<pre> |
| |
mkdir -p suse101/CD1 |

| Select "Change Source of Installation". The media you used to install SLES10 will be listed as an installation source. You may also wish to create a local repository by copying the contents of the RPM directories on the five CDs to a local directory to avoid the need to flip CDs during LON-CAPA installation. Information about building a local repository is available at:<a href="http://portal.suse.com/sdb/en/2004/02/yast_instsrc.html">http://portal.suse.com/sdb/en/2004/02/yast_instsrc.html</a>. |
Select "Installation Source" and change to either point at an internet installation repository close to your location (see <a href="http://en.opensuse.org/Mirrors_Released_Version">http://en.opensuse.org/Mirrors_Released_Version</a>), or a local institutional source you have built from the SuSE 10.1 CDs, or if using a DVD you may prefer to continue to point at the installation DVD. |
