Your new motherboard may be treating the hard drive
cylinders/heads/sectors
problem differently than the old motherboard.
There are LBA, Large, and other methods.
Try to set the BIOS handling of IDE C/H/S to the same method the old
motherboard used.
Can you boot from the Linux boot floppy that was
created during the install? If you can, then you have another way
around the problem:
Add a line to the top of /etc/lilo.conf that contains one word:
linear
and run lilo again:
# /sbin/lilo
You may then be able to boot from the hard drive.
If you don't have that floppy, or it doesn't work, you
may be able to boot using the 'rescue' method that
uses one or two diskettes you make with rawrite.exe
from the RedHat CD.
