    Hi I had a bricked mobo and in my search to ressurect it i had the same confusion as yours. I found this information from the following link. But the link is not working for some reason but i managed to getthis from googles cached pages hope this wont be too late for you.

    HP
    Compaq SPI
    Header
    Pinouts
    Besides the HP-Compaq SPI header pinouts being a NON standard format.
    There is also a jumper accross pins 1 and 2 which
    needs to be removed before attempting to connect the programmers ISP
    lead to the SPI Header.
    I was able to map out the 6 pins needed for programming using a
    Multimeter. Pinouts are as below.

    SPI
    Header
    Pin 1 -- No connection needed
    SPI
    Header
    Pin 2 -- CE
    SPI
    Header
    Pin 3 -- SI
    SPI
    Header
    Pin 4 -- Not Present
    SPI
    Header
    Pin 5 -- SO
    SPI
    Header
    Pin 6 -- Vdd
    SPI
    Header
    Pin 7 -- SCK
    SPI
    Header
    Pin 8 -- Vss

    My addition
    ====================================================

    2 4 6 8

    1 3 5 7

    There is no pin 4 and there is a jumper across 1 and 2.
    ====================================================

    Connect Programmer as above, programmer software may complain that
    two pins are missing but they are not needed to erase, blank check,
    program or for verifying the onboard Device.
    After programming, the jumper which was removed from pins 1 and 2
    needs to be refitted. Our example of the M2N68-LA worked fine after
    reprogramming the BIOS Chip Via the SPI header.
