First Claim
Patent Images
1. A method for multi-processor initialization in an information handling system, comprising:
- providing two or more application processors (APs) within an information handling system;
configuring one of the APs to be a boot strap processor (BSP) for the information handling system;
operating the BSP to communicate with the other APs to initialize the APs prior to initialization of main memory; and
operating each AP to communicate with the BSP for AP initialization.

Abstract
Methods and systems are disclosed for multi-processor initialization in an information handling system with two or more application processors (APs). One of the APs is configured to be a boot strap processor (BSP) that communicates with the other APs to initialize them prior to initialization of main memory. A basic input output system (BIOS) can be coupled to the APs and can be configured to hold BSP code and AP code used for initialization. APs are then discovered and initialized before the main memory of the system is initialized.

14. An information handling system having multi-processor initialization for multiple application processors, comprising:
-
two or more application processors (APs) within an information handling system, at least one application processor (AP) configured to be a boot strap processor (BSP) for the information handling system; a basic input output system (BIOS) coupled to the APs; main memory coupled to the APs; BSP code within the BIOS, the BSP code configured to cause the BSP to communicate with the other APs in order to initialize the APs prior to initialization of main memory; and AP code within the BIOS, the AP code configured to cause each AP to communicate with the BSP for AP initialization. - View Dependent Claims (15, 16, 17, 18, 19, 20)
