STARTING A NEW OS (Operating System)

[elias]

hey, you guys said you all have a whole library of links that you use for research. would you mind sharing those sites?

[Berserk]

For this 'Ben' guy, i don't know who you think you are!

If i wanted your advice i'd 'ASK' for it. As a matter of 'FACT' i am going to learn the basics of assembler later, and 'NO' it is not a *MUST*

For everybody else, thank you soo much for your help ;D

But i am only a quater way to even starting an 'OS' first i am learning some 'ASSEMBLER' and about BootSectors.

All of your helo is appreciated, and don't think i have given up if i don't post something for a long time, if i don't post anything in a long time (i.e. a couple of days to a week) i've probably got distracted, or am learning something, or writing some code, before asking any more questions

Thanks everybody,
I will ask some more questions soon, for now i got to learn some stuff!! (Assembler and some more C++ [i am also a beginner in 'C++' but i know 'A LOT' of C++, unlike assembler])

Well then, why don't you make yourself a profile here and log-in?

[Berserk]

You mean i should become a member?

[Tom]

If you would like...that way we could IM you and you could IM us

[Berserk]

I will,

Later.....When i figure out some more stuff about OS's.

i got a few more questions, i'll ask them later.....

ciao

[Berserk]

i got another question, read in another thread called started by me (at the top of the forum)

ciao

[Berserk]

Hey Hey,

I got a question, i have seen a couple of BootSectors.

And on some i see [ORG 0] and on others i see
[ORG 0x7C00] what is the difference. And also, what is it and what does it do??

And, which one is better to put??

Also, does anybody know where i can get a GOOD BootSector tutorial, to be made with nasm. I have already searched google and other search engines, and YES i have found tutorials, but they don't go into depth. I want a tutorial that explains absoloutely everything! (most of it anyway)
I am not asking you to search for me, of course not, but i was just thinking if any of you already know where to find a good tutorial??

Cya Everybody.
And help out Please.....

[Berserk]

Please help out....

Can somebody please help??

[ORG 0] means you expect your code to run at 0x07c0:0x0000, [ORG 7C00] means you expect to be run with 0x0000:0x7C00.

And, which one is better to put??

The one you prefer as long as your code is coherent. [ORG 0] has the advantage your code can be moved to another location and run there with just changing CS.
However, make sure you *enforce* at run time what you assumed at compile time : if you have [ORG 0], let your first instruction be a jmp 0x7c00:start ...
Just because you ignore which cs:ip pair the BIOS will choose for you

look for boot0.asm on this forum ... it was going more than idepth, explaining every single bit ...

it is AT&T, though :-/ but this shouldn't block you, will it ? if it does, assemble it and use ndisasm to get a more friendly version

And help out Please.....

Figuring you on your knees and begging for guru's help lol ...

It doesn't matter what one you use...it's all on how you want to make your bootsector/kernel.

My first FritzOS's kernels used the "ORG 0"..and my new ones use "ORG 0x7C00".

I think that the "ORG 0x7C00" is much more simple, otherwise you'd have to do a more complicated & confusing jmp.

Hey Pype.Clicker i read back there somewhere that you have made your own micro kernel, are you gona make it available to everyone, if so i would like to see the source, If that is possible of course.

[Pype.Clicker]

right... and despite it's not yet completely finished, you're absolutely free to start your own OS from the clicker microkernel, if it fits your requirements ... i designed it so that most of the features are customizable (or at least i tried to
