Did you modify any files?

Your error code isn't listed.
Did you try a reboot? Did you get the same error? Does the motherboard see the hard drive during the BIOS POST?
Your MBR might of been corrupted, boot partition problem or a hard drive problem.
You can try to reinstall lilo. Boot using the 1st CD and select rescue mode. See any errors during boot?
Should see a menu where you can select to reinstall bootloader.
If that fails then can you mount the partitions (another menu selection)? Any errors?
To remove lilo you can use the XP install cd and boot to its rescue mode and then use the program fixmbr.
