Thank you for your reply.
I have read the ‘[Guide] How to flash a modded AMI UEFI BIOS’
Usage of the ASUS “USB Flashback” feature
However, my question is how to prepare the moded .cap file?
I have the original A.cap file.
extract body to A.rom file
MMtool, open rom file, insert Nvme to A.rom file, save as, get the ready flast B.rom file.
What is the next step please?
How to convert B.rom back to B.cap?
Or just flash B.rom file by ASUS “USB Flashback” feature?
many thanks
