PC Chips i430FX board

Tue Jul 09, 2002 8:16 pm

I have PC Chips Socket 7 board with i430FX chipset and UMC UM8663AF Super I/O. It's neither M506 nor M507. There is no COAST slot and no fake cache - but sockets with real cache chips installed. It's V2.1 and there's Winbond Flash ROM chip installed.

Woow - I thought that the Winbond is standard W29EE011 but it's something more interesting - W27F010......so interesting that there's no datasheet anywhere

27 -> EPROM. Veeery interesting...

27C = EPROM
W27F is 12volt Flash ROM according to some pages like http://www.spacewalker.com/english/faq_e/flash3.htm and also the FAQ here

Might be also EEPROM or just an EPROM and mistake on the page (and all the copies)

One of those days. Sorry...

We might have a M505 there.
I'd like to have a picture of this board (for the lottery) as well as a Bios copy (or at least the Bios-ID string).
Is that possible?

I will scan the board, I can read the BIOS too. The board is dead but the BIOS looks to be OK. Seems that someone tried to repair the board - some components seem to be desoldered and soldered back on (both voltage regulators and one crystal), some traces near cache slots are also repaired. Don't know what is bad (as I don't have an oscilloscope to test the clock signals) but I can say that the regulators are OK and the CPU does not start (no signs of signal changes at BIOS address lines).

BTW.: I have also M918, M715 and M570 - do you want scans? How big should they be? I think that 300dpi is too much

Hmmm.... seems like that board got through th's hands sometime, somehow, somewhere...

It has green mark on the CPU socket - I know that someone marked bad boards with this...

300dpi is quite ok, yes.
It's sad, that is doesn't work anymore...

What about PC Chips Socket 4 board (Pentium 60/66)?

Socket 4, 4 72-pin SIMM, 4 PCI, 4 ISA, FuGu Tech printed on the chipset, EPROM. Too bad that I don't have CPU

I am still trying to find one of those CPUs too. If I find a working one I'll let you know.

The Pentium 60/66MHz board is not there - it needs cleaning before I put it in the scanner

All pictures should be 300dpi with 40% JPG compression.

[edit]
Added M505.BIN - BIOS image from the M505 board.
