Guide to update the BIOS and Drivers of your Asus computer

You have decided to replace a part or adding a new peripheral device to your setup. You have replaced it and/or connected it properly, but it is not functioning or behaving strangely. The odds are that you will need to update the BIOS/Firmware or the drivers in your system. This article will help you understand what these are and how to install them.

Note: ASUS Accessories is here to help you select the correct replacement part for your ASUS device.

What is the BIOS/Firmware

Like software, the BIOS and drivers are programs that instruct the machine to carry out a task. The difference between these is their purpose: The BIOS/Firmware instructs the hardware, the drivers are like translators, and they interpret what the operating system is asking of the specific device. The software is the top layer that uses all of the devices and hardware to accomplish its designed function.

All electronic devices such as computers, mobile devices, remote controllers, gaming consoles, smartwatches, USB drives, have a BIOS/Firmware. The Firmware controls the hardware of a device. It is present on a non-volatile memory chip (NVM / EPROM) and rarely requires an update. In a PC, we call it the BIOS (Basic Input/Output System) or UEFI (Unified Extensible Firmware Interface).

The BIOS is the first thing that animates your computer when it is powered on. It is used by the CPU to perform start-up procedures when the computer is turned on. Its two major procedures are determining what peripheral devices (keyboard, mouse, disk drives, printers, video cards, etc.) are available and loading the operating system (OS) into main memory. The BIOS will initiate the BOOT program which will wake up the OS stored in your hard drive and place it in your RAM (Random Access Memory).

It initializes the hardware during the booting process, and to provide other runtime services for operating systems and programs. BIOS calls another program called a bootloader, which does the job of waking up the operating system sleeping inside the hard drive and put it in the random access memory (RAM). The bootloader is usually part of the OS software.

Before you pull your hair out….the BIOS talks/recognizes your new hardware or peripheral device. If it doesn’t, it may not function at all or may function partially. You will need to update the BIOS. If your BIOS is up to date, then you will need to update the drivers.

What are Drivers

A drivers task is to drive - control the hardware it’s designed for, example the printer. It is the go between program that allows the hardware and the operating system to communicate properly.

An operating system doesn’t come with support for all hardware present on the machine. Since components and hardware are not always built by the same company, the manufacturer has specific optimized drivers for their hardware that you install in your operating system.

Since Windows 8, Microsoft has tried to reduce driver dependency. The company pre-installs universal or generic device drivers that can work for various devices of a similar type, or delivers required drivers via Windows Update. These are not always the optimal choice for your new devices.

Application Software

This category of software ranges from anti-virus, word processor, web browser, multimedia, games and video editing software. Simply, these are the applications that you use.

Why should you update the BIOS on your ASUS

First you should know updating your BIOS will not make your device faster or keep it from overheating.

The following are good reasons to update your BIOS.

Hardware updates
BIOS updates allow the motherboard to correctly identify new hardware such as processors, RAM, and so on. If you upgraded your RAM and the BIOS doesn’t recognize it than you should update your BIOS.

Security updates
The latest BIOS updates come with security updates. In motherboards that support boot sector scanning, the new BIOS can resist boot sector viruses.

Increased stability
Manufacturers will release updated BIOS to fix bugs and issues that are present in the previous version. These bugs may affect new hardware or new peripherals substantially where they were not noticeable with the old hardware or peripherals.

Check your BIOS Version

Before updating BIOS, you need to check your current version of BIOS and compare it with the latest version on your motherboard’s support page.
