31 | * A software-defined chip environment describing a virtualized x86 processor. |

33 | * chip identity may not be available. Therefore this environment is returned |
34 | * from {@link img4_chip_select_personalized_ap} and |
35 | * {@link img4_chip_select_effective_ap} when it is called on a virtual machine |
36 | * so that the appropriate chip environment is present entirely in software. |
