Running DOS on Behringers DDX3216 with a DIY x86-Bios from Scratch
A hobbyist recounts the technical challenges of attempting to boot MS-DOS on a Behringer DDX3216 digital mixer, which utilizes an AMD Elan SC300 processor. The project highlights the difficulty of sourcing legacy BIOS software for embedded x86 systems.
Why it matters
This project illustrates the complexities of hardware preservation and the challenges of reverse-engineering legacy embedded systems.
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.
