Gateway DX4870 mod request

[nyonako]

Hi there, looking to unlock any hidden menu items/options for the following bios:
Gateway DX4870 / Acer Aspire M1935 (same thing)
Latest bios is here: http://global-download.gateway.com/GDFiles/BIOS/BIOS/BIOS_Gateway_P01.A2_A_A.zip?acerid=635040993388166881&Step1=DESKTOP&Step2=DX%20SERIES&Step3=DX4870&OS=ALL&LC=en&BC=GATEWAY&SC=PA_6G

By default, Kepler based graphics cards do not work on this bios, the machine was sold running windows 7, there was a version running windows 8 (same model number) that uses a different bios, disabling secure boot and setting launch CSM to "always" allows kepler based cards to run on that one, but no such options exist on this windows 7 version.

This is the bios for the Windows 8 version - http://global-download.gateway.com/GDFiles/BIOS/BIOS/BIOS_Gateway_P11.B1_A_A.zip?acerid=635321007306718972&Step1=DESKTOP&Step2=DX%20SERIES&Step3=DX4870&OS=ALL&LC=en&BC=GATEWAY&SC=PA_6G

I have tried flashing the windows 8 bios to this machine and it fails unfortunately, gives an invalid checksum error!

Any help would be much appreciated.
