Upgrading the BIOS

This section describes how to upgrade the BIOS. However, please note that upgrading the BIOS involves high

risk of damage to your computer. We strongly recommend that you contact Moxa’s TS staff for assistance and

obtain all necessary tools and files before attempting to upgrade.

Step 1: Create a Bootable USB Disk

We suggest you use the HP USB Disk Format Tool to create a bootable USB disk. You may download this tool

from the Internet. Search the Internet using the phrase “HP USB Disk Storage Format Tool”, and then

download the tool from one of the listed websites.

You will also need to download the FreeDos system files kernel.sys and command.com from

http://www.freedos.org/kernel/.

1. Copy DOS system files kernel.sys and command.com to a specified directory (C:\FreeDOS in this

example).

2. Start the HP USB Disk Storage Format Tool and select the USB device that you want to use as a bootable

disk in the Device drop down box.

3. Select FAT in the File system drop down box.

4. Type the disk name in the Volume label field.

5. Check the option Create a DOS startup disk under format options.

6. Specify the directory of the system files (for example, C:\FreeDOS).

7. Click Start to format and create the USB disk.

ATTENTION

We suggest you use a USB drive with under 2 GB in disk space, as larger USB drives may not support FAT file

format and consequently fail to boot.
