Is your device lagging, glitching, or experiencing random bugs? If so, a firmware update might be just what you need. Regularly updating your firmware is one of the most effective ways to keep your technology running smoothly and securely. In this comprehensive guide, we’ll answer two key questions: What is firmware? And what is a firmware update? We’ll also explore the benefits of keeping your firmware current and how EIRE Systems, a trusted IT partner across Asia Pacific, can help businesses manage their firmware strategy with ease.
What Is Firmware?
Firmware is specialized software embedded directly into hardware devices. It provides low-level control for a device’s specific hardware and enables communication between the hardware and the computer’s operating system or other higher-level software.
Unlike typical applications you install or delete on your computer or phone, firmware is permanent and critical to the operation of the hardware. Examples of devices that rely on firmware include:
- Computers and laptops
- Printers and scanners
- Routers and modems
- Smartphones and tablets
- Smart appliances and IoT devices
Without firmware, your device wouldn’t know how to boot, perform tasks, or connect with other systems.
Where Is Firmware Stored?
Firmware is typically stored on non-volatile memory chips, meaning it remains intact even when the device powers off. The most common types of memory used include:
- ROM (Read-Only Memory): An early storage medium that doesn’t allow updates.
- EPROM (Erasable Programmable ROM): Rewritable using specialized tools.
- Flash Memory: Today’s standard. Easily updatable via software.
In most computers, the firmware resides on a chip on the motherboard. This includes:
- BIOS (Basic Input/Output System): Initializes hardware during the boot process.
- UEFI (Unified Extensible Firmware Interface): A modern BIOS alternative that supports faster boot times and more security features.
What Is a Firmware Update?
A firmware update is a software patch issued by the hardware manufacturer to modify or improve the firmware embedded in your device. Unlike OS or app updates, firmware updates target how the hardware itself performs.
These updates are critical to maintaining device performance, compatibility, and security. They’re often used to:
- Fix bugs and errors
- Improve performance
- Enhance or unlock new features
- Address security vulnerabilities
For example, a firmware update on a router might patch a security flaw or boost connection stability. On a printer, it might add compatibility with a new file format.
Key Benefits of Firmware Updates
1. New Features and Functionality
Firmware updates can breathe new life into your devices. Manufacturers occasionally add features through updates that expand what your hardware can do, such as:
- Support for new media formats
- Enhanced wireless connectivity
- Improved user interface design
This means you get more value from your existing hardware without the need to purchase new equipment.
2. Better Performance and Stability
As devices age, minor bugs and performance issues can creep in. Firmware updates fix these glitches, resulting in smoother operation. Examples include:
- Faster device boot times
- Fewer system crashes or freezes
- Improved battery efficiency on mobile devices
3. Enhanced Cybersecurity
With hundreds of thousands of malware cybersecurity threats emerging daily, firmware vulnerabilities can become a backdoor for hackers. Updating firmware helps seal these gaps and protect your sensitive information, thereby reducing the chances of hackers gaining access to your system.
According to AV-Test Institute, nearly 100,000 new malware programs surface each day. A vulnerable piece of firmware can easily become an entry point if not patched.
4. Extended Device Lifespan
Properly maintained firmware keeps your device useful for longer. That means fewer replacements, better ROI, and a more sustainable IT strategy.
How the Firmware Update Process Works
Although some firmware updates are automatic, many require user initiation. Here’s a simplified step-by-step overview of the update process:
Step 1: Identify the Update
- Visit the device manufacturer’s official website (e.g., Asus).
- Look for a “Support” or “Downloads” section.
- Search by device model or serial number.
Step 2: Confirm Current Version
- Go to your device’s settings or system information tab.
- Note the current firmware version installed.
- Check if a newer version is available.
Step 3: Download and Install
- Carefully download the exact update file for your device model.
- Follow the on-screen instructions to install it.
Step 4: Reboot
- After installation, the device typically reboots to finalize the update.
Common Risks During Firmware Updates
Despite their benefits, firmware updates can be risky if not handled properly. Missteps could lead to device failure. Risks include:
- Incorrect File: Installing the wrong firmware can cause the device to malfunction or stop working altogether.
- Power Loss: Losing power during installation can corrupt the firmware.
- Security Software Interference: Some antivirus tools may mistakenly block the firmware update process.
- Irreversible Failure: In some cases, a failed update cannot be recovered. The bootloader or flash memory can become corrupted, preventing the installation of new firmware and effectively bricking the device.
For businesses managing dozens or hundreds of devices, the stakes are even higher. A single failed update can result in productivity losses, data compromise, or disruptions to customer service.
