mcga/text modes

["Brian Holley" <comp_brain@Hotmail.com>]

I'm having some problems switching back to text mode after switching to MCGA 
mode.  My system locks up and I have to restart my computer.  I'm compiling 
this on Turbo C++ 3.1 and I don't know of any problems there might be with 
it.  The program will switch to MCGA mode fine, but will not switch back to 
text mode.

Thanks for the help,
Brian

#include <stdio.h>

#define RAND_MAX 255

void SetMCGA() {
	_AX = 0x0013;
	geninterrupt (0x10);
}

void SetText() {
	_AX = 0x0003;
	geninterrupt (0x10);
}

int main()
{
	int row, col;
        unsigned char color;

	printf("Setting MCGA mode, press a key\n");
	getch();
	SetMCGA();
	getch();
	SetText();
	printf("Back in text mode\n");
	return (1);
}
