System Powerup
After you have verified that all necessary hardware preparation is done, that all connections
were made correctly and that the installation is complete, you can power up the system.
Initialization Process
The MPU, hardware and firmware initialization process is performed by the PPCBug firmware
upon system powerup or system reset. The firmware initializes the devices on the MVME5100
in preparation for booting an operating system.
The firmware is shipped from the factory with an appropriate set of defaults. Depending on your
system and specific application, there may or may not be a need to modify the firmware
configuration before you boot the operating system. If it is necessary, refer to
Chapter 3,
PPCBug Firmware
for additional information on modifying firmware default parameters.
The following flowchart in
Figure 2-1
shows the basic initialization process that takes place
during MVME5100 system start-ups.
