So I'm just thinking out loud here and trying to see a bigger picture of what things will look like if/when this is all done.
1. The dash hack that most everyone here loads up normally (I'll take bert & ernie as an example) will boot off the xbox hdd via default.xbe launching the Signed EvoX V1.8.3752 Dashboard.
2. From the bert&ernie evox menu, you would launch the "Phoenix Bios Loader" program (another default.xbe) which will start the app.
3. The app starts, and emulates booting up the xbox for the first time and loads the X2 4977 bios which in turn launches evoxdash.xbe (as if a modchip was installed)
4. From here, you have all the benefits of a modchip or flashed TSOP running the 4977 bios. Which means you can run any unsigned app, game, etc from the xbox hdd...
WOW! Now this is impressive!!!
Now that I think more about it, maybe I should have used the complex loader! to choose to boot the Phoenix Bios Loader....
