A method and system for sharing platform data are described. The method for sharing platform data includes during a boot sequence of system firmware, accessing a first data structure tag associated with a resource accessible by the operating system. Also during the boot sequence of the system firmware, the method includes determining a memory address corresponding to platform specific data associated with the resource. During a boot time sequence of the system firmware, run time code is parsed. The method includes accessing a second tag that is visible to the operating system and associating it with the location of the platform specific data. This allows for the platform specific data to be consumed by an operating system during runtime in accordance with the industry common interfaces defined in ACPI.
