There are two different netinst CD images which can be used to install squeeze with thedebian-installer
. These images are intended to boot from CD and install additional packages over a network, hence the name 'netinst'.The
difference between the two images is that on the full netinst image the base packages are included, whereas you have to download these from the web if you are using the business card image. If you'd rather, you can get a full size CD image which will not need
the network to install. You only need the first CD of the set.
