How to find out the MAC adress in the OpenFirmware

In order to do a network installation you must provide the MAC adress of the adapter you want to boot from. This information can either be found using the SMS menu or using the OpenFirmware prompt.

To show the MAC address of a specific adapter use the dev <DEVICE> .properties command.
FYI: If you are not shure about the <DEVICE> use ls to get a list of all devices in the system.
