OK i just fitted a gatway motherboard and its running fine, if this is the board your looking for the pin outs on then i have listed all numbers on the pcb/motherboard so you can make sure its the right one.

All these nubers can be found on the pcb/motherboard.

E139761 - Next to the ide ports bottom end.

4000622 - Next to the ide ports bottom end on a sticker with bar code.

N232 - Next to the floppy drive port bottom end.

IMEA02400315 AA A19243-204 - Below front panel pin bottom on a sticker with bar code.

Remember that pin one on all jumpers is maked with a small white triangle.

The front panel pin block for this pcb/motherboard is a 16 pin block at the front side under the floppy drive port.

Front panel pin settings:

HD Led - 1,3
Power Led - 2,4
Reset - 5,7
Power On - 6,8
IR - 11,13,15

Hope this helps.
