Hi! Everyone I am new in os development & writting my first kernel in c (Platform=XP) that is basically a "helo world" kernel.My queries are!
-------------------------------------------------------------------------------
1> which compiler,assembler,linker should i use?
2> I use Grub as bootloader.Later i want to write my own bootloader...Is
there any tutorial making a bootloader.
3> I want to make my kernel to take a input string and display it to screen.
how do i do this?
4> Is there any way to test my kernel from harddisk of my current os.
I use Virtual PC for testing.I just dont want to write a floppy.
5> If you have such a kernel please give me as an example.
6> Further advices are appreciated.THANK YOU!

Welcome,

I expect that you didn't read the FAQ thread as 5 of the 6 questions have either been answered or are trivial to answer.

1: see the wiki, [wiki]Category:Compilers[/wiki], [wiki]Category:Linkers[/wiki], Tool Comparison
2: see wiki
3: see wiki
4: use a floppy image instead
5: see wiki
6: the main advice is that you please use google before asking.

a "helo world" kernel

1: spell hello world correctly in your kernel... YES IT MAKES A DIFFERENCE!

1> which compiler,assembler,linker should i use?

This is debatable. Assuming you are using C++, some members use GCC with LD. Some also use Cygwin's GCC port with LD. You can also use DJGPP, or Microsoft Visual C++. ...There are other options as well.

2> I use Grub as bootloader.Later i want to write my own bootloader...Is
there any tutorial making a bootloader.

I can probably point you here as it covers creating a small 2 stage bootloader that boots a 32 bit kernel.

3> I want to make my kernel to take a input string and display it to screen.
how do i do this?

This depends on several factors. You can use the BIOS when in real mode, or develop a basic keyboard driver and video driver to render text in protected mode... dont worry about this yet until you get a basic bootloader up for now.

4> Is there any way to test my kernel from harddisk of my current os.
I use Virtual PC for testing.I just dont want to write a floppy.

Of course! I never used GRUB, so dont know how with it (I believe it does support hdd booting)

5> If you have such a kernel please give me as an example

I can post a basic example here, but a) Im on a laptop with no mouse at work..Ugh! ..And b) There is no need to--There are already alot of good examples avialble. Check out some of the previus links posted.

6> Further advices are appreciated.THANK YOU!

Just two:

1) OS Development is NOT easy. Dont expect to create anything big for a long time.
2) Good luck and try not to quit! Take it one step at a time, and never rush.

Thank you neon.Your suggestions are helpful...Thank to Combuster too,there are really great TUTORIAL for beginer specially the babystep series in wiki section.

hi,

you can write your boot loader in NASM and use Nasm compilre to compile it.
I have done the same thing.
try to switch over to the protected mode and execute your kernel .
i can send you the boot loader..
see if its usefull.
try these
