Hello, just discovered this thread, in hope to somehow get Widows 7 to run on my new Ryzen 4000 Laptop.

Got this Laptop with a Ryzen 4800u (not yet delivered)

Is there any way so far, to get Windows 7 running on a Laptop with a Ryzen7 4000 Processor?
Could your Win7 ISO's work with it, or are there not the right drivers for this Laptop?

Thanks in advance.

I don't know, I don't have any information about that, I don't know what USB controllers laptops like those use.
I don't like Ideapads, they are garbage in terms of durability, but if you already ordered it I would recommend to just try it. Windows 8 from 2012 and younger will just use their built-in USB xhci drivers, so would Linux I suppose. An idea from me is that you use a DVD and try it on this way if your laptop has an optical drive.

Greetings Patrick

i slipstreamed these drivers into my installation media and was able to get win 7 working on an asus x570 board. however, the usb ports stop functioning on an msi x570 board. the drivers work during installation but i cant get past the first-boot name screen

Ok, and slipstreamed you the drivers into every of the needed indexes ?

yes, every install.wim index and every boot.wim index

Ok, an which version do you use? I ask this because there might be a patch needed.

i typically install pro. its just odd that it works on one x570 board and not the other

I mean what version from the driver, not Windows' edition.

the latest update that was posted in the OP

Ok, and what is the version number that you use? I am asking ebcause of the SHA256-Patch, don't forget about that.

i slipstreamed the patch but it didnt change anything. im thinking xmp was causing the issue

@onlinegravy I don't think that XMP would cause an issue like that, but what I know is that I don't recommend doing things like that at all. Reset your settings to default an just disable Secure Boot and disable UEFI boot, that should be it, it's better to give a success the best chance as possible. Tweaking is not helpful.

Hi, @canonkong
I have several questions.
Are B450 and B550 about the same? Are there significant changes in the B550 chipset USB controller?
Did you add only three lines to "amdxhc31.in"f? Or did you modify "amdxhc31.sys" drastically?
Which is the B550 chipset USB controller of 43EC,43EE and 43EF?

@isopc1999a
Yes，500s mainboards' USB ID have change，A520 is 43EC，B550 is 43EE，PRO565 is 43EF，they both from ASMedia 1142，what I need to do just remove the ID check in amdxhc31.sys and add ID into the inf.

@canonkong Excellent work!
I hope that Gigabyte or AMD will fix firmware bugs.
