To use the tutorial,you need to have Suse Linux 10.0, VMware Workstation, VMware Player and Windows XP Installation CD. General steps are you use Suse Linux 10.00 as your host, and install VMware Workstation and VMware Player to create a virtual machine that will allow you to install Windows XP, thus enabling you to have both Suse Linux and Windows XP at the same hardware.
