Managing Firmware with the FortiGate BIOS : Accessing the BIOS
 
Accessing the BIOS
The BIOS menu is available only through direct connection to the FortiGate unit’s Console port. During boot-up, “Press any key” appears briefly. If you press any keyboard key at this time, boot-up is suspended and the BIOS menu appears. If you are too late, the boot-up process continues as usual.
