Appendix D

Dual Boot Block on Grantley Platforms

Overview

On X10 Grantley platforms, Supermicro introduces the Dual Boot Block feature that

revives the system from an inert state if the primary boot block in the ROM chip

is damaged. A boot block carries critical codes to boot the system with minimum

hardwarerequirementsfortheBIOSrecoveryash.

In the previous generation platforms, there is an onboard jumper called JBR1 to

activate the secondary boot block in the ROM chip. However, it is not convenient

for data centers and enterprises.

Boot Block feature through IPMI GUI browser and IPMI Command Sets on the X10

Grantley platforms.

activated by IPMI Command Sets as stated in Section D-2.

How to Use Dual Boot Block

Two methods on how to use the Dual Boot Block feature are introduced in the

following pages:

1. Through the IPMI GUI Browser

2. Through the IPMI Command Sets

These are user-attended operations. IPMI logic on the defective system has to be

alive and functioning. IPMI IP is known to the user.
