DSDT for 9400GT 1GB

[xwin78]

I was able to get my 8800GT working w/ DSDT, now I have to get to work on this one. Where do I start---previously I just found the override and copied it to the proper location.

Thanks in advance

Personally, I don't think it's necessary to use DSDT for video. Chameleon RC4 works fine with 'GraphicsEnabled' option turned on. That's all I use now.

I need DSDT because I would like to try and use the s-video out--no luck so far w/ EFI strings

thanks

Should the VRAM not be:

                            "VRAM,totalsize", 
                            Buffer (0x04)
                            {
                                0x00, 0x00, 0x00, 0x40
                            },
