Please provide some information about the hard- and software used.
Box type: DB7025
GUI (enigma1/enigma2): Enigma2
Firmware version: Latest DMM build as of 06022006
your question Is there a tutorial on how to build a multi boot environment? I'd like to have a Compact Flash in my DB and be able to boot with different images to try out various things, but keep the original DMM image intact as a reference. I searched the board, but maybe I have missed it.
