Guilmette >Release: FreeBSD 8.2-RELEASE amd64 >Organization: entropy >Environment: 8.2-RELEASE GENERIC amd64 Motherboard: Gigabyte GA-M55plus-S3G (chipset Nvidia Gforce 6100 + Nvidia nForce 430) Drive: Seagate ST3500320AS >Description: I just recently installed 8.2-RELEASE/amd64 on this system and looking at dmesg output I noticed: ad4: 476940MB 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.

This chip does not support AHCI." http://forums.freebsd.org/archive/index.php/t-22186.html http://www.wonkity.com/~wblock/docs/html/ahci.html >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. >Fix: Beats me! I just work here (and I don't do drivers). >Release-Note: >Audit-Trail: >Unformatted:
