AtriumOS

Just a hobby operating system, nothing big and professional.

System Requirements

Here's an overview of requirements to run AtriumOS. Currently it is tested in
a virtual machine with the following configuration:

• CPU: x86-64
• RAM: 4 MB
• Storage: Floppy drive

AtriumOS assumes that the following BIOS services are supported:

• disk service to interact with the floppy drive (INT 13h)
• video service to change video mode to 320x200 resolution
  with 256 colors (INT 10h, mode 13h)
• general service to query system address map (INT 15h, AX=e820h)
• general service to enable the A20 gate (INT 15h, AX=2401h)

Build

To build the OS image, just run nasm AtriumOS.asm -fbin -o atrium.flp
from the src directory. NASM version 2.15.05
is currently used.
