I own a PC's limited AT and an ATI EGA wonder.

I am having a great deal of trouble with the MSC 5.0 graphics library.
I can't seem to get it to do anything in the EGA mode.

_setvideomode(_ERESCOLOR);

does absolutely NOTHING.

Yet

union REGS in,out;

main ()
{
     in.h.ah=0;
     in.h.al=16;
     int86(16,&in,&out);
}

Sets me up in EGA mode 16 (16-64 color 640X350) no problem.

If I do this and then try using any of the graphics functions like
_lineto

or 

_floodfill

none of them have any effect in EGA mode (even if I set it with _setvideomode
AND do the int86 call to the BIOS so that any environment variables that
MSC sets also gets set) none of the line drawing functions work.  HELP I
have a project that I need to get done and I have been holding off buying a
graphics add-on in anticipation of the arrival of MSC 5.0 (it damn sure took
long enough and the jerks cashed my check in July when I ordered).  Is
anyone else having this problem or is it just my setup?
Some more information I HAVE used _setcolor and _setfillmask so that "ain't"
the problem.
