Serial mouse during unattended setup

Hi,

I have a problem, I install my NT system unattend.
I have a PS/2 mouse connected, and a serial coonection to the UPS.
When I install NT everything goes well, all the apps go on, no problem.
The mouse (PS/2) works as well.
When I then try to install the UPS software, everything goes well, but when I reboot, the system comes in NT with a message that a new device is found, a PS/2 mouse.

I can resolve this by changing the value manually in the control panel under the mouse section.
This is no solution for the unattended setup.

How can I resolve this?

Thanks ina dvance,
