Not motherboard type. Motherboard chipset type.
Marcus put it best: "IRQ assignment can't be

this is for a simple reason: operating systems generally can't be hard-coded to
a particular motherboard. And THERE IS NO WAY to automatically detect a
motherboard type. NONE. NADA. CAN'T GO THERE. The BIOS, since it is going to

You CAN detect a motherboard type, by grepping strings out of the BIOS
ROM. But that is not the point here. The motherboard CHIPSET type is
easily detected, generally by a simple PCI vendor/device id match.
WRT IRQ assignment, Marcus is wrong. In a hotplug system, the OS _must_
do the assignment. Even Microsoft knows this. That is why most
modern BIOS ROMs come with interrupt routing tables, which give the OS a
[somewhat] standard method for
This is also why newer motherboards include a Windows' "IRQ driver" or
similar -- so the --OS-- can talk to your motherboard.
