Driver SM bus Controller su macchina IBM

[zapping]

ciao

ho un problema: non riesco a capire

a - come trovare i driver
ho consultato il sito ufficiale IBM e non ci sono, in rete non li trovo per XP x64

b - e' fondamentale installare i driver? o posso campare anche senza il driver per l'SM bus controller?
