I recently got an ASUS GL504GW, and I'm trying to enable the other menus. So far, I've followed Lost_N_BIOS' posts, but I think I've missed something.

I've done the following:
Disabled BIOS Lock
Dumped and verified I could flash with FPT for v12.
Showed menus with AMIBCP.
Found magic string, and modified it to show the menus.
Reflashed modified bios.

The OEM bios file is available at https://www.asus.com/Laptops/ROG-Strix-S...pDesk_Download/ .
I've uploaded my (mostly unmodified; I've only set BIOS Lock to 0x0) FPT dump https://cache.snorfi.us/l/h72b0p/biosreg.rom~WIN-RAID~cowpod-GL504GW.zip (it's to big to attach), but I'd prefer it if someone could point out what I've done wrong or missed.

@cowpod - There is newer BIOS BTW

Magic String is NOT used in this BIOS version/Type (this is Aptio V), generally that is only used in Aptio IV. So, undue any change you thought was magic string edit

First thing you need to do, without use of AMIBCP, is change these "Suppress If's" to False in Setup Module PE32 (Below is just one example, for Advanced and Chipset only, there are others suppressed, look at the IFR output)
0x282DA Suppress If {0A 82}
0x282DC True {46 02} << Change to False (47 02)
0x282DE Ref: Advanced, VarStoreInfo (VarOffset/VarName): 0xFFFF, VarStore: 0x0, QuestionId: 0x2, FormId: 0x2712 {0F 0F 1E 00 02 00 02 00 00 00 FF FF 00 12 27}

0x282EF Suppress If {0A 82}
0x282F1 True {46 02} << Change to False (47 02)
0x282F3 Ref: Chipset, VarStoreInfo (VarOffset/VarName): 0xFFFF, VarStore: 0x0, QuestionId: 0x3, FormId: 0x2713 {0F 0F 1F 00 02 00 03 00 00 00 FF FF 00 13 27}


Then, this BIOS needs "AMITSE" edit, "Like" (but not exactly) I show here in the "advanced spoiler" method * @cowpod - Sorry, forgot link! >> OverPowered TONGFANG CyberPower Machrevo MACHENIKE - Unlocked BIOS Guide W/ Files
The AMITSE menu stuff for this BIOS however is hidden in a fake AMITSE >> A2DF5376-C2ED-49C0-90FF-8B173B0FD066 >> Extract this PE32 Body, replace same way once done editing
Anyway, this and setup needs edited first and ONLY, then tested, BEFORE making ANY AMIBCP User/Super Access Level changes to main menu items at root levels.
Then, if Advanced or Chipset still does not show up after that, then you test AMIBCP User/Super at ROOT level on top of this and then it will show up

Hi, thank you for your reply!

I found the SuppressIfs in Setup PE32, and have modified them (there are a LOT. I've only modified the first "important" 5). However I can't find anything in AMITSE PE32 or A2DF5376-C2ED-49C0-90FF-8B173B0FD066 PE32.
As ifrextractor has more output, I've run both ifrextractor.exe and ifrextract.exe for all sections. (I'm not sure which I should use, so why not both?)

For "Section_PE32_image_A2DF5376-C2ED-49C0-90FF-8B173B0FD066.sct", I get ifrextractor "No string packages were found in the input file", and ifrextract "Protocol: UNKNOWN error: Unknown protocol".
For Section_PE32_image_AMITSE_AMITSE.sct, ifrextractor runs but only has file contents "HII string package: Offset: 0x28F58, Length: 0x415B, Language: en-US", and ifrextract runs as well but is effectively blank.

Thanks, and I've attached the section files below.

@cowpod - Do not edit unnecessary Suppress If's, only the one you want, otherwise you can end up with a mess or broken BIOS etc

I showed you above the exact edits (stock content then edit example) to make in A2DF5376-C2ED-49C0-90FF-8B173B0FD066 PE32 (This is "AMITSE" for this BIOS, lets call it Alternate_AMITSE, ignore the module called AMITSE )
IFR extractor is ONLY used on setup module, it's not used on GUID mentioned above (or AMITSE in other BIOS). This is hex editing file only, with information from setup, used to give you the info and examples above in spoiler.

If you want me to do the edits for you I can, just let me know what you want to do menu-wise. You can flash in setup edit only, but it's not going to make any of the hidden menus appear, this is controlled in the GUID I gave you above (Alternate_AMITSE)

Thank you for the offer and clarifying, I've got it working!

I've noticed that sometimes when exiting an entry, I am kicked to a blank screen. Then pressing UP arrow, it shows me a vertical list of all the menu entries, even the ones that are suppressed! It's kind of like a secondary backup method of reaching hidden menus.

Thank you so much!

@cowpod - Good to hear! About the blank screen, sounds like you maybe did some edit wrong.
Yes, sometimes BIOS Bug like you mention can do that about the hidden menu list, or it could be due to incorrect edit you made (making a BIOS Bug, so then show that)
If you want me to do the edit so you can test if it's same outcome let me know

I guess that would make sense... Please do edit so I can crc it!

What I've done is in Setup_PE32 set second and third SuppressIf=False, which I assume is what the bug could be; I might have changed the wrong items.
For ASMIT_ALT, as per your example I swapped Bad Advanced for OG Advanced (and hid the bad one), and replaced the blank slot with Chipset. I left chipset in the Blocked area too; should I have removed it?

