PCI Standard Host CPU Bridge Windows Driver: Overview

The PCI Standard Host CPU Bridge is a type of hardware driver in Windows that allows the operating system to interface with the host CPU and manage communication with other system components like the PCI (Peripheral Component Interconnect) bus. The PCI bus connects various peripherals, such as graphics cards, network adapters, and storage devices, to the CPU. The "host CPU bridge" refers to the controller that acts as an intermediary between the CPU and the PCI bus.

This driver is typically installed automatically when you install Windows or when you install a motherboard chipset driver package. It's primarily used for systems with older chipsets or specific configurations where a separate bridge component is needed.
