  • Firmware


    We all use electronic devices, whether they are mobile phones, computer routers, MP3 players, cable boxes, etc. These electronic devices include hardware, the physical electronic components and software, programs that help these components run effectively. Firmware is a mix of both.

    Firmware

    Firmware is usually defined as a type of program that runs within an electronic device. Firmware is not categorized either as hardware or software, but a mix of both. The reason firmware is considered a combination of both categories is that firmware employs an executable program (.exe) and includes an integrated piece of the electronic device.

    Firmware is stored on ROM chips (read only memory). Each time your computer or electronic device boots up, firmware is booted as well. Firmware can store their instructions permanently and do not require a power source. One of the most common types of firmware is the BIOS chip on your computer's motherboard. The BIOS chip holds extremely important data (instructions). For instance, when your computer is started, this activates the BIOS chip where important hardware is initialized and components are checked by the BIOS chip to ensure that devices are working properly. Once the BIOS chip has completed its duties, it sends a message to your computer's operating system which then starts up.Firmware

    While firmware is permanent, it has the advantage of being rewritten. It should be noted that older firmware did not have the ability to rewrite its instructions. In fact, in the past, when new instructions were required for a BIOS chip, the entire motherboard usually needed replacing since the BIOS chip could not be rewritten. Now, firmware can easily be rewritten enabling it to be upgraded with new features or to remove bugs and issues. Since firmware is found in practically all electronic devices, it has extended the life of these products, easily adding more functionality to them.

    Firmware Upgrades

    For the most part, in order to upgrade firmware you will need to contact the device's manufacturer. Whether your device is having issues or you would like to add new functionality to it, your manufacturer should have the latest firmware update (if available). There are two simple methods of upgrading your firmware. The first is to download the new firmware directly into your device; the second is to request the new firmware from the manufacturer (either on CD ROM or other media). With both methods, upgrading your firmware is relatively quick and easy and your new functionality or the disappearance of bugs will be immediate once installed

    Computer devices that connect directly to the Internet are by far the easiest firmware to upgrade. Just log onto the device's manufacturer's homepage and search for a new firmware update. If a new firmware update exists, you can follow the prompts to download it. Sometimes you can download it directly to your device, other times you will need to save it to your hard drive and then transfer it to your device with a special cable.

    In certain cases, firmware can not be downloaded from the internet, instead new instruction need to be inserted directly into the device, usually with the help of a memory card and card reader. One type of device that can include direct installation is the cable box or satellite receiver.
