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
The BIOS controls basic hardware functions and allows communication between hardware and software. It performs hardware checks at startup and provides standard calls that programs can use for I/O without needing to directly program hardware. However, direct hardware access can provide better performance than BIOS calls for tasks like graphics. The BIOS can be extended through additional ROM chips, and compatibility issues can arise between BIOS versions from different manufacturers.

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.
COC. 1 COMPUTER SYSTEM SPECIFICATIONS-BIOS.pptx
Computer system specifications describe the key components that determine a computer's performance, including the processor, RAM, graphics system, and hard drive. The processor speed and architecture, amount of RAM, graphics card capabilities, and hard drive speed and capacity all impact how well a computer can perform. The BIOS or UEFI firmware installed on the motherboard initializes these hardware components and allows the operating system to boot. Updating the BIOS/UEFI firmware can provide improvements and support for newer hardware.

Module 5 raw
The BIOS is software stored on a chip on the motherboard that is responsible for initializing hardware and booting the operating system. It performs POST checks and identifies hardware components during startup. The BIOS can be accessed through the BIOS setup utility to configure hardware settings like the boot order and view system information. It provides an interface between the OS and hardware and has been increasingly replaced by UEFI, which offers larger drive support and faster boot times.

How to bypass or remove a bios password
The document provides several methods for bypassing or removing a BIOS password:
1. Removing the CMOS battery to reset BIOS settings and clear the password.
2. Using password cracking software like !BIOS to decrypt passwords for common BIOS manufacturers.
3. Trying backdoor passwords built into some BIOS versions by manufacturers for their technicians. These may allow accessing the BIOS without knowing the set password.
ROM BIOS & POST
The BIOS (Basic Input/Output System) is firmware that initializes hardware components and loads an operating system. It performs a power-on self-test (POST) to check hardware and boot the system. The BIOS resides in ROM and is the first software to run when a computer powers on. It initializes devices, runs diagnostics, and loads the operating system from storage.

BIOS2-May-9.ppt
The BIOS is software that allows the CPU to communicate with devices. It contains programs called services that teach the CPU how to talk to hardware like keyboards, mice, displays and storage. The BIOS is stored in a non-volatile ROM chip on the motherboard. It includes system BIOS for hardware that never changes, and also supports changeable hardware. The chipset, consisting of the Northbridge and Southbridge, extends connections between the CPU and devices and manages data flow. The keyboard uses a scanning chip to send unique scan codes to the keyboard controller when keys are pressed.
Types of computer system error
There are several types of computer errors that can occur at different stages of booting up or using a computer. These include hardware errors like no video output, software errors from corrupted files, and operating system errors. To diagnose issues, one should check connections, review error messages, update drivers, scan for malware, and test in safe mode. Common solutions involve reseating or replacing hardware, updating software, and ensuring proper ventilation and power supply.

Assigning there are no problems with the power supply a especial wire called power good signal wire is charged and inform CPU to get up. The CPU than communication with the system ROM and starts the power on. or Switch on the computer to process CPU for next process. • POST (Power on self test) – The post is nothing but power on self test, a computer literally discover & rediscover itself every time it powers up during this process computer parts test them self to know weather they are getting proper power supply or not. – During the post the system BIOS communicate with all essential Hardware & takes them to identify them self. If any device fails to follow this identification routine it informs back to BIOS that it is facing problem than BIOS problem error codes called post error codes. – After run (alert) the CPU, it test itself (self test) the devices inside the computer is called post. – During detecting other devices, it will give error message on beep code or numeric error code, if some problems on any device. – POST ERROR CODES • BEEP ERROR CODES • TEST ERROR CODES • NUMERIC POST

SOME BIOS ERROR • Beep error code – Beep error codes are serried of beeps produced by BIOS to indicate some post problems, usually beep codes are produced in care system fails to display error on screen the main disadvantage of beep error codes that they are not same, it varied according PC BIOS manufactures. • Numeric & Text Code – Post may also display numeric test error including the nature of Hardware problems. Numeric error code are same what standardized into certain numeric code error for . Eg: numeric codes error 100-199 indicates a mother board error. • Text error code – If post get an error message from any devices BIOS can represent there errors in dire at errors statement, for eg: system may display error like floppy drive fails or key board error.
