The motherboard is a PC Chips M960G https://theretroweb.com/motherboards/s/pcchips-m960g chipset SiS661FX, s478, with a celeron-D 335 on it and 512MB of DDR-400.
There is no video output from either the IGP (SiS315) or from an AGP card. No beep codes. Keyboard LEDs don't flash when I power it up.
The codes on the POST card mean "reset signal was detected 3 or more times" and I get consistently the same code on power-up. The CMOS battery is new, just installed.
When powered up, the chipset does get warm, so does the CPU (it's a PresHott after all 😀 )

(I basically bought that just because I didn't have a s478 mobo with SiS chipset and was curious how it performs)

Pull battery.
Wash.
Dry.
If no change, try bios recovery procedure.

The motherboard has already been cleaned (not that it needed to be, it was very clean to begin with)
I do not know the BIOS recovery procedure for this motherboard.

My colour vision sucks but I swear that is a really nice pink PCB or is it red ?

It's light red!

It's red.
I tried a generic AMI bios recovery procedure; it doesn't work because the motherboard doesn't even try to access a floppy drive at power-on.

Bios is removable at least.
Got another board for a hot flash?

No other board with this type of socket. And while I do have a TL866, I do not have a PLCC32 adapter for it.

Well at least the adapters are cheap.
I still say wash it again.
Dishwasher with no soap has fixed quite a few dead things for me.

Multimeter?
Caps all look OK?
Components all look undamaged?

Pics?

Tried forcing a checksum error? I'm not really sure if it applies to AMI, but usually forcing a checksum error by shorting address lines employs a bootblock of some sort I'd assume? At least I know Award does that.

Caps and all components look fine, the board overall looks pristine and almost unused.
Well I ordered an adapter, and as is the case with ebay purchases it'll get here between next week and next year. 😀
(the adapter cost half as much as the whole motherboard; $8 including shipping, and I paid $16 for the motherboard)

Oh 🤣.
I was thinking more like half that

You know what .. it looks like a pink colour to me and yup its weird but I do like that colour for PC parts, weirldy have a Iwin case for a ITX PC that is pink.

Today's scores:

- NMC 5VMMX - interesting SS7 ATX mobo, needs caps.
- Quantum Sirocco 2550AT - dead unfortunately 🙁

5VMMX is an interesting name for a SS7 board!

Runs 5volt CPUs and support MMX cpus perhaps.

Indeed it is. The EPoX counterpart is 99% this:

https://theretroweb.com/motherboards/s/epox-p … ix-ep-51mvp3e-m

The only difference on mine is the VRM, slightly. That, and it asks for some strange BIOS password... no, the specific EPOX BIOS password doesn't seem to work.

Upside: 1MB cache!

All in all, I might make this my main MVP3 board - I have a K6-II+ 500 waiting for it, as well as some nice period-correct drives 🤣

Yes, but don't all SS7 boards support MMX? If so, that's what makes it a bit 'funny'.
5V socket 7 CPUs don't exist.

True . .it was just a guess based on the name, It does make sense aside from the points you make 🤣

Nice!
Still can't believe even these are hard to find now. 7-10 years ago when I used to browse the bay, these were at rock-bottom scrap prices working or otherwise, particularly the PCI-E versions... because, who'd want a top-end early PCI-E card? 😁 And a little before that, AGP cards like the Radeon 9700/9800 were in similar waters. Can't tell you how many R300 GPU's I've passed that were going for no more than $5-10 (and sometimes barely even making it over $1).
How times change.

hrmmm has dead in the image file name ...not a good omen 🤣

Haha, that's a hilarious find. 🤣
I'm willing to bet that it does work. Seems that ATI kind of started learning their lesson from the # of dead 9700/9800 GPUs. So for the x850 cards, the "dust blower" fan and heatsink assy. they used was much more inline with the TDP of the card.

Maybe it's an indication that these cards are prone to dying. Like the 9700 pro, they were super popular but most have failed due to the heatsink lifting itself away from the die. 🙁
