+// Description:
+// T_VIDEOMEMORY.CPP
+// Overview:
+// Test the video driver kernel extension that provides chunk handle to access video memory. 
+// This executable is a second process that is started by the main t_videomemory test process.
+// API Information:
+// HAL, UserSvr
+// Details:
+// - Check that we can get a chunk and that we can read/write the memory belonging to that chunk.
+// - When this process exits, the main process will check that the value has changed in it's copy 
+// - of the chunk.  
+// Platforms/Drives/Compatibility:
+// All.
+// Assumptions/Requirement/Pre-requisites:
+// Failures and causes:
+// Base Port information:
+//
