Viewing bootup messages


Hmm, this may seem like a silly question, but I was wondering how to view the complete messages at boot time. (No, I dont mean /var/log/messages either).
There are messages at boot time I can't seem to view no matter what I do. If I SHIFT(PGUP), I can scroll up, but this doesn't work for long as the buffer gets deleted after the TTY font get loaded. So, I have tried to use the vga=ask option in lilo, but I get the same effect as using Frame Buffer (vga = xxx). Anyway, it seems like I am missing something as far as a log goes maybe (did I?) Please help. /var/log/messages isn't adequate (some of the messages I have noticed , before they went away, aren't in /log/msgs) .
If there isn't a log file created, is there some way to use a redirecter ( > ) at boot time to send these mesgs some where?
At any rate I hope someone can help!


Sincerely,

Brady

You mean this one?:

DMESG(8) DMESG(8)


NAME
dmesg - print or control the kernel ring buffer

SYNOPSIS
dmesg [ -c ] [ -n level ] [ -s bufsize ]

DESCRIPTION
dmesg is used to examine or control the kernel ring
buffer.

Upon boot, the dmesg output is from the kernel booting, showing the devices it has found and if it has been able to configure them at all (aside from userland configuration). This log is also available in the file /var/log/dmesg.

dmesg | less will let you see them a page at a time.

Yes, dmesg is the command I was looking for. The only thing is, I don't know where it is getting the input from, since I don't have the file /var/log/dmesg -- but at any rate it works, and that helps a lot!
Thanks much

A handy command could be also
dmesg > mylog (or wathever you like)
This saves a text file easy to read.
Ciao
