Ok, there are many things to do.
First I think, we need the PCI controller, the PCI to
ISA bridge and interrupts working.
Is a documentation from the motherboard available ?
I have found some pdfs from the MTX motherboard. But
this seems to be newer hardware.
I have also found a pdf from a ultra 603e/604

Is there a list of devices we must support?
