Little x86-64 bootloader written in nasm assembly to factory reset BIOS settings overwriting the CMOS memory (NVRAM) with zeros

Compile

Use make or compile manually with nasm -fbin main.asm -o boot.bin

Emulate

This isn't so useful but use qemu, after compiling do make run

Running in to a real machine

Just flash the boot.bin file inside an usb, make sure to select the proper boot order

Will it run on UEFI?

I don't know, maybe with CSM enabled (compatibility support module) it will.

Additional notes

Read the makefile before running make clean.
