It is not absolutely > necessary but it is better than without it, IMHO. :-) As I have told, with or without this patch I am any way receiving 4 AHCI channels + 2 PATA + 2 legacy SATA if IDE mode set in BIOS. If I enable AHCI mode in BIOS I am receiving 6 AHCI + 2 PATA channels. Looks like Dennis has the same. So 1) I don't see any effect of this hack on my system, at least with HEAD (is it working?), and 2) if we are doing all this magic and force AHCI mode for second controller, IMHO it would be reasonable to enable real AHCI mode to get all 6 SATA channels there. -- Alexander Motin
