FreeBSD only ever configures them for PIO during bootup, but, using the atacontrol program, it configures them both for maximum speed, even knowing they _can_ only do UDMA33,WDMA2. -- Bruce Cran To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
