Initial Conditions
After you have verified that all necessary hardware preparation has been
done, that all connections have been made correctly, and that the
installation is complete, you can power up the system. Applying power to
the system (as well as resetting it) triggers an initialization of the
MVME162P4’s MPU, hardware, and firmware along with the rest of the
system.
The Flash-resident firmware initializes the devices on the MVME162P4
board in preparation for booting the operating system. The firmware is
shipped from the factory with a set of defaults appropriate to the board. In
most cases there is no need to modify the firmware configuration before
you boot the operating system. For specifics in this regard, refer to Chapter
3 and to the user documentation for the MVME162Bug firmware.
