Hi,

	Using the VESA 1.2 specification (I also double checked using the MS
DOS interrupt list) I wrote up the following function.. Unfortunately, on my
system, this call ALWAYS returns regs.h.al=79 instead of regs.h.al=0 which
would indicate no error has occured.

--------function follows-----------

   regs.x.ax=0x4F03;
   regs.h.ah=0x4F;
   regs.h.al=3;
   __dpmi_int(0x10, &regs);
   if (regs.h.al!=0x4F)
     setError(noSupport); //command not supported
   if (regs.h.ah!=0)
     setError(failed);         //command failed
   if (error()!=none)
     return -1;
   _mode=regs.x.bx;

------------------------------

	Please help!
