Hello Ronron, I would need to inform you that IRQ settings cannot be changed in the system BIO, IRQ's are designated by the operating system.
In the BIOS you may set IRQ priority; however, the operating system will override the BIOS settings and reset the IRQ's.
If you wish to assign the IRQ's manually, we would recommend contacting the Operating System Developer for assistance.
Thank you, sylvia for your quick response.
In fact, I do not have a conflict between my video aquisition card and my USB port (they are shared IRQ). I wanted to move the IRQ of my USB port on my motherboard intel card to a number more top 5 or 6. I'm afraid if I move the IRQ of my card aquistion, my software does not work .
The aim here is to virtualize a production unit by the VT-d (hardware virtualization).
I am under linux, you can can I move the USB IRQ? And like to do? : p
