4 - 2 MK4000 MicroKiosk for CE .NET 5.0 Product Reference Guide
RegMerge and CopyFiles
RegMerge and CopyFiles are two device drivers included in the Windows CE OS to assist developers in
configuring the MK4000 following a cold boot. See
Flash Storage on page 5-18 for more information.
Accessing the Windows
®
CE Desktop
If an MK4000 is configured to launch an application on power-up, you can bypass the application at boot-up to
access to the Windows
®
CE desktop.
Network Time Update: SNTP Client
The MK4000 Simple Network Time Protocol (SNTP) client can automatically set and update the MK4000 time and
date through the network. Use this feature to set the system time and date after reboots or power outages. This
feature also ensures consistent time and date stamping across a fleet of MK4000s. The SNTP Client program
queries the specified SNTP server over the network to set the time and date.
The SNTP client shipped with MK4000 WinCE 4.20 is the Microsoft default SNTP Client program. (This is a
change from the WinCE 4.1 operating system, which had a custom SNTP client).
Memory Management
Flash: Nonvolatile (Persistent) Memory
The MK4000 64 MB configuration has 64 MB of available nonvolatile flash memory. 5 MB is committed for platform
partition use to install external driver packs such as RF drivers, and 27 MB is available for developer’s applications
within the application partition (folder). The data partition (folder) has no available memory. The data stored in flash
memory persists through cold boot cycles.
To increase usable persistent (flash) memory, use the Terminal Configuration Manager (TCM) to adjust the
allocation of memory between the application and data partitions. See
Chapter 5, Application Deployment .
Add a PC card to the MK4000 to increase the non-volatile memory available for file storage.
RAM: Volatile (Non-Persistent) Memory
The MK4000 has 128 MB of DRAM volatile memory. Developers can automate control of the device’s RAM
(volatile) memory allocation (storage vs. memory used to run programs) to persist memory allocation settings
through cold boot cycles.
