Intel(R) 82801FBM LPC Interface Controller - 2641 Driver

The Intel(R) 82801FBM LPC Interface Controller – 2641 driver helps Windows identify the LPC interface in Intel’s ICH6-M chipset and apply the appropriate device configuration. It is intended for compatible older laptops, especially after reinstalling Windows or when Device Manager lists an unidentified chipset component. Although listed under Storage, this controller supports low-speed legacy system interfaces rather than acting as a dedicated disk controller.

Key Features

• Correct device identification: Intel chipset INF information helps Windows display the controller’s proper name instead of a generic or unknown device entry.
• Chipset configuration support: Provides device information that Windows uses to associate the controller with the appropriate built-in system support.
• Legacy platform coverage: Suitable packages may be available for Windows XP, Vista, 7, 8.1, and 10; compatibility depends on the specific computer and package.
• Reinstallation assistance: Helps restore accurate chipset identification after a clean installation, without requiring unnecessary third-party driver utilities.

How to Install Intel(R) 82801FBM LPC Interface Controller – 2641 Driver

1. Confirm your hardware. Open Device Manager, locate the controller or unidentified system device, and check Properties > Details > Hardware Ids. Look for Intel vendor ID VEN_8086 and device ID DEV_2641.
2. Choose a compatible package. Before starting an Intel(R) 82801FBM LPC Interface Controller – 2641 driver download for Windows, verify your Windows version, system architecture, and laptop model. Prefer your computer manufacturer’s chipset package or an appropriate Intel release.
3. Download and prepare. Select a trusted free download and extract the archive if needed. The latest version is only useful if it explicitly supports your hardware and operating system. Create a restore point before making changes.
4. Install the chipset information. Run the supplied installer and follow its prompts. If the package provides INF files for manual installation, use Device Manager > Update driver > Browse my computer for drivers and select the extracted folder.
5. Restart and verify. Restart if prompted, then check Device Manager for the correct controller name and any remaining warning icons. If installation fails, recheck compatibility rather than forcing an unsupported package.

Keep the driver information updated when a compatible release addresses a specific issue or your computer manufacturer recommends an update. For Windows 10/11, do not assume that this legacy chipset has modern support: Windows 10 compatibility requires verification, and Windows 11 support is not established. A correctly identified, working controller generally does not need repeated driver changes.
