Why does the motherboard have two BIOS chips?
If you have two, one can try to reflash the other or act as a substitute. This a safety feature for extreme overclockers who spend much time changing settings in the BIOS more or less. EEPROM chips only have so many read/write operations. Most BIOS changes require a reboot.
How does a BIOS chip work?
BIOS is a program made accessible to the microprocessor on an erasable programmable read-only memory (EPROM) chip. When users turn on their computers, the microprocessor passes control to the BIOS program, which is always located in the same place on EPROM.
What is a boot process?
In computing, booting is the process of starting up a computer. It can be started by hardware, such as pressing a button or a software command.
