ABSTRACT:
A multi-task boot strap system and method for expediting boot up initialization processes are presented. In one embodiment, a multi-task boot strap method includes accessing interrupt vector table information stored in a non-volatile memory. For example, an interrupt vector table and corresponding interrupt service routine information associated with a system management (SM) bus controller operation are accessed from a read only memory (ROM). A program interrupt controller (PIC) is initialized to interpret the interrupt information from the non-volatile memory. This permits the operation of the system management bus controller to be performed in a multi-tasking environment (e.g., operating the SM bus controller in an interrupt mode). A processor can be configured to retrieve the boot up information (e.g., serial presence detect data) and process interrupts with interrupt service routine information retrieved from non-volatile memory. The processor can performing other multi-task operations while waiting for an interrupt during boot up operations.
