<sect> Configuration

<p>
   The driver auto-detects all device info included memory size, so
   use the following device section in your XF86Config file:
<verb>
	Section "Device"
		Identifier	"NeoMagic"
	EndSection
</verb>
   or let xf86config or XF86Setup do this for you.

   But if you have problems with auto-detection, you can specify:
<verb>
      VideoRam  - in kilobytes
      DacSpeed  - in MHz
      MemBase   - physical address of the linear framebuffer
      MMIOBase  - physical address of the memory mapped IO registers
</verb>

<sect> Driver Options
<p>
<itemize>
    <item>"linear"        - linear framebuffer mode (default)
    <item>"no_linear"     - banked framebuffer mode
    <item>"no_accel"      - software rendering only
    <item>"hw_cursor"     - hardware cursor requested (default)
    <item>"sw_cursor"     - software cursor only
    <item>"mmio"          - use I/O space via memory map (default)
    <item>"no_mmio"       - use I/O space directly
    <item>"intern_disp"   - enable internal display (default)
    <item>"extern_disp"   - enable external display
    <item>"no_stretch"    - disable stretching of lower resolution modes on panel
    <item>"lcd_center"    - center lower resolution modes on panel
</itemize>
     NOTE: Stretching of panel image is on by default for lower panel
     resolutions.

   Options useful for special lcd mode setting (should not be needed):
<itemize>
    <item>"prog_lcd_mode_regs"       - set special lcd mode registers (2070 default)
    <item>"no_prog_lcd_mode_regs"    - don't set lcd mode registers (non-2070 default)
    <item>"prog_lcd_mode_stretch"    - force lcd mode regs if stretching is enabled
    <item>"no_prog_lcd_mode_stretch" - no lcd mode regs if stretching (default)
</itemize>
   Option for subnotebooks and other laptops with uncommon size panels:
<itemize>
    <item>"override_validate_mode" - disable LCD mode checking
</itemize>

     <bf>WARNING:</bf> Disabling mode checking will allow for invalid modes that
     could damage your LCD.

<sect> Known Limitations
<p>
<itemize>
   <item> External monitor support on the NM2070.
   <item> Banked, or no_linear mode on the NM2070.
   <item> Horizontal centering for lower than panel resolution on NM2070.
</itemize>
