VERY IMPORTANT!!!!!!
Don't start messing with the file in Windows - The different character sets will mess up things...
OMG - it's 00:38 here and I'm finding it hard to concentrate... Wonder why
However I should think you would be able to make the runlevel change without further guidance...
Just open the initab file
Change id:5 to id:3
and save the file - USING KWRITE!!!! WINDOWS IS A BIG NO NO!!!
By saving the file as text just altering 5 to 3 all that should happen is that your machine will boot up in the command line instead of in the graphical desktop - Which is good
To get back into the desktop you'll have to write startx <Enter>
If that works there is one other file we need to modify and then the installation process can begin...
I'll post the name of the file and describe the changes you need to make there as well
After that I'll describe what you have to do to run the driver installation - This has to be done from the command prompt i.e. without having the desktop started!!!!
If you follow the on screen descriptions from there - then reboot the machine you should be fine - Hope that sounds allright to you
