Users Guide

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 import or delete from the standard certificates to validate
the drivers and operating system loaders during the boot process.
NOTE: The secure boot policy settings made on BIOS can also be changed on the Lifecycle Controller GUI.
NOTE: For more information on UEFI, go to uefi.org.
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 <F2> 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 https://www.dell.com/support.

The system prompts you to press a key to boot from the operating
system installation media.
Cancel operating system installation. Press <F10>.

to a temporary location after the operating system is
installed, you cannot update the component firmware
Lifecycle Controller does not allow DUP after the operating system
installation. However, if you disconnect the power supply to the
managed system, the OEMDRV directory is erased.
