BIOS Modus of the DM 7080 HD

Differently as with other boxes, the BIOS is reached over a serial cable. The Bios CFE (stands for Common Firmware Environment) is developed and offered by Broadcom. The interaction is done by a GUI, or by the Command-Line (CLI).

Requirements

The requirements to access the BIOS are:

  • Program for serial communication (e.g. PuTTY)
  • USB ↔ Mini USB cable
  • Installed USB / UART drivers under Windows

Set up serial connection

  1. Set up serial connection with the Box e.g. via PuTTY.
  2. Switch on the Dreambox while keep pushing the button.
  3. The BIOS should appear automatically after a few seconds.

CLI Modus

The following output shows the start of the Dreambox in the BIOS / CFE Mode.
