Appendix A <Flash BIOS>
A.1 <Flash tool>
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:
http://www.commell.com.tw/Download/BIOS/FPT10.rar
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 <Flash BIOS process>
1. Please make a bootable UFD which can boot into DOS enviroment.
2. Unzip the flash tool and copy it into bootable UFD.
3. Add a bin file to the same folder..
4. Power on the system and flash the BIOS under the DOS environment.
(Command: fpt –savemac –f xxx.bin)
5. Power off the system and then power on.

Appendix B <Installation driver Notes>
B.1 <iAMT(ME) driver>
Before installing, it need to install Microsoft Hotfix KB2685611 first for Win7
32/64 bit. More information please refer
https://www.microsoft.com/en-us/download/details.aspx?id=38423
B.2 <USB3.0 driver>
Before Win7 install the USB3.0 driver or use in Win8 and Win8.1, xHCI
needs to be enabled in the BIOS.
Note that if enable xHCI, all USB port will unusable in Win7. So first need
copy driver folder to your HDD, then enable xHCI, and use PS/2 to do install.
The path is “X:\Driver\USB3.0\Intel_USB_3.0_xHC_Driver_4.0.0.27_PV”
