+  =================================================================
+  Patch version 0.9 of SDL(Simple DirectMedia Layer) for Nano-X API
+  =================================================================
+  
+  Authors: Hsieh-Fu Tsai, clare@setabox.com
+           Greg Haerr, greg@censoft.com
+
+  This patch is against SDL version 1.2.4.
+  It enhances previous patch 0.8 by providing direct framebuffer
+  access as well as dynamic hardware pixel type support, not
+  requiring a compile-time option setting for different framebuffer
+  modes.
+  Tested against Microwindows version 0.89pre9.
+
+  Older Microwindows versions
+  ===========================
+  If running on a version older than Microwindows 0.89pre9,
+  the following items might need to be patched in Microwindows.
+
+  1. Patch src/nanox/client.c::GrClose()
+  It fixes the client side GrClose(). In the original version, 
+  GrOpen() can only be called once. When the GrOpen() is called at 
+  the second time, the program will terminate. In order to prevent
+  this situation, we need to insert "nxSocket = -1" after 
+  "close(nxSocket)" in GrClose(). If you do not have this problem,
+  you may skip this step. 
+
+  2. Patch src/nanox/clientfb.c to return absolute x,y coordinates
+  when using GrGetWindowFBInfo().  Copy the version 0.89pre9
+  of src/nanox/clientfb.c to your system, or configure
+  using --disable-nanox-direct-fb.
+
+  =============
+  Quick Install 
+  =============
+
+  1. ./configure --disable-video-x11 --disable-video-fbcon \ 
+       --enable-video-nanox \ 
+       --with-nanox-pixel-type=[rgb/0888/888/565/555/332/pal] 
+  2. make clean 
+  3. make 
+  4. make install (as root) 
+
+  ============
+  Nitty-gritty 
+  ============
+
+  --enable-nanox-direct-fb       Use direct framebuffer access
+  --enable-nanox-debug           Show debug messages 
+  --enable-nanox-share-memory    Use shared-memory to speed up 
+
+  When running multi-threaded applications using SDL, such
+  as SMPEG, set THREADSAFE=Y in Microwindows' config file,
+  to enable GrXXX() system call critical section support.
+
+  =============================================
+  Some programs can be used to test this patch.

+
+  =========
+  Todo List 
+  =========
+
+  1. Create hardware surface
+  2. Create YUVOverlay on hardware
+  3. Use OpenGL
+  4. Gamma correction
+  5. Hide/Change mouse pointer
+  6. Better window movement control with direct fb access
+  7. Palette handling in 8bpp could be improved
