BSOD with AHCI on M1730 for Vista64

Thread Starter 
I downloaded all of the drivers for Vista64 from the Dell website before installing but even with doing a "Load driver" during installation and pointing it at the AHCI driver I would still BSOD on the first reboot. I was able to get Vista to install by setting the SATA drive to IDE but now want to switch it back to AHCI mode. I followed the regedit instructions that MS posted on this but I still get the 0x00000007B BSOD if I have the bios set to AHCI mode. Is there something else I can do?

Why bother with AHCI? All it really gives you is the ability to hotplug the drive...which of course you CAN'T DO with the system drive anyway. NCQ is a nice feature but your hard drive has to support it as well and I really don't know what the performance difference is with NCQ and without. If your hard drive doesn't support NCQ you're out nothing leaving it in Legacy mode.

NCQ performance really only benefits uses like in servers in data centers and stuff, on a notebook it is a moot point

The disk that is in the laptop supports NCQ. I did read somewhere else that Vista will use NCQ if it sees a disk that supports it even if the disk is in IDE mode. I have no idea how it would do that though.

Edit: The M1730 has flash memory to buffer from the drive that gets disabled if not running in AHCI.

I had the same problem on my M6300 more than a year ago, and all of this was posted on this web site, but it no longer seems to be here. I don't remember precisely how I fixed it, but it did involve editing the registry accoriding to the Microsoft instructions concerning AHCI and enabling AHCI in the BIOS. It was a real pain in the ass to get Vista x64 installed with AHCI. I do know that this registry edit was required prior to installing Vista x64 or else the installation would go into an infinite reboot loop with BSOD. A user name 'SoloApathy', I think was the one that helped me.
