Xorux 1.25 forget root password

Hi,

We want to go into root, however we have forget the password. We tried many password, even the default xorux4you.
We still can't find the right combination.

Is there a way to reset it?

I tried to follow the https://www.liberiangeek.net/2014/09/reset-forgotten-root-password-centos-7-servers/
to reset. However after Ctrl+x, it boot into xorux, There is no way for me to the prompt.

Any ideas?
