Enabling this knob exposes an older interface to the OS over PCI. It was
required to install Windows XP without workarounds, because Windows XP
lacked AHCI drivers on the install disks.

Thank Andriy,
it appears my motherboard had a "IDE/SATA" compatibility mode which was
enabled by default and i had no idea what the option meant but once i
turned it off everything is showing up as AHCI.
Thanks for your suggestion!

I am having a strange issue where I have 6 drives attached to my
motherboard and 4 of them are coming up as SATA 2.x and the others are
coming up in a strange downgraded mode. The first 4 disks are always
shown
as being normal and ada4/5 always have the strange configuration. I know
the motherboard chipset is good and supports 7 drives of SATA 2/3 in any
combination so I'm perplexed as to what the issue is.
Why are drives 4 and 5 listed as being on bus ata0 and ata1 instead of
ahcich4 and 5?
Check your BIOS settings. Sometimes they have a separate IDE/AHCI knob
for the
last two channels.
