I was trying to unlock the hidden Advanced Menu, and I read about replacing the security menu button but I couldn't figure out the procedure. could someone explain in a step by step process how to this? I've found guides on unlocking basic menu's with AMIBCP, UEFI editor with HXD, but NOTHING on how to replace a menu with another one. if someone could either give me a step by step explanation OR do it themselves and then explain what they did it would be great! Thanks.

So after reading some more and exploring the hex code/IFR dumps I decided to try swapping out my Security menu
with the hidden advanced menu, which from my understanding should be {0F 0F 1D 00 1E 00 03 00 00 00 FF FF 00 0B 04}.

I tried replacing {0F 0F 1D 00 1E 00 03 00 00 00 FF FF 00 0B 04} (my security setting) with that address, and while it did rename the Security option to Advanced, clicking on it nothing.

So then I tried replacing Intel Rapid Start Technology with it, because its a setting inside of the normal advanced menu.
Replaced {0F 0F 57 0E 58 0E 5F 00 00 00 FF FF 00 4C 05} with {0F 0F 1D 00 1E 00 03 00 00 00 FF FF 00 0B 04} once again, and got the same result.

Also tried changing all of the settings inside of the hidden advanced menu to user with AMIBCP to no avail.
So now my BIOS has three advanced settings, two of which do nothing.

Is there something I'm missing?


Attached another stock BIOS image which I took after resetting factory settings.

Posting this cause file limit size on second upload.

Heres the modified BIOS I wound up with after attempting to hexedit.

Please edit your posts if you want to add more info and no one has replied yet, thanks

Please flash back in stock BIOS using normal MSI procedure, then do the following -

Check BIOS main page and see if ME FW version is shown, if not then download HWINFO64 and on the large window on left side, expand motherboard and find ME area, inside that get the ME Firmware version.
Once you have that, go to this thread and in the section "C" download the matching ME System Tools Package (ie if ME FW version = 10.x get V10 package, if 9.0-9.1 get V9.1 package, if 9.5 or above get V9.5 package etc)
Intel Management Engine: Drivers, Firmware & System Tools

Once downloaded, inside you will find Flash Programming Tool folder, and inside that a Windows or Win/Win32 folder. Select that Win folder, hold shift and press right click, choose open command window here (Not power shell).
At the command prompt type the following command and send me the created file to modify >> FPTw.exe -bios -d biosreg.bin

Right after you do that, try to write back the BIOS Region dump and see if you get any error, if you do show me image of the command entered and the error given >> FPTw.exe -bios -f biosreg.bin

If you are stuck on Win10 and cannot easily get command prompt, and method I mentioned above does not work for you, here is some links that should help
Or, copy all contents from the Flash Programming Tool \ DOS folder to the root of a USB Bootable disk and do the dump from DOS (FPT.exe -bios -d biosreg.bin)

sorry I couldn't figure out how to get both files attached due to the file size limit.

What do you mean both files? I only need your stock FPT BIOS region dump, after you've reflashed the stock BIOS from MSI again, is that what's attached above?
You can upload files to any free file host you want and then post a link here. I use tinyupload most often, it's free and no waits to download.

that IS what is above. what I was referring to when I was talking about multiple files was when I was making multiple posts to upload the files previously. My bad. but yes the stock FPT bios region dump is what is attached.

Ohh, OK, I gotcha now! Thanks for FPT dump, I will work on this soon. MSI BIOS often strict, like locked to certain menu counts due to limited space where this coding is changed, do you care if I have to replace security with chipset?
It sounds like you found a thread where we discussed and did similar mods to other MSI BIOS previously

Is that your desired goal here, Chipset + Advanced, or do you only really care about the hidden advanced? If you only need hidden advanced that's a no problem easy switch.

I definitely do not care if the security tab gets replaced. and yes that is the desired goal but if it'll take longer to swap security menu with the chipset menu that is NOT a big deal, whatever is less work for you :). thank you.

Thanks. It's not about longer to do both, just you may need to replace some menu with chipset - doing either mod is same to me time-wise so no big deal either way.
I'll check it out now and let you know what I think needs to be done.

* Sorry, I forgot to ask, we may not even need to use FPT. Were you able to flash in your previous mod attempts using M-Flash from within BIOS? Often you can do this with MSI, provided mod BIOS is same name as stock BIOS (extension too)
When you did the FPT Dump, right after that were you able to write back the biosreg.bin file as I suggested for testing?

no we didn't try using M-Flash, we flashed it booting from a usb stick with freedos and using AFUDos. and yes we were able to write the biosreg.bin file back without any issue.

That's not good method, lucky it didn't brick. M-Flash should allow it, sometimes not but that's rare.
Please test if you don't mind, that way I know if I can mod stock BIOS and have a unlock BIOS here for everyone, or if I have to unlock your FPT dump only which will be only for you to use and anyone else wanting later will have to request new mod again.
Thanks for confirm on BIOS region write without issue.

Can you please zip a few images of your BIOS for me, I forget what these look like and need to see the layout, what's visible in stock as far as Main, Advanced, Boot, Save and Exit etc.
You can probably F12 screenshot to USB - I found two from a sale when I had this board. Please show me what all submenus are visible for you in the "Settings" section, this is where I'll swap advanced and Chipset/security (if necessary)

M-Flash didn't work I got this error https://i.imgur.com/TgtJo9u.png
and there isn't a "select one file to update BIOS" option.

and the screenshots of the BIOS are in the attachment.

You need to use full mod BIOS, not FPT modified region. Were you using fill 8MB stock BIOS (Modified), and then renamed exactly to stock BIOS name.extension (E7850IMS.4B0)?
Make sure you have view file extensions enabled, that way you can see the actual extension and not just an extra .4B0 in the name and not the actual extension. To know you have it enabled, any text file will be filename.txt always, you'll see .txt on all text files if it's enabled
If it's not, then you can't see your mod BIOS extension name and you have E7850IMS.4B0.4B0 instead of E7850IMS.4B0 possibly

The "Select One File to update BIOS" option is blocked suppressed and removed from setup (as is a third option too), lazy engineer left that error message there for you.
So, stock BIOS update option can only do ME+BIOS (entire file BIOS Update). Please be sure you are using the stock BIOS from MSI, modified for some single BIOS edit change (maybe change a single setting with AMIBCP) then test again.

* Edit - do you have flash programmer? If not, I'll have to see if I have one of these boards around here still, this BIOS is more of a mess than usual for MSI
** Edit 2 - Ahh, I don't have one anymore, but I do have MSI H97M-G43 which I "Think" has similar BIOS layout, let me get that setup and do some testing before I send you anything, unless you do have programmer then no worries.
*** Edit 3 - @nover - yes, that board has same base BIOS, so I can do all mod/testing on my end before giving you anything, meaning all will be sorted here and you wont need to test this, test that etc before I get to a final unlock for you.

Please wait!

I used the original bios file from MSI, edited it with AMIBCP enabled Enhance Turbo and M-Flash let me flash it successfully and it's working. sorry for the misunderstanding. I do not have a flash programmer unfortunately. and thank you, I don't mind testing things at all though if you really need it.
