UEFI or old style EFI on new MBP's (2011)
The reason why I am asking is because I would like to see if it would be possible to dual-boot Windows with AHCI support. When using Boot Camp, Apple configures the BC partition to run in proprietary BIOS mode as well as shuts off AHCI support. Windows Vista supports EFI boot starting with SP1 as does Windows 7; however, it needs UEFI 2.x. Earlier MBP models only have EFI 1.x which do not allow this. There is a way to hack the boot sector to enable AHCI, but I would not rather go that route as it introduces some unpleasant side effects.
If Apple upgraded these new MBP's to UEFI 2.x, perhaps native AHCI support would finally be possible. I know most of the Sandy Bridge motherboards out there support UEFI now. Wonder if Apple followed the trend.
