OSDev.org

This OS boots from FD or HD into an editor. You can branch there to a copy- or a menu-mode using the F-keys. Drivers for FD and HD, written new from scratch are added. You can use simple filesystems, which are installed in just a second. You can start Your own programs or add Your own procedures.
If You add Your own operating system interrupt, You could have a complete OS, running in protected mode.

I wrote the program to test my machine, and code and to edit special files, needed for the mature OS, which is under construction.
But I made the source fit for tutorial purpose too and wrote a lot of comments. Thus it will be very useful for those, who start learning assembler or start writing their own assembler OS.
A lot of questions, asked here in the messageboard are answered,
a lot of things, You worry about, are done already!

p.s. F?r deutsche Leser ist viel deutscher Kommentar im Programm enthalten. Ausserdem ist deutsche Dokumentation aus meiner Feder in mehreren weiteren Dateien verpackt.[/u][/quote][/code][/list][/list][/url]

Is the operating system in english? Also did you code the whole thing in assambeler?

there is another total assembly code OS calles Tabos at

www.tabos.org

All comments are in english and some are in german too. But the documentation I provided is in german.
But if You have a special question for docs - ask me!

Thanks for the hint to tabos !
tabos is meant to start C-programs and uses ELF-linking.
My OS is meant to start assembler programs without linker-headers.
