[CentOS] Question on installing .run file

I am trying to automate the install of the ati driver package.
Basically all I do is hit return about 6 times and take all the defaults.

I tried to do this in a file that I then made executable with 744:

sh ati-driver-installer-10-8-x86.x86_64.run << EOF









EOF



but then it starts like its doing something but never does anything.

How might I automate such an install script. Again all I do is hit 
return 6 times
and accept all the defaults.

Thanks,

Jerry
