Temporarily bypass Reduced Functionality to rescue your files and operating system capabilities and pave the way for a clean, genuine, windows install.

On the Windows Activation, click on Access your computer with reduced functionality option.

Once the Internet Explorer loads, click on File on menu bar and then select Open on the pull-down menu.

On the Open dialog window, type in C:\Windows\Explorer.exe and then click OK.

Click OK button on “IE needs to open a new window to open this webpage” confirmation prompt.

Click Run button on “File Download – Security Warning” dialog prompt.

Click on Run button on “File Download – Security Warning” warning dialog related to unknown and not verified publisher.

User shell will load, and the desktop, taskbar, start menu and etc will be restored.

The computer has recovered from Reduced Functionality for this session. To permanently stop RFM to happen again, Windows has to be rearmed.

Click on the Windows Start button.

Type Cmd in Start Search box.

A program shortcut will show up in the Start panel search results. Right click on the shortcut and select Run as Administrator.

In the Command Prompt window, type in the following command and then hit Enter: slmgr.vbs -rearm

Restart your computer.

Not only unsupported, Mobility Radeons are further crippled by their drivers. Laptop distributors (HP, Dell, Lenovo, etc) limit the clocks on the bundled video cards and restrict access to the GPU BIOS. There are a number of logical reasons behind this, namely warranty overheating issues.

There are a number of ways to work around these restrictions, the best likely being a BIOS mod, as it would allow fluent clock changing through ATT, or other programs. However, some GPUs have their BIOS read and write protected, making the process rather futile.

Another, simpler, method is using a specific driver version. 8.9 and 8.10 Catalysts allow you to overclock when used in conjunction with AMD GPU Clock Tool.

So before we begin, these are the ingredients you want:

*optional components

To begin, uninstall your current drivers. If you have the Catalyst bundle installed, go to control panel, remove programs, ATI uninstall – remove CCC, Install manager, and Display Driver, reboot.

If you are running Windows 7, load up DSEO and enable Testing Mode, reboot computer.

If you do not have an ATI entry to uninstall in remove programs then head over to device manager (Run “devmgmt.msc”), select your display adapter, right click on it and select uninstall. Your screen will probably flash.

At this point you have the option of booting into safe mode, by pressing f8 repeatedly in between bios loading screen and the windows logo, and running Driver Sweeper to wipe all traces of ATI from your computer.

When this is done boot back to windows and extract the 8.10 drivers you just downloaded. Now run Mobility Modder, point it to the ATI directory that was created, and click Modify.

For Windows 7, there is an extra step. Skip this if you are not running Win7.

Locate atikmdag.sy_ in the ATI folder, use

DSEO to sign the file.

Now go back to device manager by running devmgmt.msc , select your display adapter, and press Update Driver. Navigate to Browse fo r File, Pick from list of drivers, select Have Disk, navigate to the ATI directory which was created *\ATI\Packages\Drivers\Display\LH6A_INF and press OK.

You may be prompted whether you wish to install an unsigned driver, press yes. If you have Windows 7, you have one more step. Use DSEO to s ign the “atikmdag.sys” in your /windows/system32/drivers folder. Now you can reboot.

When windows boots back up, you can use the AMD GPU Clock Tool to change your clocks.

When installing ATT, make sure to check Disable Overclocking, as it will not function properly. Read these notes if installing ATT on Windows 7.

As stated earlier, Windows 7 requires digitally signed drivers. This is a bummer if you want to run an awesome application like ATT rather than crappy CCC. The fix, as you may have guessed, relies on DSEO. Download it, run it, agree to prompts, enable TEST MODE, and reboot.
Following the reboot, install ATT but do not launch it. Instead, head over to its installation directory and locate atitray64.sys and atitray.sys – these are the unsigned drivers.

Launch DSEO, select sign a system file, and manually enter atitray.sys and press ok. Do this one more time for atitray64.sys Now you can run ATT without problems.

Driver Signature Enforcement Overrider

Ati Tray Tools

Because Windows 7 requires digitally signed drivers PG2 will not work out of the box. But the information provided on PG2’s instruction page is outdated pertaining to the RC. The solution?

Check out our guide to an alternative solution.

Driver Signature Enforcement Overrider – a program by NGOHQ for dealing with this pesky annoyance. The recipe requires two ingredients: DSEO and pg2-rc1-test2.exe – Firstly you must enable TEST MODE in DSEO, and reboot your computer. Following the reboot, install PG2, but do not launch it; instead, navigate to its install folder (C:\Program Files\PeerGuardian2) where you will see “pgfilter.sys”. This is the unsigned driver, to sign it use DSEO’s sign file option, manually add the path for pgfilter.sys, and press OK. Now type “bcdedit /set loadoptions DDISABLE_INTEGRITY_CHECKS” in th e run box (start>run) without quotes. Now you can launch PG2 with no problems!

If you find yourself having to redo these steps every time you launch PG, check out Vista RC Loader.
