Creating a Splash Screen
The source bitmap files used to create the default splash screens for the vehicle computer are supplied with
the DCP for VC5090c50. These files can be modified using any of the standard windows image editors,
allowing customization for particular customers.
To create a custom splash screen, perform the following steps:
1. Open the Splashcolor.bmp file supplied with the DCP for VC5090c50 using an image editor.
2. Modify the bitmap file and save.
3. Create a splash partition using the steps shown in the Building the Image on page 7-10.
Splash Screen Format
If the default files are not used to create the new splash screens, be sure to preserve the image format. The
formats are as follows:
See Sending the Hex Image on page 7-11 for information about loading the splash screen using TCM and IPL.
Flash Storage
In addition to the RAM-based storage standard on Windows CE vehicle computers, the vehicle computer is
also equipped with a non-volatile Flash-based storage area which can store data (partitions) that can not be
corrupted by a cold boot. This Flash area is divided into two categories: Flash File System (FFS) Partitions and
Non-FFS Partitions.
FFS Partitions
The vehicle computer includes two FFS partitions. These partitions appear to the vehicle computer as a hard
drive that the OS file system can write files to and read files from. Data is retained even if power is removed.
The two FFS partitions appear as two separate folders in the Windows CE file system and are as follows:
Partition Table not Valid -33 The size of flash memory is different than that described in the
partition table. Retry the download with the correct partition table
file.
Invalid file format -34 The file format is invalid. Only Symbol HEX files are supported by
IPL.
