Apple Software Restore 2.06 is available through other means. If you upgraded 9.04 to 9.1 it's probably sitting in your Apple Extras or Utilities folder. If not just use TomeViewer to extract it from the main 9.1 Upgrade tome. Mine wasn't removed by 9.21 or 9.22.

There's extensive documentation on how to use & etc. on apple/support. Just plug in Apple Spftware Installer and all of the articles are linked.

FYI

Typos, typos, typos........

The last paragraph should have said that on apple/support you simply search using "Apple Software Restore" and there are three articles on the "official way" to use the utility.

The method described is the one I've heard used most often by admins in college labs to restore drives when some student trashes a drive inadvertently or intentionally.

The Steve Bombich discussion above is also quite excellent and I don't know that it deviates from Apple's suggestions, but simply makes it understandable and addresses certain concerns specific to OS X.
