Need help with a project

[schilcote]

Well, I've decided to write an operating system. Not windows, nothing that complex, I just want to learn portable C and always wanted to write an OS. So who will help me?

[Yugi]

Sounds interesting, I've been looking to become involved in such a project for the experience.
Do you have MSN or similar? If so mine's kierangm[ATE]gmail[DAUT]com

[schilcote]

Okay Yugi, you've been added to the team. My email (I think that's what you mean) is Schilcotejr AT msn DOT com. Here's the code so far (don't laugh!)

Code: Select all

#include <dos.h>

int main ()
{
    _AH = 0x0A;             /* Specify that we want service number 0Ah */
    _AL = 'H';              
    _BH = 0;                /* Screen page 0 */
    _CX = 1;               /* Repeat the character ten times */
    geninterrupt (0x10);    /* Call interrupt 10h. */

	_AH = 0x0A;             /* Specify that we want service number 0Ah */
    _AL = 'e';              /* (ASCII 42 dec = '*') */
    _BH = 0;                /* Screen page 0 */
    _CX = 1;               /* Repeat the character ten times */
    geninterrupt (0x10);    /* Call interrupt 10h. */

    _AH = 0x0A;             /* Specify that we want service number 0Ah */
    _AL = 'l';              /* (ASCII 42 dec = '*') */
    _BH = 0;                /* Screen page 0 */
    _CX = 2;               /* Repeat the character ten times */
    geninterrupt (0x10);    /* Call interrupt 10h. */

	_AH = 0x0A;             /* Specify that we want service number 0Ah */
    _AL = 'o';              /* (ASCII 42 dec = '*') */
    _BH = 0;                /* Screen page 0 */
    _CX = 1;               /* Repeat the character ten times */
    geninterrupt (0x10);    /* Call interrupt 10h. */

	
	
    return 0;
}

EDIT

Does anybody know of a C compiler that can generate .bin files? I can't get DMC to do anything but exe files.

[Yugi]

Thanks ^_^ Keep in mind I'll mostly be bugtesting; I don't know if this is the sort of thing you're looking for?
Of course I can always learn to help with coding and such, it is experience I'm after

P.S. There is of course the matter of money, of which I want none

[schilcote]

Good, because I have none!

I still need to find a way to get my compilers (I have some GCC port right now called MinGW in addition to DMC) to output binary files, which DMC doesn't want to do. I'll experement with MinGW a little, and if that doesn't work, I'll have to do some more googling.

[Yugi]

Any update?

[schilcote]

Not really. But I did find a program that will strip my EXE files into BIN files. Maybe I'll look at some Linux code and try to figure out how it works.
