The NEC FireWarden 1394 OHCI Compliant Host Controller driver allows Windows to communicate with the controller that manages your computer’s IEEE 1394, or FireWire, ports. It supports connections to compatible equipment such as digital camcorders, external storage devices, and audio interfaces. This Microsoft-provided driver is intended for supported configurations running Windows 10, 8.1, 7, Vista, or XP; choose a package that matches your Windows version and system architecture.

Key Features

• FireWire controller recognition: Helps Windows identify the NEC FireWarden 1394 OHCI Compliant Host Controller and make its ports available to connected hardware.
• OHCI-standard operation: Provides the software interface used by Windows to work with an Open Host Controller Interface–compliant IEEE 1394 controller.
• Data transfer support: Enables communication between the computer and compatible FireWire peripherals, subject to the capabilities of the controller, cable, and connected device.
• Windows integration: Works with the operating system’s driver framework so you can check controller status and manage the installed driver through Device Manager. Some peripherals may also require their own software or drivers.

How to Install

1. Check your Windows configuration. Confirm whether you are using Windows 10, 8.1, 7, Vista, or XP, and identify whether the installation is 32-bit or 64-bit. Verify that the download explicitly supports that configuration and your controller.

1. Download and prepare the driver. Save the compatible package to a convenient folder. If it is compressed, extract its contents before starting installation. Create a restore point if System Protection is available and enabled.

1. Locate the controller in Device Manager. Look under “IEEE 1394 Bus host controllers.” If the driver is missing, the hardware may appear under “Other devices” or display a warning icon. Check its hardware IDs if identification is uncertain.

1. Install the matching driver. Run the included installer, if provided. Otherwise, right-click the controller, select the driver-update option, and browse to the extracted folder. Menu wording varies between Windows versions. Do not force installation if Windows reports that the package is incompatible.

1. Restart and test the connection. Restart if prompted, then confirm that Device Manager shows no controller errors. Connect a known-working FireWire peripheral and check that it is detected. If problems continue, inspect the cable and verify any additional driver requirements for the peripheral.
