I add the same problem on a ASUS K7 motherboard and the reason for it was that the IDE cable was not "ATA-66 ready". These cables use twice as many connectors as the "classic" IDE cables. When freeBSD boots it correctly detects the chip set and the disks, but does detect the fact that the cable will not support ATA-66 until it tries to access the disk. It then falls back to PIO-4 mode. Good luck, Patrick. To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
