Disable GPU via Clover or DSDT?

[InsaneCultist]

Hey all -

On one of my X58 towers (specs in signature), I am running a Radeon 6670 for graphics support under OS X. Recently, I have come to own a Radeon 6950, which I am using as a secondary card in this tower. However, due to the lack of drivers and issues with the 6950 under OS X, I cannot manage to get my system to boot up with the card installed.

I am wondering if it is possible to DISABLE the card via Clover or DSDT for OS X so that I can still use the 6670 in my first PCIe slot, but boot into Windows to take advantage of the 6950 when I want to. Otherwise, I may just sell the thing and grab myself something supported.

Thanks for any help.

try the following DSDT fix,

1. locate your graphics device in DSDT.
2. insert the following code:

Method (_STA, 0, NotSerialized)
{
    Return (Zero)
}

This might help.
