| UFU_020 | Systems with in-band firmware updates MUST do so either via UpdateCapsule() UEFI runtime service (cite:[UEFI] Section 8.5.3) or Delivery of Capsules via file on Mass Storage Device (cite:[UEFI] Section 8.5.5).
| UFU_030 | Systems implementing in-band firmware updates via UpdateCapsule MUST accept updates in the "Firmware Management Protocol Data Capsule Structure" format as described in "Delivering Capsules Containing Updates to Firmware Management Protocol" cite:[UEFI] (Section 23.3).
| UFU_040 | Systems implementing in-band firmware updates via UpdateCapsule MUST provide an ESRT cite:[UEFI] (Section 23.4) describing every firmware image that is updated in-band.
| UFU_050 | Systems implementing in-band firmware updates via UpdateCapsule MAY return EFI_UNSUPPORTED, when called after the UEFI boot services have been exited.
| UFU_010 | Systems with in-band firmware updates MUST do so either via UpdateCapsule() UEFI runtime service (cite:[UEFI] Section 8.5.3) or Delivery of Capsules via file on Mass Storage Device (cite:[UEFI] Section 8.5.5).
