It’s no secret that firmware is a critical part of any motherboard. What may not be so well known, however, are the different types of firmware that may be used. In this blog post, we’ll take a look at two such types: BIOS and UEFI.
We’ll discuss the pros and cons of each type and help you decide which one is right for your motherboard. So without further ado, let’s get started!
What Is Firmware?
Firmware is a type of software that is stored on hardware devices such as motherboards. It provides instructions for how the device should work and is essential for the proper functioning of the device. Firmware updates are released periodically in order to improve performance or fix bugs and security issues.
Different Types Of Firmware May Be Used On Motherboards (Uefi Vs Bios):
There are two main types of firmware that may be used on motherboards: BIOS and UEFI.
BIOS (Basic Input/Output System) is a type of firmware that has been used for many years. It is stored on a ROM (Read-Only Memory) chip on the motherboard. UEFI (Unified Extensible Firmware Interface) is a newer type of firmware that has slowly been replacing BIOS. It is stored on a flash memory chip on the motherboard. Let’s explain in detail!
UEFI (Unified Extensible Firmware Interface):
UEFI is a must-have for anyone with a computer. Every new device comes with it pre-installed, and for good reason. UEFI replaced the legacy BIOS and brought with it a slew of amazing abilities, like being able to run remote diagnostics on the system even without any operating system. Plus, UEFI can utilize large disk partitions of over 2TB.
With systems that have UEFI, you’ll have a flexible pre-OS environment, multi-language support, and GUI capabilities. Not to mention, network support is top-notch. Critics of UEFI say that it doesn’t take away the initial problem of requiring two different drivers. But overall, this is an excellent firmware that every computer should have installed.
BIOS is a firmware that is used to start your computer when you turn it on. It also controls the CPU and how other components of the computer communicate. Although it has some limitations, BIOS is still a useful firmware for older motherboards. It can’t recognize drives larger than 2TB, but it’s an all-text menu setup program that is easy to use.
The BIOS is a firmware used to perform hardware initialization during the booting process (power-on startup) and also provides runtime services for operating systems and programs. The BIOS is stored on a ROM chip on the motherboard. The BIOS is the first software to run when a computer starts up.
It performs a power-on self-test (POST) to check for hardware errors and then loads the operating system from the hard drive or another boot device. The BIOS includes instructions on how to load operating system files from storage devices such as hard drives, floppy drives, and optical drives. The BIOS also provides basic input/output functions that allow the operating system to interface with the keyboard, display, and other peripherals.
The BIOS is essential for the proper functioning of a computer. If the BIOS is corrupted or damaged, the computer will not be able to start properly. For this reason, it is important to keep a backup copy of the BIOS in case it needs to be restored. Many motherboard manufacturers provide a utility that allows you to create a backup of the BIOS. You should create a backup of the BIOS before making any changes to the BIOS settings.
Uefi Offers Several Advantages Over Bios:
UEFI offers several advantages over BIOS, including:
- support for larger hard drives
- faster boot times
- improved security features
- easier to use interface
- So, should you use BIOS or UEFI on your motherboard?
- If your motherboard supports UEFI, we recommend using it over BIOS. However, if you are using an older motherboard that only supports BIOS, then you will need to use BIOS.
- There are a few things to keep in mind when deciding which type of firmware to use:
- Your motherboard must support the chosen type of firmware
- UEFI requires a FAT32 formatted boot drive, while BIOS requires an MBR formatted boot drive
- You will need to reinstall your operating system if you switch from BIOS to UEFI (or vice versa)
How To Update The Motherboard Firmware Bios/uefi?
Keep your PC running smoothly with regular BIOS updates. However, beware that these updates can sometimes cause unforeseen problems. It’s important to only update your BIOS if there’s a specific reason to do so, like fixing a bug or improving performance.
Knowing which BIOS you have and what version it is will help you determine if an update is necessary. Keep in mind that many manufacturers only make small changes with each new BIOS release, so an update might not be worth your while unless there’s a significant improvement.
So, what are the two types of firmware? BIOS and UEFI. BIOS is older and more limited, while UEFI is newer and has more features. Most motherboards come with BIOS pre-installed, but you may be able to upgrade to UEFI if your motherboard supports it.
In general, if you have a newer computer or motherboard, it’s recommended that you use UEFI instead of BIOS. However, if you have any problems using UEFI on your system, you can always switch back to BIOS. Have you ever worked with firmware before? What was your experience like?
