DOS ain't dead

Flat UnReal Mode 32-bit Small OS written in FASM.

This is my old OS written many years ago.

The OS need 8MB memory and resides in HMA.

UMBPCI is used to create UMB memory.

Please provide parameters for UMBPCI in the UMBPCI.TXT file or delete this file if it cannot be used.

Cool - it runs in qemu.

However, as usual, documentation is perhaps a bit meagre. I have no idea how to write a program for your OS, and don't know if it has an API and how that is supposed to be called. Or are the programs restricted to BIOS calls and direct hardware access?
