Re: Acer PICA memory type

Bob,
 This was the trick. The 4x36 simms I have worked fine. The machine was set
for 2 8MB simms, while I had 4 4MB simms. Explains why it failed to post
after exactly 4MB (it looking for another 4mb).

 Thanks again, Strange to see the machine boot into WINNT 3.1.. Ahhh Program
Manager....

Chris
