Okay, here's my problem. I think this has been asked before, but
I threw away the answer.
I have had (for some time) a Buslogic BT-958 controlling two wide drives,
two narrow CDROMS, and a narrow hard disk. This is fine. I want to add
a narrow drive and my ZIP drive to an Adaptec 2940 (I know poor choice,
but it was laying around). The SCSI chain on the 2940 is to be all external,
not that that makes a difference.
Well, you probably already know where I'm going with this--the Adaptec
BIOS shows up first I guess, and when drives connected to it are powered
on, the BusLogic BIOS says "Target 0 installed as second disk", "Target 1
installed as third disk", etc. LILO then proceeds to freak out, and it
doesn't really work. I imagine that the Adaptec becomes scsi0, and
then things have problems. Is there a way to make the BusLogic BIOS
load first, so that it is not confused by the Adaptec? I will never boot
off the Adaptec (always of the BusLogic), and sometimes the drives on
the Adaptec may not be present.
This all worked when the 2940 was not there and a Adaptec 1502E was in
its place, running only the ZIP drive. I guess I could put it back
and run that chain off of it, but I wanted to run "real" 50pin SCSI
to the other drives on this chain.
