@Lost_N_BIOS hmm mate are u still up for it? :)

@haudegen1993 - Sorry for the delay! Please test in following order, once new menu appears stop, no need to test further (ie if #1 shows menu, that's all we needed )
Flash via >> FPTw.exe -bios -f filename.bin
https://www.sendspace.com/file/0hdsql

1. biosregM2B
2. biosregM4B

*** WARNING - To ANYONE with laptop and unlocked BIOS!!!! ***
DO NOT try to enable this graphics card or disable that card, switch cards etc. Otherwise you will end up with no display output (ie black screen) and no way to recover except by blind flash or with flash programmer.
You can change graphics related settings, like changing memory sizes, or core speeds etc, just don't try to disable one card or change which is main etc.
Additionally, be very careful when trying to undervolt CPU, you can leave BIOS unbootable due to CPU voltage too low (Sometimes even 0.05 is too much)

*** WARNING *** - This BIOS is user specific! If you are not user haudegen1993 at Win-RAID.com forum, DO NOT USE THIS BIOS!!
If you do, and you are not haudegen1993, then you will loose your serial, UUID, OG NVRAM, and possibly LAN MAC ID as well.
You have been warned!!!

Tried both of them, but didnt work :(
At the try of biosregM4B.bin the last line is:
RESULT: The data is identical.10240KB of 10240KB - 100 percent complete.
heres the full result of the flashing process, maybe it ll help u?

Hmm, that can't be right, unless you first saved some BIOS with that name (ie forgot to use -f first)
Download the package again, and try >> FPTW.exe -bios -f biosregM4B.bin once more (Don't use -d ever here), there's no way it's 100% match to anything.
Actually, that is what it says every time at end of flash, sorry got confused there for a second But, it doesn't look right, there should be more changed bytes that what's shown there.

Also, before you do that, flash M2B first again and show me the output like above, it looks like it may not be flashing in all the changes

In case this is happening, and it's not flashing in the volume we're actually editing, please flash back your original FPT dump (latest one - ie file in post #29), then do below after rebooting
FPTw.exe -a 0x620000 -l 0x420000 -d VolMainDXE.bin

Then I will make you new edit to flash in using this method instead

@Lost_N_BIOS
Downloaded the new version (r27) of intel csme and extracted your files directly into it, so there are only 3 files in win32 folder now
Flashing biosregM4B.bin:

there are no changes too - so i wrote back the original biosreg.bin, which needs more time, and this is the output result:

OK thanks for your report , i understand the image file attached to #9 post wont work as intended.
now we'll try another method. i found this(below) in setuputility module and i think we can directly make hidden menus show up easily.
0x17EAEB One Of: Setup Menu Insyde Full Show, VarStoreInfo (VarOffset/VarName): 0x133, VarStore: 0x1234, QuestionId: 0xD1D, Size: 1, Min: 0x0, Max 0x1, Step: 0x0 {05 91 61 16 62 16 1D 0D 34 12 33 01 10 10 00 01 00}
0x17EAFC One Of Option: Hide, Value (8 bit): 0x0 (default MFG) {09 07 63 16 20 00 00}
0x17EB03 One Of Option: Show, Value (8 bit): 0x1 (default) {09 07 64 16 10 00 01}
now please find some usb drive and put grub efishell into it , boot to grub and enter "setup_var 0x133 0x1" (without quote) then press enter and reboot.now check your BIOS to see if hidden settings show up.

It worked
After reboot I had the hidden menus :)

glad to know this method works. good job!

@Blossomcrown - Thanks for jumping in here to help! I was gone for a few weeks, and then of course everything I was in the middle of helping with was long past buried
My inbox is still a scary place

@haudegen1993 - Sorry I lost this thread for so long, but glad to see you found the help you needed via easier route
