I faced a problem while trying to test the new release of Moblin (2.1) which is an OS primarily designed for netbooks. When trying to boot from the live image, I get an error message stating that the kernel is not supported and that I must have something called “pae” enabled, I googled around and found what “pae” is, it’s a feature in the processor and is an abbreviation for “Physical Address Extension” and here is a brief description (not quite good though) http://wiki.answers.com/Q/What_is_pae, anyway here are the steps I used to get this .img file running in my virtualbox:
- Download the .img file from the website
- Rename it to .iso
- Assign it in the storage (as a virtual ISO CD)
- Open the options for the virtual machine you’ve just created
- Click system -> Processor -> Enable PAE.
Now you can run it and continue with the live image or installation.
Enjoy :)!
Just Some Techie Notes! 
This is excellent. My error did not mention PAE. Something cryptic about the CPU and kernel. I am trying to install moblin 2.1 in a VirtualBox on OSX. Enabled PAE and I have got past that hurdle.

Now I get the boot prompt. But when I ask it to boot, it just says moblin. Nothing happens. I waited 10 minutes to see if is still stuck and it is.
