原文
YOU WILL NEED THE FOLLOWING:
1a) FreeDOS, specifically, this image:
1b) Alternate download location:
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
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。
