Fair Qs.

The initial operating system user interface (UI) installed on the XBOX Hard Disk Drive (HDD) is known as the "Dashboard". When this XBOX is powered up without any DVD media in the drive, the BIOS runs C:\xboxdash.xbe, the XBOX's
boot Dashboard program. The Dashboard program allows the user to perform various housekeeping functions, tidying up game saves, copying CD audio tracks to the XBOX hard disk for use in in-game custom soundtracks, etc. The Dashboard also allows audio CDs to be played, and, with the DVD dongle, DVD movies to be viewed.
When M$ release XBOX!Live, they then required the user to have access to a whole new set of maintenance options, to configure their XBOXs for the Internet, create their GamerTag, view XBOX!Live hi scores, locate other XBOX!Live players, etc. They
could have simply released a fatter Dashboard, but, presumably, to keep memory low, and because not every one will be using XBOX!Live, they opted to put these options in a separate program I refer to as the XBOX!Live console. It is a physically separate XBE on the HDD called C:\xodash\xonlinedash.xbe.
To provide a why of launching the XBOX!Live console, they simply added a menu option to the boot Dashboard that allows the user to execute the XBOX!Live console.
