So, the current machine I'm messing with has this VRM...thing...on it. I have no damn clue how these things worked back then.

Here's the board for reference:

Anyway, from what I understand, the white jumper block thing is the VRM and controls CPU voltages. The board it supposed to be able to support MMX chips when the VRM module is present. My board does have the white jumper block installed, with some jumpers set within it.

Would anyone happen to know how to set the board to accept an MMX chip with the different voltage settings? The manual I found for the board revision I have only lists 3.3v and 3.5v.

Any help is GREATLY appreciated.

Thanks for humoring me, but your first link is just a mirror of the link I posted, and the board you mention is almost, but not quite. I think they are just revision differences though.

Either way, still stuck.
