8.2

BIOS Update with UEFI Shell

8.2.1 Scope

The Unified Extensible Firmware Interface (EFI or UEFI for short) is a new 

model for the interface between operating systems and firmware. It 

provides a standard environment for booting an operating system and 

running pre-boot applications. 

An optional feature of a UEFI implementation is the ability to boot the 

system to a built-in shell. The UEFI shell provides a command prompt and 

a rich set of commands that extend and enhance the capability of the UEFI 

BIOS.

This section describes the process for updating the PPC12-427 BIOS 

firmware image using the built-in UEFI shell.

8.2.2 Process

1. Insert a USB flash drive containing the BIOS update program into a 

USB socket on the PPC12-427 platform.

2. Turn on the PPC12-427 and press the 

ESC

 or 

DEL

 key during the boot 

process, which starts the BIOS setup utility.

3. In the BIOS setup utility, use the cursor keys to highlight the 

Save & 

Exit

 menu option.

4. Use the cursor keys to select 

UEFI: Built-In EFI Shell

 from the list of 

boot devices displayed under the 

Boot Override

 section.
