Updating bios from usb
This is usually due to a motherboard not having support for a new CPU, and can be fixed by doing a BIOS update.The really old way of doing this using a floppy disk.(Select Tools YES)Wait for your system to check current BIOS information. Select the drive letter with the BIOS update file, then select the file. After the file check is finished, click "Yes" to update your BIOS. When the update is finished, remove the floppy or USB drive and reboot.Enter the BIOS Menu and load "Setup Default."Reboot. If it isn't installed already, install the ASUS Update utility.That confused me a little when rebooting and finding one of the processors missing. I wanted to flash my graphic’s card BIOS today, which has to be done using “nvflash” under DOS.Unfortunately booting freedos from sysresccd didn’t do the trick, because freedos doesn’t recognize modern filesystems or the partition on my usbstick.You can also locate your current BIOS while in Windows.Press Window Key R to access the “RUN” command window.
Select "Update BIOS" from the "Internet option" drop-down menu. Once you have extracted it, you should have a flash file (the file extensions on these are completely random) and a flashing program (something like FLASHSPI. Remember the grub menu is now hidden, so keep any key pressed during the boot reach it. On the GA-P55-UD3 board, that option (F9 to EZflash) appeared after doing the update.
