The Xbox contains a DVD Drive which can read Xbox Game Discs. For a list of drives Microsoft used in the Xbox, see Hardware Revisions.

Xbox DVD drives are dying left and right. It is not advisable to require any new software to be launched from optical media, although this can be provided as an option for those who have never upgraded their Xbox hard drives (and still have a working DVD drive...)

It is possible to replace an Xbox DVD drive with a PC DVD drive with some modification. (What kind of drives work for this?)
