hello, did anyone try to flash stock bios? i try to flash my backup .bin file but i got this error. PDR Region does not exist. GBE Region does not exist. Error 28: Protected Range Registers are currently set by BIOS preventing flash access. Please contact the targetsystem BIOS vendor for an option to disable Protected Range Registers Solution: After enabling back bios flash option in current bios, i flashed stock bin file without problem.

Before, I installed hackintosh to several machines. But I fail on y500. I tried with my own patched DSDT, with combinations of boot flags, clover - chamelon, w/w-o ultrabay. Removed Intel - Nvidia etc kexts, patched mach_kernel etc etc. Nothing works. Best way is installing it to vmware.

in y510p, when you remove sli card, you can use intel hd graphics. But in lenovo y500 you cant. So install fails. Laptop shut downs instantly.

flash bios with white list removal, uninstall your current driver from device manager, install your new wifi card, boot to windows and install wifi driver.

no, you install bios to your motherboards rom. not hard drive.

you should enable legacy boot support in bios too if you booting non uefi media.
