And some chipsets which claim to provide such support, do not really do so. Unfortunately, I don't have the magazine here. They tested a whole slew of motherboards, and this was a problem in many cases. Can't remember whether VIA/FIC was one of the bad guys. Of course, it seems like a "correctly configured" system should work. The big question is, whether the manufacturer does the setup correctly. --- Gary Jennejohn Home - garyj@muc.de Work - garyj@fkr.dec.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
