Just upload the one you want done and I'll do it now. I don't mind at all. There's no sense in risking your MB, if you can upload the existing BIOS to be modified.
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.
