Hi: IRQ's, or Interrupt Requests, are numbered signals sent to the CPU to tell it that a particular Peripheral Component Interconnect (PCI), such as your mouse, keyboard, a port, a hard drive, etc., needs attention The IRQ Holder for PCI Steering means that Windows is "holding" or reserving an IRQ for PCI devices, which can share IRQ's, and "steering" the IRQ to whatever device needs it Older ISA (Industry Standard Architecture) peripheral devices each need their own IRQ.

If you go to, click on support, then click on knowledge base, you will find two excellent articles, numbers Q182604 and Q182628 that give a description of PCI Bus IRQ Steering, and show step-by-step how to disable it, which may be what the error message is telling you to do Good luck!
