Once upon a time, Sun Sparcstations stored the password in the NVRAM chip. This chip had an internal battery. If you lost the password, that was it, the only official fix was to replace the NVRAM chip. (At least it was socketed.) Even that turned out to not be a serious problem, though; it turned out if you removed the chip entirely, the system would boot to the ROM monitor. Then you could put the chip back in "hot" and clear the password. There is no such thing as security from someone who has physical access to the hardware.
