How about QUIRKS: The ata driver has some issues with the Apollo MVP3 chipset. Drives work only in pio mode and must be set to pio mode early int the boot process. Do not upgrade. If you must upgrade in the face of this, add /sbin/sysctl -w hw.atamodes=pio,pio,pio,pio to the start of /etc/rc.conf. Even if you do this, any and all damage to your system is at your own risk.
