I'd like to know how the FreeBSD 4.2 kernel detects the kind of IDE cable
that I am using. The snippet of 'dmesg' output below says that I have a
"non-ATA66 compliant cable". How does it know?

The cable in question is supposed to be ATA66 compliant. The full 'dmesg'
below shows the presence of a promise ATA100 controller - it is not attached
to anything. I am using the on-board IDE ports on this FIC AZ11
motherboard. Thanks.
