BIOS
BIOS chips are on module by default. This allows the user to place BIOS chip on the
carrier board with appropriate design and jumper settings on BIOS_DIS#[1:0].
Notice: If the system CMOS is cleared, we strongly suggest going to the BIOS setup
menu and loading default settings following the first boot up.
Purpose: The standard module has no jumper at SCN1. Therefore, the BIOS settings
are maintained without a RTC coin battery. If you need to restore the BIOS default
settings, please follow the steps below:
