More fun working on the Ultra2. (Future backup server). I did some updating and such tonight on the memory side of the machine. As mentoned before it posted 256mb of ram when I finaly got to see console on the old beast. I have been digging in my box of Ultra2 spares that I got from someone on the rescue list.
I found one dimm not seated properly in the 2nd bank of memory which was not allowing the full 256 to be seen. It actually should have read 256+64. The 64 is probably the original that came with the box.
After all was said and done tonight I have the following final memory config (unless i stumble upon more). Each bank within an ultra 2 contains 4 200 pin dimms.
bank0 => 256mb
bank1 => 256mb
bank2 => 128mb
bank3 => 256mb
I did not put the fastwide / fast ethernet sbus card in that I located. That will have to wait till later if I decide to put it in.
Also a few great sites with sun part numbers and info:
