| |
Hello All,
Recent interaction with BIOS teams within in my Organization left me wondering if MP table spec from Intel is no more a mandatory one http://www.intel.com/design/pentium/datashts/24201606.pdf
Section #8.4.5 http://www.intel.com/Assets/PDF/manual/253668.pdf Talks as ACPI or MPS table. That means BIOS can report through ACPI tables only.
I looked through x86 boot sequence and notice Linux scanning for MPS table in below locations and Linux doesn't seem to go further without MPS table or doesn't know how to live with ACPI only. 1) Scan the bottom 1K for a signature 2) Scan the top 1K of base RAM 3) Scan the 64K of bios
Your insights into this topic are appreciated.
Thanks, Sreenivas
