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.
