Hi, every body
Thanks for your effort to release new installer

however, the new rc3, coudn't install the sarge I downloaded 3 months 
ago ( Dec, 2004).
have to download all the 14 CD. ( I use a local server to install in all 
my machine
of the lab).
does rc3 install only the newer release , which one ??
