[Help] How to dump bios to file

I have an Asus UX481FL Laptop with AMI Bios. How do I dumb my bios to file? Major Geeks tool doesn’t recognize my bios. I also tried downloading the bios from Asus’s webiste but all I get is a .305 file. Any help is appreciated.

What is your goal?

If you have already modified the BIOS in ANY way, you will need to re-flash it back to factory defaults using factory method (NOT FPT)!!!

If you do not have Intel ME drivers installed, install them now from your system driver download page, then start over here after reboot.
Check your BIOS’ main page and see if ME FW version is shown. If not then > DOWNLOAD HWINFO64 HERE <

Once HWINFO is open, look at the large window on the left side, expand motherboard, and find the ME area.
Inside that section is the ME Firmware version. Take note of the version. (ie. write it down or get a screenshot)

Once you have that, go to the thread linked below, and in the section “C.2” find and download the matching ME System Tools Package for your system.
(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)
> DOWNLOAD " ME System Tools " packages HERE <

Once downloaded, inside you will find Flash Programming Tool folder, and then inside that a Windows or Win/Win32 folder (NOT x64).
Highlight that Win/Win32 folder, then hold shift and press right click. Choose “open command window here” (Not power shell! >> * See Registry file below *).

If you get an error, reply to this post with a screenshot of it, OR write down the EXACT command entered and the EXACT error given.

((If “open command window here” does not appear, look for the “Simple Registry Edit” below…))

Now you should be at the command prompt.
You are going to BACKUP the factory un-modified firmware, so type the following command:
Command: " FPTw.exe -bios -d biosreg.bin "

>> Attach the saved "biosreg.bin ", placed into a compressed ZIP/RAR file, to your next post!!! <<

Right after you do that, try to write back the BIOS Region dump and see if you get any error(s).
Command: " FPTw.exe -bios -f biosreg.bin "
^^ This step is important! Don’t forget! ^^

If you get an error, reply to this post with a screenshot of it, OR write down the EXACT command entered and the EXACT error given.

Here is a SIMPLE REGISTRY EDIT that adds “Open command window here as Administrator” to the right click menu, instead of Power Shell
Double-click downloaded file to install. Reboot after install may be required
> CLICK HERE TO DOWNLOAD CMD PROMPT REGISTRY ENTRY <

If the windows method above does NOT work for you…
Then you may have to copy all contents from the Flash Programming Tool \ DOS folder to the root of a Bootable USB disk and do the dump from DOS
( DOS command: " FPT.exe -bios -d biosreg.bin " )

I want to mod the bios to change the tri point temperature (the point where the fans spin 100%).

You need V14.0 ME System tools, link in above spoiler. Then do dump as mentioned above, but DO NOT do step #2

Before you do that, we need to use MEINFO from the system tools package to see if Boot Guard is enabled at chipset side, if key is burned into FPF PCH Fuses then you cannot edit much of the BIOS in the way you wanted
Due to some things I see, I assume it’s enabled. YOu will be able to tell if you see Measured or Verified Boot enabled at left/FPF side of report below

From MEINFO folder, run this command and show me image of bottom of the report >> MEINFOWin.exe -verbose

However, you may be able to change what you want using grub and setup_var, using variables below and this guide (Start at step #6, variables are below for your BIOS and the settings you want to mess with) - [GUIDE] Grub Fix Intel FPT Error 280 or 368 - BIOS Lock Asus/Other Mod BIOS Flash

Sorry, but which one is step #2?

Here is the report.

Following your first response, here is my biosreg.bin file. But an error occurred when I tried to write back the bios region dump.

What should I do next?
