Zapping the PRAM

Send Article to a Friend

With the exception of date and time, all system-wide preferences are reset to default values by zapping the Parameter RAM (PRAM). If you wish to zap the PRAM, hold down shift-command-option and choose the Control Panel in System 6. In System 7 hold down command-option-p-r (Be sure Caps Lock is off!) at boot time, and then let go at the second startup chime. The Macintosh will restart shortly after displaying the "Welcome to Macintosh" screen, which indicates that PRAM has been reset. The date and time settings are actually read out of PRAM before it is zapped, then written back in afterwards. Note that if a Macintosh's battery is drained, the date and time will reset to the default value (12:00 am, January 1, 1904) after each startup.

What's in the PRAM? -- If you have ever wondered what information is stored in the parameter RAM, this list should answer your questions and help you in figuring out when zapping the PRAM might be useful.
