hyperOS

Making a little bootloader OS to test out some assembly.

Caution

Abandon All Hope, Ye Who Enter Here This project is a work in progress and will probably stay a work in progress forever. Expect to not see many commits or updates often, as this is a project that I will easily burn out on. See my last attempt for reference.

Features

• Printing strings via function
• Handling keyboard inputs and printing characters
• Handling special keypress cases such as moving the cursor using the arrow keys, enter to move to the next line, and the backspace key to move back and delete the last character.
  Note that I am writing directly to video memory, so I am unable to actually see what is there.

Tools

To build the project, you need to have the following tools installed:

• NASM (for assembling the bootloader)
• QEMU (for running the bootloader in a virtual machine)
• VSCode is optional, you can run the commands below, but there is a tasks.json file that will run the commands for you.

As a Windows user, I installed both NASM and QEMU with winget with the command:
winget install nasm qemu
And then added C:\Program Files\qemu and C:\Users\{user}\AppData\Local\bin\NASM to my Path environment variable.

Building

With VSCode, you can build the project by pressing Ctrl + Shift + B and selecting Build from the list. This will run the build task in the tasks.json file. You can also run the following commands in the terminal:

nasm -f bin -o boot.bin boot.asm
qemu-system-x86_64 boot.bin

This will assemble the boot.asm file and create a binary file called boot.bin, then run it in QEMU.
