2.3.1.5 Entering BIOS Setup
To enter the BIOS Setup Utility using a keyboard (or emulated keyboard), press the <F2> function key during
boot time when the OEM or Intel Logo Screen or the POST Diagnostic Screen is displayed.
The following instructional message is displayed on the Diagnostic Screen or under the Quiet Boot Logo
Screen:
Press <F2> to enter setup, <F6> Boot Menu, <F12> Network Boot
Note: With a USB keyboard, it is important to wait until the BIOS “discovers” the keyboard and beeps – until
the USB Controller has been initialized and the USB keyboard activated, key presses will not be read by the
system.
When the Setup Utility is entered, the Main screen is displayed initially. However, in the event a serious error
occurs during POST, the system will enter the BIOS Setup Utility and display the Error Manager screen
instead of the Main screen.

2.3.1.6 BIOS Update Capability
In order to bring BIOS fixes or new features into the system, it will be necessary to replace the current
installed BIOS image with an updated one. The BIOS image can be updated using a standalone IFLASH32
utility in the uEFI shell, or can be done using the OFU utility program under a supported operating system.
2.3.1.7 BIOS Recovery
If a system is completely unable to boot successfully to an OS, hangs during POST, or even hangs and fails to
start executing POST, it may be necessary to perform a BIOS Recovery procedure, which can replace a
defective copy of the Primary BIOS.
The BIOS provides three mechanisms to start the BIOS recovery process, which is called Recovery Mode:
•
Recovery Mode Jumper – this jumper causes the BIOS to boot in Recovery Mode
•
The Boot Block detects partial BIOS update and automatically boots in Recovery Mode
•
The BMC asserts Recovery Mode GPIO in case of partial BIOS update and FRB2 time-out
The BIOS Recovery takes place without any external media or Mass Storage device as it utilizes a Backup
BIOS image inside the BIOS flash in Recovery Mode.
The Recovery procedure is included here for general reference. However, if in conflict, the instructions in the
BIOS Release Notes are the definitive version.
When the BIOS Recovery Jumper is set (See Figure 5. Jumper Block Identification), the BIOS begins by
logging a ‘Recovery Start’ event to the System Event Log (SEL). It then loads and boots with a Backup BIOS
image residing in the BIOS flash device. This process takes place before any video or console is available.
The system boots to the embedded uEFI shell, and a ‘Recovery Complete’ event is logged to the SEL. From
the uEFI Shell, the BIOS can then be updated using a standard BIOS update procedure, defined in Update
