Each motherboard has a BIOS that name, and if the BIOS is corrupted then most likely the motherboard can not be reused, unless the bios to reinstall or upgrade.
BIOS is usually stored or embedded in ROM (read only memory). Because embedded in the ROM BIOS, then chances are we can only change the existing setting, suppose we change the amount of memory used for onboard VGA type, or change the time and date, as well as to change the basic settings for the other. However, the most frequently changed and needs to be known is to change the boot sequence, and check whether there is a computer component that we install.
The function of the BIOS on the computer
In addition to controlling the hardware installed on the computer, the BIOS also has other functions including:
- Initialization (ignition), and the testing of all attached devices (in a process known as the Power On Self Test)
- Execute the MBR (master boot record) That was the first sector of the hard drive, whose function is to call the Operating System and Run.
- Set up some basic configuration of the computer (date, time, storage configuration, the configuration of the boot / boot sequence, performance, and stability of the computer)
- Help operating systems and applications in the hardware settings using the BIOS Runtime Services.
If you are going to change the bios settings, you can do so at the time of the boot process (turning on the computer), each Bios has each way to get into the bios menu, the most common is pressing del or (alt + f4). Just look at the monitor screen instructions out first time the computer starts.
