BIOS stands for Basic Input Output System. It is a collection of software utilities included with the motherboard of most computers, and used to boot the system as well as perform a number of hardware related tasks.
Bios are short pieces of text which give a brief curriculum vitae of a person, often an author. Often found on the inside margins of book covers. Short for "biographies". of course the "software" is actually firmware.
Oh aye. Sorry.
