查了很多資料，關於linux下的查看bios的幾乎沒有，於是只能到Ubuntu官方查閱英文資料，累死老夫。終於在一篇教你刷新BIOS的帖子中看到資料。有許多廠商現在包括公用事業，都提供協助本地Linux在BIOS刷新。如果你確定要升級BIOS，最好是使用官方提供的BIOS升級工具。以為升級有風險… 好，下面說Ubuntu下的查看方法。
使用： sudo dmidecode –type bios
將顯示如下資料
# dmidecode 2.9
SMBIOS 2.4 present.
Handle 0×0000, DMI type 0, 24 bytes

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
當命令執行完畢，裝入軟盤，並復制新的BIOS升級工具。 這就是這麼簡單。 重新啟動即可。
