 I Introduction, DSE and cookies

-----------------------------------------------------

1. What is UnifL?

Universal Driver set for all Switchable Graphics (Intel HD/HD2000/HD3000 Graphics) powered laptops, based on latest versions of ATI and Intel drivers.

Main advantages:

- Always Up-To-Date Drivers.

- No dependency from your official notebook manufacturer.

- Can be installed on clean system i.e. “from scrach” without problems.

- Automated and reliable workaround to install modified drivers - DSE.

- Detailed manual, which covers all you need to know about Leshcat’s driver sets.

- Automated cleaning system called YUC, which saves your time and nerves.

2. Why aren’t Leshcat’s drivers signed with WHQL certificate?

In an attempt to make money, Microsoft prohibited loading of non-signed drivers in Windows Vista and 7. Since certificate’s cost is big (and a new one is needed for any new version of driver) manufacturers chose not to update drivers, if no fatal flaws are present. It wouldn’t be so bad if not for video drivers - new versions of which are released regularly, and they often contain performance improvements and bug fixes. Consumers with Switchable Graphics notebooks were left without updates for 8-9 months! Time to change this.

Leshcat created his own driver sets, based on latest Intel&AMD drivers. The only problem was driver signing, but it was effectively dealt with.

3. How does DSE helps solve signing problem?

Featuring "DSE" app:

For pretty long time i was getting complains about Ready Driver Plus app, that its slowing down loading of the system, in some cases wount work or its presence just gets people annoyed.

For me its was barely acceptable solution as well, but at past time it looked the best available.

 At some point, i 've decided to discover new way to beat the "modified drivers limitation" on x64 systems, that would be simple, non-time consuming and reliable way to replace RDP.

 My search resulted in "DSE" - "Driver Signature Enforcer" - simple application, which will enable installation of modified files* on x64 without affecting performance or exposing itself.

 In other words - you won't feel the difference between normal system and system with "DSE" installed.

I want to bring to your attention, that:

1. Featured and all future releases will require "DSE" to be installed 1st in order to function properly.

2. "DSE" has to be run only ONCE in your system.

3. "DSE" will not affect installation of official drivers or system performance.

 Of course, "DSE" will automatically locate and ask to uninstall RDP before in order to avoid possible ( &impossible ) conflicts. After RDP is gone, you can proceed with installation. Don't forget to reboot when promted.

 Also "DSE" has an ability to run one of my packages after successful installation.

 Just put AMD \ Realtek current set of mine next to "DSE" installer and rename it as "setup.exe" and check the box in "DSE" while installing it.

From 11.11, DSE is integrated into the main package.

4. Installation of DSE is simple. Just follow these steps:

1) Download DSE from 4Shared:

2) Check if UAC is off:

Head into Control Panel and type UAC into the search box, or do it from the start menu. Then drag the slider down to the bottom.

Don’t forget to reboot after disabling UAC!

3) Launch DSE as admin:

4) Click “Next”:

5) Accept the license agreement:

6) Select, whether you want to remove watermark and/or launch external driver package (setup.exe, must be located in same folder). “Disable Driver Signature Check” checkbox is mandatory for Leshcat’s Drivers to function:

7) Review your selection, then click “Next”:

8) Reboot when prompted:

Once again: From 11.11, DSE is integrated into the main package.

5. DSE de-installation

If you want to uninstall DSE for some reason, follow these steps:

1) Run “Cmd.exe” with administrator rights.

2) Enter the following command (Without quotes!): “bcdedit /set {current} TESTSIGNING OFF”

3) Reboot.

 II Pre-installation procedures

-----------------------------------------------------

UNIFL 12.1 and higher have integrated cleaning system, called YaD’s UNIFL Cleaner or YUC. Use it, instead of Driver Cleaner - it cleans SG drivers better!

It can be accessed by pressing “YaD’s UNIFL Cleaner” button on main menu:

After that, you have to read license and accept or decline it:

Make sure your ATI card is active or PMD (For Sony users only) is plugged in. Also, make sure your antivirus is disabled:

If you answer “Yes”, you will be presented with the Main Menu:

Every option has a tooltip, but i will explain each one in details:

Silent mode: YUC won’t show any promts/messageboxes - ideal for “Black screen deinstallation”. By default, log won’t be sent to me.

Send message: overrides “Silent mode” - log will be sent to me, in full-auto mode.

Check number of videocards: YUC will check number of videocards on your system.

Create restore point: YUC will create a restore point at each run, just-in-case.

Rescan: Do not use it on main system! Will force Windows to install standard drivers before first reboot, effectively eliminating the need for second. Breaks some notebooks (Acer 3820tg, Lenovo 460/560, etc), considered experimental. Do not use it on main system!

Please note that system will reboot automatically, so save your work and close all programs which contain unsaved data, before pressing ok.

