[COORDINATION CAPABILITIES WITH THE MACHINE ROM].

There are no coordination capabilities between the option ROM corresponding to
EURO specifications and the machine ROM which does not comply with the EURO
specifications.

When a user is using a new option ROM, an option ROM which matches the machine
ROM currently in use should always be used.
The possible combinations of the installed ROM coordination patterns are as described

below.
