Thanks for confirming your board use the same trick to get VGA out of a eDP port, only the eDP build might work for onboard VGA yet(Linux OS only or Windows with Intel Proprietary Driver) bootscreen is DVI / HDMI or dGPU.

Can someone still confirm `xrandr` output with a iGPU?

Thanks @walterav so I tried all of those roms by external flash.
so on all of them I get fans turning and light coming into the gpu. (I do not have vga so have to use the nvidia gpu)
Then it all turns off
No sound, no video, however the usb ports flash on and off.
If you are running off @davids rom you know he has a different bios chip to mine? See page 1.
here is my original bios.

Will spin up new ROMs later with your full donor rom. Is this a original OEM rom dump without any hacks/mods/patches me cleaner so yes which version is it?

Does the system turn off or does it keeps restarting(loop)? Turn on is it like 2 seconds, or more like 10 seconds?

Do you have a serial port null modem cable so you may read the coreboot debug bootlog from serial? Have you tried my CMOS reset jumper method described a couple of pages back on the forum?

[james2]

thanks, it just turns off does not restart. That should be the original oem, I can upload the working me_cleaned one if thats easier? then it wont turn back on again without turning off the mains.
no I have no turns on for like 10 seconds. no I must have missed that, CMOS jumper method.

Good to know its original what version?

What CPU do you use and how is your RAM config 2 identical DIMMs / mixed? Swapped RAM DIMMS or use one at the time in 1 slot?

2 identical 16gb dimms, cpu is a i7700k kaby lake. btw I tried to splice your bios region and got a little further as in fans go and stays for about 30secs but then shuts down and wont come back.

[james2]

This is my stock that has been ME cleaned.

So I don't know where you both are at with this build, I have pretty much given up building on top of the h110m-dvs rev2.0 coreboot and am now building coreboot from generic intel / kabylake from scratch. There were just to many variables on the rev2.0 that are different to the rev3.0.

One think i discover when i was testing before is this:

If you provide different ifd descriptor than what is on original rom coreboot will build but it will not boot most likely modification of FMAP on coreboot will be needed.

So guys for testing use original ifd first from original rom.
