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.

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.

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.

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

1. 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.
