8.1 Update the XSCF Firmwareįirmware is a software program or set of instructions programmed on a hardware device. This chapter explains how to update the firmware and how to collect log data. Just make sure that once you start a firmware updater, you let the update finish, because most devices will not function if their firmware is not recognized. Keeping your firmware up-to-date is often not necessary, but it is still a good idea. You can usually find firmware updates by going to the 'Support' or 'Downloads' area of a manufacturer's website. Sometimes manufacturers release firmware updates that simply make their devices work more efficiently. CD and DVD drive manufacturers often make firmware updates available that allow the drives to read faster media. You may need to update the firmware of certain devices, such as hard drives and video cards in order for them to work with a new operating system.
While ROM is 'read-only memory,' flash ROM can be erased and rewritten because it is actually a type of flash memory.įirmware can be thought of as 'semi-permanent' since it remains the same unless it is updated by a firmware updater. Firmware is typically stored in the flash ROM of a hardware device. But how can software be programmed onto hardware? Good question. It provides the necessary instructions for how the device communicates with the other computer hardware.
