Updating AMI Platform Firmware

Netgate may provide occasional updates to the Netgate 4200 platform firmware (“firmware”) for security fixes or other stability improvements. The firmware cannot be updated automatically, it must be updated manually. This document describes a simple method for updating the firmware using a USB mass storage device.

When this is necessary, Netgate will provide a means for owners of Netgate 4200 hardware to download the firmware files directly.

Note

This method only updates the main firmware area, it does not update the management engine or microcontroller.

Updating the firmware is relatively straightforward but requires rebooting the device and accessing the firmware configuration. The device will be offline during this time, so these actions must be performed from a local serial console either directly connected to a client system or by other means of out-of-band access.

Prepare a USB Drive

The firmware can read its update file from a DOS (FAT) formatted partition on a USB drive. USB drives can be formatted in this manner by most operating systems.

Note

Some large USB drives may not support this filesystem type. If OS does not offer this filesystem type as a choice when formatting the USB drive, try a smaller drive.

Copy the firmware file, e.g. 2AZRT81.rom, to the DOS partition on the USB drive.

Plug the USB drive into the USB port on the 4200 (Input and Output Ports).

Access the Firmware Configuration

The first task is to access the firmware configuration as follows:

• Connect to the serial console.

• Reboot the device.

• During the boot sequence, press either the Del or Esc key when prompted to enter the firmware configuration.

  This action will trigger a dialog prompt for a storage device.

• Select the USB device with the DOS partition.

  The listed size should match the size of the drive.

  

  Select a Storage Device for AMI Firmware Update

  This action will trigger a dialog prompt for the firmware update file.

• Select the firmware update file from the list, for example 2AZRT81.rom.

  

  Select an AMI Firmware Update File

  This action will close the selection dialog and return to the Firmware Update tab.

• Confirm the selected image file is displayed at the top of the Firmware Update tab.

  When the upgrade completes, the device will prompt to reset.

• Reset the system by pressing a key (e.g. Enter or Space) when prompted.

  

  AMI Firmware Update Complete

After pressing a key, the device will reboot with the new firmware.

Confirm the Update

To confirm the update, enter the firmware again and check the version reported on the first screen.

• During the boot sequence, press either the Del or Esc key when prompted to enter the firmware configuration.
