Can anyone tell me if Windows 7 64-bit now has AHCI (SATA chipset) support set to enabled by default

I am going to be building a new Desktop PC. I have an SSD which I intend to use as a boot drive. SSDs (I'm told) must have the SATA Chipset set to AHCI in the BIOS. However, I'm also told that Windows does not by default support AHCI, and that the registry has to be edited to make it so.


Can anyone confirm that this is still the case. I would prefer if Microsoft had made this support enabled by default.

You can install with the BIOS set to AHCI. If there are no AHCI drivers for your motherboard chipset in the installation disk you will have to supply them. Any medium will do: floppy, DVD/CD or USB stick.


Check your motherboard manufacturer's site. The RAID or AHCI installation drivers - a separate, smaller set than the motherboard chipset drivers - should be available for download if they are needed.
