Last i know is that Intel doesn't provide an AHCI driver for the non-RAID version. (For whatever political reason). That is even documented in the german "c't", they even had an articel about "patching in the Device-IDs" so the RAID-AHCI driver accepts the non-RAID AHCI chipsets. And i can second that, when i configure my @home MB (ASUS P5B = non-RAID) to AHCI neither XP nor Vista work. @work i tried to install Vista on an AHCI-configured machine and aborted that "expriment" after about 2 hours. In IDE-mode it took Vista about 3 Minutes to reach the point where i aborted the AHCI experiment. So i must say: My milage varies. Bis denn -- Real Programmers consider "what you see is what you get" to be just as bad a concept in Text Editors as it is in women. No, the Real Programmer wants a "you asked for it, you got it" text editor -- complicated, cryptic, powerful, unforgiving, dangerous.
