HoundOS

The HoundOS operating system. Still in development.

Just a little hobby thing to figure out how operating systems work. I don't want to just read through another kernel (very large).

Using cfenollosa/os-tutorial for some source code.

Sorry in advance for the way I use git.

Building

You will need nasm, i686-elf-gcc, and i386-elf-gdb (if you want to debug).

Run make to build, and make run or make debug to run.

Features (Implemented and still TODO)

• 1-stage bootloader capable of loading a kernel
• 32-bit protected mode
• Port I/O drivers
• Screen drivers
• memcpy() and various string functions (very basic libc)
• Interrupts
• Keyboard drivers (in progress)
• Floppy drivers (in progress)
• FAT12 support
• ATAPI drivers
• ISO 9660
• ELF parsing
• Scheduler
• A very basic shell

Far Future (Ambitious projects that probably won't happen)

• Finish libc
• Maybe a text editor (port houndtext)
• Rewrite some basic GNU tools (coreutils)

Contributing

Go ahead and submit some PRs if you want to.

My work on this is on/off, because school and rowing.

Anything is appreciated!
