Sharing firmware among a plurality of agents including a plurality of central processing units (CPUs) on a node is described. In an example, a computing node includes: a bus; a non-volatile memory, coupled to the bus, to store firmware for the plurality of agents; a power sequencer to implement a power-up sequence for the plurality of CPUs; a plurality of power control state machines respectively controlling states of the plurality of CPUs based on output of the power sequencer; and a bus controller to selectively couple the plurality of agents to the non-volatile memory based on state of the plurality of power control state machines.
