ABSTRACT:
The firmware interface table (FIT) of IA-64 instruction set is used to populate the hardware component namespace using SSDT data, where the SSDT data describes components in the system. At boot-up time all hardware components are discovered. The ACPI sub-system, in the system firmware, consumes the data set-up and loads the SSDTs from the FIT to create the namespace for the active system components. There is one FIT type indicating an SSDT entry, and the sub-type is indicated using the FIT version field.
