Legacy/Native IDE mode is designed for compatibility with some old OS without AHCI driver but looses SATAII/AHCI features such as NCQ. This patch will make SB600 SATA run in AHCI mode even if it was set as IDE mode by system BIOS. is this really the right thing? You're overriding a user chosen configuration here.... while that might be justifiable.. it's probably a good idea to at least provide a safety-valve for this one. The user might have made that selection very deliberately. -- if you want to mail me at work (you don't), use arjan (at) linux.intel.com Test the interaction between Linux and your BIOS via http://www.linuxfirmwarekit.org - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
