    Hi Prachi,

    BIOS files are included in Junos itself. There is no need to use external files. You can check which BIOS is installed and which is available to install with your current Junos release using the command "show system firmware". Newer Junos releases may be shipped with newer BIOS versions included, available to install.

    If a new BIOS is available, you can install it using "request system firmware upgrade re bios" and for the backup bios use "request system firmware upgrade re bios backup". Use "show system firmware" during upgrade to monitor if the upgrade went well.
