That would be awesome thank you!!
Does your board reports the ports?
Also is the IDE interface working?

Sorry for the delay, I was away... the IDE controller is working but very slow. I have to check for serial and parallel under windows if correctly detected. For the pinouts I check as soon as possible.

Thank you for that! I still don't know why IDE on mine is not working.
For the ports you can also use some DOS reporting utilities I guess
like Norton System Info

Here the pinouts:

Small COM
(Cable header view) - (DB9 M connector view)
X 2 3 4 5 - 1 2 3 4 5
6 7 8 9 10 - 6 7 8 9
X -> X ; 6 -> 6
2 -> 9 ; 7 -> 8
3 -> 1 ; 8 -> 7
4 -> 4 ; 9 -> 2
5 -> 5 ; 10 -> 3

Large COM
(Cabel header view) - (DB25 M connector view)
1 2 3 4 5 6 7 8 - 1 2 3 4 5 6 7 8 9 10 11 12 13
9 10 11 12 13 14 15 X - 14 15 16 17 18 19 20 21 22 23 24 25
1 -> 1 ; 6 -> 18 ; 11 -> 6
2 -> 15 ; 7 -> 4 ; 12 -> 23
3 -> 2 ; 8 -> 20 ; 13 -> 7
4 -> 17 ; 9 -> 5 ; 14 -> 24
5 -> 3 ; 10 ->22 ; 15 -> 8

LPT
(Cable header view) - (DB25 F connector view)
1 2 3 4 5 6 7 8 9 10 - 13 12 11 10 9 8 7 6 5 4 3 2 1
11 12 13 14 15 16 17 18 19 X - 25 24 23 22 21 20 19 18 17 16 15 14

3 -> 3 ; 8 -> 16 ; 13 -> 8 ; 18 -> X
4 -> 14 ; 9 -> 6 ; 14 -> 19 ; 19 -> X
5 -> 4 ; 10 -> 17 ; 15 -> X ; 20 -> X
Plus pins 19 to 25 of the DB25 are connected together.

Both COM ports and LPT port are detected by BIOS at boot up and under windows.
I tried using the DB9 COM port with a serial mouse without problem.

Thank you so much for all this. 😁
I'll try connecting something in the future
but for now my bios doesn't show any port at all

Can maybe any of you upload their Bios here?
I suspect this might be the issue with mine

Thanks for your efford
