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
MVME177P
’s MPU, hardware, and firmware along with the rest of the
system.
The EPROM- or Flash-resident firmware initializes the devices on the
MVME177P
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
MVME177Bug firmware.
