Would like to get back my command prompt!

[Michael Neeff]

A newbie with installing FreeBSD 5.3...I installed X and got excited to 
direcly log on to X (xdm) with the dialog box. I modified the lineto turn 
xterm on:
ttyv8 "/usr/X11R6/bin/xdm - nodaemon" xterm ON secure.
Now I am stuck in a login loop... I would like to configure X and install 
KDE, but it is stuck on the ChooseSessionListWidet I can only choose 2 
options DEFAULT/FAIL SAFE and CANCEL and nothing happens in either case... 
hitting CTRL+ALT_+BKSPACE does nothing

How do I just login to the command prompt without X opening directly?? I 
think I tried option 6 and it gives me a command prompt but I cannot edit 
any file.

Thanks in advance.
Mike
