Does anyone know if there is a way to reset a firmware password from an EFI shell? I booted to a rEFIt disk and was poking around in it's shell but couldn't find anyway to reset the password. On PowerPC Macs you could do lots of stuff in the Open Firmware shell. Basically anyway to reset the PRAM, NVRAM, or firmware password without booting is what i'm looking for. I know the firmware password but i can't remove it in order to reset the PRAM because i'm locked out of booting up. This is a MacBook Air so i can't use the pull a stick of RAM out trick.
Any help would be greatly appreciated.
Edit: I ended up figuring this out. the rEFIt shell has a command called dmpstore which allows you the clear all or parts of the NVRAM.
