Final version of Windows 7 is done and it seems that unlike Vista this OS will be a huge success.
There are so many reviews praising this new operating system from Microsoft and everyone is so excited about it. Computers that had very hard time running Windows Vista do not have to be replaced or trashed as W7 should run quite well on it.
There is however one big issue – Windows 7 no longer supports XDDM drivers as Vista did. Instead it just uses the ‘Standard VGA Adapter’ which is good only for standard resolutions. And critical thing for notebook users – it does not allow you to hibernate or put the computer to sleep. Many great Centrino notebooks were shipped with i855 or i915 chipset and integrated graphics that do not support Aero. In Vista it was possible to use XP drivers and everything was fine, but in Windows 7 this no longer works.
Since I really wanted to use Windows 7 on my ThinkPad X40 (i855), I spend hours searching the internet for solution. And I succeeded! This is a step-by-step guide how to make it work:
1. bcdedit.exe -set loadoptions DISABLE_INTEGRITY_CHECKS
2. bcdedit.exe -set nointegritychecks ON
3. reboot to safe mode
4. open Computer Management, update driver for the Display Adapter using THIS drivers (only this version works!)
5. wait for the succesful installation message, reboot in normal mode
6. wait for the ‘New Hardware Found’ dialog to finish, it should give you error for one of the adapters
7. reboot to normal mode
8. wait for the ‘New Hardware Found’ dialog to finish, it should be successful this time
9. reboot to normal mode
10. change the color depth to 32-bit
Please note that I wasn’t the one who found out how to do this and I don’t want to steal credit for it. It is a compilation of various solutions I found on the internet that for some reasons didn’t fully work for me.
