Figure 18.1: Rom Devices In Openarchitect - HP bh5700 User Manual

Offset 7f000
The boot ROM is located on device 0 and contains the OpenArchitect zmon application that
operates as a boot loader and includes a device bootstring. Device1 contains the application
flash1 image of the Linux operating system and the OpenArchitect overlay file system.
Application flash1 is the primary working image for the switch. Device 2 contains the
application flash 2 that is an exact copy of application flash 1. You would only boot from this
device if application flash1 is corrupted and you need to restore the switch to the factory-
shipped configuration.
