That link gives you an image that you download to your computer then fastboot flash once the phone is S-Off.
As I say, there is an app (actually 2 apps) which is linked earlier in the post, but you'll need to be rooted first to use that. That is the alternative - just accept revolutionary's recovery, root, then install the app and use that to replace the recovery. But I figure why not just install 4Ext from the start - it's much better than the recovery revolutionary will give you.
