5-54 BIOS Updating Procedure
SPI/BIOS Updating Procedures
When replacing a 7746 Motherboard in the field, the BIOS will need to be flashed to the
latest version based on the OS Platform running on the Terminal (Windows or
Android).
Using the bootable USB Memory key
1. Unzip the USB BIOS files to the root of the USB drive.
Note: Ensure the subdirectory structures are intact.
2. Place the BIOS/SPI Update USB Key in an available and enabled USB port.
3. Validate that the BIOS configuration setup has the USB Key as the first boot device
in the Boot menu, or use the F8 BBS menu to force the USB key to be booted.
4.
Reboot the system. Use the F8 key to force booting from the USB key. The flash
process will automatically begin.
5. Once the update is complete, a key press will initiate a reboot. The reboot is
important to ensure the BIOS initializes properly. Do not interrupt the reboot
process.
Note: After the update has completed and the terminal is rebooted, the terminal
may reboot additional times as it powers up. This is normal and expected behavior
due to the nature of the features of the BIOS/SPI.
Using the Window Flash executable
1. Close all running programs prior to updating the BIOS.
2.
To run the executable, right–click on the file and select Run as administrator.
3. The user will be prompted to press a key to initiate the flash update.
4. The terminal will reboot after the flash process has completed. The reboot is
important to ensure the BIOS initializes properly. Do not interrupt the reboot
process.
