Supermicro UEFI BIOS Recovery Instructions User's Guide

About this manual

This manual is designed for system integrators, PC technicians, and knowledgeable users to rescue and recover the UEFI BIOS on Supermicro motherboards or systems. It explains the architecture of the AMIBIOS flash chip, distinguishing between the boot sector block and the main BIOS code block, and notes that a crashed boot sector requires an RMA repair rather than user recovery.

The guide details two methods for recovering the main BIOS block using a USB-attached device. The first method involves copying the "Super.ROM" binary image to a USB drive or CD/DVD, inserting it into the target system, and pressing and during startup to enter the recovery menu. The second method uses a bootable USB drive with the AMI.BAT utility to flash the BIOS image directly from a DOS prompt.
