Appendix D

Dual Boot Block

D-1 Introduction

This motherboard supports the Dual Boot Block feature, which is the last-
ditch mechanism to recover the BIOS boot block. This section provides
an introduction to the feature.

BIOS Boot Block

A BIOS boot block is the minimum BIOS loader required to enable nec-

essary hardware components for the BIOS crisis recovery flash that will

update the main BIOS block. An on-call BIOS boot-block corruption may
occur due to a software tool issue (refer to image below) or an unex-
pected power outage during BIOS updates.

BIOS Boot Block Corruption Occurrence

When a BIOS boot block is corrupted due to an unexpected power out-
age or a software tool malfunctioning during BIOS updates, you can still
reboot the system by activating switch JBR1 on the motherboard. When
JBR1 is activated, the system will boot from a backup boot block pre-
loaded in the BIOS by the manufacturer.
