KJK::Hyperion continues "This port definitely establishes two facts: the XBox is nothing but a broken PC, and the kernel + HAL design that ReactOS inherited from Windows is sound - all of the changes to the core system necessary for the XBox port (namely, the blacklisting of a buggy PCI device and handling the fixed partition table on the built-in hard disk) were limited to the HAL. This is a first, important step towards better portability, as it has already underlined some shortcomings in our build system.
What the port is lacking is hardware support: especially, ReactOS has no USB support at the moment, so it basically just sits there being pretty, because mouse and keyboard won't work. The network and video cards should be mostly identical to their "real" counterparts, so the Windows drivers for them should work (except the video card, a modified GeForce - it's been established we need some HAL trickery to make the Windows driver load). We wouldn't mind some help :-)
To run ReactOS on the XBox you need our custom version of the Cromwell boot loader (not released yet) and the XBox HAL for for ReactOS."
