Chapter 6. Map construction overview
Creating a fully functional map involves four fundamental steps:
• Creating a map entry in the module repository
• Populating the tree structure with modules
• Preparing source files for modules
• Specifying the module-installation order
This chapter focuses on the concepts behind creating a map tree structure and defining certain settings that
affect map behavior. For step-by-step instructions on creating a map entry, defining settings for a map, or
any other process described in this chapter, refer to the ImageUltra Builder help system.
Creating a base-map tree structure
The New Map Wizard enables you to create a new base map from scratch or to create a new base map
using an existing base map as a template. The New Map Wizard creates the new map entry in the repository,
assigns the map a file name, and places the map in the correct location of the repository. To access the New
Map Wizard for base maps, click Insert in the Main window menu bar, and then click Base Map.
If you create a new map based on an existing map, you simply make the necessary changes to the tree
structure and attributes. If you create a new map from scratch, you are responsible for:
• Inserting all menu items
• Inserting all modules
• Defining all menu-item attributes
Inserting menu items in a base map
Menu items are responsible for the menu choices displayed at the target computer during the installation
process. Menu items also determine the hierarchy within the base map, meaning that some menu items are
subordinate to other menu items. Each menu item listed in a base map directly corresponds to a choice
made at the target computer during the installation process. When a menu item is chosen during the
installation process, that action directs the installation program to accumulate modules associated with
that menu item or to display a new menu of subordinate menu items. In some cases, both actions occur
simultaneously. When the person performing the installation makes the final selection from the final menu,
the installation program installs all of the accumulated modules. The accumulation of menu choices during
the installation process transforms the Smart Image into a customized image for a specific target computer.
As you develop your tree structure, you might want to think of the menu items as an outline for the installation
process associated with the entire Smart Image.
Assume that you want to construct a base map that gives the installer a choice of installing Windows XP
Professional or Windows 2000. The following illustration shows a base-map tree structure with two menu
items (Windows XP Professional and Windows 2000) before modules or submenu items are added. Also
shown is the corresponding default installation screen as it would appear at the target computer.
