I need to install an external GPU on my HP Pavilion Dv6-6c16nr Laptop, but there are no options in the BIOS Setup to disable the Internal GPU, I can't even modify the Memory Allocation for the iGPU...is there a bios mod out there that will help me with this problem? There are only few options available in the BIOS Setup, I can't even modify/change some of them...help please!!! Bios Version F.1c
