Intel(R) 631xESB/6321ESB/3100 Chipset LPC Interface Controller - 2670 Driver

The Intel(R) 631xESB/6321ESB/3100 Chipset LPC Interface Controller – 2670 driver helps Windows correctly identify the chipset’s Low Pin Count (LPC) interface, which connects legacy and low-bandwidth system components. It is intended for compatible Intel-based systems that need chipset identification after a Windows reinstall or show an unrecognized LPC controller in Device Manager. Although listed in the Storage category, this component is part of the chipset infrastructure rather than a dedicated disk controller.

Key Features

• Correct device identification: Provides chipset information so Windows can display the appropriate controller name in Device Manager.
• Chipset setup support: Helps Windows associate the LPC interface with the appropriate system resources and built-in support.
• Legacy Windows compatibility: Packages may support Windows 10, 8.1, 7, Vista, and XP; check the individual download’s operating system and architecture requirements.
• Useful after reinstalling Windows: Can resolve missing chipset identification when the hardware matches the package, without requiring a separate storage-controller driver.

How to Install Intel(R) 631xESB/6321ESB/3100 Chipset LPC Interface Controller – 2670 Driver

1. Confirm your hardware. Open Device Manager, locate the LPC controller or unidentified system device, and check Properties > Details > Hardware Ids. Verify that the device ID includes `VEN_8086&DEV_2670`.
2. Check Windows compatibility. Confirm your Windows version and whether it is 32-bit or 64-bit. For Windows 10/11 systems, do not assume shared compatibility: Windows 11 is not included in the supported OS list for this device.
3. Choose the correct package. Before starting an Intel(R) 631xESB/6321ESB/3100 Chipset LPC Interface Controller – 2670 driver download for Windows, review the package’s supported hardware and release notes. Select the latest version compatible with your system, not simply the newest available package. Use a trusted free download from Intel or your computer manufacturer where available.
4. Install the driver information. Extract the files and run the included setup utility. If the package provides only INF files, use Device Manager > Update driver > Browse my computer for drivers and select the extracted folder.
5. Restart and verify. Restart if prompted, then check that Device Manager identifies the controller correctly and shows no warning icon.

Keep your chipset software updated when a compatible update addresses a specific issue or supports your Windows installation. Many LPC packages primarily supply identification information, so an update should not be expected to increase storage speed or add new hardware features.
