4.1.4 ASUS BIOS Updater
The ASUS BIOS Updater allows you to update the BIOS from within a DOS environment.
This utility also allows you to backup the current BIOS le for use when the BIOS fails or gets
corrupted during the BIOS upgrade.
The succeeding utility screens are for reference only. The actual utility screen may not be
the same as shown here.
Before updating the BIOS
1. Prepare the motherboard support DVD and a USB ash drive. The ash drive should
have only a single partition and formatted using FAT16/FAT32.
2. Download the latest BIOS le and BIOS Updater from the ASUS website at
http://support.asus.com and save them on the USB ash drive.
NTFS is not supported under a DOS environment. Do not save the BIOS le and BIOS
Updater to a hard disk drive or USB ash drive formatted using NTFS.
3. Turn off the computer and disconnect all SATA hard disk drives (optional).
Booting the system in DOS environment
1. Insert the USB ash drive with the latest BIOS le and BIOS Updater to the USB port.
2. Boot your computer. When the ASUS Logo appears, press <F8> to display the BIOS
Boot Device Select Menu. Insert the support DVD into the optical drive and select the
optical drive as the boot device.
