HORM is a mechanism for quickly rebooting the same XPe image any number of times, according to Moini. In this respect, it is fundamentally different from hibernation as used in laptops, where the hibernated image doesn't persist across reboots.
Moini notes that the process of activating and deactivating HORM has been simplified in Feature Pack 2007. Finally, he offers some sample code that shows how to use the HORM APIs.
