damnable mouse won't work

Hey all,

I'm having a problem with a new CentOS box I'm trying to set up and it's mouse. basically the install goes fine but the mouse won't move! the box is a 2.4Ghz P4 running on a Asus motherboard with 512Mb and the mouse is a bog standard PS2 effort. I've tried reinstalling the OS, installing the pervious version and trying different mice - no luck. I was begining to think it was hardware related but i've managed to use a knoppix livecd ok on that box as well as install in win2k (steady!) with no issues.

has anyone heard of any issues along these lines? I can only assume it the motherboard and not something serious, but if anyone can help they'd be most welcome. :D

Tim.

Do you have any other mice to test this with? A USB one perhaps? Or another PS/2 to make sure it's not the PS/2 port itself?
