I have recently tuned my Mac Pro for dropping the legacy mode on the HD and ODD drives because I wanted to use a Blu-Ray drive under Vista Business 64-Bit. It now runs all drives in AHCI mode and shows much faster HD performance. I checked my unibody MBP and found it runs both SATA drives (HD and super drive) in Windows in legacy IDE mode. The MBP has a NVIDIA chipset which uses an MCP97 controller which is supporting AHCI version 1.2 according to my profiler under OS X 10.5.7. I would like to set this controller to AHCI in Windows as well. Unfortunately I am only familiar with the Intel drivers for AHCI drive management for the Mac Pro 5000 chipsets. I was wondering if one of the users here managed to ome across NVIDIA equivalents for running the SATA drives in AHCI mode? Search did not yield any results via Google or MacRumors internal search.
