You can use mmtool or cbrom mod your bios.yes, i understand. the point is i have absolutely no idea how to "link" the nvme mod to the bios.
Ismail did know how to do it. I dont. And.... well, unless someone reading this message knows and can teach us, that s it.
changing the drive id is easy, it s a simple hex patch. but i have no clue on how to make a mod recognized and "active" in an existing bios, i lack the knowledge. The OP knew but real life matters (earthquake) made it so he couldnt continue the job.
I know there is another forum, where "Fernando" was posting modded bios for Raid / Intel Sata matters, where people do patch UEFI bios for nvme support. Maybe you can ask there so someone explains you how to do it, or maybe, will do it. But here..... no one is that much specialized.
goodluck
It is not only easy to use but also alot of fun.
