I'm loading ahci from loader.conf. There are several types of ICH7. Most of them doesn't support AHCI mode. Rare exceptions are ICH7R and ICH7M AFAIR. G41 is low-end desktop chipset, which uses low-end ICH7 SB, so usually there is no luck. > atapci1@pci0:0:31:2: class=0x01018f card=0x81791043 chip=0x27c08086 rev=0x01 hdr=0x00 > vendor = 'Intel Corporation' > device = '82801GB/GR/GH (ICH7 Family) Serial ATA Storage Controller' > class = mass storage > subclass = ATA To make ahci(4) attach, you should have there subclass SATA or RAID. It may depend on BIOS settings. -- Alexander Motin
