Vista Reliability Pack Two

[nekrosoft13]

I can confirm, at least from the 4 machines that I have at home, that this is indeed AHCI-related. My main rig has an Areca 1210 raid card, so installing the patch worked perfectly. My second rig was set to AHCI and it would not let me boot at all, not safe mode, not last known good config, nothing. I had to use the Vista disk and repair. My 3rd rig was set to AHCI mode and same. So, in the bios I switched it to IDE mode and bam, loaded right into Vista without issue. My 4th, a latop, had no issues.

This is an incompatability issue with AHCI.

All three rigs have P35-based motherboards. Just a data point.

its possible since the patch updates all IDE controller drivers (also used with sata)

I was using the Same Intel i975x/i965/P35/Q35/G33 chipset drivers and loaded iastor32.inf during windows setup for Raid/AHCI mode as I'm using a Raid0 array on my ICH7R controller. So a good guess would be anybody using AHCI/Raid drivers from Intel on their motherboards with Intel chipsets will encounter this dilemma. Best advice from me is to simply not install any intel chipset drivers unless its in Windows Install, as loading the initial ones through the setup don't seem to cause any problems, rather when the chipset drivers are installed (infinst_autol.exe) ethrough windows after installation.
