Do I have to have a that big IRQ routing table or is there a simpler LinuxBIOS way? If not since I don't have a table to begin with I'll have to hand generate one.
If you know what values to set on the irq pin for each PCI device for your board, just hard-wire them in hardwaremain, and set the router settings too. You only need the IRQ table if you want linux to do all the routing work.
The microsoft documentation claims that the IRQ routing table is for legacy systems that cannot do dynamic IRQ routing and that ACPI systems should use the ACPI based method.
ah, what do they know anyway :-)
I saw that comment on ACPI but fact is, our newest mobos still have that IRQ table in there.
