When a Nspire starts:
- The boot1 launches the boot2, if the boot2 is valid.
- The boot2 launches the OS, if the OS is valid.
In
this topic, a modified boot1 was invented, which allowed to launch any boot2 on TI-Nspire ClickPad Hardware Revision A or earlier, or prototypes Nspire ClickPad, after a slight hardware change.
Thus was created the boot1 1.1.9999.
Tonight, after a few days of research
from scratch, Benoit Anastay, looking to start hacking his Nspire, has successfully continued this work:
A boot2 which doesn't check the OSes ! !So tonight we have pictures of his Nspire ClickPad (basic) with a CAS OS installed without Ndless!
We can see the boot code numbers:
boot1 1.1.9999
boot2 1.4.9999 (number chosen to keep a certain logic)
The patch for the boot2.img will be published very soon, the time to write a readme and that someone else makes this manipulation with success.
Congratulations to Benoit who made this in 3 days from scratch !
Thanks for this !
