Thank you Akemi, I had no idea that I could do this.
For my video drivers I need kernel 3.4 or later. It seems from these sites that 3.0 and 3.8 is available - has anyone on the list had experience with this? How stable is SL 6.3 with kernel 3.8?

Thanks again, Bill

I am forced to look for a Linux distro with a newer kernel - I am using Xubuntu at the moment which does not make the fan noisy but is unstable compared with SL - one or two crash reports per week etc. I might try Fedora with MATE next week.

If you wish to run SL with a newer kernel, look into ELRepo's
kernel-ml (mainline kernel) [1] or kernel-lt (long-term kernel) [2].
Both kernels are from kernel.org.
