I'm trying to install a 3C523 in a PS/2 model 80 but the boards keep failing the 3Com diagnostics. (The diagnostics indicate that the boards either have bad RAM or associated circuitry.) The machines have been configured for the 3C523 with no conflicts (the 3Com diagnostics idea of the configuration matches that of IBM's configuration program) and a loopback plug was attached. The 3C523 was configured for external transciever. (The error occurs on the first group 1 test so according to the diagnostics the presence or absence of a loopback plug shouldn't be a factor.) I've tried 2 different 3C523 boards in 2 different machines (a PS/2 model 60 and 80) with the same results. (The 3C523 was the only board in the machines besides the hard disk controllers. I've installed other network boards (baseband, token ring) in both machines successfully.) Changing the memory and i/o addresses using the configuration program didn't have any effect either. The networking software that is supposed to use this board hasn't arrived yet, so I don't know for sure whether the boards actually work or not. Is there anything obvious that I could have missed in setting up the boards? Do the 3Com supplied diagnostics work (The diagnostics and .ADF file used were the ones supplied on a diskette with the board)? Should I try yet another board? Thanks in advance, Peter
