Hi to all,

Need a bit of help from someone who has/had a Gigabyte GA-586HX mainboard and knows the pinout of the onboard PS/2 mouse header.
It is a 4 pin header, not the newer 5 pin header, and I have only the 5 pin cable(ok, there are only 4 wires, but in a 5 pin socket...). Here are some pictures:

The attachment GA-586HX_mouse_header.jpg is no longer available

Couldn't find any info on the mainboard mouse port pinout, not even in the manual.
On the mainboard it is printed only MOUSE VCC and pin 1 in marked...
I took some measurements with a multimeter and on pin no. 1,3 and 4 I've got 5V and pin 2 is GND.
Can I assume, that pin 1 in Vcc? Can I fry something on the mainboard if I connect CLK and DATA to the wrong pins(between pin 3 & 4)?
I really want to be able to use a PS/2 mouse so I could hook up this board to my KVM...

Thanks !
