When Drivers Must be Installed and Updatedĭevice drivers come pre-installed with operating systems (such as Cisco OEM VMware ESXi images), or they can be manually installed post-OS setup.ĭevice drivers generally need to be updated after these procedures:

Device drivers must be compatible with the firmware level of a hardware device, so that they properly communicate with each other driver and firmware functionality must match for correct operation to take place. Driver Dependence on Firmwareĭevice drivers have a strong dependence on the device firmware. 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. Background Information Driver DefinitionĪ device driver is software that is the interface between the OS and the hardware. If your network is live, make sure that you understand the potential impact of any command. 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:
