@sagael - We already have decrypted BIOS, your dumped BIOS from #23 - Ask Serg008 if he can get "SetupUtility PE32" from that BIOS
Why would he mention "Bin is wrong"?? Maybe he thought you were trying to recover BIOS with these? If so, yeah, I tell you that too, should not be used for recover.

H2OUVE and H2OFFT are very different, FFT made your BIOS dump, we need to find working/compatible version of UVE to get NVRAM variables to edit, and setup variables to use to make that edit (Both of these can be done with UVE, once we find compatible version)

Ahh, great! Those are not messed up like your dumped one! I can get setup from there, but we don't know which one applies to your system, unless it shows you the family ID in BIOS main Page or during BIOS update process.
Check BIOS Main Page, and or run BIOS update again, do you see either one of these values >> 01847F2A, or 0188DF2A

Never mind, I checked both BIOS, and there is no video memory, DVMT, etc option. So you cannot adjust this setting on this model.
Here is both BIOS setup in IFR form, so you can search, scroll through etc all the settings and see what I mean, no such setting here
https://ufile.io/zs678waw

https://fotos.subefotos.com/1ba64bb56987...d0daf9f217o.jpg

the system board is 1848 I suppose it is this 01847F2A , looking in APU options there is one in pci to leave it fixed in 64 bits could serve, PSPP Policy set it in Performance since the dpu is the only one that occupies pci express,disable Link ASPM

I think that the dgpu could be left as primary but it would be more risky

@sagael - Hmm, usually it would match, you don't see a system or family ID when updating the BIOS? I did find matching 01847.bin in your dump and that BIOS though, and it's not in the other once, so I think you're right
I don't see 64MB anything related to video size in any of the APU GFX or GPP Features, so you'll have to be more specific - Give me the exact setting name/names of what you want to change and what you want to change them to.

So far >>
PSPP Policy - Change to Performance 0x01 (Default/current = 0x03, confirmed in NVRAM/VSS - Custom+Setup - A04A27F4-DF00-4D42-B552-39511302113D)
Link ASPM, you'll need to be more specific, there is x7 of those. Give me the >>> VarStoreInfo (VarOffset/VarName): 0xxx << Of which you want to change

As for changing GPU defaults, here is my general warning for everyone when I give them unlocked BIOS Menu on a laptop, so probably best you leave that kind of thing alone
*** 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)

Please don't send PM's for help on BIOS edits, I can't help with BIOS in PM's. Please make a thread and I will try to help as soon as I can - thanks!
If you appreciate my efforts and are willing to donate to help improve my hardware, gift cards work for me (Amazn, NuEgg, eBa) - send me a PM

PCI Latency Timer has nothing to do with changing dedicated memory. Plus, what you said to set 64 - 0x01, is the default already (Confirmed), see default there
GPP enabled we can do

So far, here is list to change
PSPP Policy - Change to Performance 0x01 (Default/current = 0x03, confirmed in NVRAM/VSS - Custom+Setup - A04A27F4-DF00-4D42-B552-39511302113D)
GPP Enabled - Change to Disabled 0x00 (Default/current = 0x02, confirmed in NVRAM/VSS - Custom+Setup - A04A27F4-DF00-4D42-B552-39511302113D)

Anything else? If not, then follow this guide to learn how to use RU program - Go to section 2.2 and make bootable USB with RU program, then read 2.3-2.5
http://forum.notebookreview.com/threads/...-issues.812372/

You May not be making changes in "Setup" as that guide shows, it could be called "SystemConfig" and or "Custom" you will make edits in >> this GUID A04A27F4-DF00-4D42-B552-39511302113D
There should be both Setup or SystemConfig AND Custom, with this GUID, you need to make the same changes in BOTH

Changes you requested above are the following
PSPP - 0x155 >> Change 0x03 to >> 0x01
GPP -- 0x156 >> Change 0x02 to >> 0x00

If you are not familiar with hex, to get to 155/156, go down to line 150, and then out to column 05/06 this = 155/156

Please don't send PM's for help on BIOS edits, I can't help with BIOS in PM's. Please make a thread and I will try to help as soon as I can - thanks!

Thanks for the help, it would be all I do not see more gpu options in the BIOS, send me the file to test it

again thank you very much hope this is enough

@sagael - you're welcome. Sorry there is no option to make the DVMT change you wanted
Not sure what you mean about sending you file to test? You make the changes yourself directly as outlined above, there is no BIOS flashing here (unless you have flash programmer, then we can, send me dump and I will edit)

No, the above has nothing to do with flashing or programming BIOS. This is method to directly change current BIOS contents/settings value in NVRAM/VSS area of the BIOS.

@sagael - In USB Config, can you see and set "USB BIOS Support" to UEFI, or only enabled/disabled?
Some systems in UEFI Mode you have to wait a minute or two for windows to load, screen is black otherwise, this due to outdated GOP
Same may cause it to not be possible to use BIOS or DOS when in UEFI Mode, can you see BIOS or DOS while in UEFI Mode?

it only has uefi or legacy mode does not say anything about usb only the boot order, leave the screen for several minutes never gave an image not even through vga or hdmi

I have to configure uefi from win 10 as indicated here?
