A system and method for multiple processors operating independently from one another to share memory as a boot device. The system includes a plurality of computing systems each including a processor and a local memory element. In response to a boot condition for a selected computing system, its processor begins a boot sequence in which it uses operational code contained within a non-volatile memory element that is shared by each of the computing systems. Arbitration for ownership of a memory bus interconnecting the non-volatile memory element to the processors and organization of a direct memory access transfer between the non-volatile memory element and local memory associated with the processor of the selected computing system is controlled by a memory access coordination circuit coupled between the computing systems and the memory bus. |
