Non-FFS Partitions
Non-FFS Partitions include additional software and data pre-loaded on the vehicle computer that can be upgraded.
Unlike FFS Partitions, these partitions are not visible when the operating system is running. They also contain
system information. Non-FFS partitions include the following:
•
Windows CE: The complete Windows CE operating system is stored on Flash devices. If necessary, the
entire OS image may be downloaded to the vehicle computer using files provided by Motorola. The current
OS partition on the vehicle computer is included as part of the TCM installation package. Any upgrades must
be obtained from Motorola. This partition is mandatory for the vehicle computer.
•
Splash Screen: a bitmap smaller than 16 Kb (and limited to 8 bits per pixel) is displayed as the vehicle
computer cold boots. To download a customized screen to display, see
Creating a Splash Screen on page
•
IPL: This program interfaces with the host computer and allows downloading via serial cable any or all of the
partitions listed above, as well as updated versions of IPL. Use caution downloading updated IPL versions;
incorrect downloading of an IPL causes permanent damage to the vehicle computer. IPL is mandatory for the
vehicle computer.
•
Partition Table: Identifies where each partition is loaded in the vehicle computer.
Downloading Partitions to the Vehicle Computer
TCM is used to specify a hex destination file for each partition and download each file to the vehicle computer. This
download requires a program loader stored on the vehicle computer. The vehicle computer comes with a program
loading utility, Initial Program Loader (IPL), stored in the vehicle computer's write-protected flash.
NOTE
8 bits per pixel only applies to splash screen images. Once Windows CE is running, the color density is 16
bits per pixel.
