The BIOS( basic input-output system) software is built into the PC, and is the first code run by a PC when powered on ('boot firmware'). When the PC starts up, the first job for the BIOS is the power-on self-test(POST), which initializes and identifies system devices such as the video display card, keyboard and mouse,hard disk drive, optical disc drive and other hardware. The BIOS then locates boot loader software held on a peripheral device (designated as a 'boot device'), such as a hard disk or a CD/DVD, and loads and executes that software, giving it control of the PC.[2] This process is known asbooting, or booting up, which is short for bootstrapping.
What else can I help you with?
When a windows computer has completed the post for each adapter card that has a bios what is the next step during the boot sequence?
BIOS reads the MBR.
What is the BIOS boot order on computer?
its what tell the computer what to boot first, it can be anything choosen by the bios, if you go into the bios you can change the boot order.
Could a bios cause your laptop to open with a blank screen or take long to boot?
It could cause it to not POST at all, but neither of those sounds BIOS related.
What are the 3 stages of Windows Vista startup?
Windows Boot Manager (bootmgr)File,Windows boot loader (winload.exe)File and the Boot Configuration Data (BCD) File
What is the purposes of boot priority in BIOS configuration?
boot priority in BIOS just specifies which drive or other boot able device to use first to boot from.
What takes control of the boot process from the system bios?
The MBR takes control of the boot process from the sytem bios.
Which step comes first in the boot process?
The first step in the boot process is the Power-On Self-Test (POST). When the computer is powered on, the BIOS or UEFI firmware initializes the hardware components and checks for any errors. If the POST is successful, the system then proceeds to locate and load the boot loader from the designated boot device.
Where is the boot priority order for devices kept?
BIOS setup
How do you bring a computer out of bios when it boots up to an older hard drive with windows 2000 on it?
BIOS is looking for a boot sector. If the disk does not have a valid boot sector at the address which is also known by the BIOS, it won't boot from disk.
How is the POST useful to the computer?
POST stands for Power On Self Test. Basically, the computer checks itself for hardware and software problems. If it doesn't detect anything, it boots. If it does, it won't boot. This is useful because before boot is the only time the computer remains in the BIOS, so it is a way the computer checks the BIOS without the user having to do anything.
What part of the computer checks all your components during boot?
bios
What loads first when you boot your PC?
When you boot your PC, the first component that loads is the Basic Input/Output System (BIOS) or Unified Extensible Firmware Interface (UEFI), which initializes hardware and performs the Power-On Self Test (POST). After successful POST, the BIOS/UEFI locates the boot device (such as a hard drive or SSD) based on the boot order settings. It then loads the operating system's bootloader from that device into memory, allowing the OS to start up and take control of the system.
