OBP explained.

Hi Gurus,

Correct me if I am wrong. Booting an OS means loading it in memory . What is OBP in solaris. If we are typing some commands at ok> where are we actually do that.
What is the difference between frimware and OBP.

I know I am asking silly things but I need answers. SmilieSmilie

Thanks in Advance.

OBP was a new approach to the BIOS(used to load your system from storage to memory, configure hardware and etc) the idea was that we have more need for firmware/drivers integration on lower level(BIOS) and other options not provided by the standard BIOSes(such as cross-platform firmware able be load in any system, boot-time diagnostics).
OBP is dead as not used in any production systems, the next thing with this idea is EFI by Intel.

firmware is small program used to control some hardware, OBP is small program used to control some hardware, load other small programs and check the hardware Smilie

Untrue. Used on probably tens of thousands of production systems.
