Many times, for TAC interactions or release notes about new FortiOS versions, to know the FortiGate BIOS is needed.
The best method to find the BIOS version of a FortiGate is to use the CLI console widget, as BIOS details are not typically displayed in the standard Dashboard status widget.
If the command 'get system status' is introduced, general information about the device will be shown (included the BIOS version):

To isolate the BIOS version and exclude irrelevant data, apply the 'grep' command to the 'get system status' output. The following command 'get system status | grep -fi BIOS' can be used to search case-insensitively and to mark the found line.
The grep parameter '-i' makes the search string case insensitive. The grep parameter '-f' will mark the found line with an ASCII arrow '<---'.
For example:
FGT-TEST# get system status | grep -fi BIOS
BIOS version: 05000006 <---
