In this post, I provide the source code for a working UEFI shell application which displays the contents of an ASCII file using functionality provided by EFI_SHELL_PROTOCOL.

In this post, I discuss a number of key TPM 2.0 features such as multiple algorithm support and PCR banks, and provide the source code for a UEFI shell utility to display the digests from the first 24 PCRs of a TPM 2.0 implementation. This post discusses the UEFI 2.4 Random Number Generator protocol and Lenovo’s current implementation of the protocol and suggests there is an error in their implementation. This post describes the role of the BCD store in booting Windows 10 on a UEFI-based platform. It describes a number of other files used in the boot process and a workaround for booting your system from the UEFI shell should you encounter the 0xc0000034 error code. This post details the two UEFI OS Indication variables and provides the source code for a small UEFI shell utility, buildable with UDK2015, which retrieves the current value of the two variables |
