Power-On

The JavaStation programmable read-only memory (PROM) includes TFTP client and DHCP client implementations and is thus able to carry out the boot sequence. At power-on, the PROM checks to see if flash memory is present. If so, it then checks to make sure the JavaOS in flash is not corrupted. If the JavaOS in flash is valid, then the PROM loads it into memory and transfers control to it. JavaOS initializes itself and then completes Task 1, described below.

If any of the above tests fail, JavaOS is not loaded into memory and the PROM proceeds to complete Task 1 itself.
