Hi,
You sound like I felt about a month ago
Like stacker said, you need to get hold of another bios to do the real fun stuff on a chipped xbox.
http://www.teamxodus.com/modules.php?name=...download&cid=13Have a look at the link above and in particular the Iceguide link. As you've done the hardware install, start reading from 'Setting up the original BIOS'.
Basically you need to add an entry in the ice config so that you can boot into the original MS bios. Fairly straightforward.
Then you need to get hold of one of the other bioses, I would recommend the X2 4983 (unless you have a 1.6 xbox then you'll need the M8 1.6 version).
I find
http://www.macsat.com useful for IRC access, as it has a web front end so you dont need to install any irc client. You will need some form of FTP client tho.
Whilst you're there, get a dashboard (evolutionx?) and xboxmediacentre
Then you need to get all the files onto your xbox. The easiest way is to ftp them from your pc to the xbox. This will involve setting up the networking on the xenium which i'll assume you can do or find info on how to do unless you ask
. It's covered in the guide i think.
Stick the x2 bios (just the 256k .bin file) on the root of the c:\ drive (use the .06 version unless youve got a really big hard drive in your xbox). Then you can go and read the bit in the PDF about setting up an additional bios. Also set this bios to be the default. You might want to auto boot this bios so you dont have to keep selecting it in the xenium menus. You can always get back to the xenium menus by powering the xbox on with the eject button.
Next install the dash which you need to be able to run the mediacentre etc. This is also covered in the guide i think. It basically involves copying the evoxdash.xbe and evox.ini files and the Skin directory to the root of the c:\ drive. You may need to edit evox.ini to tweak the network settings to suit your network, but it will run without editing.
(I dont think you strictly need a dash to play backups but I installed it anyway and havent tried it without one)
Thats basically it, you should be able to run a backup now. Everything else should just be finetuning of network settings, menu items etc.
This is all from memory of my experience with a 1.0 xbox (standard hard disk) and an ice, so may not be totally correct for your setup.
I dont have live, but if you do you should read up about how not to get banned Have fun and try xboxmediacenter as it rocks!
