The ChorusOS 4.0 Installation Guide explains how to download and install Sun Embedded Workshop.
When the installation is complete, you have all the binary components required to build an instance of the ChorusOS operating system. To create a system image, follow the instructions in the appropriate ChorusOS 4.0 Target Family Documentation Collection.
A boot server is a system that provides an instance of the ChorusOS operating system for downloading to target systems. A boot server is useful if you download the same image to many targets. To install an instance of the ChorusOS operating system on a boot server, follow the instructions in the ChorusOS 4.0 Installation Guide. Note that the system where you installed the development environment can be used as a boot server.
When you have created the instance of the ChorusOS operating system you require, and built a system image, you need to install it on the target system. There are several ways to do this, including:
Download the image at boot time from a boot server
Load the image from media located on the target system
