Zusammenfassung:	An information handling system includes multiple components including a first component. The first component includes a protected memory and a basic input/output system (BIOS). The protected memory stores a revoked versions list. The BIOS initializes a firmware update for a firmware image having a firmware version. The BIOS scans the revoked versions list for the firmware version of the firmware image. In response to the firmware version not being located within the revoked versions list, the BIOS completes the firmware update, and determines whether a revoked firmware version is included in the firmware update. In response to the revoked firmware version being included in the firmware update, the BIOS adds an entry in the revoked versions list. The entry is associated with the revoked firmware version included in the firmware update.
