The TBS Montego II Multifunction PCI Platform is a PCI card produced by TBS Technologies, which provides a combination of features, typically including high-definition audio and possibly TV tuner capabilities depending on the specific model. It is often referred to as a multifunction platform because it may include multiple functions beyond just audio, such as TV and satellite reception, depending on the variant.

The Windows driver for the TBS Montego II Multifunction PCI Platform allows the operating system to communicate properly with the hardware, enabling it to perform its functions (e.g., audio playback, TV reception, etc.).
