That's real. /sys/dev/buslogic/bt.c:bt_port_probe() contains: ... if (bt->model[0] == '5') { /* DMA settings only make sense for ISA cards */ ... } else { /* VL/EISA/PCI DMA */ info->drq = -1; } so I assume the probe message is correct and reasonable. > >> bt0: BT-445S FW Rev. 3.36 Narrow SCSI Host Adapter, SCSI ID 7, 30CCBs >> bt0: Using Strict Round Robin Mailbox Mode > >Hummm...

The only comment I can find is in bt_isa.c:bt_isa_attach() - which refers to a hardware bug in older h/w revisions (I'm fairly certain I have a RevD card - which is affected). F/W 3.37 only runs on RevE cards and is being used to guess the hardware revision. This bug only affects cards where the BIOS is enabled - and I don't have the BIOS enabled so it shouldn't affect me. >> I noticed that enabling the card BIOS makes it just lock up after >> the "card found at 0x330" message, but I'm not sure if this is >> just because it can't find any SCSI disks to boot. > >If the BIOS won't come up that sounds like something outside of FreeBSD >drvier issues. I tend to agree, but I'm not sure how the card is expected to behave in this situation. The manual only discusses booting off SCSI disks attached to the card - which I don't have. There's no indication of what would happen if the BIOS is enabled when there aren't any bootable disks. I was hoping someone else might still have a system with a BT-445 and be able to confirm the normal behaviour.
