device options, such as memory configuration, drive types, monitor, network address, etc. 
The data are stored in a configuration file and enable the operating system to load the correct 
device drivers and configure the correct device parameters. . If changes are made to the 
hardware configuration, the user can change entries in the configuration file using the SETUP 
program. .
