iBook - G4 - Admin access

So I've come across an iBook G4 running OSX 10.4.11 and I'm having trouble gaining administrative access. I don't normally use macs, so I'm new at some of this.

I've been using this guide to help me along - http://www.macshadows.com/kb/index.p...ol_of_Mac_OS_X

Everything works fine until I enter the command - sh /etc/rc .

It runs through the commands and it starts to boot. It boots to a blue mac screen and the cursor appears in the upper left hand corner. Nothing else appears.

So basically, all I want to do is create a user with admin access, and I don't have the correct rights.


Thanks!
