I/O Address Map<br />
The table below indicates the I/O regions that are used by the onboard hardware of the <strong>CME136686LX</strong>. This<br />
tables represents a default (or near default) cpuModule configuration. Any I/O addresses not listed can be<br />
considered available for use by peripheral boards.<br />
WARNING Installing a peripheral that conflicts with any of the addresses listed below will prevent<br />
the system from functioning!<br />
Depending on your cpuModule configuration, the list of used I/O addresses may change slightly. In particular,<br />
devices indicated by an asterisk (*) are user-configurable, and may be enabled/disabled/modified from the BIOS<br />
setup.<br />
