Where are the boot messages?

[Jaromba]

Where are the boot messages?
I booted Knoppix 5.1.1 DVD with the boot code "knoppix testdvd" but the next time I looked KDE had launched and the boot messages had disappeared.
Where are these messages stored?
On Mandrake it used to be /var/log/messages ... but I can't find them on Knoppix.
Any help will be valued and appreciated.

$ sudo dmesg

should do...
