[REQUEST/HELP] Gigabyte B360 HD3P modify Aperture Size

[ambyjkl]

Hi everyone!

This is my first time BIOS modding and I'm looking for some help. I want to modify the "Graphics Aperture Size" of the onboard graphics on my Gigabyte B360 HD3P. Unfortunately, the settings does not have any way for this value to be customized.

Here are some references on what this setting does and how it works:
https://www.techarp.com/bios-guide/graph...ture-size/
https://www.intel.ca/content/www/ca/en/s...ivers.html

Here's a link to the latest version (F13) of this BIOS, which is based on AMI V, released on 2019/06/27 https://download.gigabyte.com/FileList/B..._f13_n.zip

By default, this motherboard seems to set this value to 256MB, but I would like this bumped up to at least 1024MB and as high as 2048MB.

As a first-time BIOS modder, it would be a great learning experience for me to do this on my own with your guidance, but if you prefer to do this yourself, you are very welcome, any form of help would be highly appreciated.

Thanks

You could find option "Aperture Size" in Chipset tab.

You could find option "Aperture Size" in Chipset tab.

Unfortunately, like I mentioned, there is no such option that can be configured in the BIOS, which is the problem I want to solve. Either:
- Unlock said option so it can be configured
- Hardcode needed value so it's always set the way I want it

Ok ,i see.
Use this tool to backup current bios and attach it.(Run dump.bat as administrator).
I would try edit it.

@genius239, you're a genius indeed, it worked like a charm . Check your paypal, enjoy the 20 bucks i sent you .

Something I found interesting is the 2048M option doesn't work: it fails and falls back to 1024M. About your request for me to test flash the F13 bios, I should have mentioned earlier, but I'm on Linux, so I used a tool called flashrom instead of the Efiflash.exe you sent me. I actually don't have access to windows on this computer since it's a remote server which comes with linux, hence there is no way for me to test Efiflash.exe for you, sorry about that :/

Good news~~i'm glad this modded can help you.

About Efiflash.exe it should be run in dos environment , so you can make a dos bootable usb device t ,boot this device then going to dos .

I'll see if there is a way I can get into a dos enviroment, and let you know how the flashing goes.
