# Boot sector application collection

A collection of simple boot sector applications written in NASM for IBM

PC-compatibles.

# Why?

I got a little bored with my current big project and wanted to refresh my

assembly knowledge too.

# Usage

  - `./start.sh [application name]` will assemble the app and run it in QEMU

  - `./flash.sh [application name] [block device]` will assemble the app and the

    bootstrap script and flash them to the specified block device

# System requirements

80386 and a VGA-compatible graphics adapter (i.e. anything that was made in the

last 30 years).

# Application list
