QNX 6.3 doesn't work on ASUS P5GD2 motherboard

I try to install QNX 6.3 on a PC with ASUS P5GD2 motherboard. Installation CD (which works fine on other computers) displays about 10 the same messages

Unable to allocate resource: Invalid Argument


/dev/pci not found

and stops :frowning: . QNX4.25 works in that PC, however.
Any ideas?

Have you tried to disable DMA? Also make sure Plug and Play OS in the BIOS is off. Further turn off Legacy USB support.

I’ve already tried this but useless. It seems me that PCI scan (pci-bios) fails, possible due to PCI-Express features. But I haven’t found any BIOS settings to change PCI behavior.
