2. Install HW3Patch 1.03 (compatible with any AMS 2.00 - 3.10 and HW Version 3 and 4 - TI89 Titanium);
Note: Be sure it is not installed yet. If it is so see footnote (1).
3. Install KerNo 3.1
Note: I suggest to use this Kernel. Be sure it is not installed yet. If it is so see footnote (1).

If HW3Patch or KerNo during installation report this kind of message: 'Installed yet', you have to do a Hardware Reset (using the Reset button on the backpane inside the Battery dock). Be carefull - All current data (home, archived and flash apps, the time settings)on TI-89 will be lost. I will be not responsabile for this!

Note(2) TI-89 'Titanium'.
Cstr1.3.1 is under testing with TI-89 'Titanium'. It features even a new installer, new Auto Load&Save features and more. Try it!

FAQ

Q:Why Executing first and Archiving?
A: Executing a func or a prgm before archiving it permits the AMS to save it in a format that speed up the execution of the prgm or func itself.
