It's a small and simple OS based on:

• http://www.brokenthorn.com/Resources/OSDevIndex.html
• http://www.jamesmolloy.co.uk/tutorial_html
• https://subscribe.ru/catalog/comp.soft.myosdev

I created it using Windows 10/FASM/MinGW/Bochs/Visual Studio Code.
Development notes (currently on Russian only) are in /docs/notes.pdf.

OS uses protected mode and paging. It has:

• a simple bootloader
• switching to user mode
• simplest multitasking
• one system call (woW!!!)
• some other basic things.
