How to run FreeDOS on Raspberry Pi, part 2

I expanded my other item about How to run FreeDOS on Raspberry Pi, and turned it into an article for OpenSource. Here's a recap from that:

As the founder and project coordinator of the FreeDOS Project, I'm often the go-to person when users ask questions. And one question I seem to get a lot lately is "Can you run FreeDOS on the Raspberry Pi?"

The short answer is "no" because like any DOS, FreeDOS needs an Intel CPU and PC BIOS. The Raspberry Pi doesn't have either of these. The Raspberry Pi is based on an ARM CPU, which is a completely different architecture.

But you can run FreeDOS on the Raspberry Pi if you use a PC emulator, like QEMU. FreeDOS runs fine in QEMU on Raspberry Pi, including games, but be aware that installing FreeDOS will take a long time. Actually, anything that requires a lot of disk I/O (like installing software) will be slow because the microSD storage on a Raspberry Pi isn't exactly fast.

Once you have installed FreeDOS in QEMU on the Raspberry Pi, you shouldn't notice any performance issues. For example, games usually load maps, sprites, sounds, and other data when you start each level. While starting a new level in a game might take a while, I didn't notice any performance lag while playing DOS games in FreeDOS on the Raspberry Pi.
