#UEFITOOL RELEASE CODE#
Could someone point me in the right direction if this is not the case?Ĭlick to expand.I have got this problem when I tried It, the patch is based on code (or hex value) pattern and the program I figure if anyone can help with this it would be someone here. I posted this here because I've been using your tool to extract the modules from the uefi bios. ^_^ I think it's buried in the security core. If anyone could possibly help me find exactly where that value gets read, or possibly give me some pointers on how I might be able to locate that function, that would be great. If I remember right, it's the rightmost byte of the ebx register after executing the cpuid instruction with eax:0000000b, ecx:00000000, And once more with ecx:00000001. What I'm looking to do is trick the bios into reading the "number of logical threads per block of execution resources" byte incorrectly. The bios performs a check to see what resources the chip has to offer, and sets up nearly everything around that. My preliminary testing seems to indicate that the non functional portions of the instruction pipeline are in fact there, and only need to be recognized by the bios to function again. I'm not sure how it happened, but it did, and I want to see if it can be replicated. Over on ocn, there was a guy who had the ht feature magically enabled on his i5 chip. I signed up specifically so that I could ask a few questions.

Because of you make any mistake and flash the faulty file to your motherboard, it can turn the motherboard into a dead brick. UEFITool is only meant for the advanced users who have all the knowledge needed to modify the UEFI BIOS files. You can extract the part of memory as is, extract just the body, rebuild the firmware after modifying it, insert new modules, replace the modules and more. If you want to edit any of these, you can right-click on them and it will show you different options. After the firmware images are loaded, you can see all the various parts with their displayed with their names, type and subtype, description text and extra information.
UEFITool can load and analyze a number of UEFI firmware file types including ROM, BIN, CAP, BIO, FD, WPH and EFI. You can use it to load the firmware image file and it will show you all the various parts inside the firmware file. This tool is not for the beginners and is strictly for the advanced users who have good knowledge of the UEFI structure and how all the things work.
#UEFITOOL RELEASE WINDOWS 10#
In fact Windows 10 has in-built support to access UEFI and make changes to it.īut if you want to customize the UEFI firmware, then you can use the open-source UEFITool software. UEFI has the flexibility of being easily accessed from withing the operating system itself. But now all the new computers are coming with newer UEFI support which is a successor of the older BIOS. The older BIOS was pretty much permanent unless the manufacturer released some patched. In the older days, all the motherboards came with a BIOS chip that held a small set of instructions to initiate the hardware interface before the operating system took over.
