An (almost) operating system for x86, written from scratch in C and assembly.
This is my first take on making a kernel from scratch, it's not the best, but I think it's not bad for a first try. The kernel runs in the lower half, and has a weired and inefficient memory layout, it has some syscalls even though not enough to make a usable user shell.
I tested it in
- Bochs
- Qemu
- VirtualBox
- My main machine, until I made the ATA driver
I do not trust my code, so, to avoid any data loss or any problems in general, only try this in a VM/emulator, or in a computer that you don't use and you don't have any valuable data on its storage, do NOT boot it in your main machine.
And whatever you do : I am NOT responsible for your acts, do whatever you do at your own risk
- UART serial driver
- PS/2 keyboard and mouse driver
- PATA driver
- VESA driver
- RTC clock driver
- PIT timer
- PCI enumeration
- EXT2 filesystem (read only)
- tar in initrd
- devfs
- tmpfs
- Preemptive multitasking
- ELF loading
- Pipes
- Spinlocks
