nVidia chipsets?

Is this the same nFORCE 4 used on the socket 939 boards?

I have a 939 with "nforce 4 ultra".  (ultra means it supports
SATA's NCQ queueing)  I'm running FreeBSD 6.0 on it.

The nforce Ethernet works, but I've only used it for a few minutes,
and didn't stress it at all.  I haven't tried sound with FreeBSD.

PATA and SATA work.  It can read from 4 SATA disks at once as fast as the
data comes off the platters (65-70MB/s at the fast end of the platters).
I'm running soft updates and have the disks' write cache in write-through
mode to avoid scrambled filesystems.  In write-through mode I get about
6-7 MB/s.

If anyone knows how to turn on SATA NCQ, please let me know.

But there is a problem.  Writing to one drive slows down writes to
an unrelated drive.  (I'm not using any form of RAID.)  See the
"processes not getting fair share of available disk I/O" thread
in -questions for more info on this problem.  At this point I don't
know if this problem has anything to do with the nforce chip or not.

My board has an onboard ATI chip.  Xorg seems happy with it,
but ATI doesn't support sync-on-green, so it is useless with
my monitor.

The nforce USB works, although I haven't stressed it.
