did you get past the "Do you already own a mac" screen?

yes because i typed this
-x "Graphics Mode"="640x480x32"
with the " " " ", exactly like they are and it skipped the "do you already own a mac bit..." and made the admin user.

Issue: Upon install, the process hangs in an infinite (?) loop circling between chosing language and creating / transferring an user acount ("Do you already own a mac?").
According to the forum, the problem seems to be connected to problems concerning the network card.

Solution 1: Importing an account from an existing (Tiger) installation.

Solution 2: Booting with the flag "Graphics Mode"="640x480x32". The resulting low screen-resolution prevents the setup screen, thus skipping the "loop". As one is not able to create a new username, only the default "admin" is created. This can be changed later on.

Solution 3: Some people reported success with disabling the network card in the bios or disconnecting the cable.

hope that helps
