How Does Firmware Upgrade?
Generally speaking, in order to upgrade firmware, you will need to contact the device manufacturer. Most manufacturers can be contacted via the web, however in certain circumstances; you will have to request a CD ROM that has the firmware upgrade on it. For most consumer devices, upgrading firmware is a very simple and a convenient process. Devices that are automatically connected to the internet (for instance, a printer) can regularly check the manufacturer’s web site for firmware updates, download the firmware update and install it within the device without any human intervention. However, most devices require the administrator of the device to contact the manufacturer to see whether or not a new firmware update is available. If one is, the administrator of the device must download it and install into the device.
