Advanced Programmable Interrupt Controller driver is a windows driver. Common questions for Advanced Programmable Interrupt Controller driver Q: Where can I download the Advanced Programmable Interrupt Controller driver's driver? Advanced Programming Interrupt Controller. Advanced Programmable Interrupt Controller by Mike Rieker. Though I had originally wrote my APIC code over a year ago, I've been playing with it recently, so I thought I'd write about it. When the IOAPIC receives an interrupt from a controller card, it forwards the interrupt out to the LAPIC's (as. ![]() Updated: by Computer Hope Short for Advanced Programmable Interrupt Controller, APIC is a PIC (programmable interrupt controller) with advanced interrupt management. It was first developed by and replaces the 8259 interrupt controllers. APIC is necessary for dual processing or multiple-processor support and has been available since the original Intel Pentium. However, the motherboard,, and operating system (Windows 2000 and later) must also support APIC before it can be used. Although APIC adds support for multiple processors, it is still used with single-processor computers since it provides support for virtual PCI IRQs above 15. Windows XP is one of the first versions of Windows that takes full advantage of APIC if enabled and assigns more devices to IRQs above 15. Note: Windows XP Professional x64 edition and Windows Server 2003 for cannot be installed unless APIC is enabled in the system BIOS. AMD attempted to develop a competing technology, named OpenPIC, but it was never used with any motherboards. Ended up licensing APIC for use with their Athlon and later processors.,,. A ACPI Advanced Configuration and Power Interface, an industry specification for BIOS and hardware extensions to configure PC hardware and perform power management. Windows 2000 and later, as well as Linux 2.4 and later support ACPI. Windows can only enable or disable ACPI support at installation time. AHCI Advanced Host Controller Interface, the interface that supports SATA devices such as hard disks. AMD-V The hardware virtualization features built into modern AMD processors. API Application Programming Interface. APIC Advanced Programmable Interrupt Controller, a newer version of the original PC PIC (programmable interrupt controller). Programmable Interrupt Controller DriverMost modern CPUs contain an on-chip APIC, called a local APIC. Many systems also contain an I/O APIC (input output APIC) as a separate chip which provides more than 16 IRQs. Windows 2000 and later use a different kernel if they detect an I/O APIC during installation. Therefore, an I/O APIC must not be removed after installation. ATA Advanced Technology Attachment, an industry standard for hard disk interfaces which is synonymous with IDE.
