Hi - I fought this battle for a few days and managed to get it to work.
Now that it works it is *really* nice - so it was worth it. :-)

I used the default configuration for configure adapter.

I have heard that you might want to select interrupt pin C but I didn't
have to.

Configure device:

You might want to initially turn off sync negotiation, disconnection,
and fast transfer depending on what your disk can do.

Enable bios send start for the devices you have.

Advanced options:

disable DOS space > 1gb

Now motherboard:

L2 cache fastest
Cache burst r/w cycle 2T
Memory shadow video disabled, option ROM's disabled
PCI master access shadow RAM enabled
CPU to PCI burst write enabled
CPU to PCI post memory write enabled


Finally:

Some of the older scsi-2 drives (like my HP) won't boot from the
buslogic controller.  I had to switch temporarily to a seagate hawk
in order to make my boot disk.  I use the HP as a data disk with
the buslogic just fine.

Hint:

Use the boot floppy as a debugging tool to make sure the kernel sees
the card and that the settings look right.

Good luck!
