4 Types of BIOS that are Often Used and Know their Functions

Netgenz - Technology Computer and Internet | Knowing the types of BIOS that are used most often is definitely important. Don't have to operate a computer often, meet Windows and OS but don't understand BIOS.

All computer users must have often encountered these types of BIOS, without realizing it. When turning on the computer, ie before entering Windows or OS, the option to enter Setup will be displayed by pressing the F2/Del key. If you press the button then a Setup Menu will appear which contains various basic computer configurations. This view is called the BIOS interface.

This bio is included in the program that is often used to provide instructions to the hardware installed on the computer. The BIOS resides on a chip located on the mainboard. There are many types of BIOS, but this review will discuss the types of BIOS that are often used on computers.

BIOS Types: AMI BIOS

AMI BIOS is a BIOS developed and produced by American Megatrend Inc. This company comes from America that focuses on the development of computer hardware and software. The company was also founded in 1983 and is headquartered in Norcross, Georgia, and America.

So in order to enter the AMI BIOS setup, it needs to be done by pressing the Del key during the POST (Power-On Self-Test) process. Also know some of the beep codes that appear when turning on a computer using the AMI BIOS:

  • Beep 1 time: RAM is corrupt/incorrectly installed.
  • 2 beeps: RAM problem (Memory Parity Error in first 64KB block)
  • 3 beeps: RAM problem (Memory Read/Write Error in first 64KB block)
  • 4 beeps: Motherboard problem, or motherboard timer not working.
  • Beep 5 times: Processor is damaged.
  • 6 beeps: The keyboard is broken/incorrectly installed.
  • Beep 7 times: Processor Problem (Processor Interrupt Error).
  • Beeps 8 times: VGA is damaged/incorrectly installed.
  • Beep 9 times: BIOS/Motherboard problem (ROM checksum Error).
  • Beep 10 times: Motherboard problem (CMOS shutdown Read/Write Error).
  • Beeps 11 times: The CMOS battery is depleted/incorrectly installed.

BIOS Types: AWARD BIOS

AWARD BIOS is a BIOS developed and produced by Award Software Inc. This company comes from America which is engaged in the software industry and is headquartered in Los Gatos, California, America. The company was founded in 1983 which develops Computer BIOS programs under the Award BIOS brand.

So in order to be able to enter the AWARD BIOS setup, it needs to be done by pressing the Del key during the POST (Power-On Self-Test) process. Also, know about some of the beep codes that appear when turning on a computer using the AWARD BIOS:

  • Continuous long beeps: RAM is corrupt/incorrectly installed.
  • 1 long and 1 short beep: RAM/Motherboard problem.
  • 1 long and 2 short beeps: VGA is damaged/incorrectly installed.
  • 1 long and 2 short beeps: The keyboard is faulty/incorrectly installed.
  • 1 long and 9 short beeps: BIOS is corrupt/problem.
  • Continuous short beeps: PSU faulty/problem.

BIOS Types: PHOENIX BIOS

PHOENIX BIOS is a BIOS developed by Phoenix Technologies Inc. The company is headquartered in Pasadena, California, America, and was founded in 1979. In order to enter the PHEONIX BIOS setup, it is necessary to press the F2 key during the POST (Power-On Self-Test) process.

As for the beep code in the PHOENIX BIOS, it is slightly different, that is, it is not set according to the length of the beep. On phonics, the code is set with a pause. For example, the sound 'beep beep – beep – beep beep' code is 2 – 1 – 2. Also know some of the beep codes that appear when turning on a computer using the PHOENIX BIOS:

  • 1 – 1 – 4 -> BIOS is corrupted.

  • 1 – 2 – 1 -> Motherboard is damaged.
  • 1 – 3 – 1 -> RAM is damaged/incorrectly installed.
  • 3 – 1 – 1 -> Motherboard is damaged.
  • 3 – 3 – 4 -> VGA is damaged / not installed properly.
  • 1 – 1 – 4 – 1 -> an error occurred in the cache (2 levels).
  • 1 – 2 – 2 – 3 -> ROM BIOS Checksum.
  • 1 – 3 – 1 – 1 -> try DRAM recovery.
  • 1 – 3 – 1 – 3 -> Test controller keyboard.
  • 1 – 3 – 4 – 1 -> RAM problem: Failed at address line xxxx.
  • 1 – 3 – 4 – 3 -> RAM problem: Failed at XXXX it low data byte of memory bus.
  • 1 – 4 – 1 – 1 -> RAM problem: Failed at XXXX it high byte data from memory bus.

  • 2 – 1 – 2 – 3 -> ROM: copyright notice.

BIOS Types: IBM BIOS

IBM BIOS is a BIOS developed by IBM Inc. The company was founded in 1911 and is headquartered in Armonk, New York, United States. In order to enter into the IBM BIOS setup, it is necessary to press the F2 key during the POST (Power-On Self-Test) process. Also, be aware of some of the beep codes that appear when turning on a computer using the IBM BIOS:

  • No beep: The power supply is faulty/VGA/RAM is not installed properly.
  • Continuous beeps: Power Supply is faulty/VGA/RAM is not installed properly.
  • 3 times Long Beep: Keyboard problem.
  • 1 long beep and 1 short beep: The motherboard has a problem.
  • 1 long beep and 2 short beeps: VGA Card has a problem (mono).
  • 1 long beep and 3 short beeps: VGA Card has a problem (EGA).
  • 1 short beep: Normal POST and PC is in good condition.

BIOS Functions

Execute the POST (Power On Self Test) command

Before installing the operating system on the computer, the user is required to do some checking on the computer hardware and computer hardware specifications using the BIOS. This needs to be done to make sure the operating system is compatible with the computer hardware or not.

Setting Basic Configuration on Computer Device

BIOS is the part that manages and configures several devices on the computer. The way the BIOS works in the configuration of this computing device is to provide the basic information needed to be able to operate. This configuration process itself can be set according to the wishes of the computer user.

Providing Basic Information on Computer Devices

BIOS provides basic information about the interaction process that runs in each part of the computer device. An example of the information provided by the BIOS is information about the drive or memory that will be used as the operating system installation media on the computer.
