Successfully revived the second of three industrial P4 motherboards I've been working on recently. This one is an Advantech AIMB-742 board, one of a pair that I have.
I replaced the KZG capacitors with polymer caps. Four of the six had been leaking and were toast. I also had to replace some components I'd cannibalized while trying to fix another AIMB-742 motherboard.
The board does have some nasty rust on the chokes near the CPU socket and MOSFETs. Even so, the voltages all test normal and the board booted up just fine.
