Have you tried using one of those $5 ISA/PCI POST

I'm aware of them, but I did NOT know they were that cheap...
*searches*
OK, so for $20 I've just netted myself a set of three -- a PCIe/MiniPCIe
one which should work nicely on the laptops and the spiffy new(ish)
desktop, a PCI/USB/parallel one for the other laptops, and an ISA/PCI
one for the 386.
(Well for $6 a piece, it's hardly worth *not* having the full set...)
I was
working on a Pentium motherboard a few days ago that wouldn't even beep.
... which is pretty much what the 386 is doing (or not doing).
After checking the onboard fuse I plugged in the post
card into a PCI
slot and all the voltages were there (except for 3.xV which is normal)
Why would it be normal for 3.3V to be missing? Was this an old board
which only supported 5V PCI?
Most battery leaks tend to take out the keyboard lines
which are in the
general area. Never had an issue with washing a motherboard with soap
and water and letting it dry in the basement for a day or two. If
something major is shorting the AT supply should not run.
I can't see any damage to the keyboard lines... I did resolder a
resistor in the battery-charge chain, and scratch some corrosion off the
battery feed track. The keyboard connector got off pretty lightly it seems.
