AX4B / AX4B Pro Online Manual BI O S U p g r a d e By flashing your motherboard, you agree to accept the possibility of BIOS flash failure. If you motherboard is working and is stable, and there are no major bugs that were fixed by a latter BIOS revision, we recommend that you DO NOT try to upgrade your BIOS. By doing so, you are taking a risk of BIOS flash failure. If you indeed intent on upgrading, PLEASE BE SURE to use the right BIOS revision for the right motherboard model.
AX4B / AX4B Pro Online Manual Below are the steps for easy flashing procedures: (applies for Award BIOS ONLY) 1. Download new BIOS upgrade zip file from AOpen's web site. For example, AX4BP102.ZIP. 2. Run shareware PKUNZIP (http://www.pkware.com/) which supports miscellaneous operation systems to extract the binary BIOS file and the flash utility. Or Winzip (http://www.winzip.com/) in Windows environment. 3. Save the unzipped file into a bootable floppy disk. For example, AX4BP102.BIN & AX4BP102.
