Bios

[Origommi]

I'm really curious about how and what is used in making the Bios whether it be on Gigabyte, ASUS, or ASrock, does anyone know?

I'm sorry, but your question makes absolutely no sense.

The bios is actually a multitude of systems

 

Starting the PC first powers on a CMOS pic chip that has a set program designed to boot the main bios

The main bios is a very small computer system in itself, made up of a small internal persistant memory, and a small CPU

This will then load code across the main CPU, do all the system checks (POST) then attempt to load a bootloader into the main system and invoke the bootloader process on the main CPU

The bootloader will take over and attempt to boot the main OS.

 

Its amazing how many layers there are tbh.
