6.10 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. Doing so may cause a 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 that will allow the UEFI
OS loader stored in an add-on card to boot the system. The UEFI offers clean, hands-off
management to a computer during system boot.
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 BIOS Block with a USB Device
If the BIOS file is corrupted and the system is not able to boot up, you can recover the BIOS
image using a USB-attached device. A USB flash drive or a USB CD/DVD ROM drive may
be used for this purpose. Note that a USB hard disk drive is
not
supported.
Recovering the BIOS Block

Using a different system, from your driver disk, copy the standard BIOS binary image file
into the root directory of a USB flash drive with FAT16 or FAT32 format and rename the
file to SUPER.ROM.
Note:
If you cannot locate the SUPER.ROM file in your driver disk, visit our website at
www.supermicro.com to download the correct BIOS image into a USB flash device and
rename it SUPER.ROM.
