In Windows, yes, all the PCI devices get assigned IRQ 9.. maybe that's not the most efficient way, but that does seem to work. In Linux, only 5 of the devices get the IRQ, and the others don't (firewire, one of the USB controllers, one of the CardBus controllers (an internal one, apparently, because the built-in Orinoco card won't load due to an IRQ conflict with IRQ 9). I'd like to figure out how to get these devices working, whether or not they have to use IRQ 9... then I can worry about making it as efficient as possible. :) --=20 Aaron Gaudio prothontar @ tarnation.dyndns.org http://tarnation.dyndns.org/~aaron ---------------- "From fullness, aspect.
