A computer BIOS initializes and tests the CPU, RAM, chipset, video card, keyboard, hard drive, optical disk drive, floppy drive, and interrupt handlers. Additionally, the bios will check ports on a computer.
To manage simple devices (system BIOS)To start the computer (startup BIOS)To change settings on the motherboard (CMOS setup).
Because BIOS had to do with the booting of a computer.

The BIOS is used to manage simple devices (system BIOS), the BIOS is used to start the computer (startup BIOS), and the BIOS is used to change settings on the motherboard (CMOS setup).
No, the BIOS wizard is to change settings on the motherboard and how devices are used. The setup wizard for a operating system is just started in the BIOS.
BIOS and drivers use RAM (random access memory) however, in different forms. The BIOS is essentially a small chip of RAM that houses the code for running the operating system and the hardware. This hardware is controlled by the device drivers which run on the operating system which uses separate RAM which has a far greater capacity than the BIOS. this RAM is also shared by the operating system and is usually found in sticks that plug into the motherboard. the BIOS can operate without RAM but not the other way around
The portion of the BIOS that manages essential devices before the operating system is launched is called the Power-On Self-Test (POST). During POST, the BIOS checks hardware components such as the CPU, RAM, and storage devices to ensure they are functioning properly. If any issues are detected, the BIOS will provide error codes or beeps to indicate the problem. Once the checks are complete, the BIOS initializes the boot sequence to load the operating system.
No, you do not need to adjust the BIOS when installing an operating system. However, you can set the BIOS to determine the order in which attached devices will boot. That capability allows you an option (one of several options) to install different operating systems on different devices and choose which operating system boots when you start the computer.
