I did once write a DOS which took many hundreds of hours, written in C. Not as functional as DOS 6.0 was at the time, but it was a neat college project.

A windows operating system on the otherhand takes tens of millions of development hours, usually encompassing thousands of developers.

Thus to do what you propose you'll need to:
(a) Let's optimistically assume it'll take 1m man hours. So working 16/7/365 you should be finished in 2180 ish sort of time frame. You are in good health I hope?

(b) Skilz in C/C++ and assembler. Make sure you know which hardware configuration you're going to target. Which CPU family were you thinking of?

(c) The BIOS is your friend for simple stuff, be prepared to write an awfull lot of assembler when it doesn't do what you need.

(d) Intimate knowledge of hardware, you will need to write all the device drivers you know. You think that mouse you're using just magically works?

(e) Ever written a windowing system yourself? This nice caract I have here flashing as I type doesn't come free you know. You'll even have to code the loop to do that.

(f) This is perhaps the hardest .. understand that writing a Windows application in .Net that calls the Win API is not remotely similar to the monumental and derranged task of writing your own OS, since it's patently and painfully OBVIOUS to all that it's running on an OS and the calling that damn OS' shutdown method ... seeesh.

*Final word - no further response shall be forthcoming*


I'm largely language agnostic

After a while they all bug me D'Oh! | :doh:
