Socket A schematics - any board with VIA chipset (KT400A if possible)

[N²x²N]

I can't find schematics for any socket A motherboard, probably my mistake in search terms.

I'm troubleshooting a KT400A based board and would like to try something but I have no schematics to at least give it an attempt.

Most important is the power on schematic.



We try until we throw the towel.
