title: Drawing a line in a 1024-lines mode
body: <p>I am trying to get a line drawn in video mode 105h using <code>int 10h</code>.</p>
  <p>When I try:</p>
  <pre><code>mov cx, 10  ;col
  mov dx, 10  ;row
  mov ah, 0ch ; put pixel
  </code></pre>
  <p>nothing is displayed on screen.</p>
  <p>The mode I try is 1024x768.<br />
  I understand that I need to create a font file to get text on the screen.<br />
  But that won’t be a problem when I get the line or a pixel working.</p>
  <pre><code>BITS 16
  ORG 100h
  mov ax, ds
  mov es, ax 
  ;Set video mode
  mov ax, 4f02h
  mov bx, 105h
  int 10h
  ;Wait for key
  xor ax, ax
  int 16h
  ;Restore DOS text mode
  mov ax, 0003h
  int 10h
  ;Exit
  mov ax, 4c00h
  int 21h
  modeInfo    TIMES 256 db 0
  </code></pre>
