Backup games Via HD

[devilchild]

I have a completely unmodded xbox, I have a pc with a network card, and crossover adapter. I'm tempted to start soldering, never done it before. But i consider myself technically minded. But first i was wondering. Is it possible to transfer backups from the pc harddrive to the xbox harddrive and run them?

I'm guessing i will need an updated bios, Is it not possible to get an updated bios without having the xbox modded?

I've looked around the forums, I dont want to softmod, as its not a definate answer. I dont want to get a solderless chip, as these from reading some posts here seem to be damaging internal components? I may solder, But im in experienced. So if the way i'm asking about works. I'd like to try it. Does it work?

If not, Are solderless chips safe?

If not, Whats the easiest solder chip?
