Handle hardware initialization (e.g., SATA controllers, network chips). This specific version is widely considered a staple

If you are running an older motherboard but want to upgrade to a newer CPU (within the same socket family, like modified Intel Xeon chips), you can use MMTool to update the CPU microcode, ensuring the motherboard recognizes the new processor. 3. Inserting Option ROMs

If you modify BIOS files frequently, purchase a cheap CH341A USB hardware programmer. This allows you to rewrite the physical BIOS chip if your flash goes wrong.
