<p>Thanks. I successfully enable the needed display in Coreboot. And it can boot linux correctly, but booting windows fails.</p>
<p>Now my question is, is it supposed to boot windows, like Win 7?</p>

There used to be a priority list which display is preferably initia-<br>
lized. It was in a weird notation LFP (local flat panel) would be<br>
the eDP port and EFP2 (external flat panel 2) might be DDI2. Some-<br>
where you have to set that EFP2 is preferred, I suppose. (All what<br>
I remember from an Ivy Bridge VBT.)<br>
