INSTALLATION INSTRUCTIONS  
--------------------------------------------------------------------------------
To install the driver: 

1.   Open the Control Panel (Start -> Settings -> Control Panel).
2.   Open the "System" applet.

3.   Go to the "Hardware" tab.
4.   Click the "Device Manager" button.
5.   If the "Display Adapters" category is available, expand it. Otherwise, 
     go to step 6b.

6a.  Right click the adapter and select "Properties."
7a.  Go to the "Driver" tab.
8a.  Click the "Update Driver" button. (Click the "Reinstall Driver" button if
     the "Update Driver" button is not seen.) The Update Driver Wizard window
     will open. Follow the Wizard.
9a.  Select the radio button
     "Install from a list or specific location (Advanced)." Click "Next."
10a. Select "Don't search. I will choose the driver to install." Click "Next."
     Go to step 11.

6b.  Expand "Other Devices."
7b.  Right click "Video Controller (VGA Compatible)" and select "Update
     Driver."
     This will open the Update Driver Wizard. Follow the Wizard.
8b.  Select the Radio button "Install from the list or specific location" and
     click "Next."
9b.  Select the Radio button "Don't search. I will choose the driver to
     install" and click "Next."
10b. Select "Display Adapters" and click "Next."

11.  Click the "Have Disk" button.
12.  Insert the floppy disk with the driver you built into the floppy drive.
13.  Type the location of the driver files (e.g. A:\ ).
14.  Click the "OK" button.
15.  Click the "Next" button on the Wizard.
16.  Click the "Continue anyway" button if Windows XP reports that the driver
     is not signed.
17.  Click "Finish" in the Wizard. Then, if Windows XP displays a dialog box
     asking if you wish to restart, click "Yes" (recommended). There is no
     need to continue with rest of these steps if you restart Windows.
18.  Close the "Properties" dialog box if it is open.
19.  Close the "Device Manager" applet.
20.  Close the "System" applet.
21.  Close the Control Panel.
22.  Restart Windows.


Control Panel Extension
-----------------------
A control panel extension is provided to configure certain parameters of 
the driver like Compression and DDC. The details of these parameters are:

Registry Settings
The driver behavior depends upon the way is been configured. Below are 
the registry settings that change the behavior of the driver.

Compression:
This option enables the driver to enable or disable compression. Lossless 
graphics compression is a hardware feature of the Geode processor.  
Display compression has three possible driver settings:
0 - Compression is always disabled.  No video memory will ever be 
    allocated to hold the compression buffer.
1 - Compression is enabled by default.  However, if the allocation
    of video memory for the compression buffer causes a display mode
    to require more memory than is available, compression is disabled.
2 - Compression is always enabled.  If the allocation of video memory for
    the compression buffer causes a mode to require more memory than is 
    available, that mode will not be available.
		   
LinearFB:
This option configures the memory layout for the active display data.  
The display compression hardware inside the Geode processor is most 
efficient if the space allocated for a single line of display data is  
equal to a power of two.  When the size of each line is 1K, 2K, 4K, or 8K,  
each line of the display is individually compressible.  However, this leads 
to wasted video memory.  For applications that require efficient memory, or 
for applications that flip the primary display (such as games), it is often 
more beneficial to allocate only the amount of space needed for the active 
display.  There are three possible settings for the driver:
0 - The size of each display line is always a power of 2.  If the amount of 
    memory needed for a display mode is larger than the available memory,  
    that mode is discarded.
1 - The size of each display line is a power of 2 by default.  However, if 
    the amount of memory required by a display mode is larger than available 
    memory, that mode uses a linear frame buffer to fit the mode.
2 - The frame buffer is always linear.  The display is compressible only as
    a whole, leading to less efficient compression.  However, all of video 
    memory is always be available.
	      
DDCEnabled:
This option enables the driver to query the monitor for the best-supported 
resolutions. This will be disabled automatically if a flat panel is detected.

BIOSDetectOutput:
This option enables the driver to query the BIOS for the appropriate output
format.  If this option is disabled, the user must manually select the output
device.  Also note that if this option is set and a panel is detected, the driver
will not touch any of the hardware panel timing registers.

PanelEnable:
This option is used to manually enable TFT output.  If "BIOSDetectOutput" is 
set to 0, this option will force the output to be a TFT panel.  PanelWidth and
PanelHeight MUST be set to a valid panel resolution.

TVEnable:
This option is used to manually enable VOP output.  It is currently unsupported.

SimultaneousCRT:
This option enables simultaneous CRT/panel output.  It is only used when 
"PanelEnable" is set to 1 and "BIOSDetectOutput" is set to 0.

PanelWidth:
This option is used to manually specify the width of the connected panel.

PanelHeight:
This option is used to manually specify the height of the connected panel.

TVWidth:
This option is used to manually specify the desired width of VOP output.  
It is currently unsupported.

TVHeight:
This option is used to manually specify the desired height of VOP output. 
It is currently unsupported.

TVInterlaced:
This option is used to specify that the VOP output is interlaced.  It is 
currently unsupported.

XVGAPanel:
This option specifies that the connected flat panel accepts 2 pixels per
clock.

DDC_GPIOData:
This option specifies the GPIO pin to which the DDC data line is wired on
the CS5535.

DDC_GPIOClock:
This option specifies the GPIO pin to which the DDC clock line is wired on
the CS5535.
