I created my first DSDT file from Windows, using DSDTse for Win, while I still had AHCI disabled. Then after enabling AHCI, disabling the serial and parallel ports in the BIOS, plugging in and turning on all eSata drives I generated another DSDT.dsl from Windows. As I don't have Xcode installed, I can't diff them, but if you like I can upload both DSDT.dsl files (or attach them to a post) if they would be of any use to the pros ....
