Windows Very light on details, but this is interesting nonetheless - very interesting, and potentially one of the biggest things to have hit the operating systems business this decade. Bloomberg is reporting that Microsoft plans to announce Windows for ARM processors at CES in January 2011.

Kernel is portable

So, NT's roots lie in portability, but how much of those roots are left remains to be seen.


Well a fairly recent NT kernel currently runs on a PowerPC core in the XBox 360, so it seems Microsoft have been quite careful to maintain that portability over the years.

You're confused. The original Xbox is x86. The 360 is PowerPC, but doesn't use any NT code as far as I know (it's entirely custom).

My understanding is that it runs a heavily modified NT 5 kernel.

Anyway, Windows Server 2008 R2 runs on Itanium, so it's a better, more recent example. IIRC, Windows needs a CPU capable of running in little-endian mode, but that's the main restriction.

The 360 runs a modified NT kernel.

Yes, I remember a fellow classmate who was perfectly happy running NT4 on aplha. The Poor Bastard.
