Pre-boot authentication can by performed by an add-on of the operating system like Linux Initial ramdisk or Microsoft's boot software of the system partition (or boot partition) or by a variety of full disk encryption (FDE) vendors that can be installed separately to the operating system. Legacy FDE systems tended to rely upon PBA as their ...
Windows 8 and later have native support for TPM 2.0. Windows 7 can install an official patch to add TPM 2.0 support. [92] Windows Vista through Windows 10 have native support for TPM 1.2. The Trusted Platform Module 2.0 (TPM 2.0) has been supported by the Linux kernel since version 3.20 (2012) [93] [94] [95]
Valorant will not run on Windows 11 if the system does not have a Trusted Platform Module (TPM) 2.0 compliant cryptoprocessor and UEFI secure boot enabled, as mandated by Microsoft's minimum system requirements for the operating system. [73]
In Windows, if Secure Boot is enabled, all kernel drivers must be digitally signed; non-WHQL drivers may be refused to load. In February 2013, another Red Hat developer attempted to submit a patch to the Linux kernel that would allow it to parse Microsoft's authenticode signing using a master X.509 key embedded in PE files signed by Microsoft.

In contrast to the normal processor initialization [which involved the boot-strap-processor (BSP) sending a Start-up Inter-Processor Interrupt (SIPI) to each Application Processor, thus starting each processor in "real mode" and then transitioning to "virtual mode" and finally to "protected mode"], the operating system avoids that vulnerability ...
