[rescue] SPARCEngine 1E and VME Memory Boards

[Richard]

Hi folks

Looking for some suggestions/guidance or help.

I am Looking to add 2x 4Mb Sun 3/E memory boards to the SPARCEngine 1E.

I do note that these are memory boards from the Sun3/E but am of the understanding that they will work.

Reading through the SPARCEngine manual I have added the jumpers to my schroff Backplane to bridge slot 2 as this is empty - the sbus video card occupies the slot.

Configuration is
Slot1: SPARCEngine
Slot2: jumpered and empty
Slot3: 4Mb memory bord jumpered for 4-8MB
Slot4: 4Mb memory bord jumpered for 8-12Mb.

Now on post I don’t see the extra 8mb.

Anyone got any ideas ? I read something about telling the nvram about the VME cards but not familiar with that process or how to do so.

Thanks in advance 

Richard
