How to Update the BIOS on the CloudGen Firewall F800B or F900A

  • Last updated on

A BIOS update is needed if you want to use the M805 network module in a Barracuda CloudGen Firewall F800B or F900 Rev A.

Do not update the BIOS unless directly instructed to do so by Barracuda Technical Support.

Before You Begin

  • Verify the firewall is running firmware 5.2.10 or 5.4.2 with Hotfix 597 or higher.
  • Go to CONTROL > Resources > Mainboard Info and verify that the BIOS date is before 05/13/2014. Firewalls with a BIOS date 05/13/2014 or newer do not need to be updated.
  • Download Rufus: http://rufus.akeo.ie/
  • Download the BIOS update archive for your model using the link you received from Barracuda Technical Support.

Step 1. Create a Bootable FreeDOS USB Drive

You must create a bootable FreeDOS USB drive to be able to update the BIOS.

  1. Plug in your USB drive.

    All data on the USB will be lost.

  2. Launch Rufus. 
  3. Configure a bootable FreeDOS USB drive:
    • Device – Select your USB drive.
    • Partition scheme – Select MBR partition scheme for BIOS or UEFI
    • File system – Select FAT32.
