I hope this applies to crappy DR-DOS 8.0 or 8.1 only ... oops, my FreeDOS is on FAT16. But I hope it works on FAT28 too.

NO. 100% 16-bit real mode OS. There are FreeDOS kernels for 80386, using some new features like 32-bit registers, but still run 100% in 16-bit real mode. No support for 32-bit apps in the kernel, no 4 GiB of RAM.

Check out FreePASCAL, FreeBASIC, FASM, CC386 and WATTCOM
