Boot menu and add ons

Hello,

It's the first time I'm trying your great image and I have some questions that I couldn't find any answer in this forum...

1)What is the difference between enigma and enigma ext in the boot menu ? And what is IP-Service ?

2)I put all the plugins, locale, etc in /hdd (So I got some /hdd/local directory with many files and directory in it) and I cannot launch doom, I don't see any games in the game menu, the OSD is not translated in my language.

Edit: I solved this one and found the extra menu.

3)In the keys subdirectory of /hdd/local there is a sky.key, how am I supposed to use this one ?

thanks a lot,

Doing boot you should select "Enigma". As I understand it the menus have the following function:

Enigma: Runs the Enigma from RAM.
Enigma-EXT: Runs the Enigma from HD.
Service-IP: Is used for some kind of remote access/diagnostic I believe!?
Doom: Is supposed to start the game "Doom" but my DB shuts down whenever selecting this menu. It did the same with any previous versions.
