  • Getting Legacy ATI Mobility Drivers working on Windows 8 x64

    I'm going to keep this one short and sweet. Windows 8 throws up a ton of new hurdles around getting old drivers to work, especially video card drivers. On top of that, some of the tools used to help make these drivers work on WIndows 7 and earlier have been broken for a while. So here's how I got the ATI Legacy Graphics Drivers working on my ATI Mobility X1600 on my Acer Ferrari 5000.

    1. Download the ATI Legacy drivers (x64 | x86). Install them, going all the way until they fail.
    2. Download the ATI MobilityModder and install it. When it is finished, copy this patch to "C:\Program Files (x86)\MobilityDotNET".
    3. Run the MobilityModder from the Start Menu, then select "C:\ATI\Support\10-02_legacy_vista32-64_dd_ccc" as your location, and let the Modder do its thing.
    4. Open an elevated Command Prompt and type the following commands:
      1. bcdedit /set {current} testsigning on
      2. bcdedit /set {current} nointegritychecks true
    5. Close the elevated prompt.
    6. Click the Start Menu and type "gpedit.msc" and hit enter.
    7. Nagivate to "User Configuration (2nd node) | Administrative Templates | System | Driver Installation | Code signing for device drivers"
    8. Enable the policy and set it to "Disabled".
    9. Restart your machine.
    10. When it comes back up, navigate to "C:\ATI\Support\10-02_legacy_vista32-64_dd_ccc\Packages\Drivers\Display\LH6A_INF\CH_95951.inf"" right-click it, and select "Install". You will get the familiar red dialog warning you about installing unsigned drivers. Throw caution to the wind and continue.
    11. Move your mouse to the bottom right corner of your primary monitor, and right-click. Select "Device Manager" from the menu.
    12. Expand the "Display adapters" section. You should see "Windows Basic Display Adapter". Right-click it and select "Update driver software".
    13. Click select "Browse my computer for driver software" and then "Let me pick from a from a list...".
    14. Lo and behold, your driver should already be there, along with the "Basic Display Adapter" option. Select it.
    15. Marvel as it installs.
    16. Enjoy your native laptop resolution and secondary monitor, profit, etc.

    HTH. Thanks to a post by Lars Michelson for the help in finding the MobilityModder patch.
