Unfortunately, it doesn't seem like everything is working just fine.
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. :)
