A somewhat more concise discussion of Windows 7 and GPT can be found here: http://msdn.microsoft.com/en-us/library/windows/hardware/gg463525.aspx Information on ACHI is available at: http://www.everything-microsoft.com/2010/05/25/how-to-enable-ahci-in-windows-7/ http://www.ithinkdiff.com/how-to-enable-ahci-in-windows-7-rc-after-installation/ -- Jerry ♔ Disclaimer: off-list followups get on-list replies or get ignored.
