The goal was to start a machine from scratch, using that DVD because it was the only thing available. Why would it matter if the GPU is accelerated or not? What relevance has the AirPort Extreme here?

The 5.1 machine is still on 10.6 at the moment, feel free to ask me to check whatever you would like me to check. The GPU is HD 5770. It works fine, in my opinion.
hello ,how i can install 10.6 from scratch on my mac pro 2,1 ....can you helpme
 
It seems you do have a computer, though? Download the ISO, burn it to a DVD, boot with this DVD. If you want to open the DVD, power on the computer while holding down the right mouse button until DVD tray opens.
