I'm having some trouble enabling this mode on my Win8 machine; regardless of what I try with my setup I'm still missing the GPU device from my HD4000 device.
My setup is Win8 x64, I have an Ivy Bridge CPU with HD4000 graphics and an AMD 7970 GPU. My motherboard is a Z77 with the Lucidlogix chip on it.
I've tried uninstalling all the drivers for both GPUs and reinstalling them, starting with the latest intel driver. Even without the AMD driver installed without a cable connected to the onboard display adapter the GPU device doesn't show up.
If I enable the Lucidlogix iGPU setting in the BIOS the device shows up in the device manager as connected but the OpenCL device doesn't show up. If I disable the setting in the bios then windows reports the device is not connected to the computer (and the OpenCL device doesn't show up).
If I look at the driver details in device manager then it shows a driver date of '19/03/2013' and version '22.214.171.12471' so I'm pretty sure I'm running the correct driver.
So, does anyone have any ideas as to how I might be able to get this working?
For testing and dev purposes I can always just connect the device to a monitor but this doesn't feel like a good long term solution...
