I just recently installed 8.2-RELEASE/amd64 on this system and looking
	at dmesg output I noticed:

	ad4: 476940MB <Seagate ST3500320AS SD1A> at ata2-master UDMA100 SATA 1.5Gb/s

	I researched the drive (ST3500320AS) and found that it supports SATA
	@ 3.0Gb/s.  The motherboard allegedly does also.  But as you can see,
	I'm only getting 1.5Gb/s upon booting the system.

	I did some googling around to try to find the cause of the problem,
	and I found suggestions to enable AHCI in the BIOS, but apparently I
	can't, in part because there is no such BIOS option, and also because,
	apparently, the Nvidia nForce 430 doesn't actually support AHCI.

	But the nForce 430 _does_ allegedly support SATA 3.0Gb/s... just not
	via AHCI.  So, you know, I'd like to know if there's a way for me to
	enable the 3.0Gb/s support on this board.  So far I haven't found any
	way to do that.

	Some potentially relevant links:

	  "The MCP61 is nForce 430, isn't it? This chip does not support AHCI."

Fix: 

Beats me!  I just work here (and I don't do drivers).
How-To-Repeat: 	I would imagine that just installing and booting 8.2-RELEASE/amd64 on
	any motherboard with the Nvidia nForce 430 southbridge will exhibit
	the problem.
