Universal IFR Extractor

In case you didn’t already know, the Extensible Firmware Infrastructure’s Human Interface Infrastructure uses Internal Forms Representation protocol to display things like your setup utility’s menu. By having access to the Internal Forms Representation, we can know everything about a menu which can assist us immensely when modding bios. I’ll also be using this application in a few of the tutorials I write, so get used to using it now   I was getting tired of all the requests to expand EFI IFR Dumper to include support for UEFI’S IFR protocol, and as a result I decided that now is a better time than any to update my program.… Read the rest

Module Helper

I first started working on Module Helper back in September when Andy’s tool V2.19 was released. As some of you may know, that iteration altered the format of the extracted EFI modules by storing a module’s header, code, and name all in the same file. This created some issues with disassemblers not being able to automatically recognizing the format of the EFI modules and the size of data modules not being updated if changed.… Read the rest

With the advent of UEFI and Windows 8 comes some security and usability issues. When Windows 8 is released, UEFI’s “Secure Boot” will be required to be turned on by default and it will be left to the OEM’s on how to implement it. What does this mean to you? Maybe nothing.… Read the rest

Out with BIOS, in with UEFI.

Ever since the computer was born, there needed to be a program to tell the CPU where things are and how to use them. In 1981 the IBM 5150 introduced the BIOS (Basic Input/Output System) to the IBM-PC market. The IBM 5150 had an 8088 16bit (16bit internal bus, 8bit external bus) processor, so the BIOS chip was limited to 16 bits and 1MB of memory space.… Read the rest
