4.4 Motherboard BIOS settings
The POS terminal has a BIOS (Basic Input Output System) chip on the motherboard.
Every time you start the terminals, the system will first run the BIOS self-test
routine to check the main components of the system to ensure it is working
properly.
The terminal is loaded with default BIOS settings in the factory. Please do not
change the parameters in the BIOS unless necessary.
In the following situations, you need to run the BIOS setup:
1) Error message appears on the screen during the system self-test and requested
to enter BIOS setup.
2) If you need to change the factory default settings to customized application
requirements (for example, boot device priorities).
