I am having the same problem with my serial mouse. I know its old and stuff blah blah but its all I have at the moment.

I asked someone what to do, tried 3 different things, the last one worked. The problem is I forgot the 'cheat code' at boot he told me to enter! It was x*something, like xserver, or xsession or xsystem...etc

It is detected as a ps/2 mouse. I ran expert mode and tried to configure it at tty0 where it is, as microsoft serial and that didnt work...

Tried looking in the cheat code list but the closest i saw was xserver and it requires a parameter, i dont think this other x*? did.

Anyone help?
