-----------------------------------------------------------------------------
1. Install WINDDK 3790 or later on your XP or later system.
2. Install Microsoft Visual Studio .Net 2003 with C++ suport.
3. Install Compuware DriverStudio 3.1.
4. Create a folder called ‘perforce’ anywhere in the system. 'perforce'
may be replaced with any name, but the absolute path of 'perforce' must
not include any spaces.
5. Copy the driver files from //drivers/main/Common/Crypto/WDMDriver into
'perforce'.
6. On a default DriverStudio install, open the file
c:\Program Files\Compuware\DriverStudio\DriverWorks\source\VdwLibs.vcproj
If DriverStudio is installed in another location, replace
'c:\Program Files\Compuware' with the correct path.
7. Bring up the configuration manager by clicking on
'Build\Configuration Manager'.
8. Set the active solution configuration to 'Win32 WDM Free'.
9. Bring up the DDK Build settings by clicking on
'Tools\Driver Studio\DDK Build Settings'

correctly when the remaining dialog options are no longer grayed out.
11. Build the libraries by clicking on
'Tools\Driver Studio\Build Solution with DDK.exe'
12. Close Driver Studio.
13. Open the file 'Perforce\WdmDriver.sln'
14. Bring up the solution explorer by clicking on
'View\Solution Explorer'
15. Click on 'AESWDMDriver' in the solution explorer window.
16. Bring up the configuration manager by clicking on
'Build\Configuration Manager'.
17. Set the active solution configuration to 'Release'
18. Build the solution using 'Build\Rebuild Solution'
19. After the build, copy the following files to a floppy or a folder.
- LXAES.sys found in 'perforce\sys\objfre\i386'
- LXAES.inf found in 'perforce\sys'
20. You are now ready to install. Go to the installation section.

Known Issues
------------
EEPROM functionality is in the driver but not tested as there are no
EEPROM Geode LX parts yet.
CBC mode is supported in the driver but that will be a Geode LX processor rev 2 feature,
and so this has not been tested yet.
True random number generation is supported in the driver but that will be a
Geode LX processor rev 2 feature and so has not been tested yet.
The writable key cannot be read back from the hardware for security reasons.
The driver doesn't remember this key when it is set. The register is
reset to zero. So entering S3 when the an application has the AES driver
open and the application that has it open is using the writable key will
not work correctly after powering back up. Power off the part will have
to be held off until the application closes the AES device.
