Hi again!

I've just recently fixed my GA-586 mainboard thanks to help from you guys.
Please excuse for another little request. Does anybody have a clue how the PS/2 header is wired?
It's a 4 pin header, with only VCC pin being marked.

There's a pinout for another GA mainboard shown in this thread, but it doesn't seem to work, however:
PS/2 mouse port on GA-586HX rev. 1.56

Here's another one, with data/clock position switched:
Gigabyte 586TX3 - PS/2 Mouse Header

Any idea welcome.

Best wishes,
Jo22

PS: I forgot to mention, PS/2 port is enabled in Setup.

Quick update! I got it to work!

I had to have the PS/2 mouse connected during power-on!

Previously, I didn't do that because I was afraid of shorts and wrong pinout.
I had the PS/2 mouse connected shortly before running mouse.com, each time.

I've attached pictures, maybe they're helpful to others! 🙂

PS: The PS/2 port is quite sensitive, when I switched on my Weller soldering station (trafo based) the PC made a ticking sound and the mouse cursor froze.
Despite them there no physical contact. Must been some EMI..

Oh, and please be careful with PS/2 pinouts from the internet!
Sometimes the pins of VCC and GND on the PS/2 motherboard connector are switched (I mean the green/black/pink connector, not the pin header)!
So better use a needle and a multimeter to double check!

In my case it's like this: VCC is orange, GND is red, black is CLK and brown is DATA.

(The cables on the pin header connector are black, brown, red and orange; from left to right)

Edited.
