Is it possible to perform an FC 3 install without a CD ?

[Fabrice Beauvir]

Works fine paul !
  It was so hard to find 5 floppy because I 'd stopped using such a 
media for  3 years but  I  succeed .

Now  FC 3 is  quite installed.

Just a little problem.. When you execute system-install-package, it 
looking for CDs !!!
AND when you set tree to the http dir it is unable to load .discinfo.
("system-install-package -tree=http://myhttp/mydir" )

I was obliged to copy my 3 install CD on the HDD and I wonder why 
system-install-packages don't use the same sources as yum.....

thank you for your help.
