You can only use getpir if you have a working bios. Otherwise you Will get junk. Considering your board is new, you don't have a Working bios, no? You have to go the hard way and read the Bottom link as to how to make the irq.c file. Base it off of your Motherboard design and make changes where the wires are, based on The shematic.

I am able to load the kernel now. It just executes commands very slowly. One question for the irq_routing table(is that what you mean by irq.c?). The getpir util generates a routing table by looking at the memory config of my "developing" machine. How's it related to my target machine? Any document I can reference? This link mentioned on irq_tables.c http://www.microsoft.com/hwdev/busbios/PCIIRQ.HTM doesn't work. gin
