Ubuntu: How to know the motherboard BIOS version using command line


I want to know the BIOS version of my motherboard...

The command dmidecode give you some info about the bios but i can't find what i need...

So anybody can help?!

I tried dmidecode command before asking and I didn't find what I need - I want only the BIOS-Version and nothing else in the output


I got the solution.

Using dmidecode (of course), but the problem was with the result...

I don't want to list block result about my bios I just need the version..

The command is:

sudo dmidecode -s bios-version  

The output will just print the version:



Try this command,

sudo dmidecode | less  

enter image description here


dmidecode usually returns, amongst other things, a block with information about your BIOS. It should look something like this:

BIOS Information      Vendor: American Megatrends Inc.      Version: 0309      Release Date: 04/18/2013      Address: 0xF0000      Runtime Size: 64 kB      ROM Size: 8192 kB      Characteristics:          PCI is supported          APM is supported          BIOS is upgradeable          BIOS shadowing is allowed          Boot from CD is supported          Selectable boot is supported          BIOS ROM is socketed          EDD is supported          5.25"/1.2 MB floppy services are supported (int 13h)          3.5"/720 kB floppy services are supported (int 13h)          3.5"/2.88 MB floppy services are supported (int 13h)          Print screen service is supported (int 5h)          8042 keyboard services are supported (int 9h)          Serial services are supported (int 14h)          Printer services are supported (int 17h)          ACPI is supported          USB legacy is supported          BIOS boot specification is supported          Targeted content distribution is supported          UEFI is supported      BIOS Revision: 4.6  

The information here includes both version and BIOS revision. If dmidecode does not include that data on your machine, I'm afraid you will have to reboot and actually look at the BIOS.


Another way to reduce the DMIDECODE output is to port it to Grep and extract just the lines you want -

E.G. - sudo dmidecode | grep 'Vendor\|Version: V\|BIOS Revision\|Processor'

Inside the grep, each "or" (The vertical bar) needs to be escaped with a backslash prefix, as illustrated above.

There will probably be a few extra sundry "Versions" after the Vendor one; you should be able to figure out what's what and ignore the rest. I haven't yet figured out to eliminate these... ;-)

Bonus! Above, the processor info has also been included.
