For example, using configuration 0x01660000 (96 MB, 3 pipes, 4 ports), set the Graphics Memory Size to 96 MB to match. If they don’t match, the driver may crash (kernel panic at gen7_memory.cpp:721), or the display may be corrupted. I did not test the HDMI port.Īlso, the graphics memory size for the configuration must match the setting in BIOS. The VGA port is not enabled for any of the configurations. For configurations with two or more ports, DVI was available. On my GA-Z77M-D3H, for configurations with one port, the enabled port is not the DVI port. Configurations with just one port should probably be avoided because it’s probably not the port you’re looking for. Configurations with zero ports should be avoided (no output?). Setting AAPL,ig-platform-id to any of the 12 values will load the HD4000 driver, but there are some other constraints.įirst, the setting affects which ports are enabled. The value of AAPL,ig-platform-id selects which graphics configuration the driver will use (er, blindly assume).
The AAPL,ig-platform-id property is a 32-bit number that must be one of the values listed in the following table. Of course, on anything other than Apple hardware, this property wouldn’t exist, and would need to be added.
