firmware: /ferm'weir/ n. Embedded software contained in EPROM
or flash memory. It isn't quite hardware, but at least doesn't have
to be loaded from a disk like regular software. Hacker usage differs
from straight techspeak in that hackers don't normally apply it to
stuff that you can't possibly get at, such as the program that runs
a pocket calculator. Instead, it implies that the firmware could be
changed, even if doing so would mean opening a box and plugging in a
new chip. A computer's BIOS is the classic example, although
nowadays there is firmware in disk controllers, modems, video cards
and even CD-ROM drives.
