Original Question:
If anyone has removed the CFG lock and DVMT please let me know the addresses to call in GRUB. Im on the latest bios firmware 1.22. Ive been stuck trying to extract the dell bios update file with Dell PFS extractor, but it never works. I know people have done it on this system before, but nobody though to share the necessary GRUB commands.
