The is part of the (Input/Output) technology, which is a set of interfaces that allows communication between a processor (like an Intel CPU) and peripherals connected through I2C (Inter-Integrated Circuit) or SPI (Serial Peripheral Interface) buses.

In essence, this driver allows Windows to properly interface with devices on the I2C bus, such as sensors, touchpads, or other low-speed peripherals, that are managed by the Intel Serial I/O controller.

The typically requires a driver for the operating system to correctly communicate with devices using the I2C protocol. The specific version 98E9 is associated with a particular revision of the controller or a specific chipset family.
