Hi Victor,

Did you try to install QNX 4 from the latest experimental Install CD? This CD can install on AHCI systems:

Legacy or AHCI, the other 2 has only AHCI. I tried insalling QNX on another machine, updating the Proc32, and changing 
the sys/boot to:

 This may be a little late but I had a similar problem a few years ago with new Dell Computers. I ended up changing the 
initial boot loader to the old original used by the install CD's. The command to change it is;
dinit -h -b -O /dev/hd0.0t77. 

The -h is for fixed disk not removeable device
The -b is for the bootloader
The -O is for the old bootloader.

Hope this helps you in the future.
