ABSTRACT:
A method includes powering up a system with a system control circuitry (SCC) that contains a central processing unit (CPU). The method includes holding the CPU in a reset condition. The method also includes retrieving, over a serial data bus using a serial communications protocol, information about a system memory configuration and a boot program from a first section of a programmable read only memory (PROM). The method also includes retrieving, over a serial data bus using a serial communications protocol, a first portion of the boot program from a second section of the PROM using the information about the system memory configuration and the boot program, writing the first portion of the boot program into a system memory, releasing the CPU from the reset condition, and booting the system using the boot program.
