# Setup Type

On this dialog box you can select a setup type.

There are different setup types:

- Master Application Server (MAS)
    This server contains these components:
    - The runtime data dictionary.
    - The porting set.
    - The database driver.
    - The audit server.
    - The print manager.
- Application Server (AS)

    This server only contains a porting set to connect to the application server. During the installation of an AS the Application dialog box displays to select the correct Infor LN or Baan version.

- DB-Connection
    This server contains a porting set to connect to the RDBMS server.

For an AS or DB-Connection you must select the installable unit Infor ES Porting set. If you select more, a warning message is displayed. If you want to setup a Enterprise Cluster, you must first install the MAS and install the AS or DB-Connection later.

The Package dialog box only displays during a new installation.
