OpenBoot Firmware was pioneered by Sun Microsystems as a solution to
the problem of devices (e.g. PCI cards, Sbus cards) going to into
systems with totally different CPUs (e.g. mc68020, SPARC, PowerPC)
and reconciling that with writing only one driver for the PROMs on
the cards. The scheme is that you write the driver in an interpreted
language, and the CPU motherboard has local interpreter
implementation, specific to the CPU. Voila!
This was standardized as IEEE 1275.
Now the evil part: the interpreted language?
Forth.
good goal, bad plan,
