#1 | [Request] Bios Menu Unlock for Alienware m15 R1 datum

Hello,

I'm trying to unlock the bios menu for Alienware m15 R1. I only changed some menu options from Default to User with AMIBCP and saved it as biosmod.bin (8mb) with the bios I get from "FPTw.exe -bios -d biosreg.bin". Surprisingly, the bios lock is disabled by default. I was able to dump the ME region with "FPTw.exe -d dump.bin".

Bios dumped with ME (16mb): http://www.mediafire.com/file/99es3b6exrhaj9h/dump.bin/file

However, after flashing the mod bios with "FPTw.exe -bios -f biosmod.bin", it does not boot anymore. I had to flash the bios back to original dump.bin with SPI Programmer to boot again.

I wonder if someone could help me take a look at what I can do? I attach both the dump bios and my mod with AMIBCP. Thanks.

P.S. Also, I dumped a rom file from another chip on the MB through SPI Programmer, CH341A, as dumpunknown.bin, which does not seem to be bios. I also found out I had to use setup_var_3 from https://github.com/datasone/grub-mod-setup_var to change hidden bios options in the meantime.

@Lost_N_BIOS would you have some time to take a look? Thank you.

Also this is the info from MEInfoWin.exe. I am not seeing any info about Boot Guard. Does that mean it's not enabled?

I also see that the Setup module is cyan in UEFITool with biosreg.bin. (8mb) Does that mean editing bios will result in brick?

The full dump (dump.bin 16mb with ME), however, does not show any color for the same Setup module: (Aren't they supposed to be the same?) Does that mean if I flash with the full 16mb with edited Setup module, the laptop wouldn't be bricked?

Zitat von Lost_N_BIOS im Beitrag How to extract contents of this Dell BIOS package?
@earthoo7 - Two PM's about this and you erased the post??! Do you still need help with that, or did you sort it out?

@superb123 - What did you dump the 16MB file with?
And yes, this is normal, sometimes if there is no BIOS/SMI/SMM lock on BIOS region, or system has FD/ME/Service etc jumper, you can dump BIOS region with FPT, edit, and flash it back.
What do you mean "restore" back to original? Sounds like a failed BIOS edit, so no changes visible.
OR, do you mean you see some kind of BIOS auto recovery? If yes, in that case, it could be failed edit and it soft-bricked so auto-recovery kicked in, or no edits are possible so that would always happen (Never seen with Dell, only HP)

Looking at another 8930 thread where I tried to help user - [REQUEST] Unlock options and Remove Dell SupportAssist detection from Dell XPS 8930 bios
We found Boot Guard was enabled, so any edit of the main BIOS region where you'd do menu edits cannot be done or = brick.
Please check with MEINFO and see if boot guard is enabled on your system, see end of the report from this command >> MEINFOWIN.exe -verbose
If you see Measured or Verified Boot enabled at left/FPF side, you cannot do menu mod or use AMIBCP etc. But, if needed, you can still change any setting, hidden or visible, via NVRAM edit
What is your goal here?

Yes, as mentioned many times over in this thread, the extracted files from EXE cannot be used directly to recover/rebuild a BIOS usually, at least not as they are or whole etc (you have to know what you are doing, extract and use only certain portions etc)
AMIUCP properly extracts this file It's just not something you can edit in AMIBCP as it is, can only be used to rebuild BIOS when you know what to do.
If you want to edit BIOS, you edit your FPT or programmer dump. But, do keep in mind what I said above, boot guard is probably enabled on your system too, so anything you edit in a yellow/cyan/red region will = brick (open file with UEFITool 51-57 NE Alpha to see these Boot Guard covered colored areas I mention)
This means you CANNOT edit this BIOS with AMIBCP, at all, anything you want to do in there is covered by Boot Guard and will = brick.

If you need to change some settings, give me a list of exact setting by name you want changed, and what you want it changed to, and I will do NVRAM edit on your FPT BIOS region dump above.
