Hi serrrgggeee.

Welcome to the forum.

Why are you looking at code you don't understand? An OS is an advanced project. Not suitable for a beginner. You'll only frustrate yourself! I strongly suggest starting with something simpler and working your way up.

Having said that, the MikeOS page:
http://mikeos.sourceforge.net/handbook-user.html
seems to suggest Bochs for debugging. Good luck!

Best,
Frank

Dunno. Consult the Bochs documentation?

Best,

If you want to see a fully documented FAT12 bootloader in nasm, check my thread at https://forum.nasm.us/index.php?topic=2265.0

It reads a text file from the floppy (it can be very fragmented) and displays it. It is easy to change it to load and execute a second stage loader, and converting it for FAT16 or FAT32 would be trivial. I need to get back into coding and update it, my OS died when I got too ill to code.
