📦 a.out Parser: Parses legacy MINIX executables.
🛠 8086 Disassembler: Converts 16-bit instructions into an IR.
💻 MINIX Emulator: Interprets and executes 8086 MINIX binaries in a simulated environment.

Usage

To compile and run the tool, use Cargo:

cargo build --release

Or run it directly:

cargo run -- --help

CLI Options:

$ cargo run -- --help
Simple prgram to diasm and interpret Minix binaries                    
                                                                       
Usage: minix-8086-rs [OPTIONS] <COMMAND>

  disasm     Disassemble the binary into 8086 instructions             
  interpret  Interpret the binary as 8086 Minix                        
  help       Print this message or the help of the given subcommand(s)

  -p, --path <PATH>  Path of the binary                                
  -h, --help         Print help                                        
  -V, --version      Print version

Examples

Disassemble a binary:

cargo run -- disasm -p ./a.out

Interpret a binary:

cargo run -- interpret -p ./a.out

Status

This project is under active development and primarily used by me to explore some Intel disassembly and learn some more Rust. Expect bugs and some missing features.

Documentation

For the implementation of all instructions I used the Intel "8086 16-BIT HMOS MICROPROCESSOR" Spec, as well as this overview of all Opcode variants used in conjunction with this decoding matrix.
