System Resources

Below are default values for system resources. To see other, non-default possibilities, use the
System Configuration Utility (SCU) which lists port and audio device configurations in the
Input/Output menu. For additional information on configuring system resources, refer to the
System Configuration Utility section on page 48.
The tables in this section show typical resource usage as set up by the OmniBook BIOS. Plug-
and-play operating systems, drivers, and SCU settings may change some of the entries.
