I have a 486/PCI motherboard (not ASUS) with an NCR53c810 controller on
it. On the motherboard I can shoose with jumpers to have the controller
use either IRQ 9 or IRQ 11. I want to use IRQ 11, but then my CMOS setup
will only allow 9, so it won't work. What I want to know is if there
is an option I can pass to the kernel to force it to use the NCR on
IRQ 11, bypassing the BIOS. Since the MB is jumpered ofr IRQ 11, if I
can somehow force Linux to use 11 it should hopefully work out. I have
tried passing LILO the command line 'ncr53c810=mem,io,irq' with the
appropriate values but that doesn't seem to do anything. Linux still gets
its info from the PCI BIOS. Is there any way around this? I really don't
want to use IRQ 9.
