The POST card should indicate BIOS specific codes. Also, I would only take account of the first two digits of the card, because these indicate the last code. In this case, it's an Award PnP BIOS; the codes at http://www.bioscentral.com/postcodes/awardbios.htm point to: 0D - Program some of chipset's …

CPU warms up, but nothing on screen and I am getting beeps from speaker that might be memory related beeps if beep information I found online and I get same beeps no matter what ram module I put on the motherboard. You need to be more specific about the beep pattern. Are you sure it's memory …

A BIOS image would be helpful for identifying the manufacturer (and potentially the original manual). If any of you can make a BIOS dump, that would be nice.

OT, but if I understand correctly, you need to manually set jumpers on the board to enable/disable SLI? I've never seen this before. Yeah, this is a thing of the early 2000s, the first SLI boards on the market always had those "SLI fingers", which electrically connected the two cards in x8 mode. …

You can always try to reverse engineer it. It's a simple power delivery system, it shouldn't be too hard.

The best you can do is find a reference schematic for the LM431 IC. Finding a schematic for that motheboard is next to impossible.

Yeah, I was thinking the same as quicknick, the board expects PWRBT# to be tied to GND in normal operation and only when you would normally push the power button it gets pulled to 5V. A pull-down resistor should do the trick. LED- may not be GND, make sure its tied to GND when the board is unplugged …

Check the area near the front panel header, you might be lucky and find a shorted/damaged component there. From an electrical perspective, how is the PWR_ON header presenting ? Both pins shorted ? Here is a header from another s478 Soltek board, you should have one of the pins tied to 5V: Capture. …

Yes, the board have the same behavior without the CPU. In fact, the board with nothing on it and just the 20 pins power connector is acting the same. Power on, then 3-4s latter, power off (No POST beep of course) Yeah, at this point it's either the board or the PSU that's bad. If you already …

Sounds like the southbridge is on its way out (the part responsible for handling power on/off to the PSU). Does it have the same behavior without a CPU ?

Don't know much about the history of the system, but fact that the jumper settings on the board didn't match up with the installed CPU doesn't look great :) The WinChip C6 supports 1 of the 2 voltage ranges : 3.52V (3.45V–3.6V) 3.3V (3.135V–3.6V Mine has 3.52 written on it so I guess it expects 3. …

I would suspect maybe the EZ1083CT is bad (from a previous OC or something like that) ? EDIT: Could also be bad capacitors on that rail.

Have you tried an Ivy Bridge processor on a B75 board? I've had really good luck using Windows 98 with a Core i5-3570 on a Gigabyte GA-P75-D3. It has 4 native PCI slots as well as a couple of PCI-E x16 slots. It also boosts the CPU up to 3.8 GHz when using a single core. Unfortunately, my only Ivy …

Boards have different behavior when they come in contact with the 5V standby signal, some power on for a brief second, some don't at all.

To me, it sounds like it boots, then complains about CMOS settings being reset to default (dead battery). I've had this sound combo happen on one of my P4 AMI boards. If you don't see anything on the screen, try a known good video card and monitor. Also try clearing the CMOS.
