Good day, @W1zzard ! Sorry for such a looong reply, but finally I have the good news. Recently we got the Lenovo G505S discrete GPU working at coreboot opensource BIOS , with the help of these VideoBIOS ROMs : 1)...

https://unix.stackexchange.com/questions/119762/how-to-dump-memory-image-from-linux-system Even if somehow I manage to dump the whole 16 GB of RAM, I doubt they would contain a Video BIOS for discrete GPU : " cat /proc/iomem " shows only one "Video BIOS" there - which is for integrated GPU...

Most people are dumping it to mod to improve the performance of desktop's GPU or just to backup. But I plan to use this Video BIOS (AMD AtomBIOS) together with coreboot open source BIOS : https://www.coreboot.org/ https://www.coreboot.org/Supported_Motherboards This wonderful BIOS is fully open...

After a lot of researching I found this wonderful freeware tool: " Belkasoft Live RAM Capturer is a tiny free forensic tool that allows to reliably extract the entire contents of computer’s volatile memory – even if protected by an active anti-debugging or anti-dumping system "...

luckily the video BIOS of HD 8650G is smaller - 61952 bytes, less than 64K. meanwhile, for HD 8570M it is should be 33792 bytes and for R5 M230 - 32768 bytes, both are smaller than 64K So there is nothing wrong in at least trying to extract the video BIOS from these GPUs ;)

GPU-Z is it open source? Usually such utilities are open source and everyone can contribute As a software programmer I would gladly improve GPU-Z but sadly I can't find the source code

Please at least add HD 8650G to your supported GPUs list, like you have already added HD 8350G. Also it would have been super great if you could fix HD 8570M / R5 M230 detection and BIOS dumping

You are partially correct: at most laptops initially all the Video BIOS ROMs are a part of motherboard's UEFI/BIOS. But during laptop's initialization at startup: these "option ROMs" are loaded to GPUs after some modification (e.g. integrated GPU video BIOS is runtime patched by motherboard's...

Recently GPU-Z added the support for HD 8350G which is a part of A4-5150M mobile APU. but HD 8650G - a part of A10-5750M mobile APU from the same family - is still unsupported ! Also I have an access to a couple of AMD laptops which have HD 8650G as integrated with HD 8570M and R5 M230 as...
