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 (Embedded Controller) and Screen MCU (Micro Controller Unit). Firmware updates are dis-
tributed 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
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 firm-
ware files. The file name is structured such that xx identifies the last digits of the BIOS firmware version, yy identifies the
Embedded Controller 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.

Update Process

1. Copy the files listed above to the \System\FWUpdate folder. Copy the.cab file first then the .tag file.
Be sure to copy the updatefw.tag file to the \System\FWUpdate folder last. The Thor VM3 begins the reboot process
after detecting this file.
2. 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.
3. If the update is not successful, the update is tried three more times.
4. If the update fails, the \System\FWUpdate folder is cleaned up leaving flashapp.exe, a flashlog.txt and a retry.tag file.
5. 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.
6. Review the Software tab of the
