Hi guys, i've got a samsung rc730 with intel hd/nvidia 540m optimus on. I start gpu z and it recognizes the card and shows stats, recognizes BIOS version and everything else. Problems come when i try to save BIOS: I hear two beeps from motherboard and gpu z says "BIOS reading not supported on this device". I've already searched the forum but i wasn't able to find a solution. Can you help me please?
