What is System Interrupt Controller

Specs: Win XP Pro SP2, AMD Athlon64 3500+ 2GB RA
I have an ASUS A8N-E SE motherboard. I've installed all the drivers from the drivers disk but I still get a message saying I haven't installed drivers for a "System Interrupt Controller". I can't find anything on the drivers disk for that. What is a System Interrupt Controller? My computer still works fine without it.

if this driver doesn't work and your system is running fine without it, look in the bios for 'APIC' and disable it.

APIC mode (Advanced Programmable Interrupt Controller) is a BIOS setting made available to Windows 2000 and Windows XP systems that increases the number of IRQ (Interrupt Request) lines available to the processor.

When APIC is disabled in a Windows 2000/XP system, only 16 IRQs (0 to 15) are available to the processor, as is the case with Windows 9.x systems, instead of the 23 that are available with this setting enabled. This reduces the amount of hardware that can be run on the system to the level of Windows 9.x system.

still, you should contact your mobo manufacturer's tech support for the correct driver in case of future system upgrades and hardware add-on.

I downloaded the driver you told me to and it didn't work (said my PC doesn't have a supported AMD System Interrupt Controller). I then disabled APIC and WindowsXP wouldn't boot so I had to re-enable it.
