[REQUEST/HELP] GA-H170M-DS3H - IGD Aperture Size

[hope__silent]

Hello Bios-Mods,

I'm looking for help adding a selection in the chipset section of this bios to adjust the IGD Aperture Size, which is hardcoded currently and is not adjustable or viewable in the bios settings. Ideally, I would prefer the option to simply type in the amount of memory I would like to allocate between a minimum 128mb or maximum 4096mb. However, a gradient of settings could also work: 128MB, 256MB, 512MB, 1024MB and 2048MB, etc. I'm not sure what is possible, fairly new to bios modding but comfortable flashing, etc. This motherboard does use an AMI bios, last revision 22e, dated 2018/03/09, here is the link.

Thanks for any help in this endeavor.

Well, I flashed modded rom and reboot was fine. I see new options in graphics configuration, Aperture Size, 128/256/512/1024/2048. Setting 2048 immediately falls back to 1024, setting and saving 1024 has bricked bios? Stuck on error "BLInitiatilizeLibrary failed 0xc00000bb".... Should I pull CMOS battery? Link for original chipset tab screenshot.

"BLInitiatilizeLibrary failed "you can google get more informations .
It seem cause with memory setting.
You need to debug ans testing self ,i can't help you as well.

Only adjust option will not bricked .
Bricked bios = bios can't boot normal as flash failure or flash a bad modded bios.

Well, I pulled CMOS and reset bios, tried setting 512 and same lib error. Pulled CMOS again, tried 128 and it boots. So it appears the mod is the issue or a more physical limitation of the chipset, no higher than 256mb? Unless you have another idea, I have another motherboard/cpu, an Asus H370M if you'd like to try on it?
