I have is cool socket 3 motherboard in my collection.
https://theretroweb.com/motherboards/s/ ... -ver-1-3[b][/b]
Currently equipment: Intel DX2-66 and 8MB Ram, ISA i/o controller with all obvious stuff.

It runs mostly fine but has some issues.
When powered on, the system hangs. Post card says 07 on Award bios (checking bios). When I press the rest button it just works fine. What is this issue?

Next, there 256kB cache mounted: 9 15ns chips including tag. When set for 256kB the system hangs on the bios summary and refuses to load OS. When jumpers for 128kB is fine.
Now here's the thing: cache works fine in another board, swapped the chips in and out, cache seems fine. Other good cache chips, same behaviour.
Strange, right?

Finally, my known good Diamond Speedstar Pro (VLB) won't run any vesa mode stuff and comes with errors. In plain vga modes it's ok. In another system it's just fine in vesa.
When switching to my whatever-happens-oti077 even quake runs the benchmark fine.
