@Lost_N_BIOS Well somehow I cannot create a new post on bios-mods, the textbox just disappears when I am to send a message... whatever.

I think if you could try to edit that one setting to see whether it works or not would be a step toward the right direction. (I still couldn't figure out how to find the right bits from the IRF extraction , How am I supposed to find them out?)

I have looked into editing Phoenix bioses for a whole day, and even tried to put the whole thing into IDA Pro, to see whether there are any clues about how to unlock the Adv menu. I found the tutorial you mentioned about unlocking them, but mine had a completely different structure than what's in the pdf.

Do you know how might I be able to put the programmer dump into Phoenix Bios Editor?

@randoomkiller - Try another browser there, or clean cookies/cache and see if that helps.
Yes, I see that too in the PDF, and your BIOS in any way (Stock, decompressed, dumped from PhoenixTool, dumped directly etc) does not open in Phoenix BIOS editor either, so that guide/method can't be used
I can change setting for you in setup and NVRAM, but on the NVRAM I am not sure if this is signed or checksum'd in phoenix BIOS, so may = brick
I will make some BIOS for you to test shortly

@randoomkiller - I was about to do test edit for you on that setting, but looking back at post #21, I realized you didn't give me full info/report there
The BIOS you did report on PT273UEFIT25 is non-ideal edit that I only made in case the others bricked due to tools used, the others would be better, if they were bootable (and all should have been able to install Win10 to NVME if PT273UEFIT25 could too)
So, what happened with the other two BIOS from that package, either brick, or both bootable?

@Lost_N_BIOS In #17 and #19 I have written what I experienced. It feels like it literally crashes halfway loading up everything from the bios chip, and my guess is, when it gets to load the nvmexpress, it get's into an infinite loop, and stucks there. I cannot explain it better. If the drive that's in is not an nvme, it works perfectly normal (I guess no NVME detected -> No need to look up any related function, no related thing is loaded) without any signs that it is modded. However when the 970 is in, it functions normally for half-one second, and then freezes midway. If I keep pressing F11 or F2 immediately after pressing power, the notification for loading into setup menu appears but still freezes after that 1 sec.

However, looking it up in bios-mods, the laptop seems to be rewrite protected, but not encrypted (?). We might be able to change the nvram options by just plain editing.

I was talking about 3x BIOS from post #20, you only reported on one of those BIOS

Yes, if you want to test changing that one setting I mentioned it can be done without mod BIOS, either via grub/setup_var, RU method, or dump vars with H2OUVE (Probably best)

Download the following package, and run the command below from each versions folder that directly contains it's exe. Before doing this, make sure you have secure boot disabled in BIOS, any BIOS password removed, and TPM/Encryption disabled.
Once done, copy the entire folder somewhere, delete everything but any created vars.txt and then repackage this and send to me, this way all created vars.txt remain in place in the folders of the version that created them.
