Internal flash is used for boot loader code and system low-level diagnostics code. Bootloader code
is validated at system startup. The UUID required by CE 5.0 is stored in the boot flash. A second
copy of the bootloader code is stored on the internal SD Flash drive, so that if a damaged
bootloader is detected, it may be re-flashed correctly.

Internal SD Memory Card
The HX2 has one SD card interface for storage of operating system and program code, as well as
persistent storage. The SD slot is inaccessible and ships with an LXE-qualified 128MB (optional
512MB) SD Flash card.

The internal SD flash card supports a FAT file system, via a special device driver, and appears to
the OS as a folder. This allows the contents to be manipulated via the standard Windows CE
interface. Operating system files are hidden on this drive with a terminal unique identifier in the
internal flash, to prevent them being accidentally erased by a user. In addition, the registry hive
files are stored on this device. The amount of Flash memory available for customer use is the
original SD flash card size less 40MB.
