has anyone had contact with such main board? it is a clone of XT but with the AMD 286 proc. The problem is that no boot image comes out, I tried on 3 ISA graphics cards (I marked them as working before, so I had to test them before). I thought maybe it was because the disk is not plugged in so I put on the "QUICKPATH SYSTEMS portfolio io card" but unfortunately nothing. Anyone have any idea?
Solder points looks fine, no electrolyte swollen, no signs of mechanical damage.
voltages at ISA slots are correct
