How do I find out BIOS version using a Linux command line option?

10:50:00 PM Mahesh Kumar Yadav 2 Comments


To find out BIOS version under Linux operating systems use the dmidecode command which is a tool to analyse BIOS data. I have tested on 'Dell 3542 i5 4th Gen'. You must login as admin to run dmidecode command:

sudo dmidecode | less

Output

 # dmidecode 2.12

# SMBIOS entry point at 0x000f04c0

SMBIOS 2.8 present.

45 structures occupying 2092 bytes.

Table at 0x000EC720.

End Of Table

 



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 safeness, this also makes the presented information possibly unreliable. The DMI table doesn't only describe what the system is currently made of, it also can report the possible evolutions (such as the fastest supported CPU or the maximal amount of memory supported). SMBIOS stands for System Management BIOS, while DMI stands for Desktop Management Interface. Both standards are tightly related and developed by the DMTF (Desktop Management Task Force). As you run it, dmidecode will try to locate the DMI table. If it succeeds, it will then parse this table and display a list of records
