Patch their driver to use your card's I/O address. Start with: cd /etc/conf/pack.d/theirdriver dis Driver.o | egrep -i '278|378|3bc' That may or may not match -- depends whether their code explicitly mentions the possible port addresses, or uses a data structure. If it's a data structure, hexdump the driver and look for those values. Patch, relink, reboot, see what happens. (Save original copies of anything you touch!) >Bela<
