Well, this turned out to be a two-step solution - not only did I have to
flick dip switch 8, but I also had to get Solaris 2.3 to recognise the card -
this required running /opt/SUNWdiag/bin/sundiag to get it to see the card
(boot -r would not see it :-(

------- Original Message:

We have an old ethernet SBUS card that we wish to use. It's one of the ones
with a BNC and an AUI connector on the back. The only identifier on it is
'S4 Ether'. It used to be used with the BNC, now we want to use it with the
AUI connector. There is a block of 8 dip switches on it, that are all pushed
towards the back of the machine - what should they be set to to enable the
AUI port, instead? We tried switching all 8 over, then the machine can't see
the card at all...
