Intel 82801EB LPC Interface Controller 24D0 Driver

The Intel 82801EB LPC Interface Controller 24D0 driver helps Windows identify and configure the LPC interface on Intel 82801EB-based motherboards. It is intended for users reinstalling Windows or investigating an unrecognized chipset device in Device Manager. Although sometimes listed under Audio, this controller is a chipset component—not a sound device—and its driver will not replace your audio driver.

Key Features

• Correct device identification: Chipset INF files help Windows display the appropriate controller name instead of a generic or unknown system device.
• Chipset configuration information: Provides information Windows uses to associate the controller with the appropriate system support.
• Legacy interface support: Helps identify the LPC bridge, which connects the chipset to low-bandwidth motherboard components.
• Reinstallation assistance: Useful when restoring an older Intel-based computer and checking that its system devices are correctly recognized.

How to Install Intel 82801EB LPC Interface Controller 24D0 Driver

1. Confirm the hardware. Open Device Manager, locate the controller or unidentified device, and check Properties > Details > Hardware Ids. Look for the Intel vendor and device identifiers `VEN_8086&DEV_24D0`.
2. Check operating system compatibility. Before choosing an Intel 82801EB LPC Interface Controller 24D0 driver download for Windows, verify support for your exact Windows edition and architecture. Listings for Windows 11, 10, 8, or 7 do not establish compatibility; this older chipset may lack official support on newer systems, particularly Windows 10/11.
3. Choose a trusted package. Look for a free download from your computer or motherboard manufacturer, or an applicable Intel chipset package. Select the latest version explicitly compatible with your hardware and operating system rather than assuming the newest package supports older chipsets.
4. Install the driver information. Run the package’s installer and follow its instructions. If the package provides extracted INF files and supports manual installation, use Device Manager > Update driver > Browse my computer for drivers, then select the extracted folder.
5. Restart and verify. Restart if prompted, then check Device Manager for the controller’s identification and any remaining warnings. If installation fails, do not force an incompatible driver.

Keep the driver updated when a compatible update addresses a documented issue or improves system support. If the controller is already recognized and working correctly, a newer chipset INF package may offer no practical benefit. For missing sound, check the separate audio controller and its driver instead.

Common Issues and Fixes

• Install fails or rolls back: Newer Intel Chipset Device Software packages may omit ICH5/82801EB support. Use a legacy INF Update Utility that lists `PCIVEN_8086&DEV_24D0`, or update manually in Device Manager via “Have Disk” and select the matching INF.
• Device not detected / yellow mark: Confirm the LPC bridge is enabled in BIOS and appears with hardware ID `PCIVEN_8086&DEV_24D0`. If Windows shows “Unknown device,” install the Intel chipset INF instead of a generic PCI-to-ISA driver.
• Version conflict or wrong driver: Remove any forced generic/ISA bridge driver, roll back, then reinstall the Intel INF matching the chipset. Avoid Intel Driver & Support Assistant for this legacy controller; it may offer packages that do not support 24D0.
