Actually, VirtualBox's BIOS code is 100% freely redistributable and modifiable. Unfortunately, the only compiler capable of building it is non-Free (OpenWatcom). It turns out there's not a whole lot of interest in writing compilers targeting 8086 real mode these days. :(

Oops, you are correct. Good catch!

That is also the compiler required for FreeDOS; an effort towards creating a free replacement would be helping multiple projects.
