Can... can you rephrase that in a coherent manner?

Well the BIOS stands for Basic Input/Output System, it just checks over the hardware quickly to make sure the computer is functional before the OS loads, this is called POST (Power on self test).

Within the BIOS you get "basic" (as the name suggests) controls such as boot order, drive mode (ahci, raid, ide), and the time. You can also have more advanced features such as CPU core control for overclocking. The BIOS is stored on ROM (Read Only Memory) and can be found on the motherboard as a small chip.

On modern motherboards we use what is called UEFI, which is Unified Extensible Firmware Interface. It takes a lot of the 'features' of a BIOS but when hardware data is collected on POST it passes it to the (UEFI based) OS. Just better boot times and stuff. UEFIs generally also feature a graphical interface with mouse pointer control.

Hope that helps.

If you are asking what BIOS updates are for.... When manufacturers release new mobos on new chipsets BIOS is buggy like any other software. Updates fix bugs, add comp ability and even features.
