PCs and laptops
Modern PC and laptop firmware is one of the following types: the older BIOS (Basic Input-Output System), and the newer EFI (Extensible Firmware Interface). While most Windows PCs use the 16-bit BIOS, servers generally run on EFI. Apple MacBooks, MacBook Pros, iMacs, and Mac Pros also use EFI.
Usually, you can update the BIOS using the BIOS setup screen. You can copy the BIOS update file to a USB memory stick and plug it into any system that you want to update. You can manually update the BIOS by pressing the Delete, F2 or F10 key to get to the BIOS setup program.
Now, you’ll need to go to the device with the firmware update. This is usually accomplished by selecting the file name and pressing the Enter key.
The BIOS can also be updated using an executable file. You can simply download the BIOS update app and launch it from the desktop. These days, you can also find aps for updating the BIOS over the internet.
Routers and peripherals
The instructions for updating firmware of PC peripherals can vary considerably, so you will need to read up the manufacturer’s documentation usually available on their website or in the manuals that come with the product.
A router, for example, will have updates available online and you can install them only if you need to. Wi-Fi routers have an updating firmware option built into their router management interface. These updates will tell you what you can expect from them and give you an option to back out. Network-attached storage devices also use a similar interface to upgrade firmware.
Some peripherals might involve downloading an ISO image, burning it to a CD, and then booting the update from the CD to install it.
The only thing to remember is that if the peripheral doesn’t reboot automatically then ensure that you do so after you have updated the software.
