How to install and run The Network Simulator - ns-2 - on Ubuntu machine.

Problem description

The ns-2 installation instructions found on ns-2 project wiki are somewhat hardcore and make an impression that Ubuntu is not a good match for the simulator

Installing Windows XP via Remote Installation Services (RIS) or Windows Deployment Services (WDS) system using Realtek

Problem description

You need to install Windows XP (or probably other version) on Realtek Network Interface Card based system (namely RTL8168/RTLRTL8111/RTL8139/RTL8169/RTL8110 and such). You want to use WDS (formerly RIS). Anything you try, you get: "The operating system image you selected does not contain the necessary drivers for your network adapter ..." error.
