A minimalistic 16-bit operating system written in NASM for x86 architecture
x16-PRos is a lightweight real-mode multitasking operating system designed for the x86 architecture and written entirely in NASM. It features CLI, TUI and GUI interfaces, supports the FAT12 file system, and includes a large standard software suite.
Also it`s a platform for low-level programming enthusiasts to explore development for x86 operating systems.

| Distro | Command |
|---|---|
| Debian / Ubuntu | sudo apt install nasm mtools dosfstools qemu-system-x86 |
| Arch / Manjaro | sudo pacman -Syu nasm mtools dosfstools qemu-system-x86 |
| Fedora / CentOS | sudo dnf install nasm mtools dosfstools qemu-system-x86 |
Only NASM, mtools and dosfstools are needed to build the x16-PRos and QEMU for running.
- Clone the repository:
git clone https://github.com/PRoX2011/x16-PRos.git
cd x16-PRos- Make build script executable:
chmod +x build-linux.sh- Build the project:
./build-linux.shThe build writes disk_img/x16pros.img (bootable 1.44 MB image), disk_img/HDD.img
(5 MB hard disk image) and the separate binaries in bin/.
Note
FOR ADVANSED USERS build-linux have special flags:
-quiet - disable all script messages, but not disable nasm's warnings and errors
-no-music - do not add music files in system build
-no-txt - do not add text files in system build
-no-boot-recomp - do not compiling bootloader, in system build using old compiled bootloader from bin/ directory
-no-kernel-recomp - do not compiling kernel, in system build using old compiled kernel from bin/ directory
-dtm - disable setup on first boot. dev testing mode.
./run-linux.shThe script starts QEMU with both floppies, the hard disk, PC speaker and AdLib sound.
By hand, with the floppy alone:
qemu-system-x86_64 -display gtk -fda disk_img/x16pros.img -machine pcspk-audiodev=snd0 -device adlib,audiodev=snd0 -audiodev pa,id=snd0On real hardware: write the image to a USB stick (or floppy) and boot in BIOS mode. On a UEFI machine turn on CSM or Legacy Boot first.
