If you already have a previous version of the CD you are
downloading, jigdo can re-use files on the old CD that are also
present in the new image, and you do not need to download them
again. Mount the old CD ROM and enter the path it is mounted under
(e.g. `/mnt/cdrom').
Alternatively, just press enter if you want to start downloading
the remaining files.

The jigdo file refers to files stored on Debian mirrors. Please
choose a Debian mirror as follows: Either enter a complete URL
pointing to a mirror (in the form
`ftp://ftp.debian.org/debian/'), or enter any regular expression
for searching through the list of mirrors: Try a two-letter
country code such as `de', or a country name like `United
States', or a server name like `sunsite'.

specify a different mirror here. If this is the mirror you want to use, press

simply copy the URL you entered above; this does not work because
the path on the servers differs!

The fact that you got this far is a strong indication that `sarge-i386-3.raw'

which you can interrupt safely with Ctrl-C if you do not want to wait.
OK: Checksums match, image is good!
