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.
