OK.. then maybe my boards is now on the blacklist :( I think the problem is that
TYAN did not correctly implement the MP table, cause they map all PCI interrupts
to the ISA bus.
You can choose in the BIOS what type of IRQ you want to use for the internal IDE
controller (edge or level, #A, #B ..), but this does not affect the MP table.
I know the tyan bios is a crap...

Thx for fixing correct code to work with buggy bioses...
