查了很多资料，关于linux下的查看bios的几乎没有，于是只能到Ubuntu官方查阅英文资料，累死老夫。终于在一篇教你刷新BIOS的帖子中看到资料。有许多厂商现在包括公用事业，都提供协助本地Linux在BIOS刷新。如果你确定要升级BIOS，最好是使用官方提供的BIOS升级工具。以为升级有风险… 好，下面说Ubuntu下的查看方法。
使用：sudo dmidecode –type bios
将显示如下资料
# dmidecode 2.9
SMBIOS 2.4 present.

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 pseudocode 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
当命令执行完毕，装入软盘，并复制新的BIOS升级工具。 这就是这么简单。 重新启动即可。
