HP 800 G1 AIO Can't Configure Integrated Graphics in Bios

[vinanator]

Hi, I am trying to enable integrated graphics for compute/decode purposes (not display output) alongside the dedicated radeon hd 7650a card. According to the maintenance and service guide for the machine the bios option "VGA Configuration" should allow you to do exactly that when a dedicated card is installed, but in my bios it is greyed out. I believe consequently under "Device Options" there is no "Integrated Video (enable/disable)" option. It's almost like the bios doesn't recognize the igpu (cpu is 4770s so it has one). I have tried reflashing the original v2.21 bios, and then updated it to the latest v2.70, still nothing. There is no bios password and every other option is available, so I do not believe it is a "rights" issue. Thanks in advance, any help is appreciated.

I think this is going to be a problem. The AMD mini board

uses quote "the output of the host mobile device."

I suspect your system, like many similar hp systems, cannot enable the intel graphics when the board is instlaled.

There is another problem.  I assume you wish to run OpenCL  The i7-4770s is a low power Haswell series  It is old and only supported OpenCL 1.1 and possibly 1.2.  The OpenCL drivers are installed with the graphics driver package.  I suspect that package will not install if the graphics is disabled which appears to be the case..  You can try the legacy SDK but I suspect the SDK will not see the graphics device on the CPU.   That was the case for my I7-6700  H81btc system with several NVidia cards.  The Intel graphics had to be enabled before the NEO driver enabled the OpenCL.  

If running linux you might ask over here as there is some success with Haswell and OpenCL

From what i can find online it should be possible, the official HP service manual even states it as an option in the bios: "Integrated Video (enable/disable). Use this option to disable the integrated video controller when another video controller is present in the system. Default is enabled." but on my system this option is missing, and it is definitely not enabled. I intend to use the integrated gpu for quicksync support in mac os. I think I might just have to remove the AMD card and see if that forces it to enable the igpu, and then go from there. Thank you for the response
