rockOS

Welcome to rockOS project, a hobby OS that aims to run rogue and nethack.

Currently implemented

• GDT
• IDT
• PIC initialization
• PIT timer
• Keyboard driver
• Paging and Kheap

Usage

Just grab the latest ISO from the releases and run it on a virtual machine such as QEMU or Virtualbox, bare-metal not tested.

Build

Dependencies

• a decent compiler such as gcc or clang
• grub2 (if under GNU/Linux)
• xorriso
• make
• tar

Dependencies for compiling toolchain

• wget/curl

If it is your first time building, you need to compile the toolchain first. For that, you just need to run build-toolchain.sh, which will download binutils, gcc, grub if youre on macOS, and then compile them to $HOME/opt/cross-i686 by default which can be changed from the prompt.

After you compiled the toolchain and added $PREFIX/bin to your PATH as instructed by the script, you can run qemu.sh to compile and open the OS on QEMU or iso.sh to just generate the ISO.
