Intel(R) 5520/5500/X58 I/O Hub to ESI Port - 3406 Driver

The Intel(R) 5520/5500/X58 I/O Hub to ESI Port – 3406 driver helps Windows identify the Intel chipset component that connects the I/O hub to the platform’s I/O controller hub. It is relevant to compatible workstations, servers, and desktop systems using Intel 5520, 5500, or X58 chipsets, particularly after reinstalling Windows or finding an unrecognized system device in Device Manager. Although listed under Storage, this component is part of the chipset infrastructure rather than a standalone disk controller.

Key Features

• Correct device identification: Intel chipset INF files help Windows display the appropriate device name and associate the component with the relevant system configuration.
• Platform-specific setup: Intended for systems containing this particular Intel I/O hub interface, not every computer with an Intel processor.
• Legacy Windows compatibility: Listed operating systems include Windows 10, 8.1, 7, Vista, and XP; check the individual package for supported editions and architectures.
• Support for clean installations: Can resolve missing chipset identification after an operating system installation, though it does not replace separate SATA, RAID, or storage-controller drivers.

How to Install Intel(R) 5520/5500/X58 I/O Hub to ESI Port – 3406 Driver

1. Verify the device. Open Device Manager, locate the relevant system device or unknown device, and check its hardware IDs under Properties > Details. Confirm that the package supports your hardware.
2. Check operating system compatibility. Before choosing an Intel(R) 5520/5500/X58 I/O Hub to ESI Port – 3406 driver download for Windows, confirm your Windows version and whether it is 32-bit or 64-bit. For Windows 10/11 systems, do not assume Windows 10 compatibility guarantees Windows 11 support.
3. Choose a trusted package. Prefer your computer or motherboard manufacturer’s recommended chipset package, or an applicable Intel release. A free download should still have a verifiable source and compatible driver information.
4. Install the chipset information. Extract the download if necessary and run its setup utility. If the package provides only INF files, use Device Manager’s Update driver option and browse to the extracted folder.
5. Restart and verify. Restart if prompted, then check Device Manager for the correct device name and any remaining warning icons.

Keep the driver configuration current by checking for an applicable update when troubleshooting or reinstalling Windows. The latest version is useful only if it supports your hardware and operating system; a newer chipset package may not include this older platform. Chipset INF updates primarily improve identification and configuration, not storage speed.
