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.… >>>Click Here To Continue Reading

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. Dealing with all these negative aspects was trivial but annoying, which is why Module Helper was developed. It was originally  capable of splitting the modules header and data into separate files an it could update the sizes in the headers.… >>>Click Here To Continue Reading

BIOS Spotlight: (UEFI) Dell XPS 15z L511z

This article documents the exciting work being done by some of the top contributors in our forum. The modifications performed on systems like the Dell 15z reflect the most advanced examples of BIOS modifications done within our  community.  For more information, please visit the thread.
Phoenix SecureCore Tiano, used by Dell, is a tough nut to crack – we came to what we have today by taking little steps on a road that wasn’t smooth to begin with. Phoenix nor Dell have provided any information regarding SCT 2.0 and to this day the BIOS on these machines has not been upgraded to 2.3.1 which allows for ME v8 (brings IVB CPU support) and SecureBoot capabilities.… >>>Click Here To Continue Reading

UEFI, Secure Boot and what it means to you

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.

Windows is still the most popular PC Operating System in the world. As such, it is highly likely that the computer you are reading this article on is running some version of Microsoft Windows. If you are running Windows 7 and up, your OS is compliant to UEFI specifications. But what if you want to run a different OS, like Linux, older versions of Windows?… >>>Click Here To Continue Reading

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. Years went by and the CPU became more powerful, with a wider bus and more memory access. However, the BIOS remained the same, and retained it’s 16bit bus and 1MB memory limit, depending on the PC-AT hardware platform.

Enter EFI/UEFI (Extensible Firmware Interface/Unified Extensible Firmware Interface respectively).… >>>Click Here To Continue Reading

Intel UEFI Motherboard 2.1 SLIC Modding May Be Possible!

Hey Everyone

Ive got some really good news for owners of Intel motherboards which use the UEFI framework (Newer BIOS). Up until now Intel boards couldnt be modded for SLIC 2.1 but after some hours of scouring the internet I found a post which i translated and am ready to provide to those willing to test.

In theory , this method should work for ALL Intel Motherboards using UEFI. The original poster has fully confirmed this mod working on an Intel DG45ID motherboard , so you should at least give it a go if you have one of these!

Basically , the mod allows you to access the UEFI Terminal Interface and therefore lets you “Inject” a Dell 2.1 SLIC into the bios.… >>>Click Here To Continue Reading
