Compaq notebook installation

I tried to install QNX 6.2 on a P2/300 Notebook from Compaq. It is a
Armada 1700.
Everything looks fine, all the files were copied, but when I restart my
computer after the installation process, the notebook hangs during the
startup procedure.
I tried to start without DMA but had also no success.
Does anybody have an idea how to get this running?
Thanks for your help!

Sorry! Made a mistake during installation procedure. RTP 6.2 works fin
with that laptop!
