Hello. Please help me modify the firmware to support NVMe SSD.

@zokir - Is that programmer dump?? If not, please do below, and send me file from #1 (ONLY)
Once I send you back mod BIOS, you will put system to S3 sleep (not hibernate), then wait one minute, wake it up, then flash back the mod BIOS via step #2

The BIOS was copied by the TL-882 programmer.

Have you wrote to this BIOS chip on this board, with that programmer, and it was OK? I mean, you have erased and written to chip on this system, with that programmer, so you know it works?
If yes, OK, I will unlock BIOS menu and do NVME mod for you, please confirm, thanks

Dump worker 100%

@zokir - Here is your mod BIOS - https://ufile.io/lzooqqn1

*** WARNING - To ANYONE with laptop and unlocked BIOS!!!! ***
DO NOT try to enable this graphics card or disable that card, switch cards etc. Otherwise you will end up with no display output (ie black screen) and no way to recover except by blind flash or with flash programmer.
You can change graphics related settings, like changing memory sizes, or core speeds etc, just don't try to disable one card or change which is main etc.
Additionally, be very careful when trying to undervolt CPU, you can leave BIOS unbootable due to CPU voltage too low (Sometimes even 0.05 is too much)

*** WARNING *** - This BIOS is user specific! If you are not user zokir at Win-RAID.com forum, DO NOT USE THIS BIOS!!
If you do, and you are not zokir, then you will loose your serial, UUID, OG NVRAM, and possibly LAN MAC ID as well.
You have been warned!!!

Thank you so much. Tomorrow I will program the BIOS and write about the results.

@zokir - You're welcome! If you are not already familiar with NVME/OS setup etc, please see this guide and do step #4 in the "This is what you should do" section exactly as outlined

Everything is working. Only I could not find how to turn on NVMe

I flashed the BIOS with a modified firmware. The laptop stopped turning on. So the firmware is not working. I flashed with the TL-882 programmer
----------------

For verification, I returned the native firmware. Everything works with native firmware. I flashed with the TL-882 programmer

@zokir - You said working at post #9?? Only you could not find out how to use NVME (For which, I say you need to check the link I gave you at post #8, you don't "Turn on NVME" it's on already, but you do have to install OS to it a certain way)

Then you said not working at #10?? Which was it?? Did the BIOS I send you boot, or not? If not, why did you say it was working at post #9?
I have already made same edit for this user, minus the NVME insert and all is fine, so something with your write possibly? - Acer VN7-791G Advanced BIOS

Did you erase, then blank check, then write/verify? If not, that may be the problem.

I did change one extra byte in your edit that I missed when doing megan's BIOS, at above link, but same outcome would appear (unlocked menus).
If you want, I will remove that byte edit and you can test to see if it's then bootable?

* Edit - @zokir - Here, please test, this has that one byte changed back, this makes it a dirty edit, should fail (but megan said working and showed image of menus, so it works)
Ideal proper edit is the one I sent you before, with this byte properly changed

Hey. It's okay. When I first wrote the firmware with the programmer, it did not write correctly and did not work. I flashed the firmware again, then it worked. Tomorrow I will install Windows and check. Thank you for answering my topic.

@zokir - Ohhh, OK!! So good, the first BIOS I sent you works then, correct? If yes, good, and I thought it should
About NVME, be sure you follow link at post #8 to guide on how to install to NVME

Hi, today I wanted to install Windows on NVM and nothing works for me. The hard disk is not detected in the BIOS and the installation program cannot detect it at the beginning of the installation.

First, if you want to show me images of windows or BIOS, set everything to English please What does that error message say at the bottom?

Do you see PATA SS in BIOS, at boot priority or BBS selection page etc? You will never see NVME in the BIOS, this is mentioned in the guide I linked you to at step #4 - You will only see PATA SS or Windows Boot Manager once windows is installed.

BIOS should be set to UEFI mode (and or OS Type Win7-10 etc), CSM can be enabled or disabled.
This M2 port may not be compatible with NVME? But, didn't I link you to some thread at Acer forum where user showed it working? If yes, please find and send me that link again so I can look at his image

USB installer should be GPT formatted USB, and I find Windows DVD media creation tool to do this best, sometimes Rufus causes issues, so try this (Ignore Win8 in specifications, I use for Win7-10 all the time)
https://www.microsoft.com/en-us/download...s.aspx?id=56485
Info/FAQ - https://www.microsoft.com/en-us/download...d-download-tool


And, NVME should be RAW or GPT only, here's how to make RAW - You can use diskpart in windows from OS (Direct from any CMD Prompt), or from installer ISO (press Shift + F10 on the first setup screen where you pick language)
Or from repair/troubleshoot options in the installer/setup. Remove all other drives, so you have only USB and target win10 drive. Then from CMD prompt do the following

1. Diskpart
2. List Disk << Here, identify what your target disk is by size/name etc, and make note of it's #, you will use it's # next - (If in windows, these #'s will match what you see the drives shown as in Disk Management) - Be sure you do not select your USB or main OS drive if in OS
3. select disk # << Here, instead of #, put target disk #, example >> select disk 0
4. clean
5. Exit

Reboot and run the installer again, then point it at the raw/blank drive, do not load any drivers or create any partitions etc, just select drive and click next
