Running DOS on Behringers DDX3216 with a DIY x86-Bios from Scratch
Key takeaways
- In 1994 I got my first computer: an Intel i486 DX2-66 with 4 MB RAM and a 512MB harddisk.
- In 2026, 32 years later, I learned from some screenshots of the DDX3216, that Behringer used a real 386 processor within this machine.

In 1994 I got my first computer: an Intel i486 DX2-66 with 4 MB RAM and a 512MB harddisk. The software was IBMs OS/2 and Microsofts Windows 3.11. In the next four years I was upgrading this machine every few months with more RAM (up to 16MB), a CD-ROM-drive and a soundblaster card. So I learned upgrading this machine, installing new software and finally learned how to program new software using BASIC. But I never got in touch with the boot-process or the details of MS-DOS.
In 2026, 32 years later, I learned from some screenshots of the DDX3216, that Behringer used a real 386 processor within this machine. Immediately, some of my neurons fired in my head and I pondered if I could boot software and even a full operating system on this device. My goal was to learn how an x86-system is booting, how DOS takes over and what is necessary to get into the shell.
