Workgroup Server 95 (Quadra 950) Setup/Doability

Hello again says an old AWS95!

It's one of Apples fastest 68k machines, as you all probably know.  
I'd like to get OpenBSD 3.9 running on this machine and put it on the  
Internet.

It's not possible to use ADB, it says. So: How exactly do I install  
BSD? Is there a serial console waiting for me somewhere?

I could attach a Terminal to both serial ports.


Thank in advance,
Falk
