Xeon(R) processor E3-1200 v2/3rd Gen Core processor PCI Express Root Port - 0155 Driver

The Xeon(R) processor E3-1200 v2/3rd Gen Core processor PCI Express Root Port – 0155 driver helps Windows identify and configure this Intel PCI Express root port, which connects the processor to compatible PCIe hardware. It is relevant when rebuilding an older Intel-based PC, reinstalling Windows, or investigating an unrecognized system device in Device Manager. Although listed under Storage, this component is part of the platform’s PCIe infrastructure rather than a dedicated disk controller.

Key Features

• Provides device identification and configuration information so Windows can recognize the Intel root port correctly.
• Supports the platform connection used by compatible PCIe expansion hardware; attached devices may require separate drivers.
• Helps resolve missing device names or identification issues after a Windows installation when the correct chipset package is applied.
• May be supplied through an Intel chipset INF package, which describes hardware to Windows rather than replacing its built-in PCIe driver.

How to Install Xeon(R) processor E3-1200 v2/3rd Gen Core processor PCI Express Root Port – 0155 Driver

1. Open Device Manager and locate the root port under System devices or check unidentified entries under Other devices. In Properties > Details > Hardware Ids, confirm that the device identifier includes `VEN_8086&DEV_0155`.
2. Check your Windows edition and whether it is 32-bit or 64-bit. Listed operating systems include Windows 10, 8.1, 7, Vista, and XP, but each package may support only some of them. For Windows 10/11 systems, verify compatibility explicitly; Windows 11 support is not established by this listing.
3. Before choosing a Xeon(R) processor E3-1200 v2/3rd Gen Core processor PCI Express Root Port – 0155 driver download for Windows, compare the package’s supported hardware and operating systems. Choose a trusted manufacturer source for a free download, and select the latest version compatible with your specific computer.
4. Extract the package if necessary and run its setup utility. If manual installation is supported, use Device Manager > Update driver > Browse my computer for drivers, then select the extracted folder.
5. Restart if prompted, then check Device Manager for warnings. If installation fails, confirm compatibility instead of forcing an unsupported package.

Keep this driver updated when your computer manufacturer recommends an update or when a compatible release addresses a documented issue. A newer chipset package does not automatically improve storage speed or PCIe performance; prioritize the correct hardware match and stable operation.
