Corrected Figure 5-1 location of system description tables. Removed redundant
description of finding the RSDP on IA-PC systems – added reference to other
sections.
Corrected FADT Boot Architecture Flags Reserved field bit offset from 3 to 2.
Clarified _INI object evaluation – OSPM evaluates \_SB._INI
Corrected ElseTerm definition. Changed CMOS RegionSpaceKeyword to
SystemCMOS to avoid collisions with existing ASL.
Corrected description of Mutex object.
Changed ASL CopyTerm to CopyObjectTerm to avoid collision with existing

Corrected location of Firmware ACPI Control Structure may exist anywhere in
the system’s memory address map.
Corrected description of the Local APIC Address Override Structure.
Corrected Local SAPIC Structure’s ACPI Processor ID field length from two
bytes to one byte to enable a correct comparison with processor term’s
ProcessorID field. Rearranged field ordering to more closely match the Local
APIC Structure.
Corrected _SCP reference section.
Corrected TermArg and NameTerm to reference DataObject rather than
DataRefObject. Added NameString to TermArg. Added missing DDBHandle
and ObjectReference to ASL type definitions.

Clarified that OSPM is only required to write non-zero values of FADT fields
PSTATE_CNT and CST_CNT to the SMI Command Port. Corrected
PM1_CNT_LEN value is ≥ 2.

Clarified hardware interfaces may be defined as Functional Fixed Hardware
only when directed by the CPU manufacturer as proprietary OS support is
required that must be coordinated with the OS vendor.
Clarified Definition Block support expanding from 32-bit to 64-bit integers.
Local SAPIC Structure length corrected to 8 from 10 bytes.
