To see other, non-default possibilities, use the BIOS Setup utility (see page 3-23), which lists port and audio device configurations in the System Devices menu. The tables in this section show typical resource usage as set up by the OmniBook BIOS. Plug-and- play operating systems, drivers, and BIOS Setup settings may change some of the entries. Table 1-7.
