Hi Steve,

It seems that your hardware is quite modern and its main working mode is UEFI/APIC. But QNX 4.25 does not support APIC. 
Many modern hardware configurations have legacy mode fallback, but most of them are bad-configured and use the same IRQ 
for most devices.

There is no siple solution if it's available at all. You can try to play with BIOS settings. Or try to use another BIOS 
firmware (may be old one). But it’s on your own responsibility.

Respectfully,
Oleg
