Firmware is stored in non-volatile memory, such as ROM, E rasable Programmable ROM (EPROM), or flash memory. Device driver software is installed on the OS, whereas firmware is lower-level code that is installed on hardware devices. Redundant Array of Indepent Disks (RAID) Controllerĭevice drivers are different from firmware.Fibre Channel Network Interface Card (FNIC).Here is a list of hardware devices that require device drivers: The device driver translates general OS commands into specialized commands for a particular device, which allows the OS to communicate with hardware devices. If your network is live, ensure that you understand the potential impact of any command.' Background Information Driver DefinitionĪ device driver is software that is the interface between the OS and the hardware. All of the devices used in this document started with a cleared (default) configuration. 'The information in this document was created from the devices in a specific lab environment. The information in this document is based on these hardware platforms: Virtual Machine-ware (VMware), Windows Server, or Linux Operating Systems (OS).Cisco Integrated Management Controller (CIMC).Prerequisites RequirementsĬisco recommends that you have knowledge of these topics: This document describes how to install device drivers on the Cisco Unified Computing System (UCS) for common operating systems.
