Thanks seanb,

I ran into apic-startup  problem. I have to solve that problem before I install py3.
I have installed QNX 6.5.0 on an Advantech PCI-6880 PCI board. This board uses chipsets: Intel 855GME + 6300ESB. I have 
 applied patch-650-2338-RS3775_x86-650-updates, still the startup-apic problem manifests itself on  this board on  boot-
up about 50% time. New patch does not fix the apic problem for my board.
This board has no problem with QNX 6.3.2 and 6.4.0.

I have posted the same on different discussion group.

Hi Seanb,

I want to install py2.7, py2.7_ctypes, py2.7_web on QNX 6.4.1 but these binaries doesn't exist under head_6.4. Can I use
 the binaries under 6.5 for 6.4.

Thanks
Sudhir
