Pre-release Version 1.0. Formerly called "PC+MP Specification"
Version 1.1. Resolves conflicts with MCA-based systems. The following
changes have been made:
1. Two MP feature information bytes were moved from the BIOS System
Configuration Table to the RESERVED area of the MP Floating Pointer
2. If the MP Floating Pointer Structure is present, it indicates that the system
is MP-compliant, in accordance with this specification. (Previously, this was
indicated by bit 0 of MP Feature Information Byte 1.)
3. One more hardware default system configuration was added for MCA+PCI
with the integrated APIC.
Minor technical corrections.
Added Appendix D: Multiple I/O APIC Multiple PCI Bus Systems.
Version 1.4. Added extended configuration table to improve support for
multiple PCI bus configurations and improve future expandability. Made
clarifications to Appendix B.
Added Appendix E: Errata. Includes information for hierarchical PCI bus.
Appendix E Update. Included Byte 2, Bit 6 information to MP Floating Point
Structure section (4.1).
