Winter all ready got this advice on team-xecuter's forums, but I will post it here as well in case the same question comes up later from someone else.
OBCD is right in that the booting to dash/bios is a setting that needs to be changed. The X3 Config Live bios defaults to booting back to itself. You have to go into the settings and disable the feature, then when you reboot it will follow your identified boot paths (also defined in the config live settings), and if you ever did want to get back into the bios, you would boot while holding white.
As for the network settings, I really don't know why that is. I was thinking that maybe there was a save button, you might need to press, but after looking at my machine I didn't see a save, so i am not sure what to do about that. Sorry.
I dont have time right now to grab the lnk, but if you google "X3 Busted Chain", you will find the link to his awesome x3 bios guide.
