I recently bought a PS2 mouse and a PS2 adapter. I fitted the PS2 adapter on the motherboard,and connected the mouse. Went to the bios and enabled PS2 mouse. When I rungpmconfig the keyboard locks, when i go to the bios and try to use the mouse, the keyboard locks. And yes I'm sure I put the adpter in the right way (I checked the manual) and I hvae tried it the other way around to. The mouse work on other computers.. Any ideas....? /nisse
