Hi all,

we can use the command called dmidecode to display the BIOS information.

dmidecode is a tool for dumping a computer’s DMI (some say SMBIOS) table contents in a human-readable format. This table contains a description of the system’s hardware components, as well as other useful pieces of information such as serial numbers and BIOS revision. Thanks  to  this  table, you  can retrieve this information without having to probe for the actual hardware.  While this is a good point in terms of report speed and safe‐      ness, this also makes the presented information possibly unreliable.

More information :      man dmidecode

Note : You have to execute this command as root.
