<h1><a name="kap_interrupt_0090"></a>INT 10,1 - Set Cursor Type</h1>
<p> AH = 01</p>
<p> CH = cursor starting scan line (cursor top) (low order 5
bits)</p>
<p> CL = cursor ending scan line (cursor bottom) (low order 5
bits)</p>
<p> returns nothing</p>
<p> - cursor scan lines are zero based</p>
<p> - cursor size can also be set via the ~6845~ CRT controller</p>
<p> - cursor size can be determined using the CRTC, ~INT 10,3~ or
the</p>
<p> ~BIOS Data Area~ bytes 40:60 (ending scan line) and 40:61
(starting</p>
<p> scan line)</p>
<p> - the following is a list of the cursor scan lines associated
with</p>
<p> most common adapters; screen sizes over 40 lines may differ</p>
<p> depending on adapters.</p>
<p> % Line Starting Ending Character</p>
<p> % Video Count Scan Line Scan Line Point Size</p>
