INTRO
First of all I will explain that it does exactly this and for who serves and for whom it does not work:
This will basically allow to evade the HWID that puts EAC, it could even serve for other games besides Dead by Daylight.
What do these "Utilities" created by AMI (American Megatrends Inc) exclusively for BIOS AMI, usually ASUS motherboards carry this BIOS, but also some MSI among many other manufacturers have BIOS AMI, is to modify the BIOS Series Numbers and the Mother Card in addition to the name of the manufacturer, the UUID (which is the unique "name" identifier of each PC, this unique identifier is not easy to erase or change since as its name indicates, it is unique in the ROM of each Mother Card, as well as the Serial Number).
Prerequisites
You will need to have 1 free USB to install Free-DOS and also another means of installation of Windows (CD-DVD-USB), since at the end of this guide you will need to install Windows again then Steam and then Dead by Daylight.
Also you need the attached zip
A) As mentioned before, it is MANDATORY to have an AMI BIOS, if they do not count on it, these utilities will not work or they will do it halfway.
B) Preferably try it with ASUS motherboards, which is what I tried it with. But it is not essential, since as commented could work in any MOBO with a BIOS AMI.
C) Configure some elements in the BIOS as I describe them below:
1) Enter in the BIOS (keyboard function "F2" or "Delete" key when starting the PC, ASUS image)
2) Switch to Advanced User mode of the Bios and go to the "Boot" section and deactivate "Fast Boot" as seen in the image:
3) Open "CSM (Compatibility Support Module)" and in "Launch CSM" put AUTO as in the image:
4) Return to "Boot" and open "Secure Boot", here we are going to deactivate it, also in "OS Type" choose Other OS as seen in the image it has to be, if not, continue to step 5:
5) If the "Secure Boot" is activated, you must deactivate it by deleting the keys in the following way:
And it should look something like this:

D) We will need a free memory (all will be erased) USB-flash stick (no matter the size) we will also need the Rufus program that contains this ZIP) to be able to install a DOS environment on the USB and boot on the PC from this USB
1) Insert the USB and open Rufus. In "Device" we select our USB, in "Boot Selection" we select FreeDOS, this will change the correct format:
2) Now we give in "Start" until below the program, this will format the USB and it will erase all the content, when the green bar ends it will be full and it will say "Ready", we give in "Close" to finalize the program and test our USB with MS-DOS:
3) Restart the PC with the OpenDOS USB, when loading the ASUS image, press the F8 key to enter the Boot menu, there we select our USB, there may be two types, from our USB in the boot menu, ignore the one that say UEFI, we will start with the other. If everything works correctly, the black screen should appear with the prompt or MS-DOS symbol and the letter C:/ (to exit from here with turning off the PC, removing the USB and starting the PC again in Windows).
E) Once created our USB with bootable MS-DOS, we will copy the contents of this ZIP in the USB root for greater ease and access when we are in Free-DOS looking something like this:
Change the Serials and the UUID of the MOBO:
(
Clarification: since I can not do screenshots in Free-DOS I will use the tool from a Windows console, so I will use the "AMIDEWIN" tool, but you must use the AMIDEDOS.EXE tool when using your USB FREE-DOS, the commands they are the same, but you will use AMIDEDOS instead of AMIDEWIN)
1) We start from our USB in FREE-DOS, we will be in the root C: / and we will put the following command:
This will show them the number or a phrase of the current serial, in my case it is "Serial Number" like this:
To change it we need to use the same command and add a new serial number invented by us. Let's say that the number we want is 0123456789 then the command would be like this:
Code:
AMIDEDOS.EXE /SS 0123456789
It should look like this:
To verify that it has been changed we will use the previous command:
2) Now let's change the UUID, this is done automatically, first we verify the current one with the following command:
Then we repeat the same command but we will add the word AUTO with the following command:
Code:
AMIDEDOS.EXE /SU AUTO
It must look something like this:
We verify that it has been changed with:
3) Finally we will change the serial of the Motherboard, this will be done with the following command to verify the current serial:
Then we will change the serial by which we want in my case it will be 9876543210 with:
Code:
AMIDEDOS.EXE /BS 9876543210
To verify what was changed we use:
It should look something like this:
4) We restart the PC by simply switching off. We will have to reboot the USB MS-DOS to verify that everything that has been changed has been changed, this command can be used at once:
Code:
AMIDEDOS.EXE /SS /SU /BS
If the three serials have changed this will be everything, it should look like this:

Now that we have new Serials we proceed to Install Windows / Steam / Dead by Daylight in a new account and avoid the Ban.
See you in the fog.
