Before putting a replacement or new System Board into a production environment, you should run high level hardware HPOST tests against that board and components to confirm its sanity.

To reduce domain downtime while doing these hardware tests, a method for testing this new or replacement hardware is to configure the board in its own "test" domain for extended HPOST testing.

The method below can be used to test a single Slot0 board (System Board) in a "test" domain without a Slot1 (IO or maxcpu) board in the configuration. After successful testing has completed, the new or replacement board can be dynamically reconfigured (DR'ed) into the production domain with confidence that it does not contain bad hardware.
