ABSTRACT:
A method and system for dynamic creation of APIC tables under the ACPI specification using existing APIC tables under the MP specification in a multi-processor computer. The method of the present invention provides for the dynamic creation of APIC entries in a computer memory, and includes the steps of: scanning the memory for an MP APIC header, reading MP APIC entries from a location in the memory indicated by the MP APIC header, building ACPI APIC entries in the memory from at least a portion of the MP APIC entries read, and updating an ACPI APIC header in the memory after the ACPI APIC entries have been built.