@cowpod - Sorry, I forgot that above, thanks for mentioning, yes, chipset needs removed (zero fill line, move rest up) from that first area block list. I'm adding that edit to above spoiler now, so it's all there and proper

Suppress If changes only need to be done on what you are wanting to reveal. So what do you want done, my exact example above (swap Advanced menus + Add chipset)?

Yes, please just swap advanced and show chipset.

I'll redo the changes on my end so I can compare!

BIOS v306 dump: https://cache.snorfi.us/l/28rbfw1/biosreg.zip

OK, give me a bit, I was getting 305 ready for you, but we'll do 306 instead I wondered why you didn't update to 306 already

* Edit - @cowpod - Please test in the following order, STOP once you see new Advanced and chipset and let me know which files shows this (then rest, not needed to be tested or those kinds of edits not required etc)
1. SetAMITO << This setup and Alt_AMITSE edit only
2. SetAMITSDU << This Setup and Alt_AMITSE + AMITSE/SetupData edit ("AMIBCP" Access Level User, manually done, not using AMIBCP)
3. SetAMITSDS << This Setup and Alt_AMITSE + AMITSE/SetupData edit ("AMIBCP" Access Level Super, manually done, not using AMIBCP)

If #1 shows, then AMIBCP/Manual access level edit is not required, if it does not show at #1, then Access Level edit to User or Super is required
All mod files included, so you can compare stock/mod etc (Watch file types, I extract setup and rest differently as-is/body etc)

Modified Setup_PE32 extract as-is, crc32 matches your file.
Modified AMITSE A2DF5376-C2ED-49C0-90FF-8B173B0FD066 extracted body, crc32 matches your file (if I reorder the hex patches, and modify the end bytes of Short Entries).

I didn't need to do any AMIBCP! All I needed was Setup_PE32, and AMITSE A2DF5, and everything (I wanted to show) shows.

If a menu isn't shown in the list, would I then find it in IFR (eg "Overclocking Performance Menu" 0x2798/0x9827) and swap that into AMITSE with something else, then in Setup if it has a "SuppressIf" patch it?
And one more question.. can I not hide the old menus, ie. can I have two advanced menus at the same time?

Thank you!

@cowpod - You're welcome!! Great to hear your edits were match, AND that all you needed was the setup/Alt_AMITSE edits for menus to show up properly too!!
Now, anything (Setting or submenu) still missing inside currently visible menus simply needs AMIBCP like edit (AMIBCP or manual) to it's access level at it's root location (root of Advanced), and possible unsuppress edit if suppressed in setup
For example, the Overclock Performance Menu you wanted, nothing needs done in setup, only AMITSE/SetupData edit to change Access Level (or AMIBCP). Test User first, then Super if User does not work

Ahh! Never mind, I see "Overclock Performance" menu is outside of Advanced in this BIOS, BIOS is such a pain sometimes, this is a MSI move not Asus!
So yes, you would have to do what you mentioned in Alt_AMITSE only, using 98 27 - You can replace any menu you do not use, or do not change things in, all settings there will be left at their defaults (Such as boot or security etc, or if you do not need chipset you could put this in place of that instead)
This is not ideal though, but it will work. What do you need inside there, that's not already inside other menus in new Advanced or Chipset? I think all CPU related stuff is inside CPU Config or Power & Performance.
Ohh, I guess "Memory" stuff is there that isn't inside new Advanced or chipset.

Yes, you can hide old menu, put them in the block list (both, if room), they should be hidden now, but I/we didn't add old advanced to second block list, so may require simple User Access Level / Show Yes/Not byte change
So, if they still show up, Edit AMITSE/SetupData and change Access Level byte to one that = show/No (ie instead of 09, change to 08, or 01 to 00, if doing manually), or change the Show to NO in AMIBCP at the root level for that menu
If you need an example edit of this let me know, I will do it as a single separate edit on AMITSE/SetupData and show you (using Old Advanced as example)
Actually, here - compare with stock AMITSE/SetupData body and you will see the two bytes changed - http://s000.tinyupload.com/index.php?fil...348076910763269
You can use this file, it's only change is to hide default Advanced

@cowpod - See edits above

I've successfully enabled "Overclock Performance Menu"! As you said: all I needed to do was add it to AllPossible.
I removed entries that were in AllPossible and Blocked at the same time, to make some free space - there was a surprising amount of them - I still have a free slot for something..
It helped me to think of the sections as "Enabled slots" (All Possible), and "Disabled slots" (Blocked)..
Again, thank you for your help! I wouldn't have gotten anywhere otherwise.

@cowpod - Yes, sometimes there is duplicates in there, or ones not used, so you can make free space like you mentioned and did, creating more room too.
Good work figuring that out You're welcome!!!

This is probably a long a shot i don't know how to edit unlock or anything like that but would love to have the performance menu added. Same lap GL504GW. I've always built my own pc's for this reason I just currently had to have this cause my son going through a lot of surgeries for club foot so i moved to this instead for the long trips and stays. If not oh well if anyone wants to ty.
----------------------------

Also i have downgraded bios to 305 because i wanted to undervolt with throttlestop to lower temps.
