nForce 4, SATA Drive only runs at UDMA33?

[alan bryan]

Hi,

I've got a new machine and don't think I'm getting all
the speed out of it that I should be.  Any hints/ideas
for what I can do to make the most of my new hardware?

FreeBSD 5.4-Release
Shuttle SN25P
Nvidia NForce 4 with SATA 150
WD Raptor HD

I ran atacontrol and it reports:
# atacontrol list
ATA channel 0:
    Master:  ad0 <Maxtor 6Y160P0/YAR41BW0> ATA/ATAPI
revision 7
    Slave:  acd0 <SONY DVD RW DRU-510A/1.0c> ATA/ATAPI
revision 6
ATA channel 1:
    Master:      no device present
    Slave:       no device present
ATA channel 2:
    Master:      no device present
    Slave:       no device present
ATA channel 3:
    Master:  ad6 <WDC WD740GD-00FLA2/31.08F31> Serial
ATA v1.0
    Slave:       no device present
ATA channel 4:
    Master:      no device present
    Slave:       no device present
ATA channel 5:
    Master:      no device present
    Slave:       no device present
# atacontrol mode 3
Master = UDMA33
Slave  = BIOSPIO

It looks like the standard IDE port is being detected
as the nForce4 but the 
SATA controllers aren't - they just get labelled
"GENERIC".  Check it out 
below.
A verbose dmesg reports:

my new hardware?
