The loading of operating system code from a disk
code from a disk or other storage device into a
computer¡¦s memory. Bootstrapping is so-called
because it typically occurs in steps, starting with
a very simple program to read a sequence of blocks
from a fixed location on a pre-determined disk into
a fixed memory location. The data thus read is the
code for the next stage of bootstrapping, it typically
causes an operating system to be read into memory,
which then begins to execute.
