Hello.
I have a little question about the popular nForce4-SLI chipset for the
Socket 939 platform. The onboard SATA controller of the nForce4-SLI
chipset claims to be NCQ (or SATA II) capable, but nVidia implemented
this feature in a not-AHCI-standardised way, but as an own solution.
My question is: Is the FBSD 6.X driver for the nForce4-SLI chipset
capable of using NCQ (as I know, the driver has to enable NCQ and it's
not done automatically by the harddrive-controller interaction).
Thanks in advance,
Oliver

Regaurdless of what the motherboard manufacturer says a SilI3114 SATA
controller is SATA spec 1.0.
Yes , that is exactly what I got from http://www.siliconimage.com/.
Every report I read about ASUS A8N-SLI Deluxe/Premium gave the same
technical specs: the second RAID5-capable SATA chip (SilI3114) is
attached to the 32Bit bus (*NOT* PCIe). Also, there is *NO* 64Bit bus on
any of the mentioned mainboards!
And, by the way, the nForce4-SLI MCP is capable of NCQ, but the
capability is *NOT* AHCI conform, so it seemes to me that we need a
special treatment using this add on - but we all know how restricted
nVidia is offering internal details about their chipset to open source
projects like FreeBSD.
This is what I found out searching the net, some articles and watching
this list.
