I/O address 0x7000 sounds quite O.K., because PCI cards are usually
mapped into one of these high regions. IRQ 255 suggests, that the BIOS
did not configure any interrupt for this device. I have never seen a
recent Compaq machine, but IRQ 255 is the same thing that used to be
reported when you plugged a misconfigured NCR53c810 card into a PCI
board. So, I suggest that you try to either adjust your BIOS settings
or play with on-board jumpers (if any). It is quite possible that you
do not notice any problems under other operating systems, because the
drivers might not be using interrupts.
