Hjortron is a tiny operating system for Intel Architecture, 32-bit. It is my way to explore the inner workings of a computer. And to learn more about low-level development.

It has a few minimal features; FAT12 (bootloader and filesystem), ATA driver, interrupt handler, keyboard driver, PCI enumeration, dynamic memory management, ELF relocation, serial port driver.

Running in QEMU with debug output in Windows (serial port).
