Hello Mervyn,
>> I tried it on my 386 with ET4000 video card. I get the top row only.
 MB> Tried it today on an old XT. No luck.
 MB> Tried it on a wizbang 130MHz Pentium (in a shop) No trouble.
 MB> Some machines accept it -

             ^^^^^^^^^^^^^^^^^^^^ really?  Same video card?
     I loaded a vesa driver for the ET4000.  No luck.
Kind regards, Barry
