2. Remove the BIOS chip from the motherboard and insert it into the programmer.
3. Connect the programmer to a computer that has the new BIOS firmware.
4. Use the programmer software to flash the new firmware to the BIOS chip.
5. Reinstall the BIOS chip onto the motherboard and test the system.

Method 3: Using a Recovery Disk
