My Tech Ref Manual listing of the ROM BIOS shows that you can change the
cursor shape (and perhaps remove it altogether) with a call of INT  10H.
Set  AH  to 1. CH needs to be the start line for the cursor in bits 0-4,
being careful to zero bits 5 and 6. CL bits 0-4 are the end line for the
cursor. What I mean by 'line' is the scan line, not the character  line.
The  number  of scan lines depends on the display adaptor; it's around 8
for the color graphics adaptor and 14 for the mono  adaptor. I  am  told
you  can  even  have  a  split cursor by making the start line > the end
line.

I have tried this on my cheap PC compatible and it even  seems  to  work
there.  Hope this is of help,
