"It is very special"
A hobby OS to help me learn about kernel stuff, to eventually get into linux kernel developement. Currently it supports: + booting in higher half + paging + memory management + handling IRQs + 80x25 text mode + serial output + PS/2 keyboard + PS/2 mouse + PIC timer + usermode process loading + preemptive multitasking + VBE graphics + window management + custom GUI toolkit + ext2 support
I aim to make the code readable and well-organized. A blog follows the development of this project, here https://jmnl.xyz/, and the wiki provides more information about the project and its internals.
Install the following packages:
clang+ development packages, e.g.
base-develon Archlinux (optional)
to build the cross-compiler needed to compile SnowflakeOS. This command will download and run build scripts for
binutilsfrom GNU FTP servers, and install the cross-compiler in
Instead of building your own toolchain, you can compile SnowflakeOS with your system's
clang: simply uncomment the following group of lines in the main
#### Using a preinstalled cross-compiler
If your distro provides you with a cross compiler, you may want to save time and use it. To do so, you must edit the following variables in the main
Makefileso that they match the executables of your cross compiler:
AR=$(HOST)-ar AS=$(HOST)-as LD=$(HOST)-ld CC=$(HOST)-gcc --sysroot=$(SYSROOT) -isystem=/$(INCLUDEDIR)
You may edit
HOST, or hardcode the executables names directly.
make qemu # or make bochs
to test SnowflakeOS in a VM. See the edit/debug cycle for more options on how to compile and run SnowflakeOS.
Testing this project on real hardware is possible. You can copy
SnowflakeOS.isoto an usb drive using
dd, like you would when making a live usb of another OS, and boot it directly.
Note that this is rarely ever tested, who knows what it'll do :) I'd love to hear about it if you try this, on which hardware, etc...
Contributions are most welcome, in any form! Consult
