How to know the motherboard BIOS version using the command line
Solution 1
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:
SIX7910J.86A.0537.2012.0723.1217
Solution 2
Try this command,
sudo dmidecode | less
Solution 3
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.
Solution 4
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.

How can get the BIOS version of my motherboard?
The command
dmidecode
gives you some information about the BIOS, but I can't find what I need...
I tried
dmidecode
command before asking and I didn't find what I needed - I want only the BIOS version and nothing else in the output.-
drc over 10 yearsPlease make sure your question accurately reflects what you are looking for. In this case, you appearently are looking for a way to print only the BIOS version instead of all the information including the BIOS version.

Maythux over 10 years@drc I state that... Read the question again please i just say i want the bios version and i state that i use dmidecode but i can't find the version

drc over 10 yearsFinding the BIOS version is as easy as looking for the string Version in the BIOS Information block, as multiple answers said. If you are looking for a way to print only this version string, say so.

evaristegd almost 5 years@Maythux is wrong. I ran Avinash's command on my PC and it does indeed show the BIOS version. I can even use vim-like commands, so I'd say it's better than Maythux's answer.
