Can you disable ISA compatibility in the BIOS? I attempted a different approach that would filter out cards based on the model number and the type of probe, but since the probe uses reseting the card as its primary detection method, it just won't work (at least not with the bt747 I have here to test with). Even attempting the bt_cmd to get the board type for a non-existant board, just hangs up the machine or simply takes too long to be practical (I waited 5 minutes before hitting the reset button. I think that we can document this enough for it to not be a problem especially since the GENERIC kernel only has one bt unit. What we do once we have a configuration manager is another story. Perhps the card has a second I/O register mapped in the PCI configuration space? Stephan is this allowed? Could it be that I should just search through them all and try to find and "ISA" port? >-- >Rich Kuhns rjk@grauel.com >PO Box 6249 >100 Sawmill Road >Lafayette, IN 47903 >(317)477-6000 x319 -- Justin T.
