Any way to load VESA instead of Leo/Snow Video drivers?
« on: August 31, 2009, 05:29:49 AM »
Hello.
Is there any way to make Chameleon ignore Leopard/SnowLeopard graphic drivers (ATI or NVIDIA) and load VESA?
I'm trying to boot Snow Leo retail with my HD4850.
I know there are a lot of solutions to make it recognize that VGA, but all of them involve an already installed system, where you have to change some kexts in /S/L/E. The problem is that I can't boot Snow Leo installation because even if I put the necessary kexts to /<installation_device>/Extra/Extensions, they won't be loaded because there are other kexts in Snow Leo installation itself.
I've managed to boot the installation by adding the -x argument. But I don't want to have to boot in safe mode just to install Snow Leopard.

In short: Snow Leo boots correctly if it loads with VESA drivers for my HD4850. I want to boot installation with VESA drivers and install the necessary kexts only after SnowLeo is already installed.

You could try removing your device ID from the kexts, or the kexts themselves from your installation media.

If it can't id your video card it should run in Vesa mode I guess.
