The ATI Rage Theater 213RT1ZUA43 is a legacy video-processing chip used on certain ATI graphics and multimedia boards. Its driver helps Windows communicate with the chip’s video-input and TV-output functions, where supported by the host card, installed software, and driver package.

Key Features

• Video-input support: Enables compatible capture software to access the board’s analog video inputs, such as composite or S-Video, when those connections are available.
• TV-output integration: Supports the board’s video-output capabilities when paired with the appropriate ATI graphics driver and compatible hardware.
• Multimedia device recognition: Helps Windows identify and configure the Rage Theater component rather than leaving it listed as an unknown multimedia device.
• Board-specific functionality: Provides the software interface needed for supported video-processing features. Available options depend on the complete card model, not just the 213RT1ZUA43 chip marking.

How to Install

1. Identify the complete graphics or capture card. Open Device Manager and check the device’s properties. Under Details, select Hardware Ids to help match the hardware to the correct package. The ATI Rage Theater 213RT1ZUA43 marking alone may not identify the required driver.

1. Check Windows compatibility before downloading. For Windows 11, 10, 8, or 7, verify that the package explicitly supports your operating system and architecture. This legacy hardware may lack compatible drivers for newer Windows versions; an older ATI package is not automatically suitable.

1. Prepare the system. Create a restore point if System Protection is enabled. If the card manufacturer specifies a required graphics driver or installation order, follow those instructions before installing the multimedia component.

1. Install the matching driver. Extract the download if necessary, then run its installer as an administrator. If the package requires manual installation, use Device Manager, select Update driver, and browse to the extracted driver folder. Do not force installation of a package that does not match your hardware.

1. Restart and test the available functions. Check Device Manager for warning icons, then test video input or TV output using compatible software and connected equipment.

If installation fails or Windows reports an unsupported driver, recheck the card model and package requirements. Compatibility mode cannot make an incompatible hardware driver work, and disabling driver-signature protections is not a reliable solution.

Common Issues and Fixes

• Install fails or rolls back: The Rage Theater 213RT1ZUA43 uses legacy ATI WDM capture drivers that may be unsigned or blocked on newer Windows. Run the installer as administrator in Windows 7 compatibility mode; if it still fails, install the capture/WDM INF manually via Device Manager and disable driver signature enforcement only for the install.
• Device not detected: Confirm the card is seated and its PCI/AGP slot is enabled. In Device Manager, look for an unknown “Multimedia Video Controller” or “ATI Rage Theater.” Reseat the card, try another slot, and install the matching ATI WDM capture driver rather than a generic display driver.
• Version conflicts: Remove older ATI WDM/MMC packages and reboot before installing the matching driver set. Avoid Windows Update’s generic video driver; mismatched WDM capture/tuner versions can cause Code 10/43 errors.
