Hi

I'd like to add the onboard voltage regulator. I think its a good board with good bios and it's worth the effort.
There are severeral versions of the board. Mine looks as follows:

Does anybody have an identical board with populated regulator circuit and could provide a picture of it?

Where does the voltage regulator go on that board?
I don't see a reference to an add-on regulator in the manual either.

Oh, now I see. It looks like it is missing from your board. Strange.

Maybe it was never soldered on because of cost reasons ? There are many 486 motherboards out there which are prepared for a regulator but the parts are missing :(

"Shuttle" doesn't ring a bell, but do either of these (http://www.sydex.com/temp/486mobo.png) look like it? I think I might have one buried somewhere.

Now that I look more closely, I see that your board isn't the same as mine--but neither is it the same as the ones shown. These Opti boards, no matter who the maker was, underwent lots of changes. The two I posted are in the same manual--one can take only 5 volt CPUs; the other can take 3.3v but only with an add-on regulator board. A still later one has the regulator built in and can handle 4.0, 3.45 and 3.3 volt CPUs.
