And please do not use the BIOS I will post until you have a flash programmer (CH341A and SOIC8 test clip cable in your hand) I say this because often with laptops users try changing these display options and end up with black/blank screen and cannot recover until they order flash programmer. So be ready in advanced

@Lost_N_BIOS I want to see "Primary Display Selection" menu in BIOS.

You need to be able to see all of those if you want to change any. Did you order flash programmer and test clip cable, or do you have already?

Please upload images in a zip of your advanced BIOS page/pages.

Please also check main BIOS page and see if you see ME FW version listed, if not download HWINFO64 and in the large window on left expand motherboard, then go to ME area and find the ME Firmware version and let me know what version it is (First digits only like 11.x or 10.x etc)

Yes, EZP2010 would be OK, if it has the SOIC8 test clip cable in that kit. Thanks for BIOS images, I will check it all and see if I can enable all of the above to be visible for you in the BIOS. I'll need your FPT dump first though, as outlined below.

Please download ME System Tools V9 from this page in section "C"
https://www.win-raid.com/t596f39-Intel-M...Tools.html

Inside you will find Flash Programming Tool folder, and inside that a Windows or Win/Win32 folder. Select that Win folder, hold shift and press right click, choose open command window here (Not power shell). Then in the command prompt window enter the following command and send me the created file >> FPTw.exe -bios -d biosreg.bin

I think also, you may need to change the first setting I mentioned above (default = Muxless), due to what I see on this page
http://leshcatlabs.net/forums/printthread.php?tid=55
Hybrid Graphics
•MUX-ed: Displays are only connected to the iGPU or dGPU.
•MUX-less: Displays are always connected to iGPU; the iGPU uses the display engine of the dGPU solely for rendering, not displaying. In theory, the two GPUs act as one.

I'll try to make all those visible for you so you can try a few things, but this is why you need programmer, some of these may leave blank screen and you'd have to recover or reflash blindly (you can, before this happens, make a DOS FPT flash autoexec and then learn.write down the steps to make it run, which keys you need to press when etc) Otherwise if you do not do that and learn the steps for blind recovery, some setting may leave you needing to recover via flash programmer.

I couldn't open the file with command window. There is no such an option as command. Only power shell exist. But i did dump my bios with dos fpt.(used bootable flash) I am going to attach it.

I noted all steps if I have blank screen first I will try reflash blindly. If it won't work my friend has EZP2010.

Sounds like Win10 issue! If you are stuck on Win10 and cannot easily get command prompt, here is some links that should help
https://www.windowscentral.com/how-add-c...ors-update
https://www.windowscentral.com/add-open-...windows-10
https://www.laptopmag.com/articles/open-...privileges

DOS will work just as good though, so we can flash from there too, if that's just as easy for you, or do the above.

I will work on this tonight for you. there is two ways to make things visible, so at first I will send you two BIOS to test with just a single setting made visible, then once you let me know which way works I will do the rest

On your blind reflash, you can test that now too, while you can see the screen, that way you confirm you can reflash without being able to see the screen.

OK, here is test, please let me know if you can see Advanced >> System Agent >> Internal Graphics
If not, more advanced unlock will be needed
http://s000.tinyupload.com/index.php?fil...3239520377

If you can see Internal graphics, but not the others above, let me know and I will enable them. This mod was only to make visible the main subsection they are in (SA) and attempt to make one setting visible for you if not already visible by enabling that section. If no System Agent section, then different mod method will be needed.
