Is it possible to get AHCI working on this controller:
atapci1@pci0:0:31:2: class=0x01018f card=0x72101462 chip=0x27c08086
rev=0x01 hdr=0x00
vendor = 'Intel Corporation'
device = '82801GB/GR/GH (ICH7 Family) Serial ATA Storage
Controller'
class = mass storage
subclass = ATA
bar [10] = type I/O Port, range 32, base 0xe880, size 8, enabled
bar [14] = type I/O Port, range 32, base 0xe800, size 4, enabled
bar [18] = type I/O Port, range 32, base 0xe480, size 8, enabled
bar [1c] = type I/O Port, range 32, base 0xe400, size 4, enabled
bar [20] = type I/O Port, range 32, base 0xe080, size 16, enabled
cap 01[70] = powerspec 2 supports D0 D3 current D0
BIOS show that AHCI 1.0 supported.
