Hi!

Putting 3 as a graphic/text mode in ax is bad.
ax should contain the subfunction, like:
0x4f02 which tells int 0x10 to switch to
the mode you've put in bx !

like:

int setmode(short mode)
{
 int ret;
 __dpmi_regs reg;
 reg.x.ax=0x4f02;
 reg.x.bx=mode;
 __dpmi_int(0x10,&reg);
 ret=reg.x.ax;
 return(ret);
}
