     I tried it on my 386 with ET4000 video card.
     I get the top row only. In red.
     There is a 486 here today, let's see... yes.
     A red box. About 9 lines.
     Pink border on top and left.
     Black border on right and bottom.
     Syschk reports this machine has VESA VGA v1.2, Cirrus Logic GD-54xx
Kind regards, Barry
