I was just wondering if anyone could help me out I wanted to create my own simple OS just as a hobbyist project and a learning experience. But I was wondering a few things I know I need to create the boot sector in asm but I want to makeeverything else in C++. So i was wondering if anyone knew how I could execute a .com file I make with c++ with my asm program that is in the boot sector. And after I create the boot sector where should I go from there thanx for any help

use C. see http://www.linux.org Thats all the os you need...
You might look into Linux. It's open source, so you can see how they've done it. Also, some of the disk utility companies like Power Quest have some info about how disks boot.
It's not impossible for one person to write a simple OS. I know someone who wrote one for a mini-computer long before PCs, and of course Linus Torvalds did it!
However, it IS IMPOSSIBLE for one person to write a good-modern GUI OS! Microsoft has something like 1000 programmers working for 3 years on each new version of Windows. It would take one programmer 3000 years! No one person has the knowledge or the time to accomplish a task like this. Then, you get the driver problem... Drivers are now written by the hardware manufacturers. They typically don't share the details you would need to write your own driver.
You should find more than enough info here: http://flashdaddee.com/forums/forumd...?s=&forumid=20
Also, check out osdev.org
yeah ive heard windows 2000 was written in 5 million lines or
something??!
Yes, but do remember that Linus Torvalds created linux by himself to lern the inner workings of minix. Of course this was far from the grandeur of todays linux, and it had many bugs and was pretty worthless, but it was a beginning.Originally posted by DougDbug

I can sympathize with your attempt to develop your own OS as a hobby and to learn the inner workings of your PC. My best advice would to grab a LFS (Linux from scratch) distro and start from there. As you'll be FORCED to edit and recompile the kernel several times, you'll no doubt become familiar with it.

You may even want to consider working with some embedded systems. You can gain a grasp on doing some very low level programming without all the hassel that an operation system entails.
You could also consider to take a look at Minix. A small open source OS. Minix was developed to teach students how an OS works.

If you take senior to grad level OS courses you will have to a least a simple one. I did!!!

Interesting! I thought that it was a rather unusual exercise!If you take senior to grad level OS courses you will have to a least a simple one.
I had to write and OS called KASH and another one in grad school.

What was the other one?

I am a signature virus. Add me to your signature so that I may multiply.
there was a link posted with the exact amount somewhere on here, think it was more like 2 million.Originally posted by pode
