IPL

IPL is an acronym (pronounced "eye-pee-ell") for Initial Program Load, and is the process where the hardware initiates the loading of the base operating system.

IPL can be used

• as a verb ("IPL the system")
  • with past tense ("then we IPLed")
  • and present tense ("while we were IPLing")
• as a noun ("after the next IPL.")

On other systems, this is called the "Bootup" or "Bootstrap" process.
