@Fernando:
Thank you for your attention, good night.
I have not tried your method yet, I will try it tomorrow morning.
How do I know if the network and sata modules I am upgrading are compatible with my motherboard? Or is it automatic? Is there a chance that the system will not power on due to upgrading these modules? I have these concerns.
Best regards.

Bought a CH341a programmer, and flashed the modded bios to Asus M5A97 LE R2.0 EPROM (winbond 25Q64FVAIG). Now the NVMe ssd works great in booting windows 10. Thanks alot for your suggestion.

@DerBert
When u got the CH341A, read the SPI and attach here the dump or if u made any backups before the mod flash.

@MeatWar
thanks for the quick reply! Unfortunately I didnt do any backups, was a bit to naive. Only have the original .CAP file.
Alright will do attach the dump, looking forward to your tips.

hello everyone

Is there guide how to flash MSI mainboards with an AMI UEFI BIOS ??

thank you

Usually MSI doesn't pose any issues...
Use M-Flash for flashing.

@MeatWar,
CH341A arrived and I tried my luck. See the files attached (CH341AProgrammer and AsProgrammer - dont have any experience so I thougt I would just use both) Files seem to be similar?!
Thank you in advance, im at a loss right now - so for any hints or further instructions (found on winraid or other) im plenty thankful!

Hey mate... i dont need to check any files, take out the SPI from the board, put in programmer, program it with CH341 soft or AS or any other, i dont memorize with soft is for each motherboard/bios.
As the SPI is socked its an easy job, if u dont succeed with one, other will work.
Extract the bios image from the CAP using UEFItool, this is wot u will use in the programmer, not the CAP remaned.

Thank you @MeatWar ! First I had to extract the body (in Uefitool) because of size, then "programmed" it onto the IC - put it back onto MB - removed battery and changed jumper postion (CLRTC) for about 30secs - then tried a start but it didnt work.
Unfortunately with the "original extracted body" and the modified as well, so I suppose I fried something on the board?

Could you tell me if Im doing something drastically wrong? If not I think the last hope could be an already (nvme) working/flashed Bios (maybe @wfreetree could help out?)
And do you think, if nothing works, to give it a try with a new bought eeprom?
Really appreciate your patience and help!

Just focus on the original bios, not mods yet. U need to first get the board working.
Usually this is due to soft versions, as i said before.

Use UEFItool NE51, extract the UEFI image from the AMI Aptio Capsule, ull get a *.ROM, this is the correct procedure.

@MeatWar, thank you so much! Its working now with the mod, the UEFItool NE alpha 51 was the solution!
Really appreciate your help!

I am currently attempting this on an Asus Z99 Pro Gamer, and I am hitting a roadblock.

Since I do not want to install Windows just for this, I am using TianoCore to launch an EFI shell (for some odd reason, Asus is refusing to let me use the built in one, telling me to disable Secure Boot, when it already is disabled), and AfuEFI to flash the modded firmware (removed the capsule header via UEFITool from Linux on my laptop).

Flashing the .cap works fine, however when attempting to use the /GAN option, I just get the answer that it is an unrecognized command, despite the fact that the included changelog explicitly mentions /GAN's existence as a hidden option.

AfuEFI 3.07.01

@moriel5

The /GAN syntax option only works with the Aptio IV AMIAFUwin 3.05.04, not higher versions.
