A 1.375 MB binary firmware file identified only by version 2.1.4.3102 and the PRD and EXTR markers. The scheme resembles Intel Management Engine firmware naming, with PRD meaning a production release and EXTR an image extracted from a full package or dump. The name gives no motherboard or laptop model, so compatibility has to be judged by the platform's ME firmware generation. Technicians typically use such images to rebuild a damaged ME region; always dump and archive the existing chip contents first and verify region size.
