@Lost_N_BIOS Thanks for helping the folks here out! Not to rush you at all but just a quick reminder on the guide :) I know you're still prettying it up. It's just that with a proper (complete) tutorial/guide, others like myself can help the folks here out and take some of the workload off you guys.

@geekasm I didn't take any pics/screenshots but the gist of it is that you have to go to Chipset 2 -> SA Configuration -> Graphics Configuration (something like that, just find the advanced graphics menu in your modded BIOS). Set these values to turn off dGFX:

Skip Scanning of External GFX Card [Enabled]
Primary Display [iGFX]
Select PCIE Card [Elk Creek 4, IIRC, whatever sets the dGFX to ActiveLow is the correct one)
Internal Graphics [Enabled]

That should do it, now your system won't even scan for the dGFX and will appear as if it was never there. Of course this means you also cannot use external displays as all the video output ports are wired to that.

@nimaim - thanks again to you as well! And yes, I keep adding to it has been the hold up, plus I added how to do yourself too so that took more time, seems a new model each day uses similar BIOS
Will try to wrap it up today!

@nimaim - No reminder needed, did you think I forgot? It's going up now

* Edit - @nimaim - and it's up, after 3 failed attempts and several re-uploading of files/images due to poor forum file upload handling!
OverPowered TONGFANG CyberPower Machrevo MACHENIKE - Unlocked BIOS Guide W/ Files

Hello all!

I have successfully flashed the new RTX Tonfang 15" 2070 Maq-Q 80W TPD (stock) to a 90W and 115W full MAxP vbios.

The only issue is that in both cases I lose mini dp functionality so they aren't usable for me...I need external dp monitor support.

Anyone has an idea if this is a bios/uefi issue that could be edited somehow and fixed?

Any help would be amazing I've been trying to make this work all week!

Thanks!

Primary Display [iGFX]

@zill - upload both vBIOS for me and I will check them. And what do you mean, in both cases you loose dp? I assumed one is stock and one is the mod 115w, so later I assumed might give issue or need edited, why would the original one cause issue?
Or are neither you mention for your system? If neither are for your system, please also include your original. Is this a vBIOS from within the BIOS, or one you are flashing to an actual graphics card?

Hi, thanks for helping out! I am flashing the gpu not bios but could be related to the bios?

The original works fine of course and the 115W is not modified its from the full 2070 115W card thats in the bigger 17" TF chassis

I have 3 vbioses: Original, 90W from razer blade 15, and the 115W that comes from the bigger version 17" TF chassis. I was surprised that the mini dp was gone also with the 115W since their share same mobo

I have been using nvflash to flash 90W and nvflash64p (patched) to flash the 115W. The 115W doesn't play along nicely so maybe there are actually some differences to the MAx-Q cards other than a TDP limitation

I will send you the 90W version from the razer and which performs really well if I could only get the mini dp ports working it would be a dream come true!!

I was told nvidia doesn't allow any modified code to run on their RTX cards...? I mean unsigned vbioses ... ? I really hope you can make it work!

Thank you so much! I've been trying all week to make this work!

@nimaim @pcfr33k
I skipped one of the instructions to disable dGFX in OP-LP3 modded BIOS, due to which nothing comes on screen. however, keyboard lights up.

reading your post, I created a bootable dos via https://feeding.cloud.geek.nz/posts/crea...e-usb-stick-to/
Note that above link contains oldish packages (v1.0).

I pushed created autoexec.bat and auto.bat containing commands as you had suggested, as follows:

autoexec.bat
```
call auto.bat
```

auto.bat
```
@echo on
date /t
FPT.exe -bios -d origbios.bin
FDAPM.com /coldboot
```
as you can see, for testing purposes, I am extracting the bios rather than writing to it.

however, it seems laptop is not booting onto the USB. I wait for a while (~5 mins) then have no other option than to pull off the usb and switch off the laptop.

I tried this on another laptop (non cannonlake), and usb boots and shows expected error that fpt.exe is not compatible with this laptop's CPU platform.

Can you please help me in flashing the bios again. I had ordered a programmer but its still to reach me.

I thought I had instructions to make sure to enable CSM support in Bios, the problem is since this is a DOS boot you need legacy(CSM) enabled in Bios. I can walk you through step by step what to do blindly.

Let me do this now to get you back up and running. Ill come back edit this post and get you simple instructions.

Ok Lets get you back up and running. Leave your USB device in USB.

1) Use your iPhone or Android stopwatch, as soon as you click the power button simultaneously click the power button
2) At 6-7 seconds 6 seconds is best click the function key F2 once.
3) Click right arrow key 3 times
4) Click Enter
5) Click down arrow once
6) click enter
7) Clcik right arrow key 5 times
8) click enter
9) click enter

it should take about 5 minutes but wait 10 minutes for the bios to flash, I actually added another command to make it reboot once it completed, I forgot where I posted that but if it was not in my original post just wait 10 minutes to be safe.

Also please leave the Bios set to CSM enabled during your testing of the Bios settings.

Note while CSM is enabled The OP will try to boot to legacy so you will see no boot device found so power off and right after you power up and see OP splash screen click F7 and choose your UEFI drive to boot a bit inconvenient but a must while testing your new modded Bios.

I did not use that link to create my USB I used a simpler way just use RUFUS to create a DOS bootable USB added another BAT file edited the original autoexec.bat to load my bat with all the script in it. Please look for post regarding this because no one tested nimaim method, the link he provided.

Let me know if this worked for you otherwise there is another thing you can do, disconnect the battery and the CR2023 battery, press power key for about 2 minutes, then release power button, wait about 5 minutes, connect laptop battery and CR2032 battery back that should reset that setting back to disable I would hope.

@Lost_N_BIOS thank you very much for the guide, I'm sure that took a while to write out in such detail. Much appreciated!

@geekasm, sorry, busy weekends. You're in good hands with @pcfr33k though. Yes, easiest thing to do is to remove the battery and it "should" reset you back to the failsafe settings. Without CSM enabled, you will never be able to legacy boot into something like DOS, only EFI. This obviously happens with BIOS flashes/edits and why we recommend everyone get a programmer. This is also yet another reason Optimus should die.

Thanks so much for sharing these instructions.

@pcfr33k, tried blind pressing as listed. Unfortunately, I dont think it boots into USB, for me.
Can you tell me whats implied when keyboard lights up ? Is it that its booting into windows ?
because when I press F2 around ~6 secs (I used stopwatch), within next 3-4 secs the keyboard lights up.

I ll try for switching off battery and other battery. ll keep you posted. Thanks again.

@pcfr33k thanks for your suggestions. I tried following, but was unsuccessful in either of them.

right 8 times and down 6 times => laptop stays powered up and keyboard lights stay switched on. on powering off->on manually, same as earlier.

bios reset via battery and cmos. Please look at attached pic. I removed the connectors of battery and cmos battery (highlighted circles), pushed power on button for ~2 minutes. waited 5 mins and then, reconnected battery, cmos connectors. attached the charging cable and switched on the laptop. Keyboard blinked at time=24 secs and then at time=50 secs. then, laptop stayed powered on, but no keyboard light and no lcd.
I powered it off->on after ~2 mins. this time, laptop showed same behaviour as original. keyboard light come on at ~24 secs, stay on and laptop remains powered on. But monitor doesnt come on :(

I know you are helping but what can I do now. Thank you for reading.
