
insert a dos formatted floppy
type
Code:
mount /mnt/floppy
cp /etc/X11/XF86Config-4 /mnt/floppy/
Take the floppy to whatever machine you use for techimo and post the contents of the file in a code tag.
If you're not a newbie and are competent in posting the contents of the file yourself - I apologise. It just saves people asking "How do I do that?" and then having to wait for a reply.
