Hi ,
pls help, unlock my hidden advanced settings. i tired to try .but not get.
your help and guide much appreciated.
Thanks in Advanced

My bios dump file and original bios attached.

sahaf: It's me, i forgot to sign in to forum. so showing guest.

Do you have flash programmer? If not, how are you planning to flash the mod BIOS? I have not looked at your BIOS or files above, just asking if you already know how to flash mod BIOS on this system or not
You need flash programmer to write in mod BIOS on this model. You can however do the grub stuff you were trying with H2OUVE instead probably, dumps your vars.txt with both versions of this tool (leave files in place, and send back to me)
Then tell me what all variables you want changed, and what you want them changed to

Select the folder that directly contains the H2OUVE.exe in each version folder, hold shift and press right click, choose open command window here (Not power shell).
At the command prompt type the following command once for each version >> H2OUVE.exe -gv vars.txt
Then send me the package back, leaving all files in place, so we know what version created what vars.txt

Please edit your posts if you need to add more info or thoughts etc, don't make multiple posts in a row if no one answered, it makes a mess. Thanks

I sent you both 100.00.16.08 + 100.00.9.2 already So not sure what you are talking about above?
Or, do you mean the one 100.00.16.08 I sent you errors, but the same version from bios-mods works? If yes, please link me to it to download, maybe I have bad copy?

Anyway, downloading attached files from here is a mess, please upload back the package to me as I mentioned, with vars.txt in place in each version folder that made it.
This way there is no mistakes made when writing back.

There is no editing .fd with EZE here, it's not possible to flash mod BIOS like that. You must dump with flash programmer (like CH341A + SOIC8 clip with cable), or we can change settings with vars, that is all.
Unless you want to do pinmod (Like short while powering on)? See here, "E.1" for info on how to do pinmod
[Guide] Unlock Intel Flash Descriptor Read/Write Access Permissions for SPI Servicing

Otherwise we can only change settings in place, Tell me exactly by name, or what variables you want edited, and what you want them changed to and I will edit vars for you, then you flash it back.

If you do pinmod, then without a reboot, you must dump FD (Flash Descriptor) with FPTw, then edit it, then flash it back. Then you can reboot
See section "B" Spoiler #2, image #1 or #2 in the link above. Edit FD per one of those images, whichever looks like your FD, then flash it back.

Here's how to use FPT to do the above

A reply is required... I asked a lot of questions there

I am a beginner, sorry for my mistakes,

i already quoted , H2O zip inside separate folder vars files as per your instructions (pls check sub folder)>>> Attachment 1

Attachment 2 > H20UVE_100.00.16.08 <<< working one >>>>[yours one corrupted] .

# My understanding wrong .fd with EZE

#I want unlock advanced tab : your help needed !

#Pls suggest good way .
How do you do with vars ?
I already attached vars files[h2o zip insides]

#Grub method not working , i already try .Result: can't set variable via efi Error 0x00000000008 .

#I get infomation from Fpt info.
Error 316: Protected Range Registers are currently set by BIOS, preventing flash access.

# Error 316, Means/? I can't write via flash program ? <<<pls clarify .

# my needs, Advanced Tab with remove speed limiting my M2- NVME

#change XMP profile

Thanks, I will check files tonight and get back to you. Also, thanks for fixed H20UVE_100.00.16.08, not sure what happened to the one I sent (it's been working for some systems, maybe there is two versions w/ same version #)?

I only wanted vars to change any settings you need changed, like you were trying to do over at BIOS-mods. For me to do that, you need to tell me exactly what settings you what changed, and what you want them changed to.
If there is a grub variable that unlocks advanced menu for your exact model great, tell me that variable and I will change it for you.
Otherwise, to normally get advanced unlocked you need to dump BIOS with programmer, then I edit that and you program back in (ie getting unlocked advanced isn't normally something you can do by changing a variable with grub or UVE)
I see on that thread at BIOS-mods, "Something" is unlocked with a variable on one specific 592f-xxx model (not all). It's also not shown or discussed what actually gets unlocked with that edit, unless I missed it What is your full model?

