Upgrading the BIOS

This section describes how to upgrade the BIOS.

WARNING

An improper BIOS upgrade process may permanently damage the computer. We strongly recommend that you

contact Moxa technical support for assistance to obtain all

the necessary tools and the most up-to-date

advice

before attempting to upgrade the BIOS on any Moxa device

Step 1: Create a Bootable USB Disk

Before upgrading the BIOS, every user should first create a bootable USB drive as a system rescue device.

A useful software suite for creating USB RAM drives can be found by searching for Rufus, which can then be

downloaded and used to create a bootable RAM drive.

Complete the following steps to create a bootable USB disk using Rufus:

Start Rufus and then in the “Device” drop-down list

select the USB device that you want to use as a

bootable disk.

Select MBR partition scheme for BIOS or UEFI

computers from the “Partition scheme and target

system type” drop-down list so it can boot from a

legacy BIOS or UEFI.

Select FAT32 (Default) from the “File system”

drop-down list.

Select 4096 bytes (Default) from the “Cluster size

”

drop-down list.

Enter a drive name in the “New volume label” input

box.

Select the Quick format, Create a bootable disk

using FreeDOS, and Create extended label and

icon files options.

Click Start to format and create the bootable USB

drive.

ATTENTION

When you use

a USB drive larger than 4 GB, you will need to convert the file system type to FAT32.

Step 2: Prepare the Upgrade File

You must use the BIOS upgrade installation file to upgrade the BIOS. Contact Moxa technical support for

assistance.

1. Get the BIOS upgrade installation file.

The file name should be in the format: 24AxxSxx.exe (where “xx” refers to the version numbers).

2. Copy the file to the bootable USB drive.
