Hello, l'd like to know how to flash a bios mod in my asus x541uj laptop. I tried to extract a .rom with afudos, modified it with amibcp and flashed it with afudos (afudos biosmod.rom /gan). The process was "successfull" but no changes were done... I just want to show hidden options in order to disable enhanced intel speedstep for mao performance. Bios/uefi is an aptioV. Please, someone can help me

I also tried with ez flasher 3 with a modified bios renamed exactly like the one i get in asus page. "File isn't proper" or something like that... Is it possible to extract the body with uefi tool and the capsule separatly, modify tje body and then, fuse modified body with guenine capsule? Which utility could do that?

Thanks for your help fernando. I already this method but unfortunately changes were not applied. No problem during flash but there are 2 advanced folders

Now, when i want to save my modified bios, amibcp save it as an aptio files (.fd) and not a .rom file... It's weird

Fernando : I want to cry ... I hope I don't offend again by posting in the wrong section but, I feel like this is my last attempt to get the board I have working properly. I would be willing to pay quite the bounty at this point as I have invested 100's (LITERALLY) of hours attempting to get this board off the ground. I have been all over every possible utility only to arrive back where I started scratching my head in bewilderment.

FIRST OFF I would like to thank yourself, this community and all research done on this matter. In the past my matters have been abandoned short of any real solution and I feel it is my fault for complicating the matter. As these "specialty items" after production can often be abandoned for strategic purposes or otherwise all for good reason but I am thirsty to have the successes I have read this board over. In addition I think I am finally graduating to a level of knowledge that the adept could not be frustrated in my humble tackling of such a large project.

With that said my problem is that, I have been using 2 650 USD motherboards (Asrock Extreme11 X99). A ridiculous monster that I have regretted since purchase but have made so many customization's to the actual (physical) build I am left with the product at hand.

I realize I am dealing with an Aptio V and have therefore attempted modification with ; AFUwingui extraction as (AFUdos is no available in the package any longer from American Megatrends download. I did source it from this site and otherwise and when attempted to run from DOS boot received a immediate !power cycle directly at the command prompt) so that was off the table for extraction.

Although backup of the BIOS was successful with AFUwingui x86 and no parameters could be set *(x86 win 10), and editing with AMIBCP64 was both possible and seemed simple. Making one change for INTELRC menu access *(or so it would seem), provided the ability to be reflashed successfully with the same AFUwingui x86 with all parameters flag enabled. *(All ME was grey though ?) I was able to reboot POST and go into the UEFI/BIOS menu 1 time. and the the system would shut off during power cycle even after full clear CMOS.

BUT I won't quit as this could allow me to actually use my fans properly, move my PCIe cards more appropriatly, fix horrible USB glitches and otherwise. So I am not finished and if you look back my posts have always been in a similar light. I can't get this board to give up ANYTHING with APTIO V.

I want to cry (as a grown man due to loss of time and money and lack of success. SO HONESTLY let me pose a bounty PM me :)

FINALLY I have discovered Intel ME System Tools, but I can't get the system to POST with NO changes just being opened and saved and written to CMOS. :(

Now what any ideas; MMTOOL / or Coderushes UEFITOOL, pretty much no tool is available to anyone today that will allow me to access, and make alterations to my board. Almost everything results in debug code and no ability to clear the CMOS to resolve the problem.

I don't think it is the elements that I am changing either but each time I invest 45 minutes flashing rom, backups etc.

IS ANYONE out there able to help me make ANY changes AT ALL ?

Yes indeed ! You ARE right on that one AFUDOS is in fact still available. Though for the life of me I could not find that utility. I have yet to try it and I will report back if I can actually get it to function without immediate !power cycle at the prompt like the one from before that I downloaded and ran in a freedos USB flash drive boot.

For the last 12 months I have been using CodeRush's UEFITool in my attempts to flash a modded bios. In my case the download is a .20 file with no extension the utility provided me with the ability extract it on earlier versions. Lately I open with UEFI tool I don't receive an indication in is encapsulated any longer. So I proceed to UBU and it provides to lines during the opening script about removing the protection. If I save and rename the finished product I can remove the cpu microcode entirely for instance. REFLASH from within BIOS and it works PROPERLY. Even POSTS.

Because I can't understand fully what is going on behind the seems and I can't seem to resource the information even if it be a full manual that will point me in the right direction as to how I can truly modify myself certain key things.

UEFITool is obviously where I am failing then, as I cannot understand the format with my limited knowledge and don't know how to resource the proper learning materials to utilize the full functionality of UEFITool, I have yet to do anything outside of removing a bios from capsule. And for the life of me can't seem to click my way through the tree until I arrive at the functions I am seeking. :( In AMIBCP64 or Intel ME System Tools. I was overjoyed to see a clean useful menu that I was at least able to tailor nicely and even opting for no changes saving flashing resulted in a successful flash with and debug of 94 (PCIE fail). Every time. One time wayyy back I clipped and pruned my own patches in. It worked, but it was a mess, other things were very off and I think my MEI table was corrupt because it kept restarting!? ....

Why is this process so cumbersome in 2017? Why do manufacturers not allow enduser UEFI level patching of all sorts?

@futiless

Hey,

Why don't you start your own dedicated thread about whats going on and we will try to help you out.. Little confused about what is the disfunction with your board..

Perhaps you should take it to stock firmware and settings, and if its not working RMA the thing..

Sorry I should have clarified any attempts I have made to utilize UEFITool in an effort to remove limitations like AMIBCP64 or Intel ME kit have failed. This likely I have read on these forums is due to the fact that the Aptio V high end desktop boards are limited to UEFITOOL due to graphics and enhancements I assume. So I am back here again and again. I have tried 20 times or more with each of these tools. Each time I get an error 94 debug after successful flash. This is even without making changes what-so-ever and just saving back to CMOS to see if output is functional. IT NEVER IS :( . This is the problem. I wanted to use UEFITOOL as it seems for us APTIO V, people on these boards. There is no other way ?! ...

I can use UBU and flash as you have mentioned before as this is a green light. but the goal is BIOS modding past these blocks; or perhaps further understand the beauty of UEFITOOL.

You see I really need to adjust my fans as they are relayed 10 feet to 18 140mm case fans on a radiator. The board badly needs to be further adjusted with a fan offset that I can see toying with me all the time in the hidden RC menu that I now can access very nicely thanks to Intel ME toolkit, NOW if I could only flash and make it bootable :! :(. ! You see the computer detects the rpm value at 10% due to my build being setup like this and sharing the line. and I can see the feature for offsetting the fan values right there !!! I need to be able to access these menus or I will always just see them on my desktop and waste time attempting it over and over. Here and there ad nauseum.

Thank you all again

@Fernando ,

Was wondering when it comes to Asus Cap files If I remove the Capsule in Uefitool will Usb Flashback method still work? Or should I just do my mods leaving the cap file in place?

Thank you..
