How to get drivers for older Mobility Radeon cards on Windows 8

    Relatively recently, AMD released a special driver package for Windows 8, AMD Catalyst Legacy 12.6 (a link to the news on the AMD website ), but it did not work on a laptop with Mobility Radeon HD 3400 (this does not mean that it will not work for you - check it out before proceeding with the procedure described in this topic).

    Having visited the site, I found that in the section of old mobile cards Windows 8 is not mentioned at all. You can get a driver for Windows 7. Do you need it at all, this driver from the manufacturer, if the eight has a built-in driver that works pretty well - you decide. But I’ll say right away that the Catalyst Control Center (a graphical configuration utility) cando not earn, alas and ah. How to get a driver for Windows 7, I'll tell you under the cat.

    1. We go to the AMD website and download the latest version of the driver for Windows 7 of your architecture.
    2. We open the installation of components (windows + X -> Control Panel -> Programs and Components -> Install Windows Components), select the .NET Framework 3.5 component (now it cannot be downloaded from the site, and by default it is disabled, it turns on that way. There is still quite an inconvenient way to install it offline, from the installation disk, if someone really needs it - I’ll try to remember and write in the comments).
    3. We are trying to install the driver downloaded from the AMD website. It should install without errors (according to him), but immediately after clicking the final OK, we understand that nothing has actually changed, the system still uses the driver from Microsoft. Important: although the driver didn’t work, installing it (or at least unpacking it somewhere on the hard drive) is necessary!
    4. Download and install the modder:
    5. If you run the modder now, it will crash for an unknown reason, no matter what compatibility options we set for it. Therefore, we download the file by reference, unpack it, and replace it with the exe file of the same name in the directory where the modder was installed: later.html .
    6. Yeah, now you can already run this executable, show it the path to the folder where the official drivers are unpacked (I have it C: \ AMD \ Support \ 12-6-legacy_vista_win7_32_dd_ccc_whql), click the modify button and wait a bit.
    7. Now we go to C: \ AMD \ Support \ 12-6-legacy_vista_win7_32_dd_ccc_whql \ Packages \ Drivers \ Display \ W7_INF, or where you unpacked the official drivers there. We see a bunch of files there. We are interested in those that end in * .inf, they can be installed. Installation is done by right-clicking on the file and selecting “install”. The names of the files in this directory may differ, for example, my driver was called CL145534.inf. And not all infs can be installed there, in my case CW145534.inf lying there was not installed. An indicator of a successful installation is the appearance of a dialog box with the words "successfully installed." If your driver does not want to be installed due to unsubscription, see point 8, otherwise skip it.
    8. This item is needed if Windows refuses to install the driver due to unsubscription. He will also reward us with the eternal inscription “Test mode” in the lower right corner of the desktop (if someone could tell in the comments how to remove this inscription, it would be gorgeous)
      1. We open the command line in elevated privilege mode (open the new-fangled start metro menu, type cmd on the keyboard, right-click on the "Command line" icon, select "run as administrator" in the pop-up menu at the bottom).
      2. We type the following commands there:
        bcdedit /set {current} testsigning on
        bcdedit /set {current} nointegritychecks true
      3. Click on the keyboard (windows button) + R, enter gpedit.msc there and press Enter. In the window that opens, go along the path User Configuration -> Administrative Templates -> System -> Driver Installation, in the right pane, double-click on the item “Digitally Sign Device Drivers”, select “Off” and click OK
      4. We reboot the computer and return to step 7. (Administrators and experienced Windows users here may recall that there is a gpupdate command and two spaces after it, allowing you to instantly update policies, so this will not work, you really need to reboot)

    9. Open the properties of the drivers for the video card. (windows + X -> Device Manager -> Video adapters -> Your video card (ATI Mobility Radeon HD 3400 Series) -> right-click and select “properties” -> Go to the “Driver” tab). Click the “Update” button, select the option “Search for drivers on this computer”, select the option “Select driver from the list of installed drivers”. There will be several drivers, including the one that comes out of the box with Windows - it will appear in the title line "(Microsoft - WDDM v1.1)". We do not need this one, we need one that is called your card, for example I have one: ATI Mobility Radeon HD 3400 Series. If there is nothing like that, go back to step 7 and look for some other inf that you forgot to try installing.
    10. After the reboot, make sure that the driver is really the same (open the properties of the video card drivers, as done in the previous paragraph, in the field “provider” the name should change from Microsoft to Advanced Micro Devices).
    11. We check that the Catalyst Control Center does not work (right-click on the desktop, the first item of the drop-down menu is just the Catalyst Control Center. After choosing this item, he thinks for a few seconds and then in a separate dialog box writes a message with the general meaning “I don’t know what configure, so I won’t start). If CCC works for you, be sure to write about it in the comments!
    12. We are trying to install again: . If it is established - we have to earn Catalyst Control Center. If not, well, at least we have a working driver from AMD.
    13. Enjoy.

    I hope this post was useful to someone and I’m not banned for a two-page footcloth.
