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?
Thanks,
Wayne

my decision on the kernel source code. It seems to indicate the Intel
ICH7 is AHCI compatible:
We (yesterday) found out that our board (a Supermicro PDSMI+, ICH7 as
well) needs the proper BIOS setting in order for it to appear as a
AHCI capable controller.
Precisely, we found if we enabled "SATA Enhanced Mode", then enabled
"AHCI" in the BIOS, the chipset identifies itself as a 0x27c1 device
rather than a 0x27c0 device.
This is probably exactly the issue you ran into. Try your BIOS settings.

Leon Woestenberg.
