It only confuses things. >Watching the messages, the first sign of trouble is: "BT: UNIT NUMBER = >(1) TOO HIGH". Actually, that warning is benign. The real cause of problems is that you have the ISA compatibility port enabled on your Buslogic and FreeBSD is attaching to the PCI port address that the card also exports. I don't know why you can see the upper address but it doesn't work with these cards, but that must be what's happening. Perhaps another probe that touched the same lower I/O address makes the card think that we're going to use the low address and it turns off the PCI address. Anyway, you can fix it by going into the Buslogic BIOS setup and disabling the ISA compatibility port address. Justin T.
