The system bios is a bit different for every motherboard type. There are
lots of subtle differences between these motherboards and each one
requires tweaks. 

Example: the c440gx and l440gx+ motherboards are incredibly similar (check
them out on intel.com). They have different BIOSes. 


Thanks for the ROM base address info. This could be useful.
