Hardware Module Descriptions
Motherboard
Processor/Chip Set
The terminal uses an Intel architecture processor, which permits it to
leverage existing software drivers and applications, as well as provide
the greatest flexibility in choosing an operating system. This provides
several other advantages:
•
Intel 2.5 GHz Celeron Processor, 128kB L2 Cache, 400 MHz front
side bus
•
Intel 2.4 GHz P4 Processor, 512kB L2 Cache, 533 MHz front side
bus
•
Capable of SW MPEG ‐ 1 or MPEG ‐ 2 playback at 30 frames per
second with 22 kHz stereo audio (may be limited by OS
constraints).
•
SoundBlaster
®
‐ compatible audio
•
Expansion capabilities for optional features and future
requirements (PCI bus and USB)
System Memory
The memory used is 266MHz DDR ‐ SDRAM on standard desktop 184
pin DIMMs at 2.5 volts. The board has two DIMM sockets. Release 1.0
supports 1GB maximum memory, which is the limit of the 852GM
chipset. Larger memory configuration up to 2GB is supported with the
852GME chipset.
Memory sizes include 128 MB, 256 MB, 512 MB, & 1 GB non ‐ ECC
DIMMS. The 128MB DIMM used with release 1.0 contains 256Mb
memory chips with 16Mx16 configuration. The other DIMMs used
with release 1.0 contain 256Mb memory chips with 32Mx8
configuration.
The 852GME chip set supports 333MHz DDR ‐ SDRAM.
