Remote management of a computer system

An article of manufacture comprising:

• a machine-accessible medium including a plurality of instructions which when executed perform operations comprising:
• receiving a managed system change request at an out-of-band management controller of a computer system;
• posting the managed system change request to a mailbox;
• signaling the managed system change request has been posted to the mailbox;
• retrieving the managed system change request during a system management operating environment, wherein the system management operating environment is transparent to an operating system of the computer system;
• and
• modifying the computer system while in the system management operating environment based on the managed system change request.

A system, comprising:

• a processor;
• an Synchronized Dynamic Random Access Memory (SDRAM) unit coupled to the processor;
• a chipset coupled to the processor, the chipset including an out-of-band management controller;
• and
• at least one storage unit coupled to the chipset, the at least one storage unit having stored a plurality of instructions which when executed perform operations comprising:
• receiving a managed system change request at the out-of-band management controller;
• posting the managed system change request to a mailbox by the out-of-band management controller;
• initiating a System Management Interrupt (SMI) by the out-of-band management controller to signal that the managed system change request has been posted to the mailbox;
• entering a System Management Mode (SMM) of the processor, wherein the SMM is executed in a System Management Random Access Memory (SMRAM) address space of the SDRAM unit;
• retrieving the managed system change request from the mailbox during the SMM by the processor;
• and
• modifying the computer system during the SMM by the processor based on the managed system change request.
