MaslOS-2

MaslOS but 2

This is essentially MaslOS on the outside, but completely different on the inside. The main difference being a working scheduler and support for ELF execution!

Of course it is 64bit and boots using BIOS. And it works on real hardware!

How to use

Start Menu

You can click on the start menu button in the bottom left corner, to open the start menu.

In the start menu, you can click on the programs and it will open them.

Taskbar

• You can left click on one of the tabs to select it.
• You can middle click a tab to close it.

Desktop / Windows

• You can click on a window to select it.
• You can drag the window around by holding its top bar.
• You can also resize it, if allowed, by dragging the sides/corners.
• You can also minimize the window by clicking the minimize button.
• You cannot currently maximize the window.
• To close a window, you can click on the X button.
• You can quit the whole process of the window by holding SHIFT and pressing the close button.
• You can also close the window by pressing ALT + F4.

Mouse Capture

A window can capture your mouse. This makes sense for games and such.

You can escape the capture by pressing CONTROL and ESCAPE.

All Shortcuts

Here are all the shortcuts for quick reference: (including debug ones)

• Press F10 to open the explorer
• Press F12 to open a shell (there is a help command)
• Press F11 to redraw the desktop (eg. If you get an error)
• Press F5 to launch an empty elf
• Press F6 to launch a mini window test
• Press ALT + F4 to force close a program
• Press CTRL + ESC to escape mouse capture

How to build (Linux)

• Install qemu-system if you haven't.
• Install make if you haven't.
• Install gcc if you haven't.
• Install g++ if you haven't.
• Install binutils if you haven't.
• Install nasm if you haven't.
• Install xorriso if you haven't.

Go into the MaslOS2 Folder and run the CRUN.sh file

If you are trying this and getting weird compiler/linker errors, please let me know!

gcc and ld like to break things in newer versions for some reason. :D

How to run (No need to build)

How to run (Linux)

Install QEMU if you haven't.

Download/clone the repo.

Run the cDisk.sh file to generate an empty disk so QEMU can boot correctly.

Run the JUST RUN OS.sh file to run it!

You can also use the JUST RUN OS_KVM.sh file to run it faster if you are natively on linux.

How to run (Windows)

QEMU

Install QEMU if you haven't.

Add QEMU To your PATH variable. If you need help, click here!

Then download/clone the repo and run the run.cmd file

Other

You can also boot the ISO in other software like Virtualbox and it tends to run way faster there.

Hardware

You can flash the ISO to a usb drive using tools like Rufus and if you are lucky, your device should boot MaslOS2 fine.

NOTE: As MaslOS2 uses PS/2 for mouse and keyboard input, it could happen that you cannot use it without actual PS/2 devices if your bios does not emulate them.

Contributing

I am still working on quite a few things that need to be done for MaslOS2 to be in a good state.

Meaning that not everything is 100% implemented yet and some needed things could be missing.

The Docs can be found here.

If you want to contribute by adding your own little apps/tools/games/ports I would be very happy!

If you need any help / have any questions or are curious about MaslOS2, feel free to contact me per discord. (@marceldarcel)
