Operation

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 2-1shows the basic initialization process that takes place during MVME5100 system start-ups.
