I picked up this CL 5428 VLB card.
I'd like to figure out what the two jumpers do. I got a tip that one of them might be IRQ related, and the other possibly bus MHz related.
On several 5428 boards the jumper J11 seems to correspond to "IRQ9 enable" (closed) and "IRQ9 disable" (open). I assume this would mean with the jumper closed the card would use IRQ 9, and with it open it would use... some other IRQ?
And what about JP12?
Anyone have any more information or educated guesses?
