My system is complaining that I do not have a UDMA-66 compliant cable
attaching my hard drive to the mother board. I am in fact using such a
cable, and I have already purchased another cable and tried it just to
check that the fault was not in the cable. The excat error message is
from the kernel is :
ata0-master: DMA limited to UDMA33, non-ATA66 compliant cable
What could be causing this, and how can I fix it? Is there a kernel
option of something I need to have setup? A sysctl option? What does
ata66 require in FreeBSD? uname and dmesg below.
