A.1. Booting the installer

For more information on where to get CDs, see Section 4.1, “Official Ubuntu CD-ROMs”.

Some installation methods require other images than CD images. Section 4.2.1, “Where to Find Installation Images” explains how to find images on Ubuntu mirrors.

The easiest way is probably to download the (CDROM) image, because the files most people need are there on the image.

The subsections below will give the details about which image(s) you should get for each possible means of installation.

A.1.1. Booting from CDROM

First of all download the image for your architecture and burn it to a CD/DVD.

A.1.2. Booting from network

It's also possible to boot the Ubuntu installer completely from the net. The various methods to netboot depend on your architecture and netboot setup. The files in netboot/ can be used to netboot the Ubuntu installer.

A.1.3. Booting from CMS disk (z/VM)

It's recommended to download parmfile.ubuntu and ubuntu.exec as well, but using ascii mode.

Properly transfered to CMS, the installation files can be booted by just executing the ubuntu.exec REXX script. Alternatively you can also execute the steps from the script manually.

/* REXX EXEC TO IPL Ubuntu for        */
/* z Systems FROM THE VM READER.      */
/*                                    */
