Intel H67 Express Chipset Family LPC Interface Controller 1C4A Driver

The Intel H67 Express Chipset Family LPC Interface Controller 1C4A driver helps Windows identify the Intel H67 chipset’s Low Pin Count (LPC) interface controller and apply the appropriate device configuration. It is relevant if you have an H67-based motherboard and Device Manager shows an unidentified controller or missing chipset information after a Windows installation. Although sometimes listed under Audio, this device is a chipset component—not a sound controller—and its driver does not replace your audio driver.

Key Features

• Correct device identification: Intel chipset INF information helps Windows display the controller’s proper name instead of a generic or unknown device label.
• Chipset configuration support: Supplies identification and setup information for the LPC interface, which connects the chipset to certain low-bandwidth system components.
• Useful after reinstalling Windows: Can resolve missing chipset identification when the installed package matches your motherboard and operating system.
• Hardware-specific matching: The device identifier 1C4A helps distinguish this Intel controller from other chipset components and avoid unrelated packages.

How to Install Intel H67 Express Chipset Family LPC Interface Controller 1C4A Driver

1. Verify your hardware. Open Device Manager, locate the controller, and check Properties > Details > Hardware Ids. Look for Intel vendor ID VEN_8086 and device ID DEV_1C4A.
2. Check operating system compatibility. Before choosing an Intel H67 Express Chipset Family LPC Interface Controller 1C4A driver download for Windows, confirm that the package supports your Windows edition and architecture. For Windows 11, 10, 8, or 7, rely on the package documentation rather than assuming universal support.
3. Obtain the correct package. Prefer your motherboard manufacturer’s support resources or Intel’s official resources when available. Choose the latest version compatible with your system; a free download should not require a paid driver-updater subscription.
4. Install the chipset information package. Extract the archive if necessary, run the included installer, and follow its instructions. If only INF files are provided, use Device Manager > Update driver > Browse my computer for drivers.
5. Restart and verify. Reboot if prompted, then check that the controller is correctly identified and has no warning icon. On Windows 10/11, note that installing chipset information does not establish official platform compatibility.

Keep this driver information updated when a compatible update addresses a documented issue or is recommended for your motherboard. Newer is not automatically better for older H67 hardware, and chipset INF updates generally do not improve audio quality or increase performance.

Common Issues and Fixes

• Install fails or rolls back: The Intel INF package may not match your Windows version or device ID. Confirm Device Manager shows `PCIVEN_8086&DEV_1C4A`, then install the Intel Chipset Device Software/INF Update for H67 as administrator; if setup still fails, update the driver manually via Have Disk.
• Device not detected / unknown device: Check BIOS for disabled chipset/LPC or legacy support settings, and install the H67 chipset INF before other drivers. In Device Manager, scan for hardware changes and verify no yellow warning icon remains.
• Version conflicts: Older Intel INF or Windows generic drivers can override the correct LPC entry. Uninstall conflicting chipset INF entries, reboot, then reinstall the H67 package and avoid third-party driver updaters.
