Besides that one |> can't use two bts in one box? The PCI BusLogic card must be configured as if it was an ISA card. I.e. the corerct IRQ has to be assigned to the card's slot in the PCI BIOS setup, and the card must have been mapped to the default address by its own BIOS init code ... The new code uses the PCI configuration space registers to find the IRQ and port map actually used by the card. This makes it possible to support any number of cards, and since PCI interrupts are level triggered, they can be shared.
