The expression "boot" is short for, and originates from the word "bootstrap" as in the expression "pull yourself up by your bootstraps".

Historically, a bootstrap program was the first program to run on an otherwise dumb chunk of electronics. Today, booting often includes executing a firmware prom, followed by one or more boot sectors on a disk, before control is passed to initial O/S code which is "run". So bootstrap code lies between the dumb machine and the O/S. We all say that an O/S is "booting" when it's coming up but that isn't strictly true. The O/S is also a program(s) that is "run". We say that an O/S is "running".

There will be other programs (O/S's) that get on their feet via a bootstrap of some kind (eg, an embedded appliance may initially execute a prom before passing control to something else).

Hope that helps.

syncbbdb-bootstrap

syncbbdb-bootstrap(1)					      General Commands Manual					     syncbbdb-bootstrap(1)

NAME

       syncbbdb-bootstrap - synchronize BBDB with Palm device

SYNOPSIS

       syncbbdb-bootstrap [ -port port ] [ -bbdb file ] -ids file -trans file

DESCRIPTION

       This  script  allows  you to synchronize your Palm addressbooks and your BBDB data without using PilotManager(1).  If you use PilotManager,
       this script is unncecessary.

OPTIONS

       -ids file
	      The location of the ids file.  This file is used to track changes in BBDB and Pilot (especially for a full  sync).   If  you  aren't
	      using PilotManager(1) this can be any name but it should always be the same file (eg. ~/.bbdb.ids)

       -trans file
	      The translation file.  This file provides a mapping between the fields in the bbdb records and fields in the pilot records. The for-
	      mat is one entry per line:

	      <pilot name> <bbdb name>

	      It is case sensitive

       -port port
	       Port for pilot (defaults to /dev/pilot, or the environment variable PILOTPORT if set).

       -bbdb filename
	      The location of your bbdb file (defaults to ~/.bbdb).

SEE ALSO

       PilotManager(1).
