Notes on refreshing the BIOS

1. Find out the manufacturer and model of the motherboard.

When the system is powering on for self-test, press the PauseBreak key on the keyboard so that the system's self-test process will be paused.

Since the requirements for upgrading the BIOS are very strict, if there is a slight mistake during the entire refresh process, it may cause the motherboard to be scrapped. Therefore, the motherboard and BIOS model specifications must completely correspond to this, and beginners should pay special attention to this. The best way is to download it from the official website of the motherboard manufacturer to ensure that nothing goes wrong.

In addition, foreign high-end original brand machines and laptops mostly use Phoenix BIOS (currently Phoenix and Award have been merged). Which BIOS the motherboard uses can generally be known from the startup screen and the BIOS chip trademark on the motherboard.

For example, Award company's BIOS chip needs to be erased with AWDFlash. It is worth noting that some well-known motherboard manufacturers will provide special refresh programs to erase the BIOS of their products.
