Hi Everyone! A friend of mine has conducted some experiments with the flashrom
in his ti89 in order to find out how to patch the OS.
Here you can read about his experiments:

TI has obviusly gone through a lot of hard work preventing calc programmers to
be able to write to the flash witout using TI's own routines (that only work in
the Archive Area of the flashrom) that can't be used for patching the OS.
Read it, it's quite interesting.
