That is a less than complete EvoX ini file, if any of those items were selectable options you wouldn't want them. It would flash your chip back to an old BIOS.
Do you have any idea what your dashboard was before your 2.3 fried? Does EvoX look familar? (As far as I've seen EvoX always has options in the lower middle of the screen, a scrolling list of text options.) There was an option to set the box to boot Avalaunch in that ini, is that possibly what you were using?
The next thing you should probably do is get the evox.ini file straightened out. For this I would recommend obtaining a default evox.ini file that is packaged with the dashboard. You can find EvoX on xbins, a tutorial is here-
http://www.xbox-scene.com/articles/xbins.php When you get the file take the time and read through it before putting it on your xbox. You may need to make some changes, like network settings. There is a lot of text in there that explains what the different options are.
x2config.ini needs to go in the root of E or F, but leave it where it is for now. Since you are at least able to get into your xbox with FTP right now we don't want to goof that.
Also, you've got a PM in your account. Check under where it says "welcome, thedba" at the top of your screen.
