BIOS is short for basic input/output system. The BIOS is built-in software that determines what a computer can do without getting programs from a disk. The BIOS has the code that controls the keyboard, display screen, disk drives, serial communications and other functions. A Phoenix Flash BIOS is written on a rewriteable memory chip on the motherboard. Some of the reasons why you would update your BIOS are for OS support, hard drive support and bug solving.
Download the Phoenix Flash BIOS upgrade from your computer motherboard manufacturer's website to your USB flash drive. You can find out your motherboard manufacturer via your computer's manual, from the BIOS version number on the start-up screen or by opening your computer case and looking at the information on the motherboard itself.
Insert the Phoenix Flash BIOS upgrade saved on the flash drive into a USB port.
Power on the computer and press F2. The Setup Mode displays.
Use the arrow keys to move the cursor to "Boot" on the "Menu" tab.
Change the boot order of the computer to allow the USB port first boot priority.
Press F10 to save and exit. The computer will restart.
Double-click the Flash BIOS upgrade file on the USB drive. The upgrade will begin automatically and reboot your computer when finished.
After the computer restarts, remember to change the boot priority back to the hard drive or other device of your choice.
