J-OS is a small operating system for computers equipped with an 8086 or faster CPU. It's easially fitted on one floppy. J-OS is partly written as an operating system tutorial, and is well commented (on Norwegian for now). Some features of J-OS:
- A Bootloader which loads the kernel and shell into memory
- A Kernel which sets up an interrupt handler to handle interrupt calls, and execute them
- A shell that accepts a few commands
- Password protection
Available commands
- CLEAR - Clears the screen
- HELP - Shows the help screen
- LOAD - Loads a program from a program number into memory
- RUN - Runs a program in memory that has been loaded by LOAD
- REBOOT - Reboots the system
- SYSINFO - Shows debug information such as CPU register contents, etc.
- VERSION - Displays the current J-OS version and copyright information
