You're welcome, can't wait to hear how it goes!

VX full dump to your system would not work for many reasons, so I'd expect to hear that

@Lost_N_BIOS

While we are at it.
There is something else about this laptop I can’t figure out. When I put it in raid mode, I don’t get the dialog for the shortcut keys to get into the raid bios. So I can’t setup a raid array. Any ideas? Since I have to desolder and resolder my spi chip, we might tackle this in one step. (So I don’t need to torture that ic too much anymore)

Get SOIC8 test clip, they cost $3

BIOS contains both legacy and UEFI RST modules, so booting mode shouldn't matter there. OROM UI and BANNER is enabled and OROM UI Delay is set to 2 seconds, so you should have at least 2 seconds.
Maybe graphics is not displayed quick enough for you to see it, did you try blindly smashing CTRL+I all through startup. Do you see Asus logo? Is this Win10 system? Fast boot is disabled, but I do see Quiet boot enabled, so this may be cause. Can you see Quiet Boot option at Boot page of BIOS? If yes, disable and try again.

@Lost_N_BIOS bad news.
both give no image internal and external.

al least no post. didn't try to boot.

Try booting into windows too, so we know if that fails as well. Try UEFI mode if possible, with both

I'm on the "as is" swapped right now and I don't get anything after booting.
I don't know what the default mode for the bios is. I can't change it, since I don't see anything. :(

This was mine with the vbios injected. This one gave me external image. (took that dump before flashing your modified ones)

I'm reading trough a thread of osx (hackingtosh) issues with kepler cards. The g75vw is in there as well. It seems like they have to force the outputs trough dsdt or vbios.
Seems like the vbios has some kind of table with the different outputs in it. I don't know if we can fuse that of the original 660m with that of the 670mx.
This was the path I suspected.

the discussion about it: https://www.tonymacx86.com/threads/asus-...gtx660m.131887/
They had issues to get the internal display working (even on the gtx660m). somehow the igp is disabled. that's also mentioned there. and confirms what I see when booting windows.

edit:

update, @Lost_N_BIOS it's not the lvds I'm using but the EDP port.

found a schematic of the board:



using the upper port.
The one underneath it is lvds:

That's something I seem to know in my first post. But I seem to have been mistaken into believing it was lvds along the way.
I should consider starting smoking again I guess

I can edit the vBIOS (legacy) or GOP (UEFI) on the Intel side, this usually has all graphics routed through it and out to the panels.
And yes, in there is lots of panel settings and options, that's what I was originally thinking about doing for you when I jumped in there, but then realized leaving those as-is should be the perfect/correct settings for your system, since that's setup for this system by default.
But, maybe something in there, once the new NVIDIA BIOS is used, needs changed in regards to this. And there is why I initially asked if they ever sold this model with that card, then we could compare.
If I compare vBIOS/GOP for the other system now vs yours, anything different I see I wouldn't be able to tell if it's due to needing this change for the other card, or if it's different just because it's for the other main system which would obviously need different settings than yours (there is literally 100's of settings you can change)
And yes, in there is 20+ panel options, all with sub-settings and submenus etc. in the main BIOS itself too, there is hidden options for panel settings and other related settings. But as I mentioned above, all this is/should be currently already set to 100% correct setting for your system/panel/outputs etc.
But, maybe there is some setting that needs to be different for that card vs your original.

IGP can be enabled/disabled at hidden BIOS settings, I can make these options visible for you if you want to tinker?

We can try. If it might be wired trough the igp, we could try to get optimus working.
But then I need at least the igp working on the internal panel. I probably have the harest option, the 50-pin 4-lane edp for the 120Hz 3d panel. (got this machine second hand, so it was not purposely chosen).

I see Internal Graphics default is not disabled, as expected, so all graphics is routed through here like I mentioned. BIOS setting for Active LFP is Internal LVDS too. Remove the Nvidia card, do you see graphics output then, on any port?
All that you can see at Chipset >> SA >> Graphics Config. Since you already know how to edit/mod BIOS, did you enable chipset for your BIOS or not so you can see/edit on the fly in BIOS (I didn't check)?
Once I have more time tomorrow, I will look at the vBIOS and GOP settings and see what's set, and I think I can send you a textual output of all those settings too so you can see.

I am not talking about NVIDIA vBIOS, I'm talking about the vBIOS/GOP at Intel side that all graphics is routed through out to the displays.
All that is done with Intel BMP, we have a thread here about this, search for BMP. In there, in both vBIOS (Legacy mode) and GOP (UEFI mode) you will find 100's of settings for the panels, graphic output settings etc.
That's what I would send you text output from, this is what pushes everything out to all displays, and why in 99.9% of laptops you cannot disable internal graphics or you get black screen (no display output)

When I mentioned settings and their current defaults above, I was looking at your BIOS (and the default applied settings)

What CPU are you using, Sandy or Ivy?

Thanks. Here is a few example images of the GOP module opened in Intel BMP, and text output (.sff open in notepad) of all settings
http://s000.tinyupload.com/index.php?fil...591318139846653

Let me know if anything catches your eye on the images that needs changed maybe, or in the text and I'll find that setting and show you in image so you can also see the help/info for that setting

LFP = Local Flat Panel. That is what is set by default for your system, which works as originally configured. If it was incorrect, then it wouldn't work. There is 100's of settings, so the few example areas I showed you may not be what is used, you'd have to dig around and check it all.
+ BIOS controls some of this too at the BIOS settings level - which you can see in AMIBCP @ >> Chipset >> Graphics Configuration >> Settings (And submenu there for LCD) << Here, it's set to 18bit LFP >> Int-LVDS as optimal default. There is EDP A/D as optional choices, but both failsafe/optimal has Int-LVDS set

You're welcome! Sorry I don't have same system and card, or I could sort this out for you while you waited and try 1000 things at once without worry of bricked BIOS
