QuantoOS.

An operating system experiment

Exploring operating system development from the ground up. A hands-on journey through kernels, memory management, hardware, and the fascinating world of low-level computing.

SECTION 001 / THE STORYUNDER THE HOOD ✳

QuantoOS is my exploration into building an operating system from scratch.

The project focuses on understanding how software interacts with hardware, from the earliest boot instructions to memory management and kernel architecture.

Why build an operating system?

Sometimes the best way to understand a system is to build one yourself.

QuantoOS began as an experiment in low-level programming, hardware interaction, and the fundamentals of operating system design.

What I've explored

RISC-V machine-mode boot
UART initialization
Trap handler installation
Device Tree discovery
Physical memory initialization

Early boot outputTEXT

[BOOT] RISC-V 64-bit
[BOOT] Machine Mode
[BOOT] UART initialized
[TRAP] Handler installed
[FDT] Valid Device Tree detected
[MEM] Physical memory initialized

“
The best way to understand a system is to explore what happens beneath the abstractions.
