You did try to download drivers from lenovo site and install them but shit(!), software installer says that “I have no idea about your operating system”.

Here are the instructions (applies Soundmax, no idea about Realtek (Xavi reported it works for Realtek too, thanks Xavi!)):

1. Don’t worry. :p
2. Download driver.
3. Installer will extract the package the path you choose (default is C:\Drivers\WIN\Audio).
4. Open Device Manager.
5. Go to “Sound, video and game controllers” section.
6. Select currently installed device and right click.
7. Select “Update Driver Software”.
8. Select “Browse my computer for driver software”.
9. Select “Let me pick from a list of device drivers on my computer”.
10. Click “Have Disk” button.
11. Select the location where you have extracted package (#3) and browse “<path>i386\Vista” folder (amd64 for 64bit).
12. Select the inf file.
13. Click “Next”

And you are done!

This applies to Windows 7 and Firefox 3.52. I don’t know it works on other versions.

If your Firefox redirects localhost to www.localhost.com and makes you crazy follow the steps:

• Open C:\Windows\System32\drivers\etc\hosts and remove “#” from “127.0.0.1       localhost”. Don’t forget to open file with administrator rights otherwise you cannot save it. If  you can’t find the way, copy the file to desktop, edit and move to the original location.
• Open network connection properties and disable IPv6

Don’t install any software if you don’t need it

If you wanna install Apache (or any other software which listens port 80 by default) on Windows 7 be sure those following services are stopped or not installed:

• SQL Server Reporting Services (MSSQLSERVER)
• SQL Server Integration Services 10.0

Don’t forget to set “Startup type” setting to “Manual” or “Disabled”.
