Thread: Using BIOS int 10H and int 16H

yes i am using power c compiler

here is what i have so far

Code:

//#include "libepc.h"
#include "dos.h"

int main(void)
{
	char attr1;          // any floor unlit
	char attr2;         //  any floor lit
	union REGS r;		//Holds register values for the bios services	
	int row =12;		//Screen position
	char ch;			//Character entered by the user

	//  Set Video Mode
	r.h.ah = 0x00;			//set mode
	r.h.al = 0x03;			//mode 80 x 25 16 color
	int86(0x10, &r, &r);

	// create a solid rectangle using the block character
	for(row = 0; row < 5; row++)
	{
		//	SetCursorPosition
		r.h.ah = 0x02;			//service #
		r.h.bh = 0x00;			//display page 0
		r.h.dh = row;			//row #
		r.h.dl = 11;				//column #
		//	 r.x.dx = 0x0c28;		//12rd row 40th col
		int86(0x10, &r, &r);

		//	Write some characters to screen
		r.h.ah = 0x09;			//write character

having trouble creating location #'s for my boxes and creating a statement to light them up according to what floor its on

o_O ... What is that, a unreal mode emulator??? Because you know that BIOS can't directly be used in protected mode, right?

Edit: Oh, now i get it. It's a MS-DOS emulator, hence the "dos.h"
