Its correct.

Compaq is selling replacement for $25.00 or $20.00 each, depending on whether it is P/N 157126-102 or either 157126-102 or spare P/N 191767-102. Why is that?

The variations on the part number are like Rev #s of the board. They are probably trying to get rid of old stock.

The puzzle is proc BMW?

Motherboard label has 0001 30 BMW made in china. Also has barcode label 071384HA BMW-2. Then there are two labels 0106 and 686 C3.

On the pci slot "Replace with Compaq spare proc bd w/o proc BMW", " Spare No. 191767-102 Part no. 157126-102".

proc = processor

IE - Compaq BMW motherboard without the processor.

BMW motherboards were used in a number of Compaq Prosario 5000 series computers, such as 5007US, 5080US, 4100CA, 5100uS, etc. So the processors are known. Were there any Via C3 processor versions, only the bios knows?

I have received an email asking about the pinout for USB on this board. The only header on the motherboard J1 is comm2. Rear USB is standard on ATX motherboard.

This is an extremely interesting motherboard and is sold from Compaq replacement depot for either $20.00 or $25.00 depending on P/N. It is a bargain.

There's a manual available for this board here:-

Thanks for the manual. The manual says PPGA.

The puzzle is what is the processor limitation? What is BMW processor? Is GTL= Tualatin? Or did the 0106 date coded bios include all the core voltages down to 1.2v and multipliers up to 16.0x? Is 686 C3 Via processor and core voltage can support also the fcpga cpus?
