Even though all bios settings are shown here for reference, only a few changes are required. Those are noted in RED
To replace the CMOS battery [CR2032 (+3 Volts) BOTH BOARD TYPES] in an Axia GPIO/PS unit, it is necessary to reset all of the BIOS configurations, including the option to boot the motherboard when power is applied to the unit. Since this configuration is lost when the battery is removed, it is necessary to short the power pins on the board to start the computer after the new battery is installed.
First Start
EPIA-M Example
Attach a keyboard and monitor to the internal connections on the motherboard. Short the PWR pins 6 and 8 pins to boot the unit.
NANO Example
Resetting the BIOS configurations
VIA EPIA-M board (no USB)
To program BIOS for the VIA EPIA-M motherboard in the Element GPIO you will need:
A keyboard w/PS2 connector
A Monitor
Connect keyboard to the proper jack.
Connect power and using a small screwdriver short pins 6 and 8 together on the connector “Fpanel” (front right corner) to simulate a power on button press. Note that Pin 15 is missing from header.
Immediately after shorting the pins keep tapping the “DEL” key until the BIOS config screen appears.

VIA NANO M-830 board
To program BIOS for the VIA NANO motherboard in the Element GPIO you will need:
A keyboard w/USB connector
A Monitor
Connect USB keyboard to the any of the USB ports.
Connect power and using a small screwdriver short the PWR (power) pins together on the connector “F PANEL 1” (front right corner) to simulate a power on button press.
Immediately after shorting the pins keep tapping the “DEL” key until the BIOS configuration screen appears.
