AMD Raven Ridge Ryzen modified iGPU driver for Windows Vista My modified driver inf for AMD Raven Ridge Platform is ready to be released and here it is! It supports Radeon Vega mobile graphics integrated with Ryzen 3 2300U, Ryzen 5 2500U, Ryzen 5 2700U. The driver inf file is my modified version based on a 21 december 2017 Windows 10 Acer OEM driver inf, but is used here to install a much newer Win10 driver from early 2018 with patches and fixes till 8 march 2019. Feature set: https://msfn.org/board/topic/186330-windows-vista-on-amd-ryzen-mobile-raven-ridge-vega-graphics-testing/?do=findComment&comment=1269617 Download: https://forum.legacydev.org/viewtopic.php?f=27&t=218 Installation process: Preparing drivers Install CFF Explorer and 7-zip Download the 2017 driver: https://www.catalog.update.microsoft.com/Search.aspx?q=22.19.655.5888 Rename the downloaded .cab to "2017.cab" Download the 2019 driver: https://www.catalog.update.microsoft.com/Search.aspx?q=23.20.826.9472 Rename the downloaded .cab to "2019.cab" Extract both with 7-zip to their respective folders called 2017 and 2019 Go to 2019\B340050 directory and locate all .sys files there. For all 3 files, open them in CFF Explorer, go to Import Directory and rename ntoskrnl.exe to ntoskrn8.sys. Then go to Rebuilder and untick Rebuild PE Header and tick Update Checksum, click Rebuild, than save. In 2019\B340050 folder rename coinst_17.40.dll to coinst_17.30.dll Go to 2017\B322218 and copy all files from there that are missing from 2019\B340050 to 2019\B340050 i.e copy all files from 2017\B322218 to 2019\B340050 but WITHOUT replacing. Clear 2019 folder from all files (inf and cat) that are not in 2019\B340050 folder. Download modified .inf file (if you haven't already) Put the modified file in the 2019 folder Driver should be ready, now let's move to preparing your system. Preparing your system Install x64 October 2022 Extended Kernel if you haven't already https://forum.legacydev.org/viewtopic.php?f=27&t=209 Download and compile George King's modified NTOSKRNL_EMU Extender https://msfn.org/board/topic/184042-amd-radeon-graphics-driverdriver-pack-for-windows-vista/?do=findComment&comment=1227975 https://board.eclipse.cx/viewtopic.php?t=404 https://github.com/GeorgeK1ng/NTOSKRNL_Emu Put the compiled ntoskrn8.sys into your %windir%\System32\drivers directory https://board.eclipse.cx/viewtopic.php?t=404 Open start menu, search for msconfig.exe and open it Go to boot tab and tick "No GUI Boot" checkbox, than click ok to save changes Installing drivers Install driver from 2019 folder using the device manager, confirm installing unsigned driver Don't restart when prompted yet Go to %windir%\System32 and rename atiumd6a.dll to atiumd6a.dll.backup Go to %windir%\SysWOW64 and rename atiumdva.dll to atiumdva.dll.backup Congratulations! Restart the PC, drivers should work on restart Known Issues Driver may hang on system bootup (hangs on around 1/5 of bootups). Not sure whether this is related to Ryzen Vista issues or the driver, likely not fixable with .inf edits. You may hear funny repeated startup sound chord when it does hang. After booting the OS is 100% stable from my testing, no gaming tests though. Feature set is limited, see feature set above Entering sleep mode takes around a minute Note that Ryzen platform can have BSOD issues completely unrelated to the display driver, read https://msfn.org/board/topic/186330-windows-vista-on-amd-ryzen-mobile-raven-ridge-vega-graphics-testing/ and think twice before buying Ryzen products just for Vista. But anyway if someone figures out how to solve all BSOD issues the driver is already there. Special thanks to: @win32 for the Extended Kernel @K4sum1 for Guide to getting AMD 17.10.1 drivers working on Vista @Cannonkong for MessageNumberLimit fix @George King for adding necessary features to NTOSKRNL_EMU Extender

I've decided to try out Windows Vista on AMD Ryzen 5 2500U, the Raven Ridge mobile platform. First drivers for their integrated GPU (OEM ones for Windows 10, not straight from AMD) predate 17.10.1 drivers which can be made to work on Vista: https://board.eclipse.cx/viewtopic.php?t=404 I've installed the OS (with Extended Kernel) on a VM and then applied vmdk virtual disk image onto a M.2 SATA SSD which was then installed in the laptop, and booted from it in Legacy/CSM mode Initially there were some BSODs, but they stopped occuring after I removed optical disk CD drivers from 'c:\Windows\system32\drivers' cdrom.sys and cdfs.sys. If you remember they where one of the causes of BSODs on Ryzen systems. The other one was of course USB controller, but it's clearly not causing issues here, bluescreens were significantly less frequent from the start than on my old Ryzen desktop and after removing those CD drivers stopped occurring completely and the system is fully stable now. Even USB 3 works with @cannonkong's modified drivers https://winraid.level1techs.com/t/solution-win-7-win8-1-x64-ryzen-apu-video-driver/34203?page=1 The only thing that doesn't work yet is the GPU. Is is officially only compatible with Windows 10 Redstone 1607+, but @cannonkong managed to get is working on Windows 7, 8.1 and 10 Threshold (1507 and 1511) with just an .inf mod. The oldest version of his modded drivers of from 2019 unfortunately so I tried applying simmilar patches to this HP OEM driver from 09.2017 https://www.catalog.update.microsoft.com/ScopedViewInline.aspx?updateid=808a5b95-4eb0-4be6-82f6-58fad73c2708 I succeeded for Windows 10 Threshold 1511, but on Windows 7 this driver launches successfully, but you can only see distorted image and then nothing on the screen. Despite that that system works, you can change backlight brightness click on things and hear sounds. This issue can be however completely fixed by going into sleep mode and resuming. The GPU works ok after that. On Vista the symptoms are the same as on 7, but sleep mode doesn't work, so you can't use this as a workaround. You can even see Aero working for a moment, and than black screen (you can still hear sounds and interact with the OS). So a simple tweak could make it work. Do you have any ideas? EDIT: I've tested system's stability without GPU drivers installed and it survived all 7 hours of testing, which included 2h of video playback (on Microsoft Basic VGA adapter) and also around 2h of web browsing, it hadn't crashed a single time. However when I started messing with GPU drivers, a BSOD caused by video drivers would often be followed by another one in a very early boot stage including when entering SafeMode, so I'm not sure anymore. Perhaps the potential for Ryzen-like BSODs exists, but after removing CD drivers nothing is using system resources in a way that causes BOSDs -
Lately I've been testing Windows Vita on AMD Ryzen mobile platform. https://msfn.org/board/topic/186330-windows-vista-on-amd-ryzen-mobile-raven-ridge-vega-graphics-testing/#comment-1269685 The OS is stable once it has booted so it's mostly usable, but this cannot be said about virtual machines running on this hardware. The stability is WAY worse there. It seems that Ryzen issues affect virtual machines running using AMD's virtualization technology way more that the host. Guest machines (Windows 11 and Linux) would randomly hang, endlessly display what was on the screen just before the crash and cause 100% CPU usage on cores that were assigned to the virtual machine. It doesn't harm the host OS, you can just run taskmgr.exe and close the affected virtual machine This makes me think Ryzen issues lie deeper than in the USB controller, CD ROM drivers and the likes. It may be related to no drift correction as on Haswell, I guess Windows build 6519 would have to be tested to know for sure. So far ppl have reported different builds to be the ones that fix the Ryzen BSODs https://board.eclipse.cx/viewtopic.php?p=2910#p2910
