VRC 89XX Radio Terminal Product Reference Guide for Embedded Windows
Saving Files and Allocating Memory
The terminal uses a Flash file system and a DRAM file system to save files, run
applications, and allocate memory as necessary.
Flash File System
The terminal has two memory options, either 32MB or 64MB, of non-volatile Flash memory.
•
The 32MB version is divided as, 20MB reserved for Windows CE .NET operating
system; 11MB for storage of programs and program files (Flash file system); 1MB
for storing the boot code and registry.
•
The 64MB version is divided as, 20MB reserved for Windows CE .NET operating
system; 43MB for storage of programs and program files (Flash file system); 1MB
for storing the boot code and registry.
Permanently save your files and programs to Flash by moving them to the following folders
in '\FlashFx Disk\':
•
\ActiveX - ActiveX controls placed in this folder are registered on start up.
•
\CopyToRam - the following folders are available:
•
\Root - applications or files placed in this folder are copied to the root directory.
•
\Startup - applications placed in this folder are permanently stored in Flash but
copied to DRAM and executed on start up.
•
\System - applications or data placed in this folder are permanently stored in
Flash but copied to the \Windows folder in DRAM on start up.
•
\User - user application files.
•
\CAB - CAB installation files are placed into this folder.
DRAM File System
The terminal contains 32MB or 64MB of DRAM backed up by the internal battery for 72
hours. The Windows CE .NET operating system, along with applications in the
\CopyToRam directory, is copied from Flash to DRAM and runs from DRAM when you boot
the terminal.
The DRAM contains the desktop, user settings, and registry. If this information is lost due
to a cold boot or complete discharge of the internal battery, default data is loaded from
Flash on the next start up.
