Ah, ok. When I did the port to the SC2200 I skirted the whole issue by not setting up a pirq table, instead I just wrote the correct values into the interrupt line registers of each PCI device. I'll try to get the time to look at LinuxBIOS again and set up a RAM mapping for 0xf0000. It's just a few bits in a register that has to be set., /Christer -- "Just how much can I get away with and still go to heaven?"
