Processor Initialization

The following section describes the memory initialization performed by the Intel® SE7520AF2
Server BIOS.
5.3.1

Multiple Processor Initialization

IA32 processors have a microcode-based BSP-arbitration protocol. On reset, all of the
processors compete to become the bootstrap processor (BSP). If a serious error is detected
during a Built-in Self-Test (BIST), that processor will not participate in the initialization protocol.
The first processor that successfully passes BIST is automatically selected by the hardware as
the BSP and starts executing from the reset vector (F000:FFF0h). A processor that does not
perform the role of BSP is referred to as an application processor (AP).
