my machine . other 2 are FC5 and xp . i am using common one set of keyboard
, mouse and monitor for every cpu through  KVM (model REX-420  )  cpu
changer . the problem is whenever i change to other os then go back to
freebsd the mouse does not work . to change cpu i need to press "Scroll
Lock" 2  times then  the number (for me 1-freebsd ,2 -xp ,3 -FC5 ) .  i also
