Further to compatible hardware you will need:
1. A working install of OS X (this may be in a virtual machine or a native install) to prepare the installer
2. A flash drive of minimum size 8GB
3. A copy of Mountain Lion
Just a question here ron... can this not be achieved on a WInbox with a suitable boot loader? Not sure how I got my initial hack up but I didn't have access ti a Mac since my iMac was dead..... Luckily I was able to salvage the HD content when I got the hack up and running...
dmg's are certainly browseable in Poweriso but don't remember if thats how I went about it... Might be worth playing with some rainy day...but it rarely rains here!
No doubt about it though.... a working install of OS X makes life a heckuva lot easier...
