i'm going to guess i got it back on the flash, indicating there was some value in doing it, that there was something stuck in the bios.
gamers may have specific reasons for ps/2, but i'm not a gamer. for me, it just gives me back an extra usb port, that i can plug into another piece of hardware. there's four on the back and two on the front, which was a lot for the time. if my ps/2 isn't working, i have to use two for input devices; i get those usb ports back if i can use ps/2 slots, instead.
this could also, in theory, make the usb more stable, but i think that's obscure.
was that the problem? well, it hasn't crashed since i swapped it.
