Device drivers are the software interfaces that talk directly to the physical system hardware. The PCI\VEN Code can be broken down into parts that relate to the hardware manufacturer, the category of the hardware and the revision of the hardware. The first part, the "PCI\VEN_", is specific to the manufacturer, Intel® has the PCI\VEN code of "PCI\VEN_8086". The "&DEV_" part of the code relates to the hardware, in this case the "DEV_277C" relates to system hardware, specifically the 82975X Memory Controller Hub. If the system device is slow or just seems to be not working, then it is likely that the driver is a generic driver, is not installed correctly or is just broken. For use only with the Intel® 82975X Memory Controller Hub device, an up-to-date list of downloads is shown below.
