The problem isn't the AMD driver
but Toshiba themselves. From the release notes for the latest (and any version for that matter) of Catalyst,
he following notebooks are not compatible with this release:
- Any notebook launched after this driver release
- Switchable Graphics enabled notebooks.
- Toshiba® notebooks (please contact the notebook OEM for driver support for these notebooks)
- Sony® VAIO® notebooks (please contact the notebook OEM for driver support for these notebooks)
- Panasonic® notebooks (please contact the notebook OEM for driver support for these notebooks)
Toshiba for whatever reason will not allow the install of the reference AMD (or Nvidia either) video drivers
, and only allow the install of drivers from them.
That isn't to say that they can't be made to install. No guarantee that it will work (it should), but if you're up to a little challenge you can modify the INF in the AMD driver and it should then be able to install. A few relative easy steps is all it takes,
1. Download and begin the install, which will extract the install files to C:\AMD (unless you deleted this folder, you should still have it).
2. Go to the above folder and locate,
C:\AMD\Will be the name of whichever Catalyst suite you downlaoded\Packages\Drivers\Display
and open the INF (C7132079.inf is the one from the current mobility Catalyst) in Notepad.
3. Next open Device Manager and locate your video card. Open the properties on it and click on the details tab and locate the DevID. It will look something like this,
the part you're interested in is bolded.
4. Back to the INF and locate one of the following,
"%AMD9552.1%" = ati2mtag_M9x, PCI\VEN_1002&DEV_9552
"%AMD9555.1%" = ati2mtag_M9x, PCI\VEN_1002&DEV_9555
"%AMD9553.1%" = ati2mtag_M9x, PCI\VEN_1002&DEV_9553
"%AMD9480.1%" = ati2mtag_M9x, PCI\VEN_1002&DEV_9480
"%AMD9488.1%" = ati2mtag_M9x, PCI\VEN_1002&DEV_9488
and change one of the DEV numbers above with the one from your card. (the Mobility HD4650 is also known as the M96, just not sure which of the above would be it).
5. Now run the install again using the setup.exe in the first folder. If it installs you should get the warning about the driver not passing WHQL, just click "install anyway" as the change you made is what broke it.
