Description
When the Secure Boot feature is enabled, the system BIOS authenticates each UEFI
driver against the Secure Boot policy. If a UEFI driver does not meet the policy
criteria, the system BIOS does not load or execute the UEFI driver and displays this
message at the end of POST. The Secure Boot policy consists of authorized and
unauthorized X.509 certificates; signed drivers must chain to an authorized
certificate. The policy may also authorize hash values of individual UEFI driver
images. Users can configure the Secure Boot feature and the Secure Boot policy in
F2 System Setup > System BIOS > Security Settings page.
