RHEL/CentOS 7 uses SystemD predictable network interface names. This post shows you how to rename a network interfcae to eth0,/em>without modifying the kernel commnad line or any udev rules, and without requiring a sytem reboot. In this post, I show you how to install and configure UDK2017 on Fedora 26. I also show you how to build a simple HelloWorld UEFI application using the installed UDK2017 tools and environment. 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 how to convert and parse Intel microcode files for Linux systems and provides two Python 3 scripts to assist you in this task. |
