An information handling system, comprising:

• a controller coupled to a central processing unit;
• and
• a management controller coupled to the central processing unit and the controller;
• wherein the central processing unit is operable to:
• initiate a connection to the management controller through the controller;
• send a message to the management controller through the controller;
• receive a message from the management controller through the controller in response to a system management interrupt;
• stall a power-on procedure if the first code is able to determine a plurality of bootable devices before the connection to the management controller is ready;
• and
• stall the power-on procedure before releasing control to an operating system if the management controller is active.

A method of operating a BIOS, comprising:

• executing a first code on a central processing unit, the step comprising:
• initiating a connection to a management controller through a controller;
• sending a message to the management controller through the controller;
• receiving a message from the management controller through the controller in response to a system management interrupt;
• stalling a power-on procedure if the first code is able to determine a plurality of bootable devices before the connection to the management controller is ready;
