This post describes the changes and enhancements which I recently made to my ShowBGRT utility which is a simple tool to extract information and the boot logo image using the ACPI Boot Graphics Resource Table. This post details the changes I made to my DisplayBPM UEFI shell utility to support more formats, better image header checks, and vertical scrolling of screen whenever necessary to fully display the image. This post discusses the CPUID opcode which is available for IA32 and IA64/AMD64 platforms. The source code for a simple cpuid utility is also provided. In this post, I discuss activation of Microsoft Windows using the SLIC mechanism, and provide source code for a UEFI shell utility that exposes all available SLIC information. |
