adding new packages

[Albert DE WINT]

Hi,

I installed Fedora Core 1 from ISO's previously downloaded on my
Mandrake partition.  I did not actually burn the disks. (It's a waste of
CDROM's)

Now I would like to add some packages.  (I may need some tools and
libraries to compile an OSS sound module and to have the
nVidia-installer compile a 3D driver.)

After selecting the packages, the Fedora installer requests to insert
the 1st CDROM, which obviously I don't have.  

Is there a way to install the selected packages from the ISO's,
previously stored on my Mandrake partition?  Or will I have to burn the
disks anyway?

Thanks for any assistance.

Albert
