Hi,

I suggest you try http://www.osdev.org/wiki/Getting_Started followed by the rest of the wiki and also articles on http://www.osdever.net/ to start with.

I know this reply itself isn't much help, but the question you asked is so broad, it looks like you need to do some general reading first. Also, acquire the Intel Manuals.

Cheers,
Adam

I made a real OS, as a basic realmode OS tut, it a dos clone (called MiniDos) in less than 2k, written in ASM, you can get it here: http://board.flatassembler.net/topic.php?t=5275

Why would you want to make a real-mode only OS?

Or maybe they want to learn stuff one step at a time?

I think we need to make a sticky thread where beginners can find answers to these types of questions (i.e How to I start OS developing?)

Basically, we need a prominent link to the Wiki...

yeah cause this is totally keepin on topic.... just ignore the creeping and it will get bored...

I defiently think we need a sticky for all the people who dont check the wiki straight away... and i advide the poster go read the wiki... then learn Assembly, hopefully in a book that talks about the BIOS, then writing it is as easy as writing a program for DOS...
