WS4 Glossary
Backlight
One or more fluorescent lights located behind the LCD panel of an
active or passive display. It illuminates the panel to make the
background brighter and its contents sharper, especially under dim
lighting.
Boot Loader
The WS4 Boot Loader is contained in a 2M Flash EEPROM located on
the system board. Boot loaders are specific to a given CPU and chip set,
in this case, the x86 compatible AMD Geode SC3200 WebPad on a
Chip, which includes the GX1 processor core.
When the WS4 is started, the boot loader performs platform
initialization and runs a Power On Self Test (POST) customized for the
system board hardware. Once the POST is complete, the boot loader
copies the Windows CE image into RAM and starts it.
The boot loader also contains a collection of functions unique to the
WS4 hardware platform. These functions permit access to platform
specific hardware such as memory, IO ports and handles such tasks as
checking the CF card for OS image updates, managing the Operator
LED and controlling backlight brightness.
CAL
Abbreviation for Client Application Loader. The MICROS CAL is a
software utility that assists in the installation of the Workstation 4
application software, then manages the ongoing maintenance of the
operating system and application software. The CAL consists of two
parts, one part resides on the WS4 client and the second part resides
on the system server.
CEPC
Abbreviation for Windows CE Platform Builder. The CEPC is a tool
used to build the WinCE OS image. The CEPC allows the developer to
target a hardware platform like the x86 based WS4 and build it with
selected components appropriate to the platform.
CF Card
Abbreviation for Compact Flash card. Compact Flash is a matchbook
size removable mass storage device first introduced in 1994 by
SanDisk Corporation. CF cards are designed with flash technology,
producing a non-volatile storage solution that does not require a
battery to maintain. Because a CF card is solid state device with no
moving parts, it provides five to ten times the reliability of a
conventional magnetic disk drive.
