7 - 20 MC909X Integrator Guide
1. For mobile computers with monochrome screens, open the Splashmono.bmp file supplied with the DCP for
MC9090c50 using an image editor.
2. For mobile computers with color screens, open the Splashcolor.bmp file supplied with the DCP for MC9090c50
using an image editor.
3. Modify the bitmap file and save.
4. 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 Using IPL 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 mobile computers, the mobile 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 mobile computer includes two FFS partitions. These partitions appear to the mobile 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 Symbol-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 mobile 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 mobile
computer.
Working with FFS Partitions
Because the FFS partitions appear as folders under the Windows CE file system, they can be written to and read
like any other folder. For example, an application program can write data to a file located in the Application folder

pixel.
