Using the OSDT to Customize OSIs
The OSDT includes predefined OSIs (operating system implementations) for a number of operating systems. If you are using one of these systems, you do not need to perform any customization.
If, however, customization is required, it is recommended that you select the OSI that is closest to the system you will be using and use this as the base to which you add the required customizations.
To use an existing OSI as a template, select the desired OSI from the OS Implementation drop-down list. Then, select File > Save As from the OSDT menu, and provide the name that you would like to use for the new OSI you are creating.
After making any changes to individual OSI settings on the various tabs, select File > Save from the OSDT menu to save the changes to your OSI. If you try to close the OSDT before changes have been saved, you will be asked if you want to save the changes.
Rational Statemate will not allow you to save changes to the predefined OSIs. If you make any changes to these OSIs, you will be asked to save the modified profile under a different name.
