Thanks a TON! I got it to go through
I had problems switching "init 3". Once I did this the system would hang up while trying to switch the drive/local disk to "read/write mode". I rebooted several times to no avail. Here are the steps I took to get it working:
-I booted to the CentOS installation cd, used F5 to get into the "Linux-Rescue" mode (!! Outstanding Tool btw !!) and switch to "init 5".
-I then rebooted to GNOME as a normal user.
-I opened a terminal window and typed "su root", then the password.
-I then typed "cp /etc/X11/xorg.conf /etc/X11/xorg.conf_old
-Then "gedit /etc/X11/xorg.conf". I commented "dri", replaced "nv" with "nvidia" and saved it as "xorg.conf"
-System failed to load X Windows system because I changed the "xorg.conf" and loaded the prompt.
-typed "/usr/sbin/setenforce 0"
-typed "yum install kernel-devel" (worked great!)
-typed "sh /home/user_name/Desktop/NVIDIA-**.run"
-installation failed again because "Plug and Play OS" was set to Yes instead of No in my BIOS (who would of guessed)
-rebooted, fixed BIOS, rebooted again
-repeated Setenforce, Yum, SH and everything Installed Great.
-after the installation the installer dumped me back at the command prompt. I then remembered to type "/usr/sbin/setenforce 1" and "reboot"
Once the machine rebooted for the final time everything worked out Great! I don't know what was going on with "init" but that just seemed to hang up every time I swiched it.
So it all came down to BIOS settings. I took the above steps only because it's all I could think of, and because of your (liquidtenmilion) help. I hope this helps someone else out in the future.
