also I downloaded Intel ICH7 Data sheet which contains all pci configuration registers defines. thx for pointing out this. also i saw that ahci_host_init() will set low 4 bits to 0xF anyway for intel chip, and high 4 bits are RO. so the patch set 0xf or 0xFF make no sense here. so what can i do now? thx!
