Blakethe BIOS is firmware which contains information for hardware, operating systems and drivers to interface with the motherboard components. It stores information concerning what hardware is available.
The POST is the Power On Self Test which the BIOS runs when you power on the computer. It tests the various components to ensure correct function before passing program control to the boot system on the device selected as the boot device in the BIOS settings.
- Basic Input/Output System (BIOS) is a collection of basic low level I/O driver routines and bootstrap routines used to perform initial startup of the computer, load the OS loader from hard disk, and pass control to the OS loader (which will load and start the OS).
- Power On Self Test (POST) is one of the first routines in the BIOS that runs. It performs a series of hardware functionality tests and if a problem is found flashes error code patterns on LEDs (or in some systems may draw a very simple error symbol on the display) for diagnostic purposes, if all of the POST tests pass, control is returned to the BIOS which finishes initial startup of the computer, etc.
Bios are the computers power is initially turned on.

How does the startup BIOS communicate errors during POST if video is not yet available?
The BIOS communicates erros druing POST By giving a beep code.
Can you change from BIOS to UEFI and if so how?
The difference between BIOS and UEFI is built into the motherboard chipset; you cannot change an existing motherboard from BIOS to UEFI, all you can do is replace the entire motherboard (and probably the CPU and the RAM as well) with an UEFI based motherboard. (Deleted the previous answer in its entirety because it was compl Save etely incorrect)
Where to find the rpm?
If you are talking about computer fans, then BIOS should have it. To get to BIOS, you must restart your computer, then before windows starts up (during POST) press 'Del' repeatedly.
What differenace between bios and UEFI?
BIOS stands for Basic Input/Output system. UEFI stands for Unified Extensible Firmware Interface. BIOS deals with Hardware device code but UEFI deals with the firmware level.
How do you disable SMART in BIOS?
1. Enter BIOS, clicking Del on POST. 2. Enter Advanced BIOS Features. 3. Enter HDD S.M.A.R.T capability. 4. Click on disabled. Of course, different mother boards may have different functions organization; it is necessary to read the specific instructions manual.
