Live QNX !!

Someone know where I can find a QNX Live version?? (I don´t speak english, excuse me for my poor language)

What do you mean by ‘live’ version? You can download an eval version here:
qnx.com/products/eval/index.html
What you get is QNX Momentics (the tools for QNX).
Be careful: If you don’t use a BSP (non-x86), and want the OS for x86, you have to download Momentics on the ‘Neutrino’ host, and you get the Neutrino OS as a side effect. Burn a CD with that image and boot it on a not-too-new PC (or switch Serial-ATA to Compatible/P-ATA in BIOS).

Thks…I try…
