Yes, you can call video modes with int86 (). Here is a routine to do that:

#include <dos.h>

union REGS r;
...
void CallVideoMode (short mode)
{
    r.h.ah = 0x00;
    r.h.al = mode;
    int86 (0x10, &r, &r);
}

As you can see, you use interrupt 10h to call display services.

 

Thanks


This is what i was expecting for ......
