A FreeDOS modification (for mostly demonstration and playing around for fun) with the inspiration of roughly replicating an operating system called 'HEL OS' from the game High Entropy: Challenges. Just for fun, and I think I gotta beat this game. This is initially written as a rough collection of .bat files, arranged into their own folders, and after there, they have been merged into a floppy disk edition of FreeDOS, with modified AUTOEXEC.bat, .sys file and more to fit the desired target system file structure.

Every new major update is anticipated to be released each 3 months, starting from Jul 18, 2022 (the original initialisation day).

Notice: Currently I have a temporary suspension on this project, because I have many other things to do, and this project seems boring over time. I may not publish major changes every 3 months, as well as other small fixes anymore, but sometimes I can do so perhaps. Interested? Fork it and do WTF you want. (Yes, the WTFPL)

This is a simple FreeDOS modification which aims to partially simulate a very basic and rudimentary UNIX commands or "HEL OS" compatible while still in DOS base. Some commands such as whoami or uname are added and written from scratch. A number of added .bat files replicate what is inside the \system\base folder, as well as other random stuff. AUTOEXEC.bat, SHELL.bat (formerly SETUP.bat) and a config file have been modified too, to arrange things to work as desired.

Since this is FreeDOS so it's fairly compatible with normal DOS programs. With .bat file imported from DOS, you may need to rewrite something (mostly related to general commands such as 'copy' or 'move') to the corresponding ones in HEL. Other logical execution such as var defining, if-else function, while function and more are intact, to the DOS side, so you can continue using them normally.

To say again, this is a personal fun project, you can do anything but don't take it seriously. Yes.

Uhhh, perhaps the system commands has the .exe format (but I used .bat instead for easily), so I assume it's mostly DOS-based. I'm just a wet step into the UNIX world, so I donno how to write a bash script yet. Beggin' pardon, need your sympathy. Yet maybe one day, someone will eventually do that... no idea.

It stands for "High Entropy Labs", probably its original developer. The current HEL OS version in the game is 1.15, copyrighted High Entropy Labs in 1994.

The FreeDOS system included in this repository is a floppy disk version of it. It has a relatively basic functioning, and lacks many things to be a stable and really usable installation. So you can't just run your favorite DOS games here--you'd need more.

De facto you can't just copy those to a FAT32 formatted disk and see it works. This is an underway work anyways, so I'll gotta tell about this later. Curious and wanna tryna bit? You can download the source, copy those to an existing DOS system, whether MS-DOS or FreeDOS, and remember to rename the DOS system folder to system as defined in the autoexec.bat file (confliction may occur; overwrite them over to create the only system directory).

This sample of operating system can be done anything on. Deployment of the OS on some serious tasks is testing.

If you even but really understand what is this and why are you here, then feel free! I am actually very far from even writing a decent Batch script or making a DOS program. So if you can, you can. Do anything you want to improve this thing, or just leave it alone. That's up to you. I rarely make changes upon this nowadays.

This repository is released under WTFPL. It's simple, fast, neat and GNU GPL compatible. Do what the f*** you want to. However, you keep in mind that this repo contains precompiled binary files, and is abided to FreeDOS original licence.
