4 - 22 MC3000 Integrator Guide To create a custom splash screen, perform the following steps: 1. For mobile computers with monochrome screens, open the Splashmono.bmp file supplied with the DCP for MC3000 using an image editor. 2. For mobile computers with color screens, open the Splashcolor.bmp file supplied with the DCP for MC3000 using an image editor. 3. Modify the bitmap file and save. 4. Create a splash partition using the steps in Building the Image on page 4-13. Splash Screen Format If the default files are not used to create the new splash screens, ensure to preserve the image format. Table 4-7 Splash Screen Format Screen Type Dimensions Bit Map File Monochrome 320x320 4 bpp, 16 color grey scale Color 324x324 8 bpp 256 color See Sending the Hex Image on page 4-13 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 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 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 just as it would to the Windows folder. However, the file in the Application folder is in non-volatile storage and is not lost on a cold boot (e.g., when power is removed for a long period of time). Standard tools such as ActiveSync can be used to copy files to and from the FFS partitions. They appear as the "Application" and "Platform" folders to the ActiveSync explorer. This is useful when installing applications on the
