In an otherwise Line Feed dominated text file, there is an anomalous sprinkling of Carriage Return (0x0D) characters throughout parts of the README file.

After an optimization, the service list and the 55AA signature are not copied to osbase. This behavior was relied upon by format. Here's a hexdump excerpt:

The command enter doesn't clean up code buffer before you use it. If you enter a large program (e.g. 512 bytes) and then a small program (e.g. 10 bytes), the second program will be a copy of the first program with some changes.

You can just add a int 0x19 at the end of the enter code.

I'm the maintainer of the mine game linked in the README (https://gitlab.com/blevy/boot-sector-minesweeper). Thank you for including it! The version in the repo was just a prototype but the game is finished now. The gitlab repo is now a mirror of the official repo here: https://github.com/io12/BootMine. It would be awesome if you could update the README link and game files. Thanks.

Why can bootOS not read files from a USB stick if i copied it onto and boot?
Everytime i enter a command it stops working and shows a blinking cursor.
Example:
$dir

Is this open source?

I'm trying to format in order to initialize the emulated disk, however when I type 'format', nothing happens.

It is unclear in the documentation if you should enter the boot sector or the com file as a bootOS program. Maybe you need to make a custom version just for bootOS.

fbi launches fbird. Builtins are the other way around: dirxxx works.
