Appendix A

A.1
The board is based on Phoenix BIOS and can be updated easily by the BIOS auto flash tool. You can download the tool online at the address below: FPT Tool
The tool’s file name is “FPT.exe”, it’s the utility that can write the data into the BIOS flash chip and update the BIOS.

A.2

1. Extract the zip file(re-flash tool and BIOS file) to root of the USB flash drive.
2. Insert your USB flash drive in USB port of the board and power on the system.
3. Press F5 in the Phoenix Logo screen
4. Click the Internal Shell, then input the “fs0:” command to switch to the root of the USB flash drive.
5. Type the ” fpt -savemac -f xxx.bin” command to start flash BIOS processes. ( xxx.bin means the BIOS file that you want to update)
6. When it finished all update processes, restart the system.

Appendix B
According your panel, it needs to select the correct resolution in the BIOS. If there is no fit your panel type, please feedback for us to make OEM model.
Find the setting from
Advanced->Motherboard Advanced menu->LVDS Configuration
EDID Panel type: There are 7 resolutions in LCD Panel Type, if your panel is not in the list, please contact tech@commell.com.tw
LVDS Bus: Select Single / Dual channel
Panel Color Depth: Select VESA 24 bit / JEIDA 24 bit / VESA and JEIDA 18 bit

Appendix C
The watchdog timer makes the system auto-reset while it stops to work for a period. The integrated watchdog timer can be setup as system reset mode by program. You can select Timer setting in the BIOS, after setting the time options, the system will reset according to the period of your selection. Find the setting from Advanced⇒Motherboard Advanced Menu->Power Advanced menu-> Watch dog timer select
