When you first turn the PC on hit the delete key when prompted to access the bios setup/CMOS.
under the heading Intergrated peripherals is the settings for the on board serial ports.

Can you see the serial ports listed at the device manager? If so, does it give any problems?

1) Define "are not working".

2) What does "Don't know about BIOS configuration or so" mean?

3) Have you VERIFIED that your serial/COM ports are ENABLED in the BIOS?

piu1977 ... More info needed.
How did you checked in order to statre it's not working? Is that a reliable applicaton? Maybe the device attached to the serial port is not working....
Have you phisically checked for the connectors to be plugged on the motherboard?
Reset the BIOS to defaults (it's an option on the first screen after entering BIOS)
Does the OS see any serial port? (in device manager....assuming you're using Window$) If yes, have you tried removing from Device Manager and let windows reinstall it?

The device is working, it's a mouse.
The actual configuration is 3F8 IRQ4 (com1) / 2F8 IRQ3 (com2). I also tried with auto / auto.
I've just tried reinstalling the ports at the device manager, and then again, manual configuration at bios and automatic.
There still not working

Right now, I have no extra SW at my PC. Just AV, firewall. Nothing that can be "suspicious" of missusing this matter.

Thanks and excuse my basic English

To confirm: Athlon motherboard + serial mouse?

Suggest bus mouse (w/round plug).

Othewise remove any extra IO cards etc.
Disable or remove modem.
Disable unused serial ports.
Try first just one port enabled then the other.

That'll at least tell you what the problem is.

borrow a PS/2 mouse , replace your serial with the PS2 one, let windows detect the new mouse.
Power off and switch back the mouses. Now it should detect the old one correctly.
