 == Getting SGX acceleration to work ==
  
-'''Everything should work as in androreas image with the instructions'''
-
-NOTE: as of 2010-09-01, if you build the image yourself like described in the wiki, '''you only have to follow steps 1-5 and 13''' all other steps are already done.
+NOTE: You now *must* do this because the build is set up to expect the SGX drivers to be installed
 
  1. Get and install the omap android sdk as mentioned [http://code.google.com/p/rowboat/wiki/ConfigureAndBuild#Install_the_Android_Graphics_SGX_SDK_on_Host_Machine here].
- 1. Get the ARM tool chain from [http://www.codesourcery.com/sgpp/lite/arm/portal/release830 CodeSourcery].
  1. Change in the gfx_rel_es3.x_android folder (others wont work)
  1. Mount your froyo image with -o loop
  1. Run DISCIMAGE=/mountpoint ./install.sh
- 1. Apply the following patch to your init.rc (root of your froyo image)

- 7. Change to the directory OMAP35x_Android_Graphics_SDK_3_01_00_03/GFX_Linux_KM/eurasiacon/build/linux/omap3430_android/kbuild
- 1. Edit the file build_gfx_kernelmodules
-  a. Change DISCIMAGE= to where your froyo image is
-  a. Change KERNELDIR= to the kernel directory (from archos gpl source package, you need to have the kernel compiled before)
-  a. Change ANDROID_ROOT= to the location where you checked out the openaos froyo source
-  a. Change CROSS_COMPILE= to arm-none-eabi-
- 1. Add the bin subdirectory of the arm tool chain to your path.
- 1. Run ./build_gfx_kernelmodules, compilation of pvrsrvkm.ko will work, afterwards omapfb will fail, but we dont care.
- 1. Copy the resulting file OMAP35x_Android_Graphics_SDK_3_01_00_03/GFX_Linux_KM/services4/srvkm/env/linux/kbuild/pvrsrvkm.ko in  /system/bin/sgx/ in your froyo image
- 1. Copy omaplfb.ko from the extracted archos 2.0.28 firmware to /system/bin/sgx/ in your image. (Version compiled from the archos gpl code should also work)
- 1. Unmount your image, copy to archos and test.
-
-== Optional: backlight support ==
- * copy system/lib/hw/lights.archos.so from the extracted archos 2.0.28 firmware to /system/lib/hw/ in your froyo image.
