There are two BIOS attributes that are associated with Secure Boot: • Secure Boot - Displays if the Secure Boot is enabled or disabled. • Secure Boot Policy - Allows you to specify the policy or digital signature that BIOS uses to authenticate. The policy can be classified as: - Standard - BIOS uses the default set of certificates to validate the drivers and operating system loaders during the boot process. - Custom - BIOS uses the specific set of certificates that you can import or delete from the standard certificates to validate the drivers and operating system loaders during the boot process. NOTE: The Secure Boot Policy is read-only in Lifecycle Controller. You can change this setting only in the BIOS. To enter BIOS system setup, press during POST. NOTE: The Secure Boot feature is supported on the Dell 12th generation PowerEdge servers, only if BIOS on the system supports this feature. To deploy an operating system using the Secure boot option, see Installing An Operating System. NOTE: For more information on UEFI, go to uefi.org. Related links Installing an operating system Using the optional RAID configuration Driver access Lifecycle Controller provides a local repository for drivers that are required for installing the operating system. Based on the operating system you want to install, the OS Deployment wizard extracts these drivers and copies them to a temporary directory (OEMDRV) on the managed system. These files are deleted after 18 hours or when you: • Refresh the AC power cycle, which resets the iDRAC. • Press select iDRAC Settings or Lifecycle Controller to cancel the Lifecycle Controller actions. NOTE: Before installing an operating system, make sure that Lifecycle Controller is updated with the latest driver packs. You can download the latest Lifecycle Controller drivers at dell.com/support.
