I just received this pretty nice 440BX motherboard:

It was more or less an impulse buy, it came with a stick of RAM and 400MHz P2. At first I thought it is one of the countless similar 440BX motherboards and I wasn't too excited of it, but this actually has quite nice OC features and according to this, it should also support Coppermine:

It is not Abit BH6 which I have, but I'd say that is above average as far as CPU support and controls go.

I haven't tested the board yet, but seller had photos that it is functioning and could pass at least some tests. It has had some recapping work done at some point. Although soldering job isn't the worst, it is not well made. Most of the caps are some low end stuff mix and mash and majority of them are either too wide, tall or both (most caps should be 8mm diameter and most near slots should have the typical 16mm at tops).

I've recapped many boards and cap values that are installed in this feel weird to me and I think who ever made the recap used larger voltage or even larger capacitance caps that is perhaps on the original board. Higher voltage rating doesn't hurt, but using higher capacity caps can change the circuit operation significantly and introduce all sorts of weirdness which might not show up during a short test run.

Does anyone have this board and could someone bother to make a map of the caps so I could actually match them better? Thanks.
