This is a base template for a legacy Option ROM. It can be freely used for your upcoming projects or experimentations.

To run the Option ROM, you will need to assemble it by running the build.py script.

The assembled file will be placed under the bin directory and named option.rom. It can be tested on QEMU via the -option-rom command line option, as follows:

qemu-system-i386 -option-rom bin/option.rom

In order to run it on actual hardware, you might need to customize the code for your specific system, such as by changing the values in the src/includes/header.asm file.
