Adding support for a new Super I/O chip is usually not significantly hard once you have obtained the datasheet for your target chip. Herein we shall outline the steps usally taken for a bringup. | Adding support for a new Super I/O chip is usually not significantly hard once you have obtained the datasheet for your target chip.

== Super I/O introduction == | |||
Every Super I/O chip provides different kinds of functions to the computer, such as control over GPIOs, GAME port, MIDI port, fan controllers, infrared and more. | |||
Each of these functions, inside a Super I/O, is split into its own logical device and everyone of these devices is identified by an hex number (starting from 0x0) called logical device number (LDN). | |||
I.e. 0x05 and 0x06 are the LDN respectively for the keyboard and the mouse. | |||
Check your chip's datasheet to find the complete list. | |||
