Install PalmOS 4.x on Zire31

Archived from groups: comp.sys.palmtops.pilot (More info?)

Hi all,

I bought a zire 31 palmone with palm OS 5.x.x
But i need to put a palm OS 4.x.x for a home-made application of my
company.
If someone's got an idea to help me !!!!

For information, the application that need palmOS 4 to work is made
for managing an automated chain via infra-red.

So i think there are 2 possibilities:
- Install palm OS4.x.x
- Emulate OS 4 on a OS5 (but if it existe it must support IR)

Thanks for all your answers

Vincent

besides that, the Zire's do not have flash ROM they have Masked ROM and
can not be up/down graded.
