Can you enable AHCI in Windows 7 on a MacBook Air 11"?

i know people have enabled AHCI in MB Pro's. there's a bunch of information regarding that laptop. i've tried to follow those directions but AHCI just won't turn on. i'm wondering if the PCI IDE Controller just doesn't support AHCI or if i'm doing something wrong.

does anyone have any information regarding this matter?

thanks in advance.

MacBook Air 11" 1.6Ghz 4GB Ram 128GB SSD, Mac OS X (10.6.4), Windows 7 Ultimate 64

Actually I'd say that Macs are a big enough chunk of hardware market, and high priced and quality one - and if Windows can not run on them natively - it is Microsoft decision and their problem. Microsoft established itself as provider of "run-on-anything-Intel" OS, Apple in this case is just standart-compliant (sic!) hardware maker.

If you think about MS supporting really outdated BIOS computers, it is just miracle that EFI 1.1 threated as out of support as legacy. It is clearly political decision from MS. Actually BootCamp is huge step from Apple - cos they do not owe us non-Apple operating system support at all.


About TRIM and Mac OS... Trim got mainstream may be year ago, and yes, MacOS I think was last big OS adopted it. But why mutually exclusive? Yes, Apple loves their (pricey) hardware, it is well known, but this is their business ) Only-Apple trim is real benefitfor Apple SSDs, it is clearly the only cause for it. From other side - if apple will enable trim for anything SSD, there'll be a huge wave of crying babies with SF drives - and Apple anyway will be "bad implemented trim in Apple drivers cause stutter". This is loss-loss situation for them. So they lock it to tested only drives - A-SSD - and even got some profit. Nice move from my POW.
