Evo,
You cannot compare a notebook computer to a desktop. With a notebook, everything is on the motherboard, either in the northbridge or the southbridge. So you would see a lot of devices all on the same IRQ. A desktop is difference, since it has a full PCI Bus.
(With a notebook computer, every component is tested for compatibility when the notebook is in the design phase. With a desktop, there are an infinite amount of combinations due to all the hardware available out there for it. All hardware has its own unique needs. The trick is know what they are. That is not always easy.)
Keef,
Before you do the install again. Please list the make and model of the motherboard. If the computer is from a major computer maker, then the make and model of the computer. (From there I can pull the information I need.)
Do not confuse
APIC (Advanced Programmable Interrupt Controller) with
ACPI (Advanced Configuration and Power Interface).
Take Care,
Richard
