Consider "IDE" to mean "Compatibility mode". I just RTFM for your manual, it tells that if you want to use NCQ or hot-plugging you must enable AHCI in BIOS. I have a Gigabyte motherboard and it's the same way. If I use "IDE" mode, kernel must use a different driver (it's still not really IDE. When I use AHCI, it uses the ahci driver in kernel and all features 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. ;)
