Please Help! (unexpected prompt after Panther install)

[MIDI_EVIL]

We restarted our iMac after installing a new HD and installing OS X panther,

Now we are prompted with a black screen and the writing:

Darwin/BSD (Localhost) (Console)
Login: IP packet filtering initialized, divert enabled. rule-based forwarding enabled, default to acccept, logging disabled
IPv6 packet filtering initialized, default to accept, logging disabled
IP firewall loaded



??? please if anyone knows what to do, we have to type something ?

It's now just a black screen,
