Consider "IDE" to mean "Compatibility mode". |

I just RTFM for your manual, it tells that if you want to use NCQ or |
14 |
hot-plugging you must enable AHCI in BIOS. |

I have a Gigabyte motherboard and it's the same way. If I use "IDE" |
17 |
mode, kernel must use a different driver (it's still not really IDE. |
18 |
When I use AHCI, it uses the ahci driver in kernel and all features |
19 |
and full speed are available. |

I think it's a bad name, just like "Keyboard: DOS/USB" setting, when |

"DOS" really means "PS/2 Emulation from BIOS" or whatever. |

So, use AHCI, be happy. ;) |
