7.6 UEFI BIOS Recovery

Warning: 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 do update the BIOS, do not shut down or reset the system while the BIOS is
updating to avoid possible boot failure.

Overview

The Unified Extensible Firmware Interface (UEFI) provides a software-based interface
between the operating system and the platform firmware in the pre-boot environment.
The UEFI specification 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 the
system. The UEFI offers clean, hands-off control to a computer system at bootup.

Recovering the UEFI BIOS Image

A UEFI BIOS flash chip consists of a recovery BIOS block 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 flash a new BIOS image if the original main BIOS image
is corrupted. When the system power is on, the boot block codes execute first. Once it is
completed, the main BIOS code will continue with system initialization and bootup.

Recovering the Main BIOS Block with a USB Device

If the BIOS file is corrupted and the system is not able to boot up, this feature will allow you
to recover the BIOS image using a USB-attached device. A USB flash or media drive can be
used for this purpose. Please note that a USB hard disk drive is NOT supported. Follow the
procedures on the next page to recover the BIOS.
1. Using a different machine, copy the "Super.ROM" binary image file into the disc Root "\"
directory of a USB flash or media drive with FAT16 or FAT32 format and rename the file
to SUPER.ROM.
Note: If you cannot locate the "Super.ROM" file in your drive disk, visit our website at
supermicro.com to download the correct BIOS image into a USB flash device and rename
it "SUPER.ROM".
