It won't work because there is NO DSDT Table in the BIOS to edit. It may be Possible to manually Add one but I really have no idea if it is or not. I have never worked with MACs and have never attempted to add a DSDT table to any BIOS. You will have to Search and find out if anyone is doing that or not.
Sorry, I have NEVER Flashed an Intel board. Search the saite and see if anyone else posted the proper tool and switches to use.
