What is the FIFO URL and the status?
Is it some kind payload for LinuxBIOS?

Maybe the problem is with my PCI code.
Please send me the output log with DEBUG_ALL.
You only seem to scan bus 0:
My PCI scan routine starts from bus 0, and recurses when PCI bridges are
found. I think I took this algorithm from pciutils.
However your board has only host bridges on bus 0, so FILO doesn't know
if bus 1 exists.
I checked Etherboot and it just scans bus 0 to 255 unconditionally.
I don't know which is better.
Anyway attached patch changes the PCI scan to Etherboot way.
Thanks. with this patch it also works using PCI.
