[Fixing Error 16]

I have an original xbox that has the dreaded error 16. I researched fixing this many years ago and at the time seemed like too much trouble. I'm wondering if there are any new methods that don't require a second HDD to swap back and forth? From my most resent research it sounds like there might be a way to bypass the issue to fix it using a dvd?

Any help would be appreciated!

Does this disc work on an unmodded original xbox with an error 16? Trying to get my old xbox up and running without having to get a unlocked hard drive.
