I was looking into upgrading the BIOS on my new build, as it is out of date, and the instructions say to create a "motherboard support DVD" to boot from along with the BIOS image itself and the tool on a USB flash drive. I can't for the life of me figure out how to make this DVD. I've searched around and haven't been able to find any information. Is the disc that came with the MOBO the support DVD?
I can't see why you would need it. If you intend to use a USB drive then you will use the EZ flash 2 utility. Make sure you have an unzipped version of the newest BIOS on an un-partitioned USB stick, insert it, boot to the BIOS and choose the EZ flash utility in Tools. Choose the file and follow the instructions. It's very easy.
The only reference I have in my Asus M5a99x EVO MB manual for the support DVD has to do with copying a "freeDOS" environment to the USB drive for a DOS Boot. Unnecessary!
You wrote. instructions say to create a "motherboard support DVD" . I don't see that, I see "prepare" not create. That means take out the motherboard support DVD (disc that came with the MOBO) and use it to start the FreeDOS command prompt item.
I would recommend not using the ASUS BIOS Updater and would use EZ Flash 2 program instead, but the choice is yours.
