Motherboard/system firmware refers to the low-level software that controls a storage system's motherboard. On NetApp systems, this is also known as BIOS, CFE, or OFW depending on the model. It is similar to the BIOS firmware on a PC motherboard. To update it, one downloads the latest version from NetApp's support site and transfers it to the system's boot device (CompactFlash card) using commands like download-d or update_flash. Beginning with Data ONTAP 8.0, subsequent BIOS updates are often automatic during booting.
