Just a shot in the dark in case someone has a manual on this, or, can have better luck than I did on Internet search. I need to put more memory in this machine, it currently has a (1) 3v Sdram in it., I have (2) 3.3v Sdram to replace it with, and, the memory search for this model is said to work. Question is: does this motherboard have a jumper that needs to be changed for the difference in memory module voltage? Didn't see one on the board, but then I have been accused of being blind by my wife. Thanks.
