Configuration and Boot Management ➙ Intel Optane DCPMMs ➙ Goals will go back to the
following default selectable options:
• Scope: [Platform]
• Memory Mode [%]: 0
• Persistent Memory Type: [App Direct]
These values are selectable options for DCPMM settings, and do not represent the current DCPMM
status.
