@toonamix - how are you flashing mod BIOS right now, I mean what flash tool/method are you using? If you are using the stock BIOS package that should work OK as long as you do it correctly, edit BIOS file P750ZM.15 only with your NVME change, then copy entire stock package somewhere for flashing.
Replace your modified P750ZM.15 into the copied stock package, replacing the original file. Then run flash.bat (not flashME.bat). If that does not work, I can show you another way, but I have helped many Clevo users with similar BIOS packages and this method works every time I've seen anyone using it.

@Gkoow - To help @Fernando out, here is your mod BIOS - Merry Christmas and Happy Holidays to you both!

For those, who wish to look for 16 Megabyte capacity chip, (instead of 8 Megabyte)

Winbond 25Q128FVIQ is 8 pins, this chip is present on Asus Rampage V Extreme. Last two digits are optional (IQ). Real chip name is 25Q128FV but be careful when buying, it must be a 8 pin package type A, PDIP-8 300-mil. (Means, Type A, PDIP package, 8 pin, 3mm leg.)


Other possible options by Winbond:

25Q128FVIG
25Q128FVIP
25Q128FVIQ
25Q128FVIF

When searching at ebay for example, type W25Q128FVIQ or 25Q128FVIQ, starts from $2,60 including shipping. At aliexpress $1,79 including shipping.

But don't forget, you will need an external USB flash programmer to use it first, like CH341A.

Only one BIOS needs edited @Fernando, depending on which batch file you use or method used to flash the BIOS. I didn't check his modified BIOS files.
One BIOS is there for ME update, other for BIOS, Clevo always does this for no reason, when you could use a single BIOS for both. That is the one I mentioned him to use, P750ZM.15.
The 8MB BIOS does not need edited at all, it's not used in the flash process when updating BIOS only (Flash.bat).

However, since you had a sizing issue Fernando, you can use the 8MB BIOS, he just needs to edit the batch file then to call that BIOS for flashing instead of the other.
But since you mentioned, no problem here when inserting NvmExpressDxe_4.ffs into the 4MB BIOS, using UEFITool or MMTool?

You're welcome. I did not check your "Mod" BIOS files, only grabbed the stock package, so I do not know which you modified already. You need to mod the 4MB BIOS file, it's the only one used to flash the BIOS when using the stock flash.bat file (unless you edit that batch to use the 8MB file instead, either way will work)
If you modified the 8MB BIOS file previously, and only that file, you can modify the batch file to use that file instead. Or use the 4MB BIOS Fernando made for you, with the stock flash.bat command.
Or modify the 4MB one yourself, NvmExpressDxe_4 can be used, insert at end of Volume index 02:01-00 (TiSmartAmpSmm) with MMTool or insert after TiSmartAmpSmm w/ UEFITool

I will try soon. So I have a dubt flashme.bat (the .bat that I have used) go to flash a 8mb rom... i'm wrong? (sorry for my little english)
Flashme.bat:

fpt -f P750ZM8M.15 -l 0x400000 -y
Call flash.bat
fpt /closemnf < yes.txt
Afudos.exe /s /shutdown
 

Flashme.bat if not used for updating the BIOS, only ME, and yes that is the only command used for the 8MB BIOS file. Please do as I mentioned, it is for the 4MB BIOS file P750ZM.15, using flash.bat
Both BIOS are same, only one has Intel ME inside, FYI

Hi, can someone help me with modifying the g771jw bios? the link with the files does not work. I tried - I modified the bios using UEFITool from this post
but I can not flash it. Afudos shows that it's too big, and flash from the bios menu that it's too old ...
I found the instructions for my model
https://rog.asus.com/forum/showthread.ph...2041#post752041
but the link to the files does not work

please help

Fernando
The Asus forum link does not work where the instructions and files are. There is a reference to this forum and this topic.

I made a mod using the instructions on this topic, but I'm not able to load the bios. I tried Afudos "rom name" and it shows that it is too big (although in windows it shows the same size with the original bios). I tried to upload from the Biosu Function (it's so in my asus), but I think it's an older version.
