Yes,

When you get to the boot menu, hit tab and add the following to the
kernel command line:

rootpw=<hashed password>

To generate the hashed password, use 

openssl passwd

When I got to the engine / web administrator, my Host was not detected and I couldn't change it's IP, only the hostname... On the TUI I can't change the IP because I'm registered but can't change it also on the engine. Is this correct?
