boot block
<operating system> A program at some fixed location on a hard disk,
floppy disk or other media, which is loaded when the computer is turned on or
rebooted and which controls the next phase of loading the actual operating
system. The loading and execution of the boot block is usually controlled by
firmware in ROM or PROM.
