Hi Ppl,
I have just spent a number of days learning about NVME and Bios after having a vendor
install an NVME drive as replacement for an M2 and then claiming that my system was dead.
Needless to say, I just didnt buy his story but, this has cost me a lot of time and potentially a lot of future work.
I hope someone would be kind enough to assist me with this mod.
I am very impressed that this Forum actually exists it gives me hope for system integrity and advancement, cheers 
System Board Id 2333
CPU i7-4720HQ
Bios version F. 45
F.46 is now available
Bios Vendor: Insyde

@watts - Hey! 
Please link me to your stock BIOS download, I can’t find any download page with the model info you have in title, or even by looking for HP M2X20PA only.
Wait, is it this one 15-5108tx, ver 47 available now - https://support.hp.com/us-en/drivers/sel…201?sku=M2X20PA
Check BIOS main page and see if ME FW version is shown, if not then download HWINFO64 and on the large window on left side, expand motherboard and find ME area, inside that get the ME Firmware version.
Once you have that, go to this thread and in the section “C” download the matching ME System Tools Package (ie if ME FW version = 10.x get V10 package, if 9.0-9.1 get V9.1 package, if 9.5 or above get V9.5 package etc)
Intel Management Engine: Drivers, Firmware & System Tools
Once downloaded, inside you will find Flash Programming Tool folder, and inside that a Windows or Win/Win32 folder. Select that Win folder, hold shift and press right click, choose open command window here (Not power shell).
At the command prompt type the following command and send me the created file to modify >> FPTw.exe -bios -d biosreg.bin
Right after you do that, try to write back the BIOS Region dump and see if you get any error, if you do show me image of the command entered and the error give >> FPTw.exe -bios -f biosreg.bin
If you are stuck on Win10 and cannot easily get command prompt, and method I mentioned above does not work for you, here is some links that should help
Or, copy all contents from the Flash Programming Tool \ DOS folder to the root of a USB Bootable disk and do the dump from DOS (FPT.exe -bios -d biosreg.bin)

Please also fine the MEinfo folder, and run this command and show me image of the bottom of the report >> MEInfowin.exe -verbose
