The basic input/output system (BIOS) on a computer is a simple but important program on a personal computer (PC) that helps the computer properly boot up and run an operating system (OS) during startup. BIOS drivers are typically used in reference to the program itself and how the program runs and interacts with other devices on the computer. These drivers in a computer are stored in the memory of the motherboard and allow a computer to boot up and boot properly when turned on.

When a computer is turned on for the first time, the motherboard’s BIOS is executed so that the computer boots properly. This system has basic access to the computer’s hardware, especially the mouse and keyboard, to allow the user to view and change BIOS settings for various reasons. Ultimately, the BIOS is responsible for running the operating system during startup, at which point most modern operating systems will take over the functions of the computer and the BIOS will not be used later. Older types of operating systems would use the BIOS to access the computer’s hardware, but most newer versions now access the hardware directly through drivers built into the operating system.
Just as an operating system uses device drivers to access the various types of devices and hardware installed on a computer, BIOS drivers are used to allow BIOS to use the hardware installed on a computer. BIOS and drivers are often specific to motherboard manufacturers, and while the interface may be slightly different on different systems, the overall functionality is generally similar. The BIOS settings on a computer can usually be accessed during startup by pressing “Delete” or an “F” key, depending on the specific system.
In the BIOS settings, the internal clock of a computer can be changed, passwords for starting a computer can be set, and the priority of boot drives or devices can be set. Without the proper BIOS drivers on a motherboard, the BIOS may not be able to function or access the hardware properly, which can prevent your computer from booting as it should. If the drivers are corrupted or erased, the motherboard may not be able to access the hard drive that contains the computer’s operating system and therefore will not be able to continue booting the computer.
If this occurs, the computer’s BIOS drivers may need to be restored or updated. This can usually be done via a disk included with the motherboard or by downloading a program from the motherboard manufacturer to update or flash the BIOS. Care should be taken whenever updating or changing BIOS drivers, as a power loss during this process may wipe the BIOS or damage the motherboard.
