Looking over some articles on the Net about XBox, it seems that Microsoft has taken the same "off-the-shelf" parts that are used to build a "Wintel" clone PC. In particular, hardware site HardOCP opened up their XBox and found very PC-like guts inside: http://www.hardocp.com/articles/xbox/index.html That's an Intel CPU (733MHz Mobile Celeron?) and motherboard, an nVidia video chipset, a hard disk, a DVD-ROM, and 128MB of RAM. Given that you can't build an equivalent PC for $299, I wouldn't be surprised if someone's out there trying to get one of these things to boot a full version of DOS and/or Windows. Is the XBox really just an Intel-based PC running dedicated video game console firmware, or is its architecture 100% different from a clone desktop?
