Automatic Firmware Update Utility

The automatic firmware update utility provides an automated process to update the
firmware on the Thor VM3. Firmware that can be updated includes BIOS, EC (Embed-
ded Controller) and Screen MCU (Micro Controller Unit). Firmware updates are distrib-
uted as cabinet (.cab) files. The .cab file contains the necessary firmware files (BIOS, EC
and Screen MCU) and a utility to install firmware files. The firmware update utility is
installed as part of the factory software load. This utility can be used to install newer
firmware or to revert to older firmware.
Use the Software tab of the
firmware versions.
It may be necessary to update firmware before installing an updated operating system.

Firmware Distribution Files

The following software files must be copied to the \System\FWUpdate folder in the
order listed. The files can be copied to the folder manually or remotely. Contact

FWxxyyzz.cab - This file contains the firmware update files and a utility to verify version
compatibility and install the firmware files. The file name is structured such that xx
identifies the last digits of the BIOS firmware version, yy identifies the Embedded Con-
troller firmware version and zz identifies the screen MCU version.
UpdateFW.tag - The file that triggers the update utility to begin. Be sure to copy this file
only after the .cab file has been copied. As soon as the Thor VM3 detects the presence of
this file, the unit reboots in five seconds.

then the .tag file.
b. The Thor VM3 automatically reboots and starts the update process after
detecting the updatefw.tag file. No user intervention is required to reboot the
Thor VM3 or run the update utility after the reboot. The update utility operates in
a DOS screen.
c. If the update is not successful, the update is tried three more times.
d. If the update fails, the \System\FWUpdate folder is cleaned up leaving
flashapp.exe, a flashlog.txt and a retry.tag file.
e. Review the flashlog.txt file. The log file lists what firmware (if any) has been
installed. If an error has occurred during the update process, it is detailed in the
flashlog.txt file.
