So use any 2 of the 3, both internal is fine as long as you don't use the external. As to termination, the card is at the end if using 1 cable (and thus should be terminated) and is in the middle if using 2 cables (any commbination) and should NOT be terminated. -- Steve Passe | powered by smp@csn.net | FreeBSD
