7-12 UEFI BIOS Recovery Instructions

Attention! Do not upgrade the BIOS unless your system has a BIOS-related
issue. Flashing the wrong BIOS can cause irreparable damage to the system.
In no event shall Supermicro be liable for direct, indirect, special, incidental,
or consequential damages arising from a BIOS update. If you need to update
the BIOS, do not shut down or reset the system while the BIOS is updating to
avoid possible boot failure.

An Overview to the UEFI BIOS

The Unifi ed Extensible Firmware Interface (UEFI) specifi cation provides a software-
based interface between the operating system and the platform fi rmware in the
pre-boot environment. The UEFI specifi cation supports an architecture-independent
mechanism for add-on card initialization to allow the UEFI OS loader, which is stored
in the add-on card, to boot up the system. UEFI offers a clean, hands-off control
to a computer system at bootup.
How to Recover the UEFI BIOS Image (-the Main BIOS
Block)
A UEFI BIOS fl ash chip consists of a recovery BIOS block, comprised of two boot
blocks and a main BIOS block (a main BIOS image). The boot block contains critical
BIOS codes, including memory detection and recovery codes for the user to fl ash
a new BIOS image if the original main BIOS image is corrupted. When the system
power is on, the boot block codes execute fi rst. Once that is completed, the main
BIOS code will continue with system initialization and bootup.
Note: Follow the BIOS Recovery instructions below for BIOS recovery when
the main BIOS boot crashes. However, when the BIOS boot block crashes,
you will need to follow the procedures in Appendix D.
To Recover the Main BIOS Block Using a USB-Attached
Device
This feature allows the user to recover a BIOS image using a USB-attached device
without additional utilities used. A USB fl ash device such as a USB Flash Drive, or
a USB CD/DVD ROM/RW device can be used for this purpose. However, a USB
Hard Disk drive cannot be used for BIOS recovery at this time.
To perform UEFI BIOS recovery using a USB-attached device, follow the instructions
below.
1. Using a different machine, copy the "Super.ROM" binary image fi le into the
disc Root "\" Directory of a USB device or a writeable CD/DVD.
