VGX Windows CE Boot Code

Boot code for the VGX is stored in onboard flash and can be updated in the field. You may need to do this to support performance improvements or newer features of Windows CE builds.

Select the boot code for your system based on the amount of DRAM installed.

Instructions for updating the boot code are found in the Developer's Getting Started Guide.
