Chapter 4 <BIOS Setup>
The motherboard uses the Phoenix BIOS for the system configuration. The Phoenix
BIOS in the single board computer is a customized version of the industrial standar d
BIOS for IBM PC AT-compatible computers. It supports Intel x86 and compatible CPU
architecture based processors and computers. The BIOS provides critical low-level
support for the system central processing, memory and I/O sub-systems.
The BIOS setup program of the single board computer let the customers modify the
basic configuration setting. The settings are stored in a dedicated battery-backed
memory, NVRAM, retains the information when the power is turned off. If the battery
runs out of the power, then the settings of BIOS will come back to the default setting.
The BIOS section of the manual is subject to change without notice and is provided here
for reference purpose only. The settings and configurations of the BIOS are current at
the time of print, and therefore they may not be exactly the same as that displayed on
your screen.
To activate CMOS Setup program, press <DEL> key immediatel y after you turn on
the system. The following message “Press DEL to enter SETUP” should appear in the
lower left hand corner of your screen. When you enter the CMOS Setup Utility, the Main
Menu will be displayed as Figure 4-1. You can use arrow keys to select your function,
press <Enter> key to accept the selection and enter the sub-menu.
then input the“fs0:”command to switch to the root of the USB flash
drive.

4. Type the ” fpt64.efi -y -f xxx.bin” command to start flash BIOS
processes. ( xxx.bin means the BIOS file that you want to update)
5. When it finished all update processes, restart the system.
Any question about the BIOS re-flash please contact your distributors or visit the
