6.5 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 to avoid possible boot failure.

Overview

The Unied Extensible Firmware Interface (UEFI) provides a software-based interface

between the operating system and the platform rmware in the pre-boot environment. The

UEFI specication supports an architecture-independent mechanism that will allow the UEFI

OS loader stored in an add-on card to boot the system. The UEFI o󰀨ers clean, hands-o󰀨

management to a computer during system boot.

Recovering the UEFI BIOS Image

A UEFI BIOS ash chip consists of a recovery BIOS block and a main BIOS block (a main

BIOS image). The recovery block contains critical BIOS codes, including memory detection

and recovery codes for the user to ash a healthy BIOS image if the original main BIOS image

is corrupted. When the system power is turned on, the recovery block codes execute rst.

Once this process is complete, the main BIOS code will continue with system initialization

and the remaining POST (Power-On Self-Test) routines.

Note 1: Follow the BIOS recovery instructions below for BIOS recovery when the main BIOS

block crashes.

Note 2: When the BIOS recovery block crashes, you will need to follow the procedures

to make a Returned Merchandise Authorization (RMA) request. Also, you may use the

Supermicro Update Manager (SUM) Out-of-Band (https://www.supermicro.com.tw/products/

nfo/SMS_SUM.cfm) to reash the BIOS.

Recovering the Main BIOS Block with a USB Device

This feature allows the user to recover the main BIOS image using a USB-attached device

without additional utilities used. A USB ash device such as a USB Flash Drive, or a USB

CD/DVD ROM/RW device can be used for this purpose. However, a USB Hard Disk drive

cannot be used for BIOS recovery at this time.

The le system supported by the recovery block is FAT (including FAT12, FAT16, and FAT32)

which is installed on a bootable or non-bootable USB-attached device. However, the BIOS

might need several minutes to locate the SUPER.ROM le if the media size becomes too

large due to the huge volumes of folders and les stored in the device.

To perform UEFI BIOS recovery using a USB-attached device, follow the instructions below.

6.4 Crash Dump Using the BMC Dashboard

In the event of a processor internal error (IERR) that crashes your system, you may want to

provide information to support sta󰀨. You can download a crash dump of status information

using the BMC Dashboard. The BMC manual is available at https://www.supermicro.com/

manuals/other/BMC_IPMI_X13_H13.pdf.

Check Error Log

1. Access the BMC web interface.

2. Click the Server Health tab, then Event Log to verify an IERR error.

Figure 6-5. BMC Event Log

In the event of an IERR, the BMC executes a crash dump. You must download the crash

dump and save it.
