Is there a way to get it to go into console mode without rebooting?
What do you want to do exactly?
To "get it to go into console mode", use one of the above, or logout (exit) and login with admin.
If you want to change the configuration, resetting the "auto" (go to the server console) or "login" (boot to a login prompt) option, go to the console as stated earlier, and configure your server.
That would require a reboot if I remember correctly.
It really only matters when you're going to reboot so that's easy enough.
Offcourse there is probably some way off doing this without rebooting and going through all of the configuration. I just don't know how...
I do believe this is about the same for 6.0 and 6.5.
