|
Background Information
|
|
chaOS (pronounced as Kayos) is a 16-bit x86 based real mode OS.
I started chaOS development in December 2000 and the sole purpose of
developing an OS was to learn the internals of OS development because it
is something that has always amazed me. As of now i have a minimalistic x86
based real mode OS ready. The bootloader is written in NASM assembly and
kernel is written in C++. Due to my work priorities and other constraints
i could not spend a lot of time on it. But i plan to restart its development
again in near future once i am done with a hardware emulation project i am
currently working on.
