View BIOS information in Ubuntu

I checked a lot of information about viewing bios in linux, so I had to go to the Ubuntu official website to check the English documents. Finally, I saw the information in a post that taught you to refresh the BIOS. Many vendors, including utilities, provide assistance to local Linux in BIOS refresh. If you are sure you want to upgrade the BIOS, it is best to use the official BIOS upgrade tool. Think upgrade is risky... Okay. The following describes how to view images in Ubuntu. Use: sudodmidecode-typebios will display

You will need the following:
1a) FreeDOS, specifically, this image: http://www.fdos.org/bootdisks/autogen/FDOEM.144.gz
1b) Alternate download location: http://www.mediafire.com/file/26md8h... E/FDOEM.144.gz
2) New BIOS image + flashing tool to be found at the web site of your motherboard/BIOS/OEM vendor.

M1: FLOPPY
Unpack FreeDOS image → copy image to floppy disk → create temp floppy dir → mount floppy → copy flashing tool and new BIOS image to/tmp/floppy (see footnotes below) → reboot following vendor instructions
Note: "NewBiosFiles" listed below is false code for the extracted location of the new BIOS image + related files that you just downloaded

Wget http://www.fdos.org/bootdisks/autogen/FDOEM.144.gz
Gunzip FDOEM.144.gz
Dd if = FDOEM.144 of =/dev/fd0
Mkdir/tmp/floppy
Sudo mount/dev/fd0/tmp/floppy
Sudo cp ~ /NewBiosFiles/*/tmp/floppy

After the command is executed, mount the floppy disk and copy the new BIOS upgrade tool. This is so simple. Restart.
