Hey guys new to the site here but not exactly new to bios mods. Im looking forward to trying out this whitelist removal method in hopes that I can also use the Intel Wireless-AC 7260 (cant wait to hear WireMesh tell us if all works well). However I was curious about one thing. I have the Lenovo y510p and was just looking to do the whitelist, but I see there are steps for flashing something related to the send 750M in the ultra bay. Is this step required? Im thinking its not as it seems like this is a seperate flash to allow for modifying the clocks or others specs of the cards? If im wrong would you mind going into a little detail as to if the Ultrabay flash is required and what it does? Thanks!
