How do I get started with an install?
The default install types all depend on having network access during installation. This install is initiated by either a small boot cdrom or a usb pendrive image. After a few questions the install continues over the network and the installer fetches all the instalation material by using NFS or HTTP.
If you will be installing one of our distributions on a machine that doesn't have a high speed network access then please read the FAQ question about creating a DVD image of the distribution version that you will be installing.
You will need a boot image - please read appropriate FAQ questions on how to download and create appropriate boot media.
Once you have the boot installation media start the computer up from it (e.g. boot from the installation cdrom or from USB pendrive).
You will be prompted for install type - please choose HTTP (NFS is not recommended any more). If on IAS campus again choose HTTP installs but you will have to modify the default location of the install material in order to use the local mirror.
After choosing the install type the installer will initialize your networking and then allow you to modify the preset download location of the distribution. If you will be using the www.elders.princeton.edu download server you can accept the defaults. If you will be using IAS mirror you should modify the default server and location as follows:
Where #DistVersion? may be 2WS, 2, 1WS, 1 and #Arch might be i386 or x86_64
