ManuOS is a hobby os written in C and X86 assembly. Its main goal is to be simple and easy to use. It currently supports only X86 architecture. Arm support is planned in the future. Planned to replace old 16-bit kernel with new 32-bit kernel(experimetal).
- Two editions, C and asm
- Open source
- C edition is written in C and asm, full version, recommended
- Asm edition is written only in asm, minimal version
- Currently runs in real mode, planned to run in protected mode in the future
- OS uses kernel system calls to interact with the hardware
- Kernel can be customized for different architectures
- Sector Based File System(SBSF)
- Directories are only one character long
- Filenames are limited to 12 characters
- Wuf++ interpreter
- Dices
- Calculator
- Bouncing ball
- Text editor
- Wuf++ interpreter
- Text editor
- Linux, if you use Windows you can use Cygwin or Linux Subsystem for Windows
- gcc
- NASM
- QEMU or other emulator
- Change directory to the edition you want to build, for example:
cd ManuOS-C - Build the edition: type
make(in windowsmingw32-make) - Run the edition: type
qemu-system-i386 -fda build/manuos.img - In the OS terminal, type
setupand follow the instructions, this needs to be done only once.

- bx - main register, bl mainly used
- cx - main pointer
- sp - stack pointer
- dx - temp register
- pc - program counter, instruction pointer
- + - increment main register, bx = bx + 1
- - - decrement main register, bx = bx - 1
- } - push main register to stack, [sp+2] = bx
- { - pop main register from stack, bx = [sp-2]
- . - print main register as ascii character
- , - read ascii character to main register
- & - jump to location pointed by pointer, pc = cx
- ] - jump to location pointed by instruction pointer + main pointer, pc = pc + cx
- [ - jump to location pointed by instruction pointer - main pointer, pc = pc - cx
- ! - invert main register, bx = ~bx
- > - increment pointer, cx = cx + 1
- < - decrement pointer, cx = cx - 1
- $ - print pointer as ascii character
- #[char] - load char to main register
- ( - loop start, loads dx with loop start address, dx = pc
- ) - loop end, decrement pointer and loop until pointer = 0, cx = cx - 1, if cx != 0 jump to dx
- " - swap registers, bx = dx, dx = bx
- %[char] - compare main register with char, jump if equal to location pointed by pointer, if bx == char jump to cx
- = - halt program, halt = 1
- / - add main register and pointer, bx = bx + cx
- \ - sub main register and pointer, bx = bx - cx
- @ - load zero to main register, bx = 0
- ^ - swap bl with bh, bx = bh, bh = bl