Error 316 means you cannot flash with FPT without first having dumped the BIOS, removed the FPRR/PRR lock, and then programed back in (Then after that you could use FPT)

Please explain in more detail >> Remove Speed limiting your NVME. What do you think can be changed, this is limited by PCIE lane width and PCIE Type (2.0/3.0)
What is your current lane width and PCIE type? You can check with CrystalDiskInfo, in middle area on left side, if you need image let me know
Change XMP >> To what, or XMP 1 or XMP 2?

My model acer aspire VN7-592G- 72D3 .
Main model VN7_592G only . 72d3 sub model number.
why, i want unlock bios hidden menu?
My laptop m2 ssd (sata) inside (original from manufacturers)
I update m2.Nvme not detect . (But slot support nvme).
So, i try unlock bios advanced tab menu.
But, the reality i boot from m2.ssd success , without unlock bios (big story).
##
Now, my ram auto configured xmp 2.0.
I need this one changeable menu , switch xmp 1.0 , sometimes off. Some lagging in ram profile xmp 2.0.

This option available in i-page . In advanced tab.
##
Now my expectation unlock advanced tab menu.

My try Story 2:
I already open (extract ) my original bios from acer .
Use tool UEFI TOOL , IFR extractor
and check my i-page setup utility variable.
0x258 0x0 .
I want enable 0x1.
I try with grub 2.0xxx (boot via pen drive efi shell)
I got error ; can't set variable using efi ! Error 0x0000000008

Final: i really confused , which one correct method.
Your help much appreciated.and thanks for faster reply, and detailed explanations.
Current my laptop configuration.
My ssd m2.nvme : Adata xpg 256gb .
PCIE 3.0 x 4 . - 8GT/S .

How to back up bios. Incase stuck @boot , how to restore?***

@sahafdeen - Sorry for delayed reply! Before I answer above post >> The H20UVE_100.00.16.08 you included at post #10 is exact same one I sent you originally (hex match for both the exe and the .sys file)???? S
o, same/same, must have been corrupted download if one I sent you didn't work, that's only thing I can see here.

To your first comments, yes, I understand why you would want unlocked BIOS menus, but this has nothing to do with NVME.
Maybe your NVME mod was not done properly, thus you cannot find NVME during install attempts.

With unlocked BIOS, you could only enable XMP or not, possibly you could choose profile 1 or 2, if your memory has two profiles programmed.
This change can be made with vars dump or grub/setup_var edit too, without mod BIOS. Same as changing that variable mentioned for the i-page

What is set in "Setup" is not always what is used by BIOS, usually the applied setting is in NVRAM, this is why you use vars or setup_var edit to change variables usually.
Since you can't use setup_var for many variables here, you must use UVE dump vars, edit, then program back (or edit NVRAM directly in dumped BIOS, program back)

So you want Following? We will change directly with UVE vars edit
0x258 >> i-page changed to enabled - OK
0x2FB >> Memory profile >> Set to XMP 1 or 2?

I can't tell for sure how to unlock BIOS menus for you on this model, sorry. That is something they do best over at BIOS-Mods forum
I can however, make any hiden setting visible for you in sections you can already see. Or, as mentioned above, I can help you to change any setting (hidden or visible) via vars edit.

Thank you so much !
H20UVE_100.00.16.08 may be corrupted dl...

0x258 >> i-page changed to enabled . Its show or hidden. Still doubt .
I afraid edir vars UVE brick bios !
If you support how to to_do with safety guide . I try.
Tq

@sahafdeen - You're welcome

0x258 >> i-page << Yes, I mean change to whatever was not default, so if default is hidden, then I change to show

Edit vars does not brick BIOS, I do it often. I will do the edit for you, then show you how to flash it back.

If you want to do the edit yourself, that would be risk of bricking BIOS, in case you don't get it correct you know
Sorry, I do not know any guide for this, I can explain it to you once I make the changes, then you can compare before edit / after edit vars-mod.txt and see what I mean when I explain.

0x2FB >> Memory profile >> Set to XMP 1 or 2?
