I thought I'd ask here in case anyone was familiar with these machines.
I have a NetServer E60 which was kindly donated to me. Dual Pentium 3 450MHz machine, quite nice condition.
Only issue is, the board seems dead. 1 long, 2 short error beeps on power-up (which apparently indicates some kind of option ROM checksum failure and the manual suggests to replace the mainboard).
I went through all the basic troubleshooting steps, including clearing BIOS, replacing the battery, removing all cards. trying different combinations of CPU/RAM, and powering it up outside the case. Nothing works, so it does seem that something on the board has actually died.
The only removable chip is in a 28 pin PLCC socket with the label "PBNC1 4.06.13", which I assume is the BIOS/CMOS chip. Everything else is soldered to the board. But I don't have the appropriate hardware to read it out or re-flash it.
Any suggestions where to go from here before I try and source a replacement board?
The part number(s) of the board is D7140-63000 / D7140-69000 (because HP love separate part numbers for spare/replacement parts).
