For those who are interested in this: I found out where the serial connector is.
It is near the Power button "SW1" and its pinout is as follows:
Pin 1 = +3.3V
Pin 2 = RxD
Pin 3 = TxD
Pin 4 = GND

Maybe someone can confirm those?
I have neither a 3.3V serial cable nor any spare MAX3232 lying around, so I cant check.

Bleep

Meanwhile, I can confirm this pinout - I've got a serial cable now.

Ok i've got the cable, connected it, tried and got no output…
Well no output from rom, I have already managed to disrupt the system on harddrive so it won't boot anymore :)

Output from ROM ?!?!
I am not aware that there is any output from ROM !
The only output that I am aware of is the getty process running once the system completely booted up

Actally there is output to console before system is booted. I've found out that i soldered connector wrong and now i get output:
