  - James A. Molloy’s Kernel Tutorials - One of the popular OS development tutorials in the past. It is not recommended to follow this tutorial because it has so many [issues and known flaws](https://wiki.osdev.org/James_Molloy%27s_Tutorial_Known_Bugs) that have not been corrected.
- Reference Projects
  - Xv6 - rev11.pdf)] - A modernized version of the classic Dennis Richie’s and Ken Thompson’s UNIX V6, written in ANSI C for x86 and [RISC-V](https://github.com/mit-pdos/xv6-riscv).
  - MINIX 1.0 - The first version of MINIX for Intel 8088 real mode. First appeared in a book released in 1986 called "Operating Systems: Design and Implementation" written by Andrew S. Tanenbaum.
  - MINIX 2.0.0 - The second version of MINIX for Intel 8088 real mode, the 16-bit 286 protected mode, and the 32-bit 386 protected mode. Appeared in the second edition of "Operating Systems: Design and Implementation" released in 1997, written by Andrew S. Tanebaum and Albert S. Woodhull.
  - MINIX From Scratch - A quick development environment for building the book versions of MINIX 2 and 3.
  - Linux 0.0.1 - The first version of Linux. This version is very simple compared to subsequent versions after it.
  - MINIX 1.5.0 - A revision of the first version of MINIX that adds support for the 16-bit 286 protected mode and some bug fixes.
  - MINIX 1.7.0 - A revision of the first version of MINIX that adds support for the 32-bit 386 protected mode and some bug fixes.
  - MINIX 3.1.0 - The third version of MINIX for the 32-bit 386 protected mode. Appeared in the third edition of "Operating Systems: Design and Implementation" released in 2006, written by Andrew S. Tanebaum and Albert S. Woodhull.
- Books
- Websites
  - OSDev Wiki - The OS development wiki and also the most commonly used resources for OS developers.
  - OSDev Forum - The OS development forum and also the most commonly used forum for talking about and helping with OS development, also part of the OSDev Wiki.
  - New OSDev Wiki - An attempt to modernize the original OSDev Wiki. Unlike the original OSDev Wiki, it uses it’s own wiki engine which uses GitHub instead of MediaWiki. It is currently WIP and not ready for use.
  - Lowlevel.eu - The German OS development wiki. Also contains most of the resources from the OSDev wiki, but in German instead of English.
  - Wiki DEVSE - The French OS development wiki. Not as complete as Lowlevel.eu or the OSDev Wiki, but still a good resource for French OS developers.
  - Bona Fide OS Development - Tutorials and papers for OS developments. This is also where Bran’s Kernel Tutorial lives.
  - The Unix Tree - Browse manuals and source codes of various versions of Unix.
