My P3 1G machine would not allow Win98SE to install properly with a USB mouse - just would not recognise a USB mouse during setup so I had to use the keyboard, which means that you can't setup everything easily first off - I needed a PS2 mouse for it to be recognised during install setup. Once past that, I could attach a USB mouse.... so I just went with the flow... still have the PS2 mouse & keyboard cause it's less fighting when I may need to do a reinstall (most likely eventually!)...

go figger....
