The BIOS environment in a computer (PCs only, not Macs) is a set of screens accessible only during the first part of the booting process. One usually presses a key, such as delete or f2 to get to the BIOS screen. The BIOS screens allow the user to change settings about the hardware of a computer. These settings are usually stuff like boot order, peripheral settings, hardware clock, etc. Be careful when changing settings in the BIOS, as changing the wrong setting may permanently damage your computer. Unless you know what you're doing, leave the BIOS settings alone.
List settings commonly configurable through the BIOS setup utility.
Power-on self-test (POST): Checks hardware components during startup. Basic Input/Output System (BIOS) settings: Allows users to configure system settings like boot order and time/date. BIOS updates: Enable users to update the BIOS firmware for improved system compatibility and functionality.
The Mac does not have a BIOS and so the settings cannot be checked.
You'll loose your BIOS settings and the computer won't be able to recognize some of the settings. If the battery goes dead, replace the battery, enter the BIOS settings and load the default, then do whatever is necessary under YOUR BIOS to recognize your hardware, then save the settings.
No, removing the bios battery on a laptop will not reset bios settings.
Two examples are resetting the BIOS to the default settings and swapping between two different BIOS chips for boards with multiple BIOS.

The BIOS (Basic Input/Output System) is the built-in system of your motherboard. It allows the user to change motherboard settings and other various settings.
The CMOS contains user-defined settings for the BIOS. The Bios is a program that contains hardware instructions on how to start the computer.
