No, the exe still didn't work. All the other tabs have multiple different settings available in them. I haven't really played around with them to do a full verification, but everything seems to be available. Just the Intel tab is empty. I attached pictures of the updated bios and updated Cpu microcode. I can't thank you enough. I couldn't have done it without you. you did an amazing job.

Yes, as mentioned sometimes in there my goal was finding and enabling recovery and security, so sometimes 00's were places I was skipping over.
Just remember, not every file I posted was meant to be a used file, some were only so we could test/find this or that, and some things we tried many ways and never got, those may have been left in as we moved along due to either trying something else in a rush and forgetting to go back, or wanting to change direction etc.
Put it all back to stock and enable only those you want.

Ok, thanks for confirming. I just wanted to make sure that I am not missing anything in figuring the right string. So, basically I will be rather confident now to figure and search for the string for any other system.

I am not going to make the string correction for the two extra 01's in the BIOS of the other laptop for now. If I need to create a new mod for any purpose, I will then incorporate those changes. Yesterday, I created a BIOS mod for that system to expose Intel ICC Clock settings. I flashed it and after I made some changes in ICC clock, I got a blank screen. I was really scared. I searched about it and found in notebookreview.com that the ICC Clock region of the BIOS of this laptop is buggy. And the solution was to take out the CMOS battery and place it again. This revived my system. After that I flashed the BIOS which you last provided me and decided to do no more flashes on this system.

My Samsung Laptop BIOS is also finalized on my end. As I learn about FIT Table correction and Microcode update, I will do one final flash on that laptop as well and be done.

All the risky things will be carried out on the desktop system. I am just waiting for the hardware programmer to come.

@mikeshutte - You are very welcome! I wonder what's going on with the EXE? Must be some default check I can't see to disable? On the menus, there is always/usually some/many hidden sub-sections or sub-menus that can/require further enable via setting "User" in AMIBCP, only this time we can't see to verify which of those are what.
I could send you an IFR text file, that you could dig through, and see what settings and sections are shown there vs what you can see in BIOS, but that will take you a lot of tedious time doing, but if you want that is one way you can check.
I will be doing that for the Intel section, but that's just one small section, so not a huge task. I'll let you know what I see there, might not be anything useful. If you want the full setup IFR text let me know I will upload for you to dig through.

* Edit - here is all that's in the "Intel Section" Not much, if you want we can remove this menu, or you can leave as-is, or I can see if I can enable for you. I can try, but unsure? It's not same/as easy as this menu unlock, have to try to do all settings one by one - we'd start with one and stop there if we couldn't get after few attempts
Security -
Unlock Setup Status
Unlock Setup << This is for setting password on BIOS settings or entry, and next few items same
Admin Password Status
Set Admin Password
System Password Status
Set System Password
HDD Password Status
Set HDD Password

Set Service Tag
Password on Boot
Computrace - deactivate, activate, disable
HDD Security Configuration
HDD Password CONFIGURATION
HDD Password Status
Unlock HDD / Unlock HDD and Disable Disk Password
Set HDD Password

@akm - Yes, sorry if any leftover non-functional edits are there, we did so many attempts and sometimes I did, or meant to and forgot, go back and disable things that weren't working, but it's possible that sometimes when I jumped forward to new mod I grabbed old unfixed version to start on next round. If you want it all with only working 01's there, put back default and then edit in 01 one at a time until you have only the correct menus showing. Glad you made it through your scare there! Yes, anytime you set a BIOS setting and it fails to boot, or reboot etc you can always clear CMOS and be back to fail safe defaults again (Load optimal after that). That's why I said when we were discussing the graphics card enabling, it would be OK, if it failed you could clear CMOS and all would be back again.

Happy I could help you learn some BIOS modifications! I will work on small guide for microcode update and FIT table correction, but I kind of hate to post one here since there is already a sticky'd guide encompassing both

If it's not too much of a hassle for unlocking the Intel tab settings, that would be great. Otherwise don't worry about it. Definitely if you could post that Ifr file I'll dig thru it and see what I can come up with! But like I said, if the Intel stuff is a hassle, don't bother. You have done quite a bit already. Yeah the exe keeps giving the same error, can't flash the same bios version. But it's easy enough flashing with afuwin.

