You can't seriously suggest that the operating system should be able to detect
the motherboard type automatically! While in *your* application, you could
hard code the motherboard setups into Linux, this is generally Not A Solution.
Marcus put it best: "IRQ assignment can't be done in the operating system". And
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
be *glued* to the motherboard, is a much more reasonable choice for hard
coding...
