Yes, I’ll help you. It’s simple.
can you do something on my computer to force the dedicated gpu or fix the memory of the vram? My latop is g4 2072la bios insyde f.2.a
Link bios https://ftp.hp.com/pub/softpaq/sp77001-77500/sp77491.exe
Sorry but no.
Did you see a private message from me? It says: "There is information about which module should be edited.
But, unfortunately, even if you unlock the bios, you will not be able to limit the vram of the igpu. In the hidden settings, there is no one with which you could do what you want". And it doesn’t depend on me.

in the ifr file I found this entry, will disable it force the DGPU as high performance?

@sagael
GPP’s are just 1-Lane PCIe ports. The performance of your dGPU is not limited by the BIOS, but it is controlled by the operating system settings.
@Sweet_Kitten , Sorry for the late replay but i have already ordered a spi flasher and a test clip from a Chinese store, so it might take a bit time to arrive.
But in the above link for $HS2 protection, is this for removing protection from my bios?
Ah, yes. This method is also suitable for your bios.
@Sweet_Kitten the dgpu stops working when I expand it from 4 to 8gb there is no way it works with 8gb and I used all kinds of amd drivers without success
can you send me the files in the attachment of this post? I didn’t understand what he meant by function code with the address 0x10000ac1.
But for the other method from this post I think I found the function inside F6B211E8-A3DF-41B3-89D5-BDBF6729255E module. (also thanks to this article by coderush)
I can’t because I don’t have access either.
The function addresses are on the left side of the IDE interface, but you won’t find AC1h. This is a different BIOS, different from the example given on the link.
Yes, but the method is very specific and probably won’t work. You already know how to check it. This red error message appears - everything is fine.
If you want to know about the method of CodeRush, then just compare the original module with the module from that BIOS in archive I uploaded.
Oh, alright. Then Ill use your bios mod for reference. But i cant fiind any tool to convert .fd to normal bin file :DDD
also another question, why does the red error appear ? is it beacuse the rsa check passed?
at first, when I saw it, I thought the bios didn’t install so thats why I got that error.
".fd" is just an extension. It doesn’t matter to our needs. The BIOS file becomes suitable for flashing using the programmer after using PhoenixTool on it. This will decrypt it.
The error message appears due to a special update mechanism. The reason for this error is that Hewlett-Packard has foreseen the possibility of a failure during the upgrade process. However, this had an impact on security. I believe that it was intended to pass the RSA check even if a copy of the Pre-EFI-Initialization volume(part of the BIOS containing the F6B211E8 -…) is broken. Therefore, both of them were left functional, but the identity of each other is still being verified. I don’t know how to make InsydeFlash flash all PEI volumes.

ok, so after decrypting it with phoenixtool and comparing that module, I found only one change of instruction and I applied the change. So, let me know if i missed something :)).
if this is enough, then I guess I can start to do the menu unlock, which I also dont know where to start xD.
Okay, Ill try to do this a bit later. But there is another idea I have in my head. Since the conditions are checking for the menu id, can we change the menu id to something random, so the condition is always false. like,
frommov ecx, 1DBh to mov ecx, FFFFh. In a sense it should work, right?
@1nxpired
Menus ID’s are actually ID’s of strings. But for what reason they go out of order like 1DBh, 1DCh…?
So this is because there are many strings of names between them. You are free to do whatever you want, but I will tell you what happens if you do FFFFh: in 1F7B9 byte string package of specifically your BIOS there are exactly 7E4h different ID’s, and changing to an incorrect one or going beyond the limits will give a black screen on startup.
@Sweet_Kitten I finally got my SPI programmer after waiting for so long. And with your mod it worked flawlessly ;DDDD
but now the problem is, I cant seem to be able change the configuration for ConfigTDP levels, it is hard coded to 15watts. Do you know any mod thats used to change these hardcoded values?

I have seen some threads about modifications of this kind. Unfortunately, I did not investigate how these mods was done, and now I can’t find any, so if you find one, let me know. I can’t figure out how to do this on my own. Ima stupod.
nah bro if it werent for you I wouldnt have still figured out how to unlock my bios. meanwhile, I found source code for insyde bios for some device. but I cant find anything useful because from the intel datasheets the ctdp registers are read-only for this processor so the bios only reads these values but doesnt have any functionality to change it. So, I’m kinda lost right now. I think I should create a new thread for this, maybe that will bring someone’s attention who might know how to deal with it.
hello, how did you release the advanced tab in the bios? Can you release the bios download?
