It's been a while ago that i've been using a Bt742A. I remember that
it wasn't totally unproblematical for me either.
. turn off ISA DMA emulation,
. use level-triggered IRQ,

...disable the ISA Buslogic driver. Since the EISA device will also
respond on the ISA addresses, the driver gets confused otherwise.

Because it didn't have EISA controller code, so the card has been
handled as some sort of an ``extended ISA'' device. There was
definately no EISA autoprobing in FreeBSD <= 2.1R, but it is there
now.

Never trust an operating system you don't have sources for. ;-)
