Kernel Debug
From xboxdevwiki
Only enabled in debug kernels, a Xbox with serial port can be kernel debugged with windbg. only executables that have debugging switched on can be debugged over serial aswell(?) [citation needed] {FIXME| Explain with more details ;) }
Xqemu emulates this serial port, wich uses a [[Super_I/O | LPC chip ].
{FIXME| some example kernel output}
