jucytec Posted March 24, 2011 Share Posted March 24, 2011 Is anyone working on getting the switchable graphics to load in Boot Camp? It'll be nice to run INTEL Drivers for most of the time when using MBP. Such a shame that Boot Camp drivers do not support or even show the Intel HD card under device list in Windows.

qreed Posted April 30, 2011 Share Posted April 30, 2011 Not sure if someone is working on it: the IGP is disabled by the BIOS emulator (that's why it doesn't shows up in the device list). The only way to enable it is to modify the BIOS (quite hard) or do a re-enable trick in the bootsector like this one (if there are any bytes left). It's probably easier to spam Apple.

Deefa Posted August 6, 2011 Share Posted August 6, 2011 How does the efi/bios emulation stop the Intel HD 3000 from being allocated resources? If you suspend/resume win7 on a 2011 15/17" MBP, the Intel HD 3000 device is found, drivers installed but the device cannot be initialised as there are not sufficient resources. The device does not persist after reboot. It would be nice to able to enable resource allocation for the Intel GPU, with a little MBR patch!, to be able to use its quicksync features (I'm not bothered about switching b/w the AMD & Intel GPU).

Deefa Posted August 10, 2011 Share Posted August 10, 2011 I'm pretty keen to investigate this - anyone know how to dump the efi bios emulator? code to disk so I can search for the code that's disabling the HD 3000. Link to comment Share on other sites More sharing options...
metatech Posted June 20, 2012 Share Posted June 20, 2012 Hi, The Intel integrated GPU on Core i3/5/7 can normally be enabled in BIOS mode with the following line in grub.cfg : setpci -d 8086:0044 54.b=0b You may need to customize to your CPU PCI ID, which can be obtained with "lspci" metatech Link to comment Share on other sites More sharing options...
