Dell PERC13 and PERC12 User’s Guide PERC H975 Series and PERC H965 Series cards

UEFI Secure Boot is a technology that eliminates a major security void that may occur during a handoff between the UEFI firmware and UEFI operating system (operating system). In UEFI Secure Boot, each component in the chain is validated and authorized against a specific certificate before it is allowed to load or run. Secure Boot removes the threat and provides software identity checking at every step of the boot-Platform firmware, Option Cards, and operating system BootLoader. For more information about using UEFI Secure Boot in PowerEdge servers, see the "Secure Boot Configuration from BIOS Settings or F2" section of the iDRAC User's Guide available on the support site.

To view a list of supported operating systems, see PowerEdge server supported operating systems. By default, Windows and VMware support UEFI Secure Boot on both in-box and out-of-box drivers. However, Linux supports Secure Boot only with in-box drivers. For Out-of-Box Linux drivers, you must install the Broadcom public key in the UEFI or operating system signature database. For information about installing a signature database, see the technical documentation of the respective platform or operating system. The Broadcom Public database key is provided with an OS driver package on the Dell support site. The following table lists the operating system and their supported driver types and also indicates whether the UEFI Secure Boot feature is supported with PERC.
