Please tell me how to change the version or date in the modified BIOS. Since I can not update it through the BIOS itself, it says that such version is already installed. And through Windows produces an error
3 - error: rom file size does not match existing bios size

Updates of the BIOS from Asus, is not put, says that I do not have a laptop Asus.
Bios my correct is taken from the site of Asus

there are three bios, the original, modified, and the one after which everything fell off

laid out

@Fernando,

1) Does the "small" NVme ExpressDxe version improve performance when booting W10 only ? and as well after W10 is up and running ?

2) If we decide to use the "small" version do we have first to remove the "old" NvmExpressDxe versions ?
(for instance the original from ASUS for a X99 bios, or the v2 I had inserted (2 years ago and working) for a Z77 Bios machine)

If several NVMe ExpressDxe modules are inserted into a Bios I don't understand what modules will be used effectiveley (criterias).

100PIER I'm totally agreed with Fernando

BIOS professionals highly don't recommend a replacement of manufacturer NVMe module in the BIOS to other (3-rd party).

[MODDED NVMe]: Insertion/Replacement (to any other) -> YES
[FACTORY NVMe]: Replacement -> NO

GUID is matter only if you replace the (*.efi) body inside the persistent module to the "same" series/type mod (e.g. newer/older version). This is petty rare situation.

@100PIER:
Although I don't recommend loading multiple UEFI drivers for the same hardware, I have specifically tested loading multiple instances of NvmExpressDxe as well as loading NvmExpressDxe before and after the AMI NVMe driver.
My tests showed that all of these cases resulted in a working configuration with the driver loaded first being connected to the device.

Many thanks for your recommendations.
So, on my old ASUS P8Z77-V Deluxe I will replace the "old" NVMe module into the modded BIOS with the new one "small" offered today NVMe module and let you know the results by the next week.
A contrario on my ASUS X99 and ASUS Z370 I don't replace the native NVMe modules into the BIOS, nor add the "small" version.

I have tried to replace the "Clover Team NVMe" module of my current (working fine) modded BIOS for ASUS P8Z77-V Deluxe, but I observe a strange thing.
1) Before I do any modification of the current modded BIOS I have run UBU Tool, and you can observe UBU does detect properly the "Clover team NVMe" module:



2) Then I have REPLACED this NVMe module with the "small" version:
The "replace option" does automatically a "remove" plus "replace" operation:



3) Then I have checked the replacement:



4) Then I have submitted the new modded BIOS (properly renamed) to UBU Tool and surprise the "small" NVMe module is not detected by UBU Tool !!!


Is it normal ? Do I have missed something or not done correctly the 'remove-replace' operation ?

Does the new BIOS is correct and OK to be flashed ?
