    C OS Development

    This is an open discussion on creating a completly c based operating system. No code, just curious on whether it is plausable on a minor scale. Is it possible for anyone to create a hobby OS somewhat like Contiki OS. Perhaps even a simple (comparitively) commmand line based OS. Let us discuss on generally and specifically. By the way I am an idiot, let it be known now, so that the question of my idiocy need not waste your precious time.

    Well you cant make it all in C it just doesn't work that way. But I don't see why you couldn't make a simple command line os for hobby if you were deticated. http://www.osdev.org/

    I don't think so. To begin with you need to write a boot loader which needs to be written in assembler for the chip you are running.

    it would require such tedious low level work.

    but how about building more of an os layer upon something like the DosEmu project, just as the FreeDos project did; building another layer upon something prebuilt.

    lilo, grub two bootloaders not written in assembler.

    but you are right in that assembler is required in an os.
    the device drivers should be in assembler just for the speed.

    linux kernel itself is written in c, with assembler.

    You'll find that lilo is written in a mixture of assembly language and C, as is grub. The Linux kernel (and other *nix-like variants) are generally written in C, with a very small amount of assembly language for critical system dependent tasks, this doesn't necessarily always include device drivers; most linux and *bsd drivers, for example, are written purely in C. The main reason for this is to make porting the whole system to another architecture relatively easy.
