Can anyone think of any reason why a BusLogic bt747 doesn't get 
probed on an i386 machine?

My config file says:

bt0     at isa? port ? irq ?
scsibus* at bt?

which is stolen out of the GENERIC config file.

Anyhow, if I config it as an aha0 the thing works fine (but as an aha
which is less than optimal for this EISA card)...

This thing *used* to be in a NetBSD 0.8 machine about 2.5 coons ages ago
and I've just now pulled it off the shelf and tried to do something with 
it.
