Stepping boot-up
 
I want to use my boot up messages to help optimize my kernel... and I know there is a large portion of the boot-up that isn't recorded in the /var/log/syslog (or boot.log). Is there a way to make the boot-up step, that way I can write what's written to the screen down?

From the prompt, type: dmesg | less

Try this in a terminal: dmesg | less
This will print the boot message one page at a time, use down arrow key to proceed one line at a time or space bar to proceed one page at a time. Hope this helps.
oops, slow typer here:D

what I'm saying is that the information I need is not in there. During the beginning of my boot process there is a long list of devices (including ns87 and generic (as I said I can't catch them all) and it says something to the effect of device not found removing. So I wanted to remove support for all of those from the kernel

So you tried dmesg and it did not have the information that you saw go by on boot up?

It only has some of it... I did some googling and from what I read, there is some portion of the boot that can't be logged...

So to answer the question I did see part of what is displayed on the screen when I use dmesg, but not all of it.
