AHCI + SIS968
atapci1@pci0:0:5:0: class=0x01018f card=0x08021558 chip=0x11831039 rev=0x03 hdr=0x00
vendor = 'Silicon Integrated Systems (SiS)'
device = '?SATA (?SIS966/968 )'
class = mass storage
subclass = ATA
В ядро:
device ahci
device ada
После чего имеем:
ahci0@pci0:0:5:0: class=0x010601 card=0x08021558 chip=0x11851039 rev=0x03 hdr=0x00
vendor = 'Silicon Integrated Systems (SiS)'
device = 'AHCI Controller (SIS968)'
class = mass storage
subclass = SATA
И не забываем поправаить /etc/fstab, и включить в BIOS AHCI.
