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.