After first reboot, cleaner will load once again to continue cleaning. Reboot after second phase completes.

After cleaning, go straight to chapter 3.

Sometimes, YUC fails to delete drivers from normal mode. Hanged ATISetup, agressive monitoring utilites, which are using ATI files are the cause. I this happens, you have to remove drivers manually, as shown in the next 2 paragraphs.

1. Old driver removal

Go to the Control Panel, and delete drivers using Programs and Features. Delete “AMD - Catalyst Install Manager” (and “Intel HD Graphics” if present).

2. Cleaning remains of old driver

This step is optional. We recommend to clean only if you have experienced problems.

Drivers are very complex programs, and they are not perfect. Sometimes, when upgrading driver, AMD installer malfunctions, and installs some driver parts incorrectly. It may lead to unexpected behaviour of any kind.

Driver Sweeper is a program for driver cleaning, developed by Phyxion.net. It will eradicate any AMD/Intel driver remains, which were left after normal uninstallation.

To clean your system, follow these steps:

1) Download Driver Sweeper and install it.

1.1) If you installed version 3.20 or earlier, download Filters.xml and put it in Driver Sweeper’s root directory. Default one is “C:\Program Files (x86)\Phyxion.net\Driver Sweeper”.

2) Reboot to safe mode by pressing F8 before Windows logo appears, then choosing “Safe mode”. Log-on using an account with administrator rights.

3) Launch Driver Sweeper.

4) Select “AMD - Display” and “Intel HD Graphics”, then click Clean.

5) Press “Ok” when prompted.

6) Press “Ok” again.

7) Go to device manager, “Video adapters” section. If something other than 2 “ Standard VGA Graphics Adapter” is there, right-click that device/devices, choose “Remove” and select “Delete drivers” checkbox if present.

8) Run "addon_remove.reg" file (it will clean configs of  AMD and Intel).

9) Reload (look picture) Device manager. Now you should have clean 2 “Standard VGA Graphics Adapter”.

10) Reboot into normal mode. Reboot again if prompted.

This steps will erase all important files and settings about previous driver. It’s time to install new ones!

 III Installation

-----------------------------------------------------

1. Unpacking:

1) Download and run Leshcat’s latest driver set as admin.

2) If DSE is not installed, unpacker will ask if you want want to install DSE. Press “Yes”. You will be able to unpack and install set even if you press “No”.

2.1) Press “Ok” and wait for DSE installation to finish.

2.2) Choose whether you want to launch unpacker after reboot or not.  Please note that reboot will occur regardless of your choice.

3) Click “Next”, read AMD release notes.

4) Click “Next”, read Intel release notes.

5) Click “Next” again and read Leshcat’s release notes.

6) Select unpacking location, click “Next”.

7) Now you’ve need to choose whether you want to install “AMD HDMI driver” and “Intel Media Additions”.

AMD HDMI driver” is needed for HDMI audio to function.

IntelMedia Additions” are needed for Quick Sync and other Intel HD Graphics 3000 features to work. Install them if you have second generation i3/i5/i7 processor. Here is the list of Sandy Bridge (Second generation) processors.

Click “Next”

8) Select, whether you want a desktop icon for AMD installer or not.

9) Review your selection, then click “Next”.

10) If unpacker asks you to delete previous unpacked set, click “Yes”.

11) After unpacking finishes, choose “Launch AMD installer”, or do it manually (Launch Setup.exe in the unpacking location).

Now, to the final step. Let the installation begin!

2. Driver installation.

1) Launch AMD - Catalyst Install Manager, choose your language and click “Next”:

2) Choose “Install”:

3) Choose “Custom”. Do NOT choose “Express”!

4) Select components to install. “AMD Video driver” and “Catalyst Control Center” must be chosen.

Features like HydraVision are optional and are not shown on included screenshot:

5) When “Windows can’t verify the publisher of this driver software” prompt appears, choose “Install this driver software anyway”:

 6) Wait for installation to complete.

        6.1) If everything went smoothly and Catalyst Install Manager reports success, press “Finish”

        6.2) If this warnings occured, click “View Log”:

If the source of the warning is already installed “Microsoft Visual C++ 2010 Redistributable”, and “AMD Catalyst Install Manager”, “AMD video driver” and “Catalyst Control Center” “Final Status” field reports “Success”, like in screenshot below, then everything is okay and you don’t need to worry.

6.3) If error occurred, like in screenshot below, - go to chapter V.

----------------------------------------------------

IV Troubleshooting

----------------------------------------------------

If driver malfunctions (i.e. broken YouTube videos or inability to switch graphic card), you can force it to reload.

There are 3 ways to do this:

1) Log off/Log on. It will force ATI driver to reload.

2) In device manager, under video cards section, disable both video cards, then enable them. It will force complete reload of both Intel and ATI drivers.

3) Reboot. Simple as that.

If nothing helped, go to the next chapter.
