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:
• Platform: The Platform FFS partition contains Motorola-supplied programs and Dynamic Link Libraries
(DLLs). This FFS is configured to include DLLs that control system operation. Since these drivers are
required for basic vehicle computer operation, only experienced users should modify the content of this
partition.
• Application: The Application FFS partition is used to store application programs needed to operate the
vehicle computer.
