It controls the system operation before the kernel becomes available. It provides a user interface and firmware utility commands known as FORTH command set. These commands include the boot commands, the diagnostic commands & the commands for modifying the default configuration. Command to determine the version of the Open Boot PROM on the system: # /usr/platform/'uname -m'/sbin/prtdiag -v (output omitted) System PROM revisions: ---------------------- OBP 4.16.4 2004/12/18 05:21 Sun Blade 1500 (Silver) OBDIAG 4.16.4.2004/12/18 05:21 # prtconf -v OBP 4.16.4 2004/12/18 05:21 Open Boot Architectures Standards: It is based on IEEE standard #1275, accord...
