 *$Log: /CE/Platform/Nsc/Drivers/Video/gxvideo/base/CONFIG.CPP $
 * 
 * 21    4/07/00 8:48a Sarma
 * Removed Cyrix Corporation from the legal/confidentail information.
 * 
 * 20    4/06/00 4:09p Sarma
 * Removed personal messages.
 * 
 * 19    4/06/00 3:44p Sarma
 * Initialized the gfx_vidptr only once during object creation.
 * 
 * 18    4/06/00 11:13a Ejapsc
 * took out DhruvaSetReg call because it is not needed here.
 * 
 * 17    4/06/00 10:35a Hari
 * Removed Debug messages.
 * 
 * 16    4/05/00 5:17p Ejapsc
 * added id for device in pdriverdata structure 
 * 
 * 15    4/05/00 4:46p Sarma
 * Set the pDriver member variable only in case of DD_SUPPORT, as it is
 * deifned only in case of directdraw.
 * 
 * 14    3/29/00 2:17p Sarma
 * moved pdriverdata-vtiming and htiming to the end of the function
 * because they were getting updated at the wrong time.
 * 
 * 13    3/29/00 9:26a Sarma
 * Added HALInit as a stub function when no directdraw interface and in
 * directdraw interface this comes from one of the directdraw lib. This is
 * just to keep the export function happy as we cannot modify the *.def
 * file depending upon the env set.
 * Added drirectdraw initialization, and dhruva chipset detection mech.
 * We use 4MB for Directdraw as this seems to be the config for directdraw
 * else directdraw dosen't work. For the non directdraw we still use the
 * 2.5MB memory block. For some reason in the later case the 4MB  usage
 * freezes the screen, so we have two memory sizes.
 * Added durnago based setmode.
 * 
 * 12    10/20/99 9:47a Sarma
 * Added compilation flag FB16BPP to control the depth of the framebuffer.
 * This can be added in "CDEFINES" sources file by adding "-DFB16BPP".
 * Also need to enable CEPC_GX16BPP=1 so that the 1280x1024 is knocked off
 * from the resoultions list. 
 * set CEPC_GX16BPP=1
 * 
 * 11    10/14/99 2:54p Sarma
 * Moved the DEFINES to gxvideo.h for flash.cpp to share the same
 * variables.
 * Deleted the DrvGetModes which was added for test purpose.
 * 
 * 10    9/17/99 2:33p Sarma
 * Setting to possitive sync poll. in 5530 is t set the bits 8/9 on Disply
 * Configuration Register and 0 for negative sync.
 * 
 * 9     9/14/99 11:25a Sarma
 * Use appropraite Horiz/Vert Sync polarity as per the VESA document
 * "Monitor Timing Specifications V1.0 Rev 0.8". Now we have a seperate
 * filed in each resolution data having this information, which will be
 * used in setmode.
 * 
 * 8     8/31/99 2:56p Sarma
 * Modified the "Using DDC". It is found that when in WBT the user seletcs
 * the "Best Using DDC" the Resolution key word in the registry is not
 * set. Resolution not set in the regisrt means automatic assignment and
 * we need to chek the monitor.
 * 
 * 7     8/11/99 4:15p Sarma
 * Added support for 85Hx resoulution for 640x480, 800x600, 1024x768.
 * 1280x1024 dosen't support 85Hz as it is not sable.
 * 
 * 6     7/20/99 2:08p Sarma
 * Added DDC support. This will enable to put the wince is the best
 * available highest resolution supported by the display connected. If
 * display dosen't support or for any other reason if failed it defaults
 * to 640x480x60.
 * 
 * 5     1/13/99 10:11a Sliu
 * Change the video memory size from 4MB to 2.5 MB.
 * 
 * 4     12/01/98 1:14p Sarma
 * No need to create the cursor memory in pDummy which was carried out
 * from s3Trio implementation.
 * The node2D creation has to be sent the screenstride instead of
 * screenwidth, this is true as we opperate on x1024. This is the cause
 * for the RDP not being comming up for 1280x1024 res. This looks the
 * problem for the atifact which used to appear on the bottom of the
 * screen in ICA for 1280x1024.
 * 
 * 3     11/13/98 11:32a Sarma
 * 85 Hz needs to be removed as its not being supported.
 * 
 * 2     11/12/98 3:33p Sarma
 * Added Confidential copyright to files with VSS keywords for
 * log/history.
 * Added DDI interface routine DriverGetModes, but currently not in use.
