VGA but not DVI (Nvidia 210)

[yoyoman]

When booting, I can see Nvidia 210 flash on the screen fast, but later I see the "Probes failed" error. I'm not sure why ....

Anyhow, with DVI, I get a black screen which renders the computer useless. However, as I read elsewhere, someone said that sometimes VGA works, and in my case it does. Using VGA, I have all resolutions available and I have QE/CI.

How can I get DVI to work?

You might try DSDT edits for that card- I got my 9400GT working with DVI/VGA (but not s-video) in 10.6.3 with the help of this code. It can probably be modified with NVCAP, etc... to suit yours. Just download IORegistryExplorer and find your Graphics section.

... I got my 9400GT working with DVI/VGA (but not s-video) in 10.6.3 with the help of this code.

                                "@2,#adress-cells",
                                Buffer (0x0B)

Tony, can you explain the purpose/effect of these entries in that code you posted?

You'd have to ask FatShenanigans- she made the edits in addition to the ones I did from my guide.
