On March 20, 2007, it was announced that a hack using the previously discovered hypervisor vulnerability in the Xbox 360 kernel versions 4532 and 4548 had been developed to allow users to run XeLL, a Linux bootloader. The initial hack was beyond the average user and required an Xbox serial cable to be installed and a flashed DVD Drive firmware. Felix Domke, the programmer behind XeLL, has since announced a live bootable Linux CD suitable for novice users, with the capabilities to be installed to the SATA hard drive of the Xbox 360. Despite the availability of such a distribution, the Xbox 360 still isn't considered a popular platform for homebrew development, given the dependence of the exploit on the DVD-ROM being able to load a burnt DVD |game, a modified version of the game "King Kong", and two older kernel revisions of the console itself.
