Yes and no: these cards are dual-personality, and they have been used in their ISA personality only in the beginning. > I tried disabling the bt driver, this did make the above error > message about bt unit number 1 too high go away, and the kernel did > boot properly. Ok. So the basic problem of your PR is solved then? > This is probably something that should go into the install FAQ, is > the same problem present with the Adaptec 1740 card responding as a > 1540 as well? Basically yes. ISTR that you also have to setup a BusLogic card for BSD/OS to not match one of the ISA addresses, for the very same reason. I've had a look at the FAQ, there's a large section about the 742A, but this detail is indeed missing. > I also tried switching the interrupt to IRQ12 with the bt driver > disabled, the EISA probe _still_ thinks that the interrupt is at IRQ > 9, and the boot process halts. That's surprising. I never had problems of this kind with the EISA code. Maybe your mainboard is lying? (Mine was a SiS chipset one.) My Bt742A always ran at IRQ 11 or 12 (i eventually forgot which one). -- cheers, J"org joerg_wunsch@uriah.heep.sax.de -- http://www.sax.de/~joerg/ -- NIC: JW11-RIPE Never trust an operating system you don't have sources for. ;-)
