Hi everyone. Got this board with a rather strange jumper arrangement for setting the CPU voltage.
The twin jumper JV1 (right above the CPU socket in the picture) seems to be switching between +5v and whatever the VRM outputs, and there are four other jumpers in each corner of the socket (JP3, 4, 5, 6) that connect the CPU power plane directly to +5v when shorted. However there are no jumpers to choose what voltage the VRM puts out...

All of the jumpers are documented on the board, except the ones i mentioned and two others labeled JV2, JV3 that are near the VLB slots and i'm certain they got nothing to do with CPU voltage. I searched the net and there is nothing about this board to be found ...
