How to upgrade BIOS

Things You’ll Need:

• BIOS Chips

Step 1:
Check your computer or motherboard manual for any information about upgrading the BIOS.

Step 2:
Reboot your computer and enter the Setup screen. Check your computer or motherboard manual for information on how to do this.

Step 3:
Press the Print Screen key to make a record of each page of your settings.

Step 4:
Find out the manufacturer and model of your current BIOS. Check for the information as your computer boots, or find it in the Setup screen information you printed. If neither method works, check the BIOS chip for identifying information.

Step 5:
Check the manufacturer’s Web site to see if the BIOS can be "flash" upgraded. If so, download the utility program. If not, proceed to Step 8.

Step 6:
Copy the program to a floppy disk.

Step 7:
Follow the manufacturer’s instructions for running the program. Skip to Step 10.

Step 8:
Contact the manufacturer of your BIOS chip to find out if an updated chip is available, and if that chip will fit into the same slot on your motherboard.

Step 9:
Get and install a new BIOS chip, if available. Search the Internet for installation instructions.

Step 10:
Reboot your computer and enter the Setup screen. Change the Setup back to the previous settings if necessary or desired.

Tips & Warnings

• Your motherboard may need to be replaced in order to upgrade the BIOS. If so, consider buying a new computer instead.
• If you use flash BIOS software that wasn’t specifically made for your BIOS model, the computer probably won’t boot.
• If you install the BIOS incorrectly, the computer probably won’t boot. If you do not understand the instructions or lack good manual dexterity, have a qualified technician install the BIOS for you.
