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 need to update the BIOS, do not shut down or reset the system while the BIOS
is updating. Doing so may cause a boot failure.
C.1 Overview
The Unied Extensible Firmware Interface (UEFI) provides a software-based interface
between the operating system and the platform rmware in the pre-boot environment.
The UEFI speci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 the
system. The UEFI o󰀨ers clean, hands-o󰀨 control to a computer system at bootup.
C.2 Recovering the UEFI BIOS Image
A UEFI BIOS ash 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 ash a new BIOS image if the original main BIOS image
is corrupted. When the system power is on, the boot block codes execute rst. Once it is
completed, the main BIOS code will continue with system initialization and bootup.
C.3 Recovering the BIOS Block with a USB Device
This feature allows the user to recover a BIOS image using a USB-attached device without
the need for additional utilities. A USB ash device such as a USB ash drive or a USB CD/
DVD device can be used for this purpose. A USB hard disk drive cannot be used for BIOS
recovery at this time.
The le system supported by UEFI is FAT (including FAT12, FAT16, and FAT32) installed on
a bootable or non-bootable USB-attached device. Note that the BIOS might need several
minutes to locate the SUPER.ROM le if the media size becomes too large because it contains
too many folders and les.
To perform UEFI BIOS recovery using a USB-attached device, follow the instructions below.
1. Using a di󰀨erent system, copy the "Super.ROM" binary image le into the disc Root "\"
Directory of a USB device or a writeable CD/DVD.
