Re: AHCI support on Intel chipsets (confusion?)
Leon, Thanks for the reply. I have enabled SATA Enhanced mode, but still did not see any mention of AHCI in my dmesg output. I also did not find a setting for AHCI in the BIOS. My board is a Gigabyte: http://www.gigabyte.com.tw/Products/Motherboard/Products_Spec.aspx?ProductID=2304 I was about to email GigaByte and ask them about AHCI, but I decided to do a search first. That is when I found the Intel page that says ICH7 does not support AHCI. If that is so, then I need a different motherboard. Can you confirm that ICH7 does not support AHCI?

I just checked your motherboard: http://www.supermicro.com/products/motherboard/Xeon3000/3000/PDSMi+.cfm It uses an ICH7R, and according to the Intel page that one *DOES* supports AHCI.
