Problem re Installing Debian with Sarge

[Stephen Liu <satimis@yahoo.com>]

Hi folks,

I ran sarge-i386-netinst to install Debian.  Because
only dynamic IP allocated on broadband connection, I
left the IP address empty resulting in uable to
connect broadband finally.  Now I have the base Debian
installed but starting 'init 2' only.

Now I got broadband connected by editing both
/etc/ppp/peers/dsl-provider and /etc/ppp/pap-secret. 
Ping yahoo.com, debian.org, etc were found working.

Kindly advise how to proceed further to complete the
installation of Debian.

TIA.

PS. In my case.  During installation how to overcome
the problem of leaving 'IP address' empty.  

Broadband connection - via router
login and password required.

Tks

B.R.
