I've a couple of spare Zotac zbox hd-id11 boxes, so wouldn't mind putting snow leopard on one of them, i've tried with a hazard distribution, and allthough it looked like it installed, it wouldn't boot.

I've since searched and found the following in a post on another board

Install retail + combo 10.6.7
DSDT + FAKESMC + legacy

Proc = Intel® Atom D510 (Pake Kernel Atom) - Work
Graphic = NVIDIA ION (QE/CI) - Work
Sound = RealtekHDA (VoodoHDA) - Work
Card Reader = Work
Wi-Fi = Atheros AR9285 (AirPort Extreme) - Work
Ethernet = RealtekRTL8111/8168B (pake lnx2mac) - Work
64-bit = Work

Unfortunately I'm not entirely sure what this means, could some one point me in the right direction.
