Unknown Socket 7 Motherboard, Catch 22

Was given a previously working Mobo to replace my bad Compaq one. They are the same form factor so it is a drop in.

Am posting this because the Mobo docs were lost. Am trying to determine what the start connectors are because while the front panel connector is printed on the board (2 rows of 12 pins with 3 missing pins) there is no list of start and other functions.

The Mobo has an Award BIOS so was told that can use it to trace the Mfr and other info. On the bottom ISA connector is a label with Award 1998 PCI/PNP586 146680663 and another label with S/N:M990113475. The upper left area has FI (in a squashed circle) 4-V-0 and 0299 (in rectangle).

Used Wimsbios

but my Award numbers do not match the format.

The Catch 22 is that the correct Award numbers come from the BIOS screen "The AMI or Award BIOS id appears at the bottom of your screen after power on, during memory count up. The PAUSE key should work at that point, allowing you to write down the BIOS number, the BIOS date, and the version. You must copy it exactly." which I am unable until determine the start connectors.

Would be Very Interested in any suggestions.

Thanks

WRONG :-)

One of them being Compaq (or Dell :-) should raise serious suspicion on being 'drop in replacable'.

If the new board is a 'standard' board, use a standard PSU to fire it. Then you can watch the bios screen and/or run identification software.

Forgot to mention that the Compaq PSU was also nonworking. The complete story is "Bad PC PowerSupply or MotherBoard?"

I now have a new standard PSU but as previously mentioned do not know which of the front panel pins are the start ones so would like to track down the documenation for this unknown Mobo.

Am not too anxious to just start shorting the front panel pins!

Thanks for the links!!

This unknown Mobo does not seem to have the same front panel connector because it is 2 rows of 12 pins with 3 missing.

I was able to upload 2 photos to imageshack.

Major features of the Mobo are:

Ali Chipset (M1541 and M1543)

ESS Audio Drive (ES1869FC M468)

Socket 7 (CPU is AMD)

Memory is 2 DIMM slots

AGP slot

2 PCI slots

2 ISA slots

Std 2 ISA and Floppy connectors

has made in Taiwan above the Socket 7

With power removed, use a multimeter to determine which pins are grounds. Then with standby power present, determine which pin has

+5VSB. The two should be adjacent to each other.

Please provide more details because what you listed could apply to many SS7 motherboards. The model number may be printed around the periphery, between the PCI or ISA sockets, or even on the bottom.

Thanks for the Excellent Tip!!! I did as you instructed, found the grounds 1st and then checked for +5V. When I found it the PC started.

Maybe I have never seen their Logo. Will check it out.

just short out the front panel pins with a screwdriver. never in 8 years of IT has this ever caused any damage for me, and the reasoning behind it is that out of the FP connections, the speaker, power led, reset switch, green led, hard disk led have no voltage across them whilst the machine is switched off. the one remaining pin pair - the power switch does have a small voltage across it, but not enough to cause a damaging current to flow back into the other pins if shorted.

The other way to power on the machine, is to use a paper clip or some other low-tech solution to short the green and black wires from the power supply to the motherboard. although this doesnt always work, but again its never caused any damage for me.
