Anyone have a functioning setup live at the moment for a test?

I don't know what you want to test, but both the rig from the linked thread and one with a modded Tillamook on a MVP3 mb with cache are running here.

Was curious about the response from the chip when intel bf2 was pulled high. Changing bf0, bf1.

From what I recall, intel bf2 basically defaults to pull down when floating.

And when bf2 is pulled down bf0,1 provide 133-233 mhz options.

But when intel bf2 is pulled high the chip always is at 266 no matter what bf0,1 are set to.

If someone can verify that. Not with my setup atm.
