Getting Messages Before Dmesg
 

I'm currently on a linux machine and want to explain to a class of mine the boot process in depth. I understand it quite well, but wanted to show them how things are handled as the system boots (I'm using Red Hat). So for example, I wanted to show them all the messages that appear when the system boots, not just the contents of dmesg. I want to show them lines such as:
and then the rc.sysinit part:
However, since these are not displayed is dmesg and they go off the screen, I'm not sure how I can get some type of file with all the content that is displayed to the screen. Any ideas? Thanks for your time.

Hi LinuxGeek.

Look in /var/log/messages. (You have to be root to view it, I think.)

Good luck!

Thanks but this isn't quite what I'm looking for. I'm looking for something to get me everything that was outputted to the screen before I was given the log in prompt. So it would include things such as
I
INIT: Entering runlevel: 3
and
Starting xfs: [ OK ]
