The motherboard is an A7V333 (new board) that has a VT8233a for south bridge which supports ata133 (aka UDMA 6). The bios indicates the drive is UDMA 6 enabled. My original email suggested that maybe FreeBSD doesn't detect/understand the VT8233a and is reverting to UDMA 2 - could this be the case? the atapci0 line reads: Apr 27 18:48:34 pc1 /kernel: atapci0: <VIA Apollo ATA controller> port 0xb400-0xb40f irq 0 at device 17.1 on pci 0 I am 100% sure there is an 80pin cable in. I tried a 40pin cable and the bios immediately detected the difference. I also tried another OS. Oh well any/all suggestions would be useful...
