According to the SATA/libata status page:
http://linux.yyz.us/sata/sata-status.html#nvidia
I guess they were talking about the MCP-03, instead of the
newer MCP-04? In any case, I'm not getting NCQ support on my
nForce4 serieschipsets under Windows. I guess some just
don't include it?

ATA = SATA
You can have NCQ on parallel ATA too.
It's just a physical/datalink layer difference.

Between the drive and [software] host, individually. Then
you use [software] host AHCI to control and schedule up to 32
drives.
My point is that it's still not a hardware-based host
adapter. It's only the end-device component, with a software
host.

Yeah, it seems the regular nForce 4 and at least the nForce
410 (not sure about the 430) don't have it.

I stand corrected then.
As I said, I heard 2nd hand.
