Abstract: A processor can be configured to access boot firmware from a remote location independent from use of a chipset. After a processor powers-on or reboots, the processor can execute microcode. The microcode will cause the processor to train a link with a remote device. The remote device can provide the processor with access to boot firmware. The processor can copy the boot firmware to the processor's cache or memory. The processor will attempt to authenticate the boot firmware. If the boot firmware is authenticated, the processor executes the copy of the boot firmware.
