Being a neophyte here, I need some grounding on NVRAM. What is it? Where is it? How is it created? How is it changed? How is it cleared? Thanks--tpmco |

Is NVRAM located on the motherboard? |

NVRAM is part of the PRAM i believe. |

Thank you, OSX Guru. I have read elsewhere that PRAM was a component of NVRAM, but that NVRAM was an encompassing set of values and was uncertain if a PRAM clear (zap) would clear the entire NVRAM. tpmco |

It's short for "non-volatile RAM". Basically, it is a small amount of memory that survives when you shut down the computer. Mac OS 9 and Mac OS X use it to store a variety of settings. The most important settings are those which control the boot process (logically speaking, those settings can't be stored on disk, since which disk to boot from is one of the settings you need to store). It can be changed by various programs and control panels--the startup disk control panel, for instance. It can be cleared by zapping the parameter RAM, or by pressing the motherboard reset switch, or by removing the motherboard battery for long enough, and probably a few other methods I'm not thinking about at the moment. |
