BIOS - Basic Input Output System | Tentang BIOS Komputer dalam Bahasa Inggris
The BIOS (Basic Input/Output System) is the first software that runs when a computer is powered on. It detects and initializes hardware components, loads the operating system, and allows basic control of hardware like keyboards and mice. The term "BIOS" was coined by Gary Kildall to describe the machine-specific part of operating systems. The first use of BIOS was in 1981 with the IBM PC. Modern BIOS is developed by companies like American Megatrends and uses technologies like UEFI for a more user-friendly interface compared to traditional BIOS.
Bioscmos, post, boot
The document discusses BIOS, CMOS, and POST. BIOS is a small program that stores hardware configuration settings and can be accessed by pressing keys like F2 or Del at startup. CMOS is a chip on the motherboard that stores BIOS settings and keeps the system time even when powered off. POST is the Power On Self Test process that runs each time the system starts up to check for errors in components like the processor, RAM, and hard disk.
BIOS
The BIOS is located on a chip on the motherboard and initializes hardware at startup. It detects components and checks for errors using POST codes. The BIOS is stored in ROM and cannot be changed by users. To enter the BIOS setup utility, the user presses keys like Delete, F1, or F10 during startup. Common BIOS manufacturers include Award, IBM, Intel, and AMI. The booting process involves powering on, POST to check hardware, and the BIOS loading the operating system if no errors occur. POST codes help diagnose issues and are displayed as beeps, numbers, or text messages corresponding to components like the motherboard, RAM, keyboard, or hardware in general.

BIOS (Basic Input/Output System) is the low-level program that initializes hardware components and loads the operating system when a computer is turned on. It checks that devices like the hard drive, graphics card, keyboard, and mouse are connected and working properly. BIOS is stored on a chip in the computer and allows the operating system and applications to interface with hardware without knowing specific details about each component. When hardware changes, only the BIOS needs updating, not the operating system or other software.
Intro bios
The BIOS is a set of software routines that control basic hardware functions and allow a PC to boot properly. It acts as an interface between hardware and software. The BIOS performs startup checks, handles input/output functions for components like keyboards and displays, and provides an API for software. However, directly accessing hardware can provide better performance than going through the BIOS. BIOS compatibility can also vary between manufacturers, and a BIOS must match the specific hardware it will be used on. The BIOS affects system performance both through the efficiency of its own code and the level of control it provides over components.
Chapter 3 Motherboard and BIOS
The motherboard is the main circuit board in a computer that connects all the other components together. It contains the CPU, memory, ports, and expansion slots. Chipsets on the motherboard manage communication between the CPU and other components. The BIOS stored on a ROM chip controls startup and allows the computer to communicate with devices. The CMOS stores hardware configuration settings and needs a battery to retain data when powered off.
bios.docx
The BIOS is the program that runs when a computer is powered on. It performs hardware checks and initializes devices. It then attempts to locate bootable software on storage devices like hard disks or USB drives in order of boot priority set in the BIOS. If a bootable device is found, the BIOS loads and executes the boot software which takes over the boot process. The BIOS can be customized through a setup utility to configure hardware settings and set passwords and boot priorities.
Bios
The BIOS is software that interfaces hardware components with the operating system. It loads at startup and performs checks before initializing devices and passing control to the operating system. The BIOS locates bootable devices, runs self-tests, displays system settings, and provides drivers for basic input/output. It has been largely replaced by UEFI which is meant to improve on the BIOS and interface directly with Windows.

Updating the BIOS/UEFI firmware can provide improvements and support for newer hardware.
Review paper on bios vs uefi
The document compares UEFI and traditional BIOS boot modes. UEFI addresses limitations of BIOS such as a 2TB partition size limit and limited flexibility in the boot process. UEFI uses a GPT partition scheme that supports larger drives, redundant partition tables, and booting by file path rather than fixed locations. It also provides a unified user interface for firmware configuration and allocates memory to device firmware on demand. Features like Secure Boot and booting from NVMe drives are only available via UEFI boot mode. Converting from BIOS to UEFI requires changing disk partitioning from MBR to GPT and enabling UEFI mode in the system BIOS.

The BIOS is firmware that runs first when a PC powers on. It identifies hardware, runs diagnostics, and initializes devices. The BIOS comes from the motherboard ROM, expansion cards, or can be loaded from disk. It performs hardware tests, initializes devices, and loads the operating system. Major BIOS types are AMI, Award, and Phoenix. Users access the BIOS setup utility by pressing a key like F2 or Delete during boot to view and change settings before the OS loads. BIOS updates provide bug fixes and compatibility improvements to ensure optimal hardware and software functioning. The typical BIOS menu has sections for main setup, advanced, security, power, boot, and exit options.

While the BIOS chip itself cannot be upgraded, the data on a flash BIOS can be updated using special software to fix problems or add features.
BOOTING.ppt
The document discusses the booting and shutting down process of an operating system. It describes the stages of booting as:
1) The CPU passes control to the BIOS after powering on, and the BIOS runs POST checks and selects the first boot device.
2) The BIOS loads the MBR of the boot device, which contains boot loader code and partition table information.
3) The boot loader loads the user-selected kernel into memory and passes control to it to start the operating system.

How to access the BIOS ?
- 1. How to access the BIOS ? The BIOS or Basic Input Output System refers to a software program that is stored in a permanent memory (ROM) on the motherboard of a PC. BIOS is executed immediately after switching on the system. The BIOS software, also known as firmware, fits exactly to the actual motherboard and is therefore not simply interchangeable. One of the BIOS tasks is to initialize all the existing hardware of a PC and then start the operating system. Initializing of the hardware is done by POST which stands for Power On Self Test. Each BIOS provides the ability to change certain settings on the hardware. To make these adjustments, we must first enter the BIOS itself. Each BIOS manufacturer uses different key combinations for this purpose. If these combinations are then held down for a moment right after starting the computer, the BIOS then interrupts the normal boot process and the BIOS menu will appear. Commonly used keys or key combinations to access the BIOS are: DEL ESC F1 F2 or F10 Here a tip: Just after the start of the system you will often see a small message on the screen that shows you the exact key combination to access your BIOS!
