I've never used Haiku so far; upon reading this I decided to try it on
my NetBSD-current laptop with nvmm.

So far, with several attempts, it works with no problem whatsoever,
directly booting the newest image on the site pointed above.

Another OS to play with...

The host cpu is Intel(R) Core(TM) i7-3820QM CPU @ 2.70GHz, id 0x306a9.
