3.3V or 3.5V linear regulation is done with a pair of medium power transistors.

@Jan -

The only way I will be able to do that is if I hand the board over to a "professional" solderer...which would be easy if I was still working at my previous location. Sad

I'll check for the BIOS though.

I would be interested to know if anyone else has this problem with their PM7900 (Rev. 1.3 IIRC).

Thanks.

PS - I purchased an HP 0950-3188 (Delta 0552806A) which will run an MMX CPU. You can search HP Parts for a description of this VRM. Cost is $20 US...though I got mine surplus (BRAND NEW) for $8 US. Wink

@Jan -

Did you patch the "L" or the "S" BIOS?

@KachiWachi

The original 12/07/98-i430VX-2A59GHTBC-00 BIOS I used only says: PC Chips M-520 (Rel 1.1A) but I believe it is a type "S" BIOS.

When I dig out my copy, I'll send you the "L" version (and whatever else I have).

Thanks.

@BiosMan

I use the bios flash (DOS) of award and it send me this error: "unknown flash type"

@agus2009

Send you the patched M520 BIOS and flasher with instructions by e-mail.
Please let us know how it works.

It should...as I have used it on this board before.

What are the markings on your BIOS chip?

I'd say a H.T. Chip AKA Macronix MX28000, probably MX28000PPC. Award Flash should detect him properly. Uniflash had always problem with these chips, even in the latest 1.40 version.

If awardflash fails to update because of the changed bios-ID use the following syntax:

awdflash bios.rom /py /sn
-> modify it to match your filenames

If it still posts the message try a different version

I try this "awdflash bios.rom /py /sn" but it says that again

@ KachiWachi

I don't understand what do you need

my bios id is this (I think) 03-03-1997-i430VX-02071997C-00
