Device Manager is a component of the Microsoft Windows operating system. It allows users to view and control the hardware attached to the computer. When a piece of hardware is not working, the offending hardware is highlighted for the user to deal with. The list of hardware can be sorted by various criteria. [1] For each device, users can:
One of the major improvements the PCI Local Bus had over other I/O architectures was its configuration mechanism. In addition to the normal memory-mapped and I/O port spaces, each device function on the bus has a configuration space, which is 256 bytes long, addressable by knowing the eight-bit PCI bus, five-bit device, and three-bit function numbers for the device (commonly referred to as the ...
Peripheral Component Interconnect (PCI) [3] is a local computer bus for attaching hardware devices in a computer and is part of the PCI Local Bus standard. The PCI bus supports the functions found on a processor bus but in a standardized format that is independent of any given processor's native bus.

If a device has no PnP Expansion header, it may perform any hook in the routine at +03h, as it is a legacy card. In the initial initialization routine, as the Option ROM points to a PCI data structure (not the same as the configuration space), the option ROM code knows the device and vendor ID is at a fixed offset from RIP.
NXP devices have a higher power set of electrical characteristics than SMBus 1.0. The main difference is the current sink capability with V OL = 0.4 V. SMBus low power = 350 μA; SMBus high power = 4 mA; I²C-bus = 3 mA; SMBus ‘high power’ devices and I²C-bus devices will work together if the pull-up resistor is sized for 3 mA.
PCI Express Mini Card (also known as Mini PCI Express, Mini PCIe, Mini PCI-E, mPCIe, and PEM), based on PCI Express, is a replacement for the Mini PCI form factor. It is developed by the PCI-SIG . The host device supports both PCI Express and USB 2.0 connectivity, and each card may use either standard.
The graphics address remapping table (GART), [1] also known as the graphics aperture remapping table, [2] or graphics translation table (GTT), [3] is an I/O memory management unit (IOMMU) used by Accelerated Graphics Port (AGP) and PCI Express (PCIe) graphics cards.
