let's resurrect these days with open.mp!

How about the event loop in its completeness?

Sort of, but IMO that module(s) is just a wrapper for video buffer.

You are right, it goes way ahead the first iteration. I call it DOS-like because of its resemblance to the Text mode-only operating systems (and to MS-DOS especially). On the other…

I am not at the moment. The goal is to keep this iteration in English for now. The first iteration was in Czech in the beginning though.

Well, the point is to experiment with Rust no_std+no_main environment while trying to educate myself on how the things work under the hood. The project itself is part "just" a rewr…

NGL, the codebase of the first iteration is pretty much a mess. It had been written in my mid-teenage years, so the C code is not very consistent across the project. There is a fil…

The x86 arch is used because this system iteration derives from the first one, which relies on BIOS interrupts and inline assembly in Turbo C. I am not trying to mimic (MS-)DOS exc…

For FAT12, it reads the first sector (0 or bootsector) of the floppy provided to gather information like bytes per sector, reserved sectors count, LBA of the root directory, etc.

Booting from an EFI system partition has not been tested yet. FAT12 is the only filesystem (ok, there is a memdisk implementation, but it won't work now) supported, so GPT is not s…

Afaik there is a 'DIR' command in MS-DOS. Anyway, what would be a better command to list a directory? I could think of 'ls' maybe

What a challenge! Need to implement some interrupts it seems then, to provide an API for filesystem and so... Thank you for such idea

You are right. The first iteration however is 16bit and is very close to MS-DOS in terms of compatibility. Moreover, any OS that can handle simple disk I/O ops could be considered …

To try it out, simply build the project yourself from source, or use attached bootable ISO image of the system (in Releases on Github) and run it in QEMU. https://blog.vxn.dev/rou2…

I didn't really think this through like that, good point. Thanks for the link, will consider reposting it later https://github.com/krustowski/rou2rexOS
