boot
booting
To load and initialise the
operating system on a computer. Normally abbreviated to
"boot". From the curious expression "to pull oneself up by
one's bootstraps", one of the legendary feats of Baron von
Munchhausen. The bootstrap loader is the program that runs
on the computer before any (normal) program can run. Derived
terms include reboot, cold boot, warm boot, soft boot
and hard boot.
The term also applies to the use of a compiler to compile
itself. The usual process is to write an interpreter for a
language, L, in some other existing language. The compiler is
then written in L and the interpreter is used to run it. This
produces an executable for compiling programs in L from the
source of the compiler in L. This technique is often used to
verify the correctness of a compiler. It was first used in
the LISP community.

bootstrap loader
(foldoc) | bootstrap loader
A short program loaded from {non-volatile
storage} and used to bootstrap a computer.
On early computers great efforts were expended on making the
bootstrap loader short, in order to make it easy to toggle
in via the front panel switches. It was just clever enough
to read in a slightly more complex program (usually from
punched cards or paper tape), to which it handed control.
This program in turn read the application or {operating
system} from a magnetic tape drive or disk drive. Thus,
in successive steps, the computer "pulled itself up by its
bootstraps" to a useful operating state.
Nowadays the bootstrap loader is usually found in ROM or
EPROM, and reads the first stage in from a fixed location on
the disk, called the "boot block". When this program
gains control, it is powerful enough to load the actual OS
and hand control over to it. A diskless workstation can use
bootp to load its OS from the network.
