    One million dollar question

    Hello people! I need some good advice.

    I'm venturing out to make my own operating system for experimental purposes. Do I need knowledge in Assembly to do this? I'm planning to use C only but I'm not quite sure if this would suffice.

    I've read in my bios.h (I use Borland C++ 3.1) some disk write functions. I was wondering if I can use these to modify root and boot sectors.

    I'm welcoming any suggestions and comments. :

    I'm quite ambitious, don't you think so?

    yes it would be near impossible ( never say never) to not use assembly , atleast for the bootstrap. This is very very tricky, but it is also reinventing the wheel. I would use GRUB then you only have to worry about programming your kernel, not about the specifics of getting it into memory.

    I will tell you this though, me and three people worked on an os from scratch, took about 1 year, very frustrating, started looking alot like MINUX, and when we finally spun the hard disk (the greatest accomplishment of my life), we quit.

    Don't consider writing an O/S unless you are comfortable with assembly. For some reason, most developers never understand the simple yet powerful crucial fundamentals unless they learn assembler.

    That's why Microsoft writes such cr@p. Most of their developers don't know anything but C++ or Java, and voila! You have Windows XP.

    One year? Geeezuzz! And to think I know nothing about assembly language. Maybe it would take me more than that.

    Hahaha! Nice one. Yah I've read somewhere that MS uses robust languages for development. But isn't UNIX rewritten using C only?

    Why don't you pick up a book like 'Understanding The Linux Kernel', and read through it. Only do this if you are very familiar with using any OS, as well as C and C++ and to some degree assembly. Also try writing some device drivers. Again, it is best to work with Linux because you can look directly at the source code. There is no better way.

    You must be confusing Microsoft with SUN. Microsoft programmers know Java? What crack are you smoking? Java is a SUN product. They created it.

    No kidding, microsoft is trying to eliminate java from the face of the earth.

    >Microsoft programmers know Java?

    Of course they know, although I've read somewhere that Microsoft uses some other language they created for their very own exclusive use. And they use VB heavily too.

    >No kidding, microsoft is trying to eliminate java from the face of the earth.

    Yah hehehe. They probably feel it would be a menace to their OS.
