the bios is what allows you to ftp the xbox. You need to create a boot disk. Check the guides for seamonkey guides. It will walk you through step by step.
scottas when you're not sure about what you're saying then be careful, you could lead someone to do stupid shit (not in this case). The DASHBOARD is what allows you to ftp to the xbox... the BIOS is what unlocks the xbox to run backuped games or programs like the DASHBOARD or XBMC.
I know, I know, dumb post. Should have gone into more detail. The Bios allows the installation of a new dashboard, which allows the ftp process. Thanks for the catch all. I'll make sure I sleep some before posting in a coma state. (lack of sleep)
