Hi,
    I tried to install QNX 4.25 ( 2011 CD ) in VirtualBox 4.2.* ( 4.2.6 recently ), Win7 64bit host . Installation 
always failed during autodetecting hardware phase ( window of QNX Installer 2011 disappeared from screen ). I found 
solution:
- run installation in diagnostic mode / F12
- deselect PCI BIOS, SCSI controllers, network cards (ethernet, arcnet, token ring, ... )
With these settings QNX installation was successfull.

Just want to ask: is there any option in virtual machine which can cause smooth installation of QNX?
( i used default HW settings of virtual machine, disable audio, use INTEL PRO/1000 T Server network card )
