Acpi — Nsc6001

| Cause | Explanation | |-------|-------------| | | Your motherboard's BIOS contains ACPI tables referencing an NSC6001 device, but Windows 10/11 no longer ships with a dedicated driver. | | Incorrect driver migration | Upgrading from Windows XP/Vista/7 to 10/11 carries over an entry for NSC6001 that no longer exists in the new OS. | | Chipset driver residue | Old Intel or VIA chipset drivers sometimes leave behind NSC references even after uninstallation. | | Virtual machine passthrough | Hyper-V or VMware passthrough of legacy PCI devices can erroneously create this ACPI entry. |

Drivers are available for Windows XP, Vista, 7, 8, 8.1, and 10. Driver Information

For most users, no. Modern laptops no longer include IR ports, and modern operating systems have largely dropped support for the IrDA protocol stack. Microsoft, for instance, removed native IrDA support starting with Windows 10. However, for enthusiasts and vintage computing hobbyists reviving an old laptop, getting the ACPI\NSC6001 driver installed is often a point of pride—a final piece of the puzzle to achieving a fully functional retro machine. It may also have niche industrial uses where legacy hardware still relies on IR communication.

The ACPI NSC6001 is a testament to the layered complexity of modern computing. It is a deliberate software fossil, a translation layer that allows a twenty-first-century operating system to perform its most cherished trick: seamless power management and device enumeration on a platform that was never designed for it. acpi nsc6001

The ACPI\NSC6001 is a harmless artifact of a bygone era in computing. If you aren't actively connecting old Nokia phones or vintage PalmPilots to your computer, resolving the error by disabling the port in your Device Manager or BIOS will not affect your computer's performance or your daily computing tasks.

If the native update fails, legacy support packages hosted on repository sites contain the original installation files:

The ACPI NSC6001 is a device that has been identified as a part of the ACPI namespace, a hierarchical structure used to organize and manage ACPI components. The "NSC" prefix likely refers to the device's manufacturer or designer, while "6001" appears to be a model or product number.

Note: This won't enable the chip's special features (like IrDA), but it makes the exclamation mark go away.

Enter the NSC6001 . It sits as a logical device on the LPC bus, acting as a hardware translator. From one side, it speaks LPC to the modern chipset; from the other, it generates the correct -MEMR, -MEMW, -IOR, -IOW strobe signals and handles the complex, non-multiplexed address lines of a true ISA bus. The NSC6001 device in the ACPI namespace is the software declaration of this translation layer. | | Virtual machine passthrough | Hyper-V or

Alternatively, if you don't use infrared, you can often the device in Device Manager to stop Windows from alerting you about the missing driver. IrDA Fast Infrared Port Driver for Acer - Extensa 5620

If you have no intention of using infrared data beams, the most efficient fix is to disable the device entirely at the hardware level. This saves system resources and removes the error cleanly. Reboot your computer.
