os-shell

Updated Shell + kernel: https://github.com/srpcd/teros

A basic shell OS made in assembly. Can be booted as an OS.

Note: Some things may not work on VMWare, VirtualBox or any real machines. This is because it can't read pointers from the bootloader.

What I used

• Make (downloaded from chocolatey)
• NASM (Assembler)
• QEMU (Emulator)

How to install

To install it, downlaod NASM from here:

• https://www.nasm.us/

To test it, download QEMU from here:

• https://www.qemu.org/download/

To make things easier, install the make command from chocolatey

• https://chocolatey.org/install

Then run cmd as admin and do: choco install make

Commands

• help (sends the help message)
• cls (clears the screen)
• exit (shuts down the OS. this won't work on VMWare or anything. If it doesn't work, it halts the CPU.)
• hlt (Halts the CPU (disabling it) and forcing you to make a system restart)

If you type an invalid keyword it will say "Invalid command".
