UNIX for Dummies Questions & Answers

Hi. I have a few "newbie" questions. This is a 2 part question which I was unable to find an answer. First, I have recently installed the kernel patch and video driver from Nvidia for my GeForce Ti 4800 video card for 3d on a fresh install of Redhat 8.0. I need to do all of the updates for Redhat. My question is, when I do the updates for the new kernels, will the kernel and video updates still be there, or will I have to reinstall them? Secondly, when I get an update for a new kernel, when I reboot, Grub lists the old and new kernels to boot from. Do I still need the old kernels, or can I delete them? Thanks.

First, if its a standard kernel patch driver for the Nvidia, you may have to recompile each new kernel, depending. I've had vid drivers that crossover, and vid drivers that need to be compiled into the kernel each time.

Secondly, leave the old kernels in grub until you have booted intot he new kernel once or twice to make sure it doesnt conflict in any way with your system. Until you test a new kernel its good to keep the old kernel on the bootlist as a backup, in case something should go wrong.
