I seem to have the same problem as darkwill... I have a m17xr4 with A11 which i've been trying to hard enable the 7970m on (some work software keeps defaulting to the 4000 even when I set it up to use the 7970m on max performance) so I need to wind the bios back to this version, to install a hacked bios over the top of, to tweak.

I follow the instructions, and when I turn on whilst holding Home the PC resets once or twice and then just beeps, for ages. Then eventually I manually turn it on and it's still A11.

So I guess A11 isn't downgradeable?

To switch on 7970 ONLY (without HD4000) you have to press Fn+F7, after get prompt to reboot and you can see in Device manager ATI 7970 only!Not necessary to install modified BIOS for desactivation HD 4000, this is the main difference between Alienwere and other brands based on Clevo barebone.
