: Specifically linked to Lenovo or HP systems (17AA is often Lenovo/HP variant), indicating a tailored OEM device.
To understand what this device is, let's break down the identifier into its constituent parts:
It manages the System Management Bus (SMBus), which handles low-speed communication between the motherboard and components like temperature sensors, fan controllers, and voltage regulators.
The string PCI\VEN_8086&DEV_8C22 corresponds to the . Vendor (VEN_8086): Intel Corporation. pci ven8086 ampdev8c22 ampsubsys309f17aa amprev04 patched
– Used to fix sleep, hotplug, or SATA mode issues.
: The Device ID identifying the specific hardware piece as the Intel 8 Series/C220 Series SMBus Controller .
The string you've provided appears to be related to a device identifier in a computer system, specifically in the context of PCI (Peripheral Component Interconnect) devices. Let's break down the components: : Specifically linked to Lenovo or HP systems
: Refers to a modified or manually forced .INF setup configuration file used to bypass operating system signature blocks or force compatibility. What is the SMBus Controller, and Why Does it Fail?
This comprehensive guide breaks down exactly what this hardware ID means, why driver conflicts happen, and how to apply the correct driver patches to fix it. Deconstructing the Hardware ID
The INF file has been modified to recognize the specific SUBSYS_309F17AA identifier. Vendor (VEN_8086): Intel Corporation
Click , navigate to the directory containing your unpacked patched files, and select the corresponding .inf file (commonly named ich8core.inf or 8series.inf ).
If you are seeing the "Patched" tag in your hardware inventory or driver packs, it refers to a modified INF file that allows the legacy driver to install on newer operating systems.
Every hardware component on a PCI bus communicates its exact identity to the operating system using a standardized string. Breaking down this specific string reveals the following technical breakdown:
