I do not believe this is due to mcode, the base patch released by AMD should be intact used by OEMs, ill point this to “OS features abandonware” and consequently modern ACPI/DSDT and all users should expect this to continue in modern hardware platform releases, there’s no “gains” in supporting old OS for consumer market when the OS manufacturer already dropped support for it and keeps pressing forward.
You’ll have a chance with this only from a user with spare time and a very good knowledge of AMD DSDT AML/ ACPI FADT tables…
Read some topics on ACPI specs revisions and their implementations vs OS support…you’ll get the picture.
Here’s just a taste of it with easy understand of it.
My advice is to get an old platform hardware mb as spare system to your needs, regarding W7 OS, good luck.
I would like to point out that I AM currently running Windows 7 64-bit on my comuter rig at the moment, but this is on a Ryzen 2600 (Pinnacle Ridge).
To reiterate, as soon as I swap or change the CPU to a 5950x (Vermeer), it will fail to boot, nor will it execute a Windows 7 x64 installation disc or USB (unless it was a Gen2 release, which seems to use a Windows 8 setup style installation GUI).
It is for these reasons, including @Fernando’s assessment AND an Asrock tech support representative who also speculates that it’s to do with AGESA code, that I believe this could be a microcode problem
To avoid any misunderstanding: This does not mean, that each mainboard manufacturer compiles its own microcodes. The only difference between the mainboard manufacturers is the intensity, frequency and duration of the tests done with various BIOS modules.
This is a continuation from my ongoing problem which I’m following up from here:
(you can read if you wish to understand the full story)
Since purchase a few Asus x570-F motherboards and another 5950x, in hope to get this working again.
I have tried booting into my original Windows 7 64-bit hard drive, but no success.
It freezes on the Starting Windows animation.
Trying to install a fresh copy of Windows 7 on a spare drive, does not recogise Keyboard and Mouse.
Tried installing using Gen2’s ISOs. While that did install, once again it freezes on Starting Windows boot-up animation.
Did replace ACPI.sys with modded version (through Windows 10 as main OS and Windows 7 hard drive as slave) in their respected directories. No luck.
I was wondering if I might be missing something here?
Because I’m sure these motherboard were meant to be compatible and have used suggest methods described on these forums.
Once again, I would REALLY appreciate the help…I just want to have Windows 7 64-bit on my 5950x (is that too much to ask for?
Edit by Fernando: Thread title shortened and customized
Since I am pretty sure, that it is not your currently in use specific AMD X570 chipset mainboard with its specific Ryzen CPU, which is responsable for your problems, but a general mismatch of the desired very old Windows OS Win7 x64 and the quite modern AMD X570 chipset. That is why I would rather like to merge the content of all above listed new threads with >this< already existing one, which has been started already in December 2020 and may cover all your problems and their solution (if possible at all) as well.
For the interested Forum members and visitors it is much better to find all topic related contributions within 1 single thread.
Please let me know whether you agree with me or not.
Indeed I started those threads and whilst they do share somehting in common, the purpose of the topics are to serve different questions, and I feel it should remain separate for now.
I say this because another user of the internet who may have either similar or exact problems like myself to be able to search and read these topics more easily, and keeping it like this would be more accessible, rather than reading a merged topic with hundreds of post, it’ll alreday be overwhelming and off-putting.
I want people to resolve their issues as efficient as possible
On the other hand your test results seem to verify, that the manufacturer and the model of the X570 chipset mainboard doesn’t matter regarding your problem. Furthermore I bet, that a solution (if ever will be found) will be valid for all systems with an AMD X570 chipset and a 5000 Series Ryzen CPU.
By the way:
Forum users, who have a similar problem, are interested to read the solution, but not several threads and hundreds of posts about the problem.
You cannot continue your tests with the ASRock X570 Pro4 mainboard, because you obviously have bricked its BIOS.
>This< thread about the same problem has been started 4 years ago, but we haven’t seen yet any solution. If you should find it with your new ASUS X570-F system, all affected users of an X570 chipset mainboard will be happy to read your report!
Do you really mean the C5 state? Within the BIOS of my X570 chipset ASRock mainboard I only found the option “USB Power Delivery in Soft Off state (S5)”.
Is it this BIOS setting, which should be enabled?
@lvpha
I am not interested in getting Win7 installed onto my X570 chipset system, but if you should have meant S5 while writing C5, you should correct your typo.
Try downloading using this link: Link removed by Fernando
Yes, for the first time. You have to boot into Win10 first.
Sometimes the system still freezes on boot. I have to reboot it like 2-3 times before I see the mouse and keyboard lights on.
Edit by Fernando: The download link to a cracked Windows ISO file have been removed, because such links are a clear violation of Microsoft’s Copyright and not allowed within this Forum.
@lvpha Well, download completed and went straight to installation.
Of course created USB boot with Rufus on MBR mode.
And besides for everything being in German, I was able to navigate and it looked very promising.
However problem occurred yet again…when installation was completed and was rebooting (again) to start windwos, I was stuck again here (but in different language )
I have now gone through a week with no productivity!
I don’t know (again) where to continue with this, as I just find it really strange that I’m getting almost exactly the same response with my (now bricked) Asrock x570 Pro4 motherboard…it just doesn’t like like botting into Windows 7.
Can anyone give me some suggestions perhaps?
Also, where does one obtain a Windows 7 ISO with modded Acpi.sys?
