I'm installing Win 7 on a Mac Pro 3,1 with Bootcamp and am following the directions given on another MacRumors thread to allow the use of ahci drivers. Part of the process is to run a script file - "ahci-1.sh" - that will modify my Win 7 MBR to allow ahci drivers to load. But for the life of me, I cannot get the "ahci-1.sh" script file to actually execute. As per instructions, when I type "sudo" followed by a space and then drag "ahci-1.sh" into the terminal window, all that happens is that the path to ahci-1.sh is printed following sudo and the space. But the script does not run. I don't know what I'm doing wrong. Are there other ways to make a script file execute from the command line?
