How to know the motherboard BIOS version using the command line
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
Try this command,
sudo dmidecode | less
dmidecode
usually returns, amongst other things, a block with information about your BIOS. It should look something like this:

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.
