Help, again.

I'm trying to get a 5000/150 working with 8meg SIMMs instead of with
2meg SIMMs. 

The same CPU module that wouldn't work in a MAXINE chassis (8meg
memory) but which worked fine in a 3MIN is also refusing to work in a
3MIN chassis when I upgrade the memory.

Does anyone else out there have a 5000/150 with the 8meg simms?
If so, how are the switches on the CPU daughtercard set?
