Well, can you someone tell me what the "Testfir.fir" file really does?

It seems that it allow the autoexec.bin to be launched from the card, right?
But it is reversible? If I flash the original firmware after flashing the testfir.fir is will be reverted back to normal status? (So warranty still valid?)

A few days after I flashing the testfir.fir, I flash the original firmware.
But the boot flag is not back to the original status.
So I just wonder how can I undo the hack from the "testfir.fir".

In this post by rubinson (below), he mentions "rescue disk". Where do I find this rescue disk, or is that the AUTOEXEC.BIN file posted by owerlord on the initial post for this thread?

The reason that I ask is that I would like to try this hack on my XTI, but I would feel a little better about it if I knew I had some "fall back" (or rescue disk) in case of problems. THanks!

BTW, I was planning to use the instructions listed on http://chdk.wikia.com/wiki/400D , does anyone know if these are the correct current instructions as of Jan 18, 2010?

Anybody have a response on this one? How can you "reverse" the effects of testfir.fir? I've tried to reinstall the firmware but the bootable card will still boot which tells me whatever tesetfir.fir does is still on my camera. Advice?
