Hello.
I have a little question about the popular nForce4-SLI chipset for the 
Socket 939 platform. The onboard SATA controller of the nForce4-SLI 
chipset claims to be NCQ (or SATA II) capable, but nVidia implemented 
this feature in a not-AHCI-standardised way, but as an own solution. My 
question is: Is the FBSD 6.X driver for the nForce4-SLI chipset capable 
of using NCQ (as I know, the driver has to enable NCQ and it's not done 
automatically by the harddrive-controller interaction).

Thanks in advance,
Oliver
