Dmesg isn't a log file as such. It's a dynamic snapshot of kernel-related
messages that are kept in a limited-memory buffer. For that reason, the
oldest entries eventually disappear.
Just type 'dmesg' at a prompt to see it.
Many distros (at least intelligent ones) will save the initial dmesg info
to a file in /var/log in order to keep the bootup messages for later
You can also do this manually at a prompt:
dmesg > /path/to/some/filename
which redirects the usual console output to a named file.
