How can I change the installation source in Mandrake?

anyway

Hi!

I installed mandrake via cdrom. Now I want to install some additional packages. But when I select those packages in control center it always tell me to insert cdrom.  Currently I don't have cdrom and want to install them from internet. But I don't know how to change the installation resource. Can anyone help me? Thanks alot!

That is because what you want to install is on the cdrom, so you don't have to find them on the internet

btw, you cann't input Chinese?
