Manufacturers record it in a chip and install it on a board.

Initially, the BIOS was needed to service disk drives, a monitor, a computer. Today, it performs many more tasks, including searching for the necessary partition and sector on the drive, configuring the system loader. In modern notebook models, manufacturers are increasingly using the new EFI interface instead of the BIOS. His scheme has great potential. For example, subroutines are now embedded between the operating system and the drive.

Reset must be done after the laptop is completely turned off. At this point, all devices, including the power supply, must be disconnected from the laptop. There are several ways to reset the BIOS.

1. Jumper. Find the jumper between the two pins on the board, pull it out, put it between the second and third contact for fifteen seconds, then put it back in place. The method is suitable for users who know the device board.
2. Contacts. Reset BIOS on the laptop can be done by closing a few contacts with something metallic, removing the pre-jumper. You can do this only with some models. Turn off the device, take a small screwdriver, close the two contacts for a few seconds, then turn on the laptop.
3. Battery. Find the battery that powers the motherboard. Turn off the laptop and remove the power for fifteen minutes. Then replace the battery and start the device.

After the main menu is open, use the arrows on the keyboard to change the system time (number, month, year). It is important that it is properly installed. Resetting the BIOS on the Asus laptop, for example, is practically the same as the procedure on the models of other manufacturers, so in any case, the user should not have problems. So, the basic settings:

• The Security section allows you to configure the security of the device. If the laptop is designed for home use, it does not require changes. Actual for office PCs.
• The Boot section helps to change the OS boot settings. If a CD-ROM is installed as the boot device, it will check this drive before launching the BIOS. If it does not find anything, the start will happen from the hard drive. Experts advise changing the Boot parameters. The settings depend on the motherboard. Place the cursor in front of the First Boot Device parameter, press Enter. When the new window appears, find the item Hard Disk (hard disk), confirm by pressing Enter.

It is implemented through a utility that is usually on the driver disk (supplied with the motherboard).
