Overview; Power-Up The System - Motorola MVME2700 Series Installation And Use Manual

Overview

This chapter supplies information for use of the MVME2700 series of
single-board computers in a system configuration. Here you will find the
power-up procedure and descriptions of the switches and LEDs, memory
maps, and software initialization.

Power-up the System

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. The MPU,
hardware, and firmware initialization process is performed by the PPCBug
firmware at power-up or system reset. The firmware initializes the devices
on the MVME2700 module in preparation for booting the operating
system.
The firmware is shipped from the factory with an appropriate set of
defaults. In most cases there is no need to modify the firmware
configuration before you boot the operating system.
