Chapter 2: Basic Installation

USB BIOS Flashback allows you to easily update the BIOS without entering the existing

BIOS or operating system. Simply insert a USB storage device to the USB port (the USB port 

hole marked in green on the I/O shield) then press the USB BIOS Flashback button for three

seconds to automatically update the BIOS.
To use USB BIOS Flashback:

1.   Download the latest BIOS from the support site at www.asus.com/support/ and save it 

to as USB storage device.

•

We recommend you to use a USB 2.0 storage device to save the latest BIOS version

for better compatibility and stability.

•

When downloading or updating the BIOS file, rename it as P10SMWSI.CAP for this 

motherboard.

2.

Insert the USB storage device to the USB Flashback port.

Refer to section 2.3.1 Rear I/O connection for the location of the USB port that supports 

USB BIOS Flashback.

3. 

Shut down your computer.

4.

Press the BIOS Flashback button for three seconds until the Flashback LED blinks

three times, indicating that the BIOS Flashback function is working.

•

Do not unplug portable disk, power system, or press the CLR_CMOS button while

BIOS update is ongoing, otherwise update will be interrupted. In case of interruption, 

please follow the steps again.

•

If the light flashes for five seconds and turns into a solid light, this means that

the BIOS Flashback is not operating properly. This may be caused by improper

installation of the USB storage device and filename/file format error. If this scenario

happens, please restart the system to turn off the light.

•

Updating BIOS may have risks. If the BIOS program is damaged during the process

and results to the system’s failure to boot up, please contact your local ASUS Service 

Center.

For more BIOS update utilities in BIOS setup, refer to the section 3.1 Managing and 

in Chapter 3.
