    Jumper settings needed for Compaq motherboard 191767-003

    I need the jumper settings and front panel connections for a
    Compaq motherboard 191767-003 that came out of a Presario 5000.

    Any help would be appreciated.

    I'm assuming that you want to know what the pins do on the 20-pin header next to
    the floppy diskette connector. Compaq Presarios of this vintage all use the
    same pinout, because Compaq used a standard wiring harness and connector to the
    front panel buttons. The function of the other 2- and 3-pin headers on the
    motherboard are usually marked quite clearly.

    The 20-pin header is laid out like this, looking at the board with the floppy
    connector towards the bottom:

    x x X x x x x X K x
    x x X x K o x X K x

    where the "o" is an absence of a pin, to match with connector.

    The leftmost pair of large X's are attached to an on-off momentary switch.
    The rightmost pair of large X's are attached to green LED, probably the HDD
    active LED,
    The three pins marked "K" are attached to a tri-state yellow LED, probably the
    power LED with one state indicating a hibernating computer.

    I have the motherboard and wiring harness here, but not a Presario case which I
    threw back in the pile at the town dump, so I can't tell you which LED is the
    power LED and which is the hard drive LED for certain.

    The other pins on the header are not used on a Presario. One of the pairs may
    do a hard reset the motherboard, but the Presario chassis has no reset button.