No, it's not a huge hassle, we can just try a few things and if no luck then we can remove the tab. There must be some setting I'm missing in the EXE, wish I knew which one for later, usually most people can't even redo the exe's, so I like to surprise and sucks when it wont work properly
Here is the IFR text. You'll have to go slow, to scroll past crap that is not relevant and look settings, write down ones you need but don't see in certain sections etc. All "Tabs' are starting with "Form: Name of tab" - example Form: Chipset That way you can recognize what section you are in.

Will get you a test BIOS soon as I have a chance for initial Intel setting test.

@Lost_N_BIOS Hi, I have been looking forward to your guide. While you create one, will it be possible for you in the meanwhile to do the Correction in my finalized BIOSes for the two laptops? I have played with all kinds of settings in the BIOS for both laptops and subsequently finalized these. Can you please correct both BIOSes?

Hey @akm - I am working on it now, sorry I forgot since I said I really didn't want to since there is already a guide here about it, and then you never mentioned again, so I forgot.
I'll make one now, but will leave out in-depth explanation on hex editing steps, will describe briefly, but guide will expect reader to already know how to use hex editor. Hope that is OK, if not let me know and I will try to think of a way to add that in too.

#188 RE: Accessing Locked BIOS Menu Settings Inspiron N5050 by akm 12.10.2018 10:05

Yes, that is fine. If I find any difficulty, I will ask the specific questions then.

Thanks, I thought about how to show hex edits with images, but it's cut and past this way or that way, so really no way to "Show" that in images for a guide.

#190 RE: Accessing Locked BIOS Menu Settings Inspiron N5050 by akm 13.10.2018 10:23

Even if images cannot be created, a simple text explanation may also help. Or maybe through an example, you can just show images specific to that example only and that should probably give me an idea.

@Lost_N_BIOS Did you mean to say that it would be difficult to create a guide?

It's time consuming yes, especially while helping in threads too, but I've already started so will finish, please be patient and thanks

And yes, it's not easy to create a guided steps on what I mentioned you quoted, it's copy/paste this way or that way etc, so that part will not be very will guided

@akm - uploading and formatting guide now, sorry for the wait! I only fixed single BIOS P770ZM8M.01-F.rom, that way you can use guide and start learning on the other one
https://www.sendspace.com/file/md2ehy

Will update the microcodes in the Samsung shortly too, or do you want me to wait and see if guide helps you get that one updated now too?

Here is guide - [GUIDE] Update CPU Microcode + Fix FIT Using UEFITool / Hex

#194 RE: Accessing Locked BIOS Menu Settings Inspiron N5050 by akm 18.10.2018 16:46

Thanks a lot for creating this guide! I will be trying out myself to update the BIOS of both the laptops using your guide. If I get stuck anywhere, I will ask questions. I will update soon.

#195 Help yo unlock BIOS hidden settings in my Samsung RC530/730 by Haplo 18.10.2018 20:46

Hallo all an thanks in advance,

the last BIOS file for my Samsung RC530/730 AMI BIOS APTIO 4 is from 2012, and there are not more updates from Samsung . So I decided to try to unlock the BIOS hidden settings, to see if I can get a bit more performance.

I have trying to unlock my hidden settings, without result. I can flash my modded BIOS without problems (in fact, I ha flashed it a lot of times trying to get some result), but only 2 or 3 hidden options appear in the new menu.

I have modded the BIOS with AMIBCP 4.53, changing ALL the options to USER (and they are a truly lot of them). Even I can see in BIOS the Intel Management menu, but fully empty . I have looking at several posts in the forum, specially this one:

Forum post

Ther problem is that I do not believe to be the same problem, and I am not very sure if following all the steps in that post I would get the best. All I have tried is:

- I have updated my BIOS , all I could with UBU, even micro codes



- I have extracted the "setup_extr.txt" with AMI Setup, and I did not get any warning about mi BIOS to be locked
- I have flashed it with AfuWin and AfuDos

At this moment I am without more ideas, so I have decided to ask to the experts , to see if I get some help... This is my modded BIOS and my setup_extr

06WD_modded.rom
Setup_extr.txt

Thanks
