Typing 'dmesg' should provide you with most of that information.

where's the dmesg.conf, i don't know if that is the file for error configuration but something like that will show the locations of the messages.

Thanks again.

use the command dmesg (diagnostic messages) as a superuser.

Alternately, since that only gives you information regarding pre runlevel messages, also check /var/log/messages for information.
