1. A programmable power management circuit for controlling a power supply within a computer system comprising:

  • a switch for applying power from the power supply to a processor within the computer system;

    a first memory which stores default configuration data for controlling the power supply;

    a power control circuit which senses power from the power supply and which controls the switch; and

    a loader circuit which sends a signal to the power control circuit and which replaces the default configuration data in the first memory with configuration data specific to the computer system from a second memory;

    wherein the power control circuit produces a control signal, after receiving the signal from the loader circuit, that causes the switch to apply power to the processor so that the computer system can boot up; and

    wherein the configuration data specific to the computer system is read by a power supply controller to control the power supply.
